 In many organic diseases, for example, diseases that cause impaired blood flow, blood flow insufficiency is improved while cells in the ischemic tissue undergo apoptosis or apoptotic cell death. Furthermore, apoptosis or apoptosis-like cell death in ischemic tissue progresses, and irreversible higher-order dysfunction appears in the living body. This will be described in more detail below, taking as an example a cerebral infarction disease in which the cortical branch of the middle cerebral artery (MCA) is permanently obstructed in cerebrovascular disorders.

When MCA is permanently occluded, nerve cells that are nourished only by MCA, that is, nerve cells in the ischemic core, will be destroyed immediately unless MCA reopens early. It is unlikely that any drug will ever be able to save the brain tissue in the center of ischemia, as it will die and form a cerebral infarction lesion. In addition, WO O 0/3 7 4 8 1

As described in (Brain cells consisting of ginsenoside R b or neuroprotective agent), in the present specification, unlike necrosis (necrosis), the death of slowly progressing neurons is considered.

It is defined as "apoptosis of nerve cells" or "apoptotic-like nerve cell death." On the other hand, in the ischemic penumbra, blood supply from the MCA is completely lost and the vascular network in the same area is lost. Blood supply from the cortical branches of the anterior cerebral artery (ACA) or posterior cerebral artery (PCA) (probably an anastomosis between ACA and MCA or an anastomosis between PCA and MCA) Therefore, it is thought that the nerve cells in the same area are living moribund for some time after MCA occlusion, and of course apoptosis will occur in the ischemic penumbra area if no action is taken. It is a well-known fact that the likelihood of neuronal cell death and the transformation of the entire area to a cerebral infarction lesion is well known clinically, and it is important to be able to rescue the neuronal cells in the ischemic penumbra area. But even if Even if a strong neuroprotective agent can temporarily regenerate the nerve cells in the same area, the nerves in the same area can be used unless the vascular network in the same area that has been broken or reduced due to permanent MCA occlusion is regenerated and reconstructed. Cells are more likely to die at a later time, so they have become ischemic in order to prevent, treat or treat histopathological changes in living tissues that have impaired blood flow, such as cerebral infarction lesions In addition to inhibiting apoptosis or apoptosis-like cell death in cells, it is necessary to regenerate and reconstruct the vascular network around the broken ischemic foci. The molecular groups involved in Isis-like cell death are featured in Experimental Medicine (Vol. 17, No. 13, 1999; Planning, Shigeichi Nagata; Yodosha) and Science in the American Sciences (281, 5381, 1998). Is assembled There is herein B e 1 Among them - the abbreviated below 2 protein group.

B c 1 — 2 proteins have an inhibitory effect on apoptosis or apoptotic cell death (B el — 2, Be 1 -x L, B el — w, M cl — 1, B fl — l ZB od , Nr-13, BRAG-1, BooZDiva, Galectin-3) and those that promote apoptosis or apoptotic cell death (Bax, Bak, Bel — xs , Bad, B ik / N bk, B id, B i m / BodHrk / DP 5 BNIP / NixBokZM tdBlk EGL-1) (Apoptosis proofing method by organ; Editing, Katsunori Otsuki, Takehiko Oji, Kei Watanabe Nanedo, 2000p 16-24). Therefore, in order to prevent apoptosis or apoptosis-like cell death, the expression of the above-mentioned apoptosis inhibitor (Antiapoptotic factors) or the expression of apoptosis-promoting factors (proapoptoic factors) are suppressed. do it. Of course, apoptosis or apoptosis-like cell death can be suppressed by simultaneously regulating the expression of a plurality of apoptosis-related factors described above.

 Among the Bc1-2 protein group, Bc1-1x> J is particularly abundantly expressed in all living tissues such as mature brain / nervous tissue, immune tissue, hematopoietic tissue, skin tissue, and cardiac muscle tissue. It plays an essential role in the survival of cells.

It is said that the mitochondria-related protein Be 1 — inhibits the binding of A paf 1 to procaspase 9 by binding to A pafl (Adams JM and Cory S. When the B e 1 protein is reduced or its function is reduced, A paf 1 dissociates from the B c 1 — X protein and binds to procaspase 9 to release mitochondria. It is believed that procaspase 9 is activated in conjunction with cytochrome C leakage (Adams JM and Cory S. Science, 281, 1322-1326, 1998). Once procaspase 9 in the cytoplasm was activated, caspase 9 and caspase 3, the final cell excecutioner, were subsequently activated, These proteolytic enzymes accelerate the process by which cells self-lyse and die (apoptosis). Perhaps activation stage of procaspase 9, there is a high possibility that the cells are destined death is determined, B e 1 - x _L be further stop the activation of pro-caspase 9 increased expression agent, cell It is considered a good measure to prevent death. In addition, if there is a compound that not only promotes expression of Bc1—X but also suppresses the expression of caspase-3, which is the final excecutioner of cells, an anti-apoptotic agent It is thought that the value of use as it increases. Of course, transcription factors that induce the expression of Bel— (eg, NFKB, STATS, etc.) may be increased to prevent cell death. Factors relating to the neovascularization, regeneration or remodeling of blood vessels include the molecular groups described in Experimental Medicine (Vol. 17, No. 6, 1999; Planning, Masashi Shibuya; Yodosha), such as VEGF, VEGFR, Angiopoetin, T ie, ephrin—B2, b FGF, Eph—4B, CXCR4, Shc, SCL, ets-10, Erb—B3, NDF, PDGF, PDGFR, HGF, HGFR, Among them, HIF-1 and the like are mentioned, and among them, VEGF (vascular endothelial growth factor) is known to play a central role in vascular regeneration, regeneration or remodeling. More specifically, VEGF is used for the proliferation of vascular endothelial cells, migration or migration of endothelial cells, luminal formation, coagulation and fibrinolysis of endothelial cells such as tissue factor and plasminogen activator. It is involved in the renewal, regeneration or remodeling of blood vessels by promoting production of protein, expression of cell adhesion molecules in endothelial cells, and expression of Bc1-2 in endothelial cells. Therefore, if a compound that promotes the expression of VEGF is found, it can be said that it can be used as a pharmaceutical composition for promoting the regeneration and / or reconstruction of blood vessels. Incidentally, HIF-1 (hypoxia inducible fact or-1) is known as one of the transcription factors that induce the expression of VEGF. The outline of the regeneration and Z or remodeling of blood vessels is described in Japanese Patent Application No. 2000-248584 and PCT / JP0Z055554. Naka, Tanaka) describes the wound healing phenomenon as an example.

 The dihydrozincenoside R bi of the present invention is represented by the above-mentioned structural formula. The dihydrozincenoside R bi is PCT / JP00 / 04201 or PCTZJP0 / 05555. Ginsenoside R b can be prepared as a raw material according to the method described in No. 4.

 A ginsenoside derivative such as dihydrozincenoside Rb of the present invention can be used in a free form, but it can also be used with an appropriate salt. They can also be used as solvates such as hydrates thereof.

The concentration of ginsenoside derivatives or metabolites thereof such as dihydroginsenoside Rbi of the present invention is preferably low, and more specifically, the concentration of extracellular fluid in the affected tissue is 100 g / m 1. (About 90 ^ M) or less, preferably 100 ng Zm1 (about 90 nM) or less, more preferably I ng Zml (about 0.9 nM) or less, and still more preferably 10 ng Zml (about 0.9 nM) or less. The density is less than 0 fg / m1 (about 90 fM). When a ginsenoside derivative such as dihydrozincenoside Rbi of the present invention is used as a preparation for intravenous administration or an external preparation for skin, the preparation should be prepared so that the concentration of extracellular fluid in the affected area of the patient becomes the above-mentioned concentration. Adjustment is preferred. The pharmaceutical composition and preparation of the present invention can provide a sufficient effect even when the concentration of extracellular fluid in the affected area is about 0.001 to 100 fg / m 1. The concentration of natural ginsenosides in the extracellular solution is described in PCT / JP 00/04102 or PCT / JP 00/055 It is described in No. 54.

 The preparation for intravenous administration containing the ginsenosides of the present invention may be any one which can be directly administered intravascularly, preferably intravenously, and even if it is a single intravenous injection preparation, it may be intravenously administered. It may be a preparation for continuous administration. It may also be a dosage form that can be used by adding to an intravenous formulation such as a point application composition. The pharmaceutical composition of the present invention is preferably a preparation for intravenous administration, an external preparation for skin, or an external preparation for mucosa, preferably a local external preparation for lesions, a local injection for lesions, an oral administration preparation, an intraarticular injection preparation, an intrathecal injection preparation, Intra-arterial preparations, nasal drops, eye drops, eye ointments, ear drops, suppositories (including vaginal suppositories), subcutaneous injections, intradermal injections, intramuscular injections, inhalants, sublinguals, transdermal drugs Any or known administration route can be selected. It may also be used as a sustained release agent.

 As shown in the examples below, dihydrozincenoside R bi was administered intravenously to reduce cerebral vascular injury, especially the area of cerebral infarction lesions, to about 1Z3 in the non-administration group, and furthermore, the cell death suppressing gene product B It has a unique mechanism of action that enhances c11- ^ expression and suppresses caspase-3 expression, and protects all types of cells, especially brain and nerve cells, as well as acute and chronic cerebral infarction. It can also be used as a neuroprotective drug for cerebral hemorrhage, subarachnoid hemorrhage, acute and chronic phases of cerebral embolism, and cerebrovascular disorders such as transient ischemic attacks. That is, ginsenoside derivatives such as dihydroginsenoside Rb, metabolites thereof, and salts thereof are substances that can be intravenously drip-injected into ambulances for patients suspected of having cerebrovascular disorders such as stroke. Natural ginsenosides such as ginsenoside Rbi also have the same 'efficacy' applications as those of ginsenoside derivatives such as dihydrozincenoside Rb, as described in WO 00/374841.

The intravenous administration of the dihydrozincenoside Rb of the present invention not only reduces the area of cerebral vascular injury, particularly the cerebral infarction lesion area to about 1Z3, but also reduces the area around the ischemic lesion (is chemi c penumb ra) by intravenous administration. Disruption 'It is said that the reduced vascular network can be returned to almost normal state through enhanced VEGF expression. Therefore, intravenous administration of ginsenoside derivatives such as dihydrozincenoside R bi promotes regeneration or remodeling of the broken or reduced cerebral vascular network after a stroke, and thus, after the end of intravenous administration of the pharmaceutical composition. To make the rescued brain tissue function normally over time Can be. That is, the dihydrozine senoside R bi of the present invention not only has a direct protective effect on nerve cells such as enhancement of Bc 1 _ protein expression, suppression of caspase 3 expression and suppression of apoptosis-like nerve cell death, but also cerebral vascular Regeneration of the blood vessels, including the net-Protecting living tissues such as the brain that has become ischemic through indirect and long-lasting defense mechanisms rather than remodeling. Furthermore, the pharmaceutical composition comprising ginsenosides of the present invention induces the expression of BeI- or VEGF by activating the cell transcription factor STAT5 or transcription factor HIF-1. Therefore, the pharmaceutical composition of the present invention comprises cytokines capable of activating the transcription factor STAT 5 (interleukin 2, interleukin 3, interleukin 5, interleukin 7, interleukin 9, interleukin 9, inleukin leukin). It can be said that it has the same action as granulocytes, macrophages, colonies (stimulators of erythropoietin), growth hormone, prolactin, etc. In addition, the pharmaceutical composition of the present invention is thought to induce the transcription of 0-casein, oncostatin M, and the like, through activation of STAT5. On the other hand, the pharmaceutical composition of the present invention provides not only VEGF but also erythropoietin, transferrin, transferrin receptor, VEGF receptor (FLT-1), glycolysis through activation of the transcription factor HIF-1. It can also be said to induce the expression of various system enzymes, type 1 and type 3 glucose transporters, adenylate kinase 3, hemoxygenase or tyrosine dehydrogenase.

 In general clinical settings, higher nervous function is continuously reduced despite no new seizures after cerebrovascular disorders, and the so-called sequelae of stroke continue to worsen. One reason for this is that the regeneration or remodeling of the cerebrovascular network that has collapsed or diminished in a stroke attack is sometimes inadequate. In order to improve such sequelae after stroke, intravenous, anal, vaginal, nasal, sublingual, or ocular administration of ginsenoside derivatives such as dihydrozincenoside Rbi has been remarkable. It is expected to show the effect.

As described above, ginsenoside derivatives such as dihydrozincenoside Rbi of the present invention have a novel effect of regenerating, regenerating and remodeling blood vessels through enhancement of VEGF expression. Disease, disease or condition (eg, transient cerebral ischemic attack, diabetes, heart failure, cardiomyopathy, thrombophlebitis, fracture, neurodegenerative disease, glue Primary disease, cerebrovascular disorder, cerebral hemorrhage, subarachnoid hemorrhage, cerebral infarction, arteriosclerosis, peripheral circulatory failure, immunodeficiency disease, AIDS, myelodysplastic syndrome, osteoporosis, knee osteoarthritis, osteoporosis, Angina pectoris, myocardial infarction, vasculitis, central retinal arteriovenous obstruction, liver, kidney, heart, cerebral ischemia reperfusion injury, vascular injury, poor blood color, coldness, physical fatigue, anorexia, frail constitution, stomach and intestinal weakness , After illness, Behcet's disease, diabetic neuropathy, physical fatigue, infection, mosaic disease, subdural hematoma, cyanosis, lympha edema, edema, cerebral edema, hemorrhoids, wound, burn, frostbite , Electric shock, laser injury, disseminated intravascular coagulation, secondary anemia, hypotension, hemolytic uropathy, circulatory disease, menopause, hemorrhagic shock, hereditary spherocytosis, corneal wound, Radiation damage, UV damage , Pressure sores, diabetic skin ulcer, diabetic retinopathy, diabetic nephropathy, anemia, renal anemia, preeclampsia, hypertension, neonatal asphyxia, orthostatic dysregulation, cirrhosis, hepatitis, nephritis, regenerative disorders Anemia, thrombotic thrombocytopenic purpura, idiopathic thrombocytopenic purpura, aortitis syndrome, sudden deafness, purpura, acute peripheral arterial occlusion, defecation disorder, dysuria, alopecia, obstructive thromboangitis, obstruction It is effective for atherogenic sclerosis, Reino's disease, sexual dysfunction, autonomic nervous disorder, Reino's syndrome, etc. For example, when performing photocoagulation therapy for diabetic retinopathy, systemic administration of ginsenoside derivatives such as dihydrozincenoside R bi promotes retinal vascular regeneration and reconstruction after photocoagulation. . Of course, in these diseases in which blood flow disorder is the main symptom, it is also possible to suppress cell death in the tissue exposed to the blood flow disorder through enhancement of Be1-X expression and / or suppression of caspase-3 expression. It is an unforgettable indication of dihydrozincenoside R b. Therefore, ginsenoside derivatives such as dihydroginsenoside Rb are expected to reduce tissue damage through at least two mechanisms of action even in peripheral blood flow disorders. Natural ginsenosides such as ginsenoside Rbi have similar effects, uses and effects. Furthermore, as described in PCT / JP 00/055554, ginsenosides have an excellent effect in preventing, treating or treating the above-mentioned diseases through the action of promoting the regeneration and reconstruction of living tissues. Is shown.

Natural ginsenosides, such as ginsenoside Rbi, also have the same 'use' effect. Many of the above-mentioned diseases that cause apoptosis, cell death, or apoptosis-like cell death include blood flow impairment, although the degree of the disease varies to some extent, and therefore, they are included in the category of diseases that cause blood flow impairment. in addition Is also good.

 As shown in the Examples below, dihydrozincenoside Rb was administered intravenously at a daily dose of 6 ig or 0.6 g in a permanent occlusion rat (body weight of about 300 g) in the middle cerebral artery cortical branch (MCA). Reduces the volume of cerebral infarction to about one third of the non-administration group. In addition, the dihydrozine senoside Rbi of the present invention shows excellent effects and efficacy on spinal cord injury rats even at a dose of 1.2 μg Z-day as shown in the Examples below. That is, low-dose ginsenoside derivatives such as dihydroginsenoside Rbi, as well as natural ginsenosides such as ginsenoside Rbi, are associated with various symptoms and conditions associated with spinal cord injury or nerve trauma, such as neurology.

 Based on these experimental results, the optimal intravenous dose of ginsenoside derivatives for patients with a blood flow disorder of 60 kg or a patient with cell death is estimated Calculated from 0.12 to 1.2 mg per day. Therefore, the daily systemic dose (including oral dose) of the pharmaceutical composition of the present invention to a human or a vertebrate weighing 60 kg depends on the individual differences and the medical condition of the patient. lmg or more, preferably lmg or more, more preferably 10 mg or more. The pharmaceutical composition of the present invention has few side effects, and the upper limit of a systemic dose (including an oral dose) for the prevention, treatment or treatment of the above-mentioned disease or condition can be considerably large. It is 20 g or less, preferably 2 g or less, more preferably 0.2 g or less. When the pharmaceutical composition of the present invention is systemically administered for the prevention, treatment or treatment of the above-mentioned diseases, the lower limit of the dose is around 0.01 fg / day, as judged from the effective extracellular fluid concentration.

 In addition, as a compound derived by chemically modifying ginsenoside compounds such as naturally occurring ginsenoside R bi by chemical means, the chemical structure of the natural ginsenosides described above was modified in the following manner. (In the present specification, these compounds are referred to as “ginsenoside derivatives”.)

That is, (1) those obtained by reducing the double bond of the side chain (carbon chain) bonded to the steroid-like skeleton (damaran skeleton) of ginsenosides (so-called dihydrazine genosides) and geno or ginsenosides Saccharides reduced to itols, or those obtained by acylating or acetylating them (2) those obtained by acylating or acetylating the hydroxyl group of dincenosides, (3) acylation or acetylation In addition to acetylation, a double bond in the side chain (carbon chain) is converted into a single bond, and an arbitrary functional group (for example, one or more hydroxyl groups) is bonded to the double bond, or two hydroxyl groups are dehydrated.

The above-mentioned ginsenoside derivatives are described in PCT / JP 00/04102, PCT / JP 00/0555554, and Japanese Patent Application No. 2004-17034509. It is considered that all of the effects, indications, and uses of ginsenoside Rb or dihydrozinesenoside Rbi described in Japanese Patent Application No. 2000-40032 are combined. It should be noted that an attempt to create a compound having a new medicinal effect by using a natural ginsenoside, which is difficult to synthesize at present, as a lead compound was first performed by the present inventors.

 Among ginsenosides, oleanolic acid having a slightly different chemical structure, for example, ginsenoside Ro (chixessaponin V), may be chemically modified in the following manner. In other words, (1) a steroid-like skeleton of ginsenosides (oleanoic acid) or a substance obtained by reducing one double bond existing in the chemical structure of aglycone (so-called dihydrozinenosides); (2) (1) A hydrogen atom at the reduction site substituted with an arbitrary functional group (for example, a hydroxyl group, an alkyl group, an aryl group, etc.), (3) an esterified propyloxyl group, and (4) an acylated or acetylated hydroxyl group.

The pharmaceutical composition of the present invention can of course be used as a veterinary pharmaceutical composition for vertebrates, but in this specification, the expression "veterinary pharmaceutical composition" will be omitted. In addition, the pharmaceutical composition of the present invention may be used as a veterinary pharmaceutical composition for invertebrates such as fish, shrimp, oysters and shellfish. Of course, the pharmaceutical compositions of the present invention include veterinary pharmaceutical compositions.

 Next, the low-dose and low-concentration ginsenosides of the present invention have a therapeutic effect on cerebrovascular disorders, a blood vessel regeneration / reconstruction promoting effect, a wound therapeutic effect, a spinal cord injury therapeutic effect, a VEGF expression enhancing effect, Bc1—X. The expression enhancing effect, caspase 3 expression suppressing effect, transcription factor STAT5 • HIF-1 activating effect, etc. will be described in detail based on specific examples. For this reason, description will be made based on experimental results using dihydrozincenoside R, which is a typical ginsenoside derivative of the present invention, and ginsenoside Rbi, which is a typical natural ginsenoside.

 The present inventors first prepared dihydrozincenoside Rbi.

 The production examples and NMR data of dihydrozincenoside Rbi are shown below. (1) 10 mg of 10% Pd / C (palladium charcoal) is weighed and placed in a two-necked flask equipped with active oxygen. (2) 1 ml of methanol (special grade) is added and suspended. . (3) Attach a hydrogen balloon (about 1.1 atm) and activate the catalyst at 0 ° C for 30 minutes.

 () Dissolve 9.9 mg of ginsenoside Rbi1 in 1 ml of methanol and inject with a syringe. (5) Stir the mixture vigorously with a magnetic stirrer at 0 ° C for 10 1/2 hours. (6) Filter the reaction mixture through filter paper and a 0.45 im membrane filter. (7) Remove methanol under reduced pressure. (8) After dissolving in 10 ml of pure water and freeze-drying, 19.1 mg (97% yield) of dihydrozincenoside Rbi was obtained as a white powder. The melting point of dihydrozincenoside Rbi is 193-195 <By the way, the melting point of ginsenoside Rbi is 197-198 ° C (literature value). Fig. 1 shows the NMR chart (400 MHz, CDaOD) of dihydrozincenoside Rbi.

Next, the present inventors first examined the concentration at which the dihydrozincenoside R bi obtained by the above-mentioned method exerts a favorable effect on cells. For this reason, the present inventors have developed apoptosis or apoptosis-like neurons in cultured neurons. The concentration at which death was suppressed by dihydrozincenoside R b was examined. The present inventors (Sakanaka, Tanaka) show that short-term exposure of cultured neurons to the nitric oxide donor, nitropurs sodium (SNP), can result in neuronal apoptosis or apoptotic neuronal death. (Toku K. et al., J. Neurosci. Res., 53, 415-425, 1998). Using this culture experiment system, the present inventors have found that ginsenoside Rb has an apoptosis-like or apoptosis-like neuron at an optimal extracellular solution concentration of 110 fg / m1. It has been found that deterrence can be suppressed (WO 0 Z 37481). Therefore, the neuroprotective effect of dihydrozine senoside Rb was examined using a similar experimental system.

 Nerve cells were isolated from the fetal cerebral cortex of a 17-day-old rat fetal cerebral cortex using trypsin EDTA and plated on a polyellidine-coated 24-well plate. After culturing for 16 hours in Dulbecco's modified Eagle's medium (DMEM) containing 10% fetal calf serum, the culture solution is subjected to neurons containing insulin, transferrin, etc. The medium was replaced with a serum-free medium for culture and cultured for 3 to 4 days. On day 3 or 4 of culture, sodium nitroprusside (SNP) was added at a concentration of 300 M and incubated for 10 minutes. Thereafter, the culture solution was replaced with Eagle's minimum essential medium (EMEM) containing dihydrozinosine Rbi (0 lng / ml) and bovine serum albumin. Sixteen hours after SNP loading, neurons were lysed using Laeli's sample buffer for electrophoresis, polyacrylamide gel electrophoresis was performed, and the electrophoretic proteins were transferred to nitrocellulose membrane. Immun blotting was carried out using an antibody against. Immunostained MAP2 bands were analyzed by densitometry to quantify neuronal viability and Z or process elongation. The results are shown in FIGS. 2 and 3. The details of the experimental technique of the MAP2 immunobolot are described in the published papers of the present inventors (Sakanaka and Tanaka) (Wen, TC. Et al., J. Exp. Med., 188 , 635-649, 1998)

FIG. 2 is a photograph instead of a drawing, showing the result of the immunoblot of microtuble-associated protein 2 (· ΜAP 2). The first lane from the left is the control cultured neurons, with a clear MAP 2 band. (Ie, a marker band of nerve cells). SNP treatment caused many neurons to undergo apoptosis or apoptosis-like neuronal death, so the MAP2 band was clearly weakened, as in the second lane from the left. When dihydro rosin senoside Rb: was added to the culture medium at a concentration of 0.01 fg / m1 (lane 3) to IngZml (lane 7), neuronal cells induced by SNP Apoptosis or apoptosis-like neuronal cell death was clearly suppressed, and as a result, a strong band of MAP2, which is an indicator of neuronal cell survival and / or process elongation, was observed. Figure 3 shows a densitometric analysis of the results obtained by repeating the MAP2 immnoblot experiment five times. As shown in Fig. 3, dihydrozincenoside Rb in the optimal extracellular fluid concentration range of 0.01 fg / ml to lng / m1 significantly suppressed apoptosis of neurons or apoptosis-like neuronal death It turned out to be. That is, dihydrozincenoside R bi has a favorable anti-cellular activity, particularly against nerve cells, in an optimal extracellular solution concentration range which is considerably wider than that of ginsenoside R b described in WO 00/37481. It is thought to exert an apoptotic effect. Presumably, ginsenoside derivatives such as dihydrozincenoside Rb also promote nervous tissue regeneration and / or remodeling by extending neurites. Therefore, ginsenoside derivatives such as dihydrozincenoside Rbi have an extracellular solution concentration of 100 g / m1 (about 90 M) or less, preferably 100 ng / m1 (about 90 nM) or less, more preferably I n gZm l (about 0.9 n M) or less, and even more preferably 0.OOOO li gZm l (about 0.0 0 0 0 0 0 9 f M) to 100 It is considered that by suppressing the apoptosis or apoptosis-like cell death of the cells at the rate of 0.000 fg / m 1 (about 900 fM), an excellent cytoprotective action is exhibited. That is, ginsenoside derivatives such as dihydrozincenoside Rbi are thought to protect cells of living tissues exposed to impaired blood flow through anti-apoptotic action. Ginsenoside derivatives such as dihydrozincenoside Rbi are used for transplantation tissues 細胞 organ cells (stem cells, fertilized eggs, embryos, ES cells, skin keratinocytes, etc.), cells derived from any tissue, frozen cells for transplantation, transplantation It is also considered useful for protecting or preserving frozen tissues for use, frozen organs for transplantation, blood cell components for blood transfusion, platelets, and germ cells (frozen ovum, frozen sperm, frozen fertilized egg). * In Fig. 3 indicates P <0. 001 indicates **, and ** indicates P <0.0001. Statistical analysis is based on the post hoc test of 8 1 ^ 0 + 3 (; 116 {6.

 As described above, ginsenoside derivatives such as dihydrozincenoside Rb can be used for cells, particularly neuronal cells, in an optimal extracellular concentration range that is considerably wider than ginsenoside Rbi described in WO 00/37481. Inhibition of apoptosis or apoptosis-like neuronal cell death has been shown in an in vitro experimental system, but dihydrozine cenoside R has also been demonstrated in an in vivo animal experimental system that actually impairs blood flow. The present inventor next examined whether or not ginsenoside derivatives such as b show excellent effects similarly to the ginsenoside R bi described in WO 00/37481. For this reason, for example, cerebrovascular disorder is selected as a disease or condition causing blood flow disorder as follows, and intravenous administration of dihydrozincenoside Rbt, which is one of the ginsenoside derivatives, is effective for cerebrovascular disorder, especially for cerebral infarction. I checked whether it was effective for treatment.

 About 12 to 16 weeks of age, male stroke-prone spontaneously hypertensive rats (SH—SP rats, body weight 280 to 320 g) were used. The animals were housed in a 12-hour light-dark cycle room. Water and food were available ad libitum. Under inhalation anesthesia, the left middle cerebral artery cortical branch (MCA) of the animal was coagulated and dissected. A single intravenous infusion (6 g or 0.6 g) of dihydrozine senoside Rb immediately after permanent MCA occlusion, followed by continuous intravenous dihydrozine senoside R bi for 24 hours using an arzami diosmotic pump Injections (6 g Z days or 0.6 Mg / day) were performed (n = 6). The details of this experimental technique are described in published papers by the present inventors (Sakanaka and Tanaka) (Igase K.e't al., J.

Cerebr. Blood Flow Metab., 19, 298-306, 1999).

 Control animals in which MCA was permanently occluded (ischemic control animals) were intravenously administered only the same amount of saline (vehicle, carrier or vehicle) (n = 7). Twenty-four hours after permanent MCA occlusion, a lethal dose of pentobarbi was injected intraperitoneally into rats. Immediately after the animal died, the brain was removed and a 2 mm thick forehead section was prepared. The sections were combined with 1% 2,3,5 chloride-triphenyl-tetrazolium chloride (2,3,

The sample was immersed in a solution of 5-tripenyl-tetrazolium chloride (TTC) for 30 minutes at 37 ° C and fixed with 10% formalin for 12 hours or more. The results are shown in FIG. 4 and FIG. Fig. 4 shows two cases of administration of saline, and Fig. 5 shows dihydrozine cenoside R bi S Two cases in which g / day was administered intravenously are shown.

 As shown in FIG. 4, in the rat to which saline was administered after MCA permanent occlusion, a white cerebral infarction lesion not stained with TTC was clearly observed in the left cerebral cortex. On the other hand, as shown in FIG. 5, cerebral infarction lesions were significantly reduced in rats administered intravenously with dihydrozincenoside Rb after MCA permanent occlusion.

 The cerebral infarction area of the cerebral infarction rat (n = 6) administered intravenously with dihydrozincenoside Rbt and the cerebral infarction area of the cerebral infarction rat administered vehicle (vehicle (vehicle or vehicle)) alone (n = 7) was compared. The results are shown in FIG. As shown in Fig. 6, compared with the cerebral infarction area in the cerebral infarction group given vehicle (saline), dihydrogen senoside R b! The cerebral infarction area (infarct area) of the treated cerebral infarction group was reduced to about one third. In the statistical analysis method shown in Fig. 4, the ** mark indicates 0.01 according to the Mann-Whitney test.

 From the above, the therapeutic effect of dihydrozincenoside Rb on cerebrovascular disorders, especially the therapeutic effect on cerebral infarction, is superior to the effect of ginsenoside Rbi disclosed in WO 00/37481. Turned out to be. In other words, it can be said that ginsenoside derivatives such as dihydroginsenoside Rbi are effective and efficacious in diseases or conditions that cause impaired blood flow such as cerebrovascular disorder and cerebral infarction. In addition, it was considered that ginsenoside derivatives such as dihydrozincenoside R bi promote regeneration and / or remodeling of cerebral blood vessels, similarly to ginsenoside R bi described in WO 0 Z4 686. . Therefore, the present inventor further doubled the intravenous dose of dihydrozine cenoside Rb (single dose of 12 ig and then dosed on the following day) to determine whether a similar effect for treating cerebral infarction could be obtained. Investigation revealed that no unexpectedly good effects were observed. In other words, ginsenoside R bi showed an excellent therapeutic effect on cerebral infarction even in a 6-day dose to SH-SP rat with a body weight of about 300 g in WO 00/374814. However, it was considered that ginsenoside derivatives such as dihydrozincenoside Rb do not necessarily exert a cerebral infarction treatment effect and / or a cerebral blood vessel regeneration / remodeling promotion effect at such a high dose.

Therefore, the optimal dose of dihydrozincenoside R for cerebral infarction rats weighing about 300 g is lower than the optimal dose of ginsenoside Rb. It was considered to be less than 0 z gZ days, preferably less than / day. Thus, in culture experiments, dihydroginsenoside Rb inhibits neuronal apoptosis or apoptosis-like neuronal death in a broader concentration range than ginsenoside Rb, but in vivo (in vivo). Dihydrozincenoside Rb has excellent cerebral infarction treatment effect and cerebral blood vessel regeneration / reconstruction in the same dosage amount as ginsenoside Rbt or as low as 1/10 to 1/100 It can be said that it exerts a promoting effect. However, other ginsenoside derivatives such as dihydroxyxenosenoside R bi or epoxy ginsenoside R bi may be used at a dose and concentration that is equal to or approximately 100 times higher than ginsenoside Rb. Effect similar to b · Efficacy is expected.

 The present inventors have further investigated whether low doses of dihydrozine cenoside Rb also have a favorable effect on neurological trauma, such as spinal cord injury, which causes impaired blood flow. By the way, neurological trauma such as spinal cord injury and head trauma also results in impaired blood flow due to rupture of blood vessels and edema of brain and spinal cord tissues, resulting in irreversible higher-order neuropathy. Therefore, the present inventors have taken spinal cord injury as one of the diseases causing blood flow disorder and decided to examine the effect of dihydrozine cenoside Rbi on spinal cord injury. For this reason, the following is an experimental example in which dihydrozine cenoside Rb was infused intravenously into a spinal cord injury rat (body weight: about 300 g) for 7 days at a dose of 1.2 gZ days.

 Under oral inhalation anesthesia with laughter, 20 g of pressure was applied to the lower thoracic spinal cord of the rat for 20 minutes, and after 30 minutes or more, dihydrozine cenoside R b was injected into the left femoral vein. 2 ig) was injected once, and dihydrozine cenoside R bi (l. day) was continuously administered to the same vein using an Alzamini osmotic pump for 7 days. Control animals received the same amount of saline (vehicle, carrier or vehicle) on a similar schedule. The results are shown in FIGS. 7 and 8.

The left photographs in Figs. 7 and 8 show the saline administration rats on the second day after spinal cord injury, and the right photographs in Figs. 7 and 8 show dihydrozincenoside Rb1.2 at the same time. g / day) dosing rate is indicated. As shown in the left-hand photographs of Figs. 7 and 8, the saline administration rat with 20 g of pressure applied to the lower thoracic spinal cord for 20 minutes was used not only on the day of spinal cord injury but also after spinal cord injury. He also exhibited paraplegia on both legs during the day. However, if 20 g of pressure was applied to the lower thoracic cord for 20 minutes and then dihydrozincenoside Rt was administered intravenously at a dose of 1.2 ^ g / day, the paraplegia of the lower limb was reduced on the day of spinal cord injury. On the second day after spinal cord injury, paraplegia of both lower limbs improved remarkably, and the rat was able to stand up while holding on to an object, as shown in the right photographs in Figs. 7 and 8. Now you can. Dihydrozincenoside Rbt at a dose of 8 g / day, 16 iZg / day or 60 / _t g / day administered intravenously to rats with spinal cord injury did not show any significant effect. .

 Based on the above, ginsenoside derivatives such as dihydrozincenoside R bi are significantly superior to spinal cord injuries even when compared to ginsenoside R b described in WO 00/46808. · It has been found to be effective in treating nerve trauma. Furthermore, the optimal dose of dihydrozincenoside Rb, for a spinal cord injury rat weighing 300 g, was considered to be around 1.2 ig to 2.4 ^ g / day or less. That is, when dihydrozincenoside Rb is used as a pharmaceutical composition for treating nerve trauma, head trauma, and spinal cord injury, the optimal dose is WO 0 Z 4 680 or PC TZ JP 0 Optimal dosage of ginsenoside Rbi described in 0/04201

(60 g / day for a rat weighing 300 g) was found to be about 25 times or about 50 times less or less. As described above, dihydrozinc senoside R bi can be produced from high-purity ginsenoside R bi at a 97% yield, so that dihydrozin senoside R b is more efficient than ginsenoside R bi. It can be used to prevent, treat, and treat neurological trauma, stroke, and other brain disorders that cause blood flow disorders.

Based on the above experimental results using cerebrovascular accident (cerebral infarction) model animals and spinal cord injury model animals, ginsenoside derivatives such as dihydrozincenoside Rbi indicate that blood flow disorders are caused by diseases such as cerebrovascular disorders and spinal cord injuries. It has been invented to be a pharmaceutical composition for prevention, treatment or therapy. Possibly, Jihi Drosin Senoside R b! Derivatives such as ginsenoside derivatives, which inhibit cell apoptosis or apoptotic cell death and promote vascular regeneration / remodeling, can cause blood flow disorders (eg, cerebrovascular disorders, head trauma) , Nerve trauma, spinal cord injury, etc.). Now, by describing the pathology of spinal cord injury a little more, the effects and efficacy of ginsenoside derivatives such as dihydridine senoside Rb will be added. When a spinal cord injury occurs due to a pressure load on a segment of the spinal cord, for example, the lower thoracic cord, not only the gray matter nerve cells in the area but also the white matter pathway in the area are damaged. By the way, the white matter pathway consists of the nerve cell processes (ie, axons or dendrites) and the myelin from oligodendrocytes that insulates them (myelin). Impairment of the white matter pathway further extends to the distal (caudal) side, and secondary degeneration or apoptosis of the cell originating the pathway, ie, the upper nerve cell body that projects fibers into the pathway. Causes cis-like cell death. In this way, impairment of the white matter pathways of the lower thoracic spine under pressure overload is caused by the origin of the pathways and the pathways below the lower thoracic spinal cord (ie lumbar spinal cord, sacral medulla). Causes paralysis of the lower limbs by inducing secondary degeneration. Injury of the lower thoracic spinal cord disrupts innervation of the lumbar spinal cord and sacral cord from the upper brain, and secondary degeneration of neurons, that is, apoptotic cell death, also progresses in the gray matter of the lumbar spinal cord and sacral cord. The paralysis of both lower limbs becomes irreversible. It is known that apoptosis and demyelination of oligodendrocytes occur in parallel with such symptoms (Crown, M. J. et al., Nature Med., 3, 73-76, 1 997).

 In addition, in spinal cord injury, in addition to the above-mentioned disorders specific to nerve tissue, blood flow disorders, and blood vessel injuries, neuropathic bladder, cerebral edema, nerve tissue edema, edema, dysuria, Defecation disorders, sexual dysfunction, skin ulcers, pressure sores, etc. occur. Many of these diseases, symptoms, or conditions are caused by spinal cord injuries that cause damage to not only motor nerves, but also autonomic nerves and sensory nerves, resulting in dysfunction and impaired blood flow in the area. Conceivable. It is also known that vascular damage and edema easily occur when nerve tissue (spinal tissue) is subjected to excessive mechanical or physical pressure. The above-mentioned symptoms, diseases, lesions or conditions associated with spinal cord injury are also found in head trauma to varying degrees.

Therefore, judging from the experimental results of the present invention that dihydrozincenoside Rb elicits a bedridden spinal cord injury rat at low dose and low concentration, ginsenoside derivatives such as dihydrozinosenoside Rb are WO 0 Spinal cord injury at doses / concentrations equivalent to or wider than the ginsenoside R bi described in 0/4866 08 It is considered to be useful for the prevention, treatment and treatment of the above-mentioned conditions, symptoms and diseases caused by wounds and nerve trauma (including head trauma). Ginsenoside derivatives such as dihydroginsenoside Rb ^ are expected to be indicated for the following conditions, symptoms, and diseases: secondary degeneration of nerve tissue, edema, brain edema, edema of nerve tissue, oligodendrocyte Apoptosis or apoptosis-like cell death, demyelination, vascular damage, neurogenic bladder, autonomic nervous disorder, sensory disturbance, dysuria, defecation dysfunction, sexual dysfunction, skin ulcer, pressure sore, palsy, Peripheral circulatory failure and the like. Presumably, ginsenoside derivatives such as dihydrozincenoside Rbi, as well as natural ginsenosides such as ginsenoside Rbi, regenerate and regenerate central nervous tissue and regenerate and remodel cerebral spinal cord blood vessels. It is thought that it exerts its effects and effects on the above-mentioned conditions, symptoms or diseases through its anti-apoptotic action.

In addition, intravenous administration of a ginsenoside derivative such as dihydrozincenoside Rb of the present invention shows a novel effect of regenerating and reconstructing a blood vessel or a nerve tissue. Diseases that cause alterations, damage to blood vessels, or diseases or conditions that are primarily caused by impaired blood flow (e.g., transient cerebral ischemia, aortitis syndrome, diabetes, cancer, malignancy, sarcoma, Malignant neoplasm, heart failure, cardiomyopathy, acute peripheral arterial occlusion, DIC, thrombosis, thrombophlebitis, collagen disease, cerebrovascular disease, cerebral bleeding, subarachnoid hemorrhage, cerebral infarction, atherosclerosis, peripheral Circulatory insufficiency, chills, poor blood color, physical fatigue, menopause, cyanosis, gastrointestinal weakness, anorexia, alopecia, subdural hematoma, epidural hematoma, obstructive thromboangitis, anemia, renal anemia, regeneration Aplastic anemia, Thrombocytopenic purpura, angina, myocardial infarction, vasculitis, central retinal arteriovenous obstruction, liver, kidney, heart • cerebral ischemia-reperfusion injury, thrombotic thrombocytopenic purpura, granulocytopenia , Vascular injury, Behcet's disease, diabetic neurosis, hemorrhoids, arteriosclerosis obliterans, Reino's disease, Reino's syndrome, wound, burns, frostbite, electric shock, corneal ulcer, corneal wound, laser Injury, immunity deficiency disease, AIDS, myelodysplastic syndrome, disseminated intravascular coagulation syndrome, hemorrhagic shock, radiation injury, ultraviolet radiation injury, pressure sore, skin ulcer, diabetic skin ulcer, diabetic retinopathy, Allergic diseases such as diabetic nephropathy, anaphylactic shock, Alzheimer's disease, Pick's disease, spinocerebellar degeneration, Parkinson's disease, demyelinating disease, chorea, polyglutamine disease, cerebral palsy, muscular atrophy Sclerosis, glaucoma, senile macular degeneration, AIDS encephalopathy, encephalitis, multiple sclerosis, diabetic neuropathy, retinal detachment, retinitis pigmentosa, blood diseases such as anemia, blood-forming organ diseases, bone and cartilage diseases such as fractures, carbon monoxide poisoning, neonatal asphyxia, autonomy Renal diseases such as neuropathy, peripheral neuropathy, purpura nephritis, peripheral neuropathy, hypoxic encephalopathy, Guillain-Barre syndrome, pulmonary embolism and other respiratory diseases, spastic paraplegia, progressive supranuclear palsy, spinal vascular Disorders, cardiovascular diseases such as myocardial infarction, mitochondrial encephalomyopathy, meningitis, metabolism such as diabetes, endocrine diseases, fractures, osteoporosis, spinal (lumbar) vertebral hernia, cerebral nerve diseases such as stroke, spinal canal stenosis , Spinal isolation, gastrointestinal disorders such as ischemic enteritis, slip, renal disease, compression and paralysis of the spinal cord and nerve roots associated with ossification of the posterior longitudinal ligament, and facial palsy. You. Of course, in diseases that cause histopathological changes in these blood vessels and nerve tissues, and in diseases with blood flow disorder as the main symptom, it is also possible to inhibit cell death in tissues exposed to blood flow disorder. It is a memorable effect of ginsenoside derivatives such as b. Therefore, it is considered that ginsenoside derivatives such as dihydrozincenoside Rbt reduce tissue cell damage in peripheral blood flow disorders, injuries, trauma or wounds through at least two mechanisms of action. Natural ginsenosides such as ginsenoside Rbi can also be used as a pharmaceutical composition for preventing, treating or treating the above-mentioned diseases and conditions.

Jihi Drosin Senoside R b! As can be easily inferred from the above-mentioned spinal cord injury experiment results, a pharmaceutical composition comprising a ginsenoside derivative, such as ginsenoside derivative, suppresses secondary nerve lesions and secondary lesions in a region of the brain having synaptic communication, so Degenerative disease, peripheral neuropathy, demyelinating disease, inflammatory brain neurological disease, toxic brain neurological disease, cerebrospinal vascular disease (e.g. Alzheimer's disease, Pick's disease, progressive supranuclear palsy, spinocerebellar degeneration, Parkinson's disease, chorea, polyglutamine disease, carbon monoxide poisoning, cerebral palsy, neonatal asphyxia, hypoxic encephalopathy, AIDS encephalopathy, encephalitis, acute sporadic encephalomyelitis, acute cerebellar encephalitis, transverse myelitis, amyotrophic side It is also effective for secondary lesions such as chordosis sclerosis and multiple sclerosis, and slows the progression of higher nervous dysfunction due to these diseases. of Life) can be increased. Specific examples of these brain neurological diseases include those described in a compendium (Handbook of Neurology, Differential Diagnosis and Treatment, Second Edition, Edited by Mikuni Mikuni, Medical Shoin 1999). Of course, P As described in CT / JP 0 0 Z 0 410 102 (a brain cell or ginseng protective agent consisting of ginseng), these brain-neurotic diseases are mediated through an apoptotic-like nerve cell death inhibitory effect. It is thought that ginsenoside derivatives such as dihydroginsenoside Rbt also exert an effect on lesions.

 Also, as described above, intravenous administration of a ginsenoside derivative such as dihydrozincenoside Rbi of the present invention is considered to significantly improve paralysis in spinal cord-injured animals. As is well known, nervous tissue is the most vulnerable to trauma compared to other peripheral tissues, so dihydrozincenoside R b! Pharmaceutical compositions consisting of ginsenoside derivatives such as dihydrozinoseside Rbi indicate that pharmaceutical compositions comprising ginsenoside derivatives such as dihydrozinoseside Rbi are injured in peripheral tissues other than central nervous tissue. It is also effective on wounds (including burns, frostbite, electrolysis, radiation damage, laser damage, ultraviolet light damage, and internal organ damage). Of course, these peripheral tissue traumas are also included in diseases and conditions that cause impaired blood flow.

Next, the present inventors investigated whether ginsenoside derivatives such as dihydrozincenoside Rt also have an effect on peripheral tissue diseases that cause impaired blood flow due to disruption or cutting of blood vessels. Examined. For this reason, wounds, particularly open wounds, were selected as diseases in which blood vessels were ruptured or severed, and the therapeutic effect of dihydrozincenoside Rbi on open wounds was examined. Under inhaled anesthesia, 6 mm diameter punch biopsies were applied to the back of the rat (n = 4) at five locations to create open wounds. This causes the blood vessels in the area to be cut instantaneously, causing blood flow obstruction in the open wound. Thereafter, each open wounds, dihydric Doroji Nsenosai de R bi, respectively 0.0 0 0 1 wt% (1 0 ^4% by weight), 0.0 0 0 0 1 wt% (I t) - ⁵ wt%) , 0.0 0 0 0 0 1 wt% (1 0 ⁶ wt%), 0.0 0 0 0 0 0 1 wt% (1 ^0-7 wt%), Purobe bets (ophthalmic containing a concentration of White petrolatum) was applied once a day 0.1 g for 9 days. Only the same amount of the plot was externally applied to the control. Immediately after the animal was euthanized by anesthesia, the wound skin was collected and photographed. The collected skin tissue was stored in a fixative. The results are shown in FIG. Figure 9 is a photograph replacing the drawing. In FIG. 9, four examples are shown, and a first example, a second example, a third example, and a fourth example are shown from above. There are open wound marks at 5 places, 2 on the left and 3 on the right, each on the left From 1 0 ^4% by weight, 1 case of 0 one ⁵ wt%, 1 0 one ⁶ wt% of the cases from the top of the right side, in the case of 1 ^0-7 wt%, in the case of 0% (Control ).

Mercy Dorojinsenosai de R bi of 0.0 0 0 0 1 wt% (1 0 ⁵ wt%) from 0.0 0 0 0 0 0 1 wt% as shown in FIG. 9 (1 ^0-7 wt%) It is clear that topical application of a prote containing (i.e., dihydrozincenoside Rb! At a concentration of 100 ng Zg to lng / g) to open wounds clearly shows that Wound healing was promoted. In the case of topical administration of a low concentration of dihydrozine cenoside Rbi, clear hair growth was observed in the wound healing area. Therefore, when a ginsenoside derivative such as dihydroginsenoside Rbi is used as an external preparation for skin, the concentration of the composition in the external preparation is 0.01% by weight or less, preferably less than 0.01% by weight. 0 0 0 1 wt% or less, more preferably 0. 0 0 0 0 0 0 1 wt% (1 ^0-7 wt%) were considered to be preferable to set the longitudinal or less. Therefore, for the prevention, treatment or treatment of diseases or conditions that cause impaired blood flow (for example, wounds, burns, pressure sores, skin ulcers, hemorrhoids, etc.), it consists of ginsenoside derivatives such as dihydroginsenoside R bi. When the pharmaceutical composition is administered topically or topically, its concentration in the external preparation for skin or the topical preparation (including external preparation for mucosa and suppository) is less than or equal to 0.001% by weight, preferably less than 0.01% by weight. It is preferably set to not more than 0.001% by weight (100 to ¹⁵ % by weight), more preferably not more than 0.001% by weight (10 to ⁷ % by weight). The upper limit of the concentration of ginsenoside derivatives in external skin preparations and topical administration (including external mucosal preparations and suppositories) for the prevention, treatment or treatment of the above-mentioned diseases is 5% by weight or less, preferably 1% by weight or less. And more preferably 0.1% by weight or less.

In the experimental example described above, Ri bets in the denominator the area of open wound that topical application of Purobetonomi, 0.0 0 0 1% by weight (1 0 ^4% by weight) 0.0 0 0 0 0 0 1 The area of the open wound to which topical application of 10% by weight (10 to ¹⁷ % by weight) of dihydrozine senoside Rbi was applied to the molecule was calculated, and the ratio was calculated. The results are shown in FIG. In FIG. 10, * indicates that there is a significant difference between P and 0.05 when n = 4. The test is based on Fisher's PLSD.

As shown in the first 0 figure 0.0 0 0 0 1 wt% (1 0 ⁵ wt%) of the following concentration The topical application of dihydrozincenoside Rb to open wounds promoted regeneration and remodeling of skin tissues, especially blood vessels in the skin, and improved impaired blood flow. As a result, wound healing was significantly promoted. Especially 0.0 0 0 0 1 wt% (1 0 ⁵ wt%) of the following dihydric Dorojinseno rhino de R b ie 1 0 O ng / g or less or 1 0 O ng Zm l following dihydric de Rojinsenosai de R bi The fact that topical administration significantly reduced open wounds is due to the fact that ginsenoside derivatives such as dihydrozincenoside Rb have an extracellular fluid concentration of the affected tissue of less than 100 ^ g / m1, preferably 100 ng / m 1 or less, more preferably 1 ng / m 1 or less, and still more preferably 0.0000. At OOOO fg / m 1, it strongly supports the rapid promotion of wound healing by remarkably promoting the neovascularization, regeneration or remodeling of blood vessels. In the early stage of wound healing, vascular endothelial cells, epithelial cells, epidermal keratinocytes, vascular smooth muscle cells, stem cells, fibroblasts, etc. were active as described in PCT / JP 00/055554. When the wound is healed, these new blood vessels or regenerated blood vessels will regress or disappear from the excessive ones. This phenomenon is referred to as blood vessel reconstruction in the present specification and PCT / JP 00/05554. In other words, the regenerative and remodeling phenomena of all living tissues require the opposing events of cell division, proliferation, migration, differentiation, adhesion, and mitotic arrest to occur in an orderly manner. The pharmaceutical compositions of the present invention are believed to be able to accomplish these complex events reliably and quickly.

 In addition, ginsenoside derivatives such as dihydroginsenoside Rbi may be useful for the prevention, treatment, and treatment of malignant neoplasms (including cancer and sarcoma), if the action of promoting the remodeling of blood vessels is selectively exerted. . Of course, natural ginsenosides such as ginsenoside Rbi have similar effects, efficacy and uses.

From the above experimental results, application of low-concentration ginsenoside derivatives, especially dihydrozinosenoside; b, for external application to the skin not only promotes regeneration and reconstruction of cut blood vessels, but also epidermal tissue of the skin and dermis It is thought to promote regeneration and remodeling of connective tissue, dermal papillae, sebaceous glands, nerves, sweat glands, dermal papilla, pilo muscularis, hair follicles, etc., and hasten wound treatment. As far as the inventor knows, the effect of topical administration of dihydrozincenoside Rbi at a low concentration is far greater than that of peptidic factors (PDGF, EGF, bFGF). Is excellent. Ointment or external preparation you containing low concentrations of dihydric Dorojinsenosai de R bi used in this experiment, similarly to the ointment or external preparation containing Jinsenosai de R b _t, wound not skin only, damage or blood flow Any organ or tissue that has caused damage or histopathological changes (cornea, oral mucosa, outer ear, gastrointestinal mucosa, nasal mucosa, eardrum, vagina, bladder, uterus, urethra, airway mucosa, rectum, rectal mucosa, anus, etc. ) Can promote the regeneration and reconstruction of vascular and other diseased tissues. In particular, suppositories containing ginsenosides at low concentrations (less than 0.001% by weight or less than 0.002% by weight) may be used for the prevention, treatment or treatment of hemorrhoids. Or, if applied externally to the rectum (mucosa), excellent effects can be obtained. From the results of this experiment, it was found that the amount of ginsenoside derivatives, especially dihydrogin genoside Rbi, per 10 g of the probe was 0.1 mg or less, and preferably 0.001 mg or less. . That is, the optimal skin external dose of ginsenoside derivatives, particularly dihydrozinsenoside Rbi, to humans or vertebrates having skin diseases is quite small. When ginsenoside derivatives such as dihydrozincenoside Rbi are mixed per 10 g of the protolyte for the purpose of prevention, treatment or treatment of the above-mentioned disease, the upper limit is 1 g or less, preferably 0.1 g or less, Preferably it is less than 0.000 lg. Concentrations when natural ginsenosides such as ginsenoside Rb are used as an external preparation for skin and a mucosal preparation are described in PCT / JP00 / 0555554.

As mentioned above, external application of ginsenoside derivatives such as dihydrozincenoside Rbi to the skin promotes regeneration and reconstruction of cut blood vessels, as well as epidermal tissues of the skin, connective tissues of the dermis, papillae of the dermis, and subcutaneous The fact that tissue, blood vessels, pilates, sebaceous glands, sweat glands, dermal papilla, hair follicles, etc. are promoted to be regenerated and reconstructed is, of course, the topical application of ginsenoside derivatives such as dihydrozine senoside R bi to skin. , Vascular intima, vascular media, vascular adventitia as well as epidermal cells, epidermal keratinocytes, Merkel cells, melanosite, Langerhans cells, keratinocytes, fibroblasts, vascular endothelial cells, vascular smooth muscle cells, Clearly promotes regeneration and remodeling of sebaceous gland cells, adipocytes, sweat gland cells, hair follicle cells, pilus muscle cells, mesenchymal cells, skin stem cells, etc. To have. Such low doses of ginsenoside derivatives such as dihydrozincenoside Rb are simple. Achieving blood vessel and skin tissue regeneration / reconstruction or wound healing in a vivid way alone means that cytokines involved in blood vessel regeneration / reconstruction and skin tissue wound healing / regeneration / reconstruction Growth factors or growth factors and their receptors and transcription factors (eg, EGF, TGF-j31, SCF, TGF-a, FGF, VEGF, angiopoietin, Tie_l, Tie — 2, ephrin— B2, Eph4B, CXCR4, PDGF_BB, TGF—] 31, PDGF-AB, IGF, She, SCL, ets—10, NDF, transcription Factor HIF-1, FKB, VEGFR, transcription factor STATs, EGFR, HGFR, TGFR, IGFR, KGF, HGF, erythropoietin, PDGF, PDGFR, TGF—32 , TGF-03, FGF-2, U-PA, t-PA, etc.) and low-dose ginsenoside derivatives, especially dihydrozincenoside, in the function of blood cell components and plasma components. It indicates that it is regulated by R b. In other words, a review by Singer et al. (Singer, AJ, CIark, RAF, New Engl. J. Med., 341, 738-746, 1999) and experimental medicine (Vol. 17, No. 6, Planning, Masashi Shibuya, 1999, By modulating the molecular groups described in (Yodosha), it is possible to induce low-dose, low-concentration ginsenosides in complex life phenomena related to wound healing or tissue regeneration, remodeling and vascular regeneration and remodeling. It can be said that the conductor, especially the dihydrozine senoside R bi, was achieved by itself. For example, vascular regeneration and remodeling phenomena can be achieved by dividing, proliferating, migrating, migrating, differentiating, adhering, and forming lumens of vascular endothelial cells, regenerating and remodeling extracellular matrix, intima, Complicated processes such as regeneration and reconstruction of the basal, medial, adventitia, and autonomic nerves must be performed, but ginsenoside derivatives such as dihydroginsenoside Rb cause these vital phenomena. It is thought that it can be adjusted systematically. That is, it is considered that ginsenoside derivatives such as dihydrozincenoside Rbt promote regeneration and reconstruction of all cells constituting blood vessels and skin tissues and secretions thereof. Therefore, ginsenoside derivatives such as dihydroginsenoside Rbi are useful for treating biological tissue, especially blood vessel or skin tissue, against organic diseases that cause histopathological changes in living tissues such as skin and diseases that cause impaired blood flow. It can be said that it exerts its effects and effects through the action of promoting regeneration and reconstruction. The diseases that cause such impaired blood flow of the skin or histopathological changes include the following. That is, skin tissue wounds, burns, Radiation damage, frostbite, UV damage, electric shock, trauma, skin ulcers, pressure sores, various wounds after surgery, electrolysis, laser damage, contact dermatitis, vesicular dermatitis, atopic dermatitis , Depressive dermatitis, xeroderma, sebum deficiency, diabetic skin ulcer, self-sensitizing dermatitis, erythroderma, exfoliative dermatitis, epidermolysis bullosa, photosensitivity, chronic purple purpura (Schamber's disease) ), Steven Johnson syndrome, stroflus, hay fever, insect bites, prurigo, erythema multiforme erythema, annular erythema, erythema nodosum, pemphigus, pemphigoid, herpetic dermatitis, palm躕 Pustulosis, psoriasis, lichen planus, ichthyosis, lichen follicularis, xanthomatosis, cutaneous amyloidosis, herpes simplex, viral warts, infectious molluscum, pyoderma, cutaneous tuberculosis, non-skin Typical mycobacteriosis, ringworm, skin , Oral candidiasis, scabies, hair loss, syphilis, keloids, hypertrophic scars, hemangiomas, lymphomas, nevus, vitiligo vulgaris, sparrow eggs, melasma, melasma, sweat blisters, acne, acne , Rosacea skin, rosacea skin-like dermatitis, oral mucosa damage, stomatitis, mouth dermatitis, skin aging symptoms

(E.g., skin atrophy, susceptibility to infection, sagging, dandruff, alopecia, gray hair, itching, shavings, sebum deficiency, stratum corneum detachment, keratinocyte detachment, cracks, cracks, irritations, spots, sunburn, wrinkles, freckles , Poor reproduction, pigmentation, dryness, etc.), alopecia, peritonitis, ingrown nails and the like. As described in PC TZ JP 0 0 Z 0 104 0 2 and PC TZ JP 0 0/0 55 54, ginsenoside derivatives such as dihydrozincenoside Rb are particularly suitable for ginsenosides. Since it exhibits effects very similar to ginsenoside Rbi, efficacy, use, and pharmacological action, naturally, natural ginsenosides such as ginsenoside Rbi or natural products containing ginsenoside Rbi are used in the present invention. It may be used instead of a pharmaceutical composition (ie, a ginsenoside derivative such as dihydrozincenoside R b). A natural ginsenoside such as ginsenoside R b, or a natural product containing ginsenoside R bt or an extract thereof is used as a pharmaceutical composition for preventing, treating or treating diseases or conditions that cause impaired blood flow. When topical administration is performed, for example, the concentration is preferably set to less than 0.001% by weight. However, when ginsenosides such as ginsenoside Rb and other pharmaceutical compositions are used together (mixed), the concentration of ginsenosides such as ginsenoside Rbi is less than 0.0002% by weight. It is preferable to set Of course, the concentration of ginsenoside derivatives such as dihydrozincenoside Rb is also 0. It may be set to less than 0.002% by weight. Natural ginsenoside compounds such as ginsenoside Rt or ginsenosides have an extracellular fluid concentration of 10 ng / m1 (about 9 nM) or less, preferably lng / ml (about 0.9 n M) Below, more preferably from 0.01 to 100 fg / ml or from 1 to L: 0.000 fg / ml to promote regeneration and reconstruction of blood vessels. Of course, ginsenoside R b! It is said that natural ginsenosides such as and the like promote the regeneration and remodeling of tissues such as blood vessels by increasing, decreasing or regulating the molecular groups involved in tissue regeneration and remodeling as described above.

 As described above, the pharmaceutical composition of the present invention is considered to prevent, treat, or treat a disease or condition causing blood flow disorder through an anti-apoptosis effect and a blood vessel regeneration / remodeling promotion effect. Therefore, the present inventors next investigated whether ginsenoside derivatives such as dihydrozinosenoside Rb regulate the expression of major factors (groups of molecules) involved in cell apoptosis or vascular regeneration / remodeling. Was. Therefore, Be 1 — X and caspase 3 are typical molecules involved in apoptosis or apoptosis-like cell death, and VEGF is a typical molecule involved in revascularization and Z or remodeling. We examined whether the expression of these molecules was altered by dihydrozincenoside Rbi.

 Experimental techniques are described in the papers published by the present inventors (Sakanaka, Tanaka) (Wen, TC. Et al., J. Ex. Med., 188, 635-649, 1998) and the papers of Toneguchi et al. , FEBS Leiters, 442, 167-172, 1999). The cerebral cortical neurons isolated from the embryonic day 17 rat were cultured in a medium containing 10% fetal calf serum. On day 2 of the culture, the medium was replaced with a serum-free medium. On day 3 of the culture, dihydroginsenoside Rbi was added at a concentration of 0, 1, 100 μg / m 1, and the cells were cultured for 6 hours. Thereafter, total RNA was extracted from the cultured neurons. After DNase treatment, cDNA was prepared from total RNA using oligo dT primer and reverse transcriptase. The PCR reaction was performed using Taq [polymerase]. The PCR-primers and PCR reaction conditions used are as follows. I3-actin is an internal standard.

 The PCR product generated after development was electrophoresed on a 3% agarose gel and visualized by ethidium bromide staining. The results are shown in FIG. 11 and FIG. Figures 11 and 12 are photographs replacing the drawings.

As shown in FIG. 11, compared to the neurons without dihydrozincenoside Rbi, B e 1— VEG FmRNA expression was enhanced. In particular, the strongest expression of VEGF mRNA was observed in the group to which lf gZml was added. In addition, the VEGF of the rat is divided into three subtypes, VEGF120, VEGF164, and VEGF188, corresponding to the number of constituent amino acids. At least two are allowed as shown in the figure. In addition, as shown in Fig. 12, dihydrogin genoside Rb 丄 The expression of caspase-3 mRNA was suppressed in neurons added at a concentration of 1,100 fg / 1. In particular, the strongest suppression of caspase 3 mRNA expression was observed in the 1 fg / m 1 addition group.

 Based on the above, ginsenoside derivatives, especially dihydrozincenoside Rbi, are books such as Be1 — or caspase 3 (Experimental Medicine, Vol. 17, No. 13, Planning, Shigeichi Nagata, 1999, Yodo It can be said that apoptosis or apoptosis-like cell death is inhibited by increasing, decreasing, or regulating the expression of the apoptosis-related molecules described in Jpn. Ginsenoside derivatives, especially dihydroginsenoside Rbi, are described in VEGF and other books (Experimental Medicine, Vol. 17, No. 6, Planning, Masashi Shibuya, 1999, Yodosha). It is thought that increasing, decreasing or regulating the expression of the assembly-related molecules promotes the regeneration and remodeling of blood vessels.

 That is, a pharmaceutical composition comprising a ginsenoside derivative such as dihydrozincenoside Rb can promote apoptosis or apoptosis through promotion of Be1-X expression and / or suppression of caspase-3 expression. It is used for the prevention, treatment, and treatment of diseases (including pathological conditions) that inhibit cis-like cell death and cause cell death. Of course, ginsenoside derivatives such as dihydro ginsenoside R bi may also enhance, attenuate or regulate the action of Bel — and / or caspase 3 transcription factors (eg, NFκB, STATs, etc.). . Diseases that cause cell death, for which the pharmaceutical composition of the present invention is expected to be applied, are described in PCTZ J P 00/04102. In addition, since the pharmaceutical composition of the present invention also has an action of promoting the regeneration and remodeling of blood vessels in addition to the above-described anti-apoptotic action, diseases and conditions that cause impaired blood flow through these two actions. It is useful for prevention, treatment, or treatment of Diseases and conditions that cause impaired blood flow have already been described herein. Natural ginsenosides such as ginsenoside Rbi are also considered to promote Be1— expression and VEGF expression and suppress caspase-3 expression.

 In the following, ginsenoside derivatives other than dihydroginsenoside Rbi will be briefly described by taking the ginsenoside Rb derivative in Fig. 13 as an example.

(1) at the upper left of FIG. 13 is an example of a derivative in which a hydroxyl group is acylated or acetylated. In addition, a double bond in a side chain may be reduced. (2) is an acylation or case This is an example in which a double bond in the side chain is converted to a single bond and an arbitrary functional group (for example, one or more hydroxyl groups) is bonded to the same part in addition to the chilling. It is also possible to convert. (3) in FIG. 13 is an example of a derivative in which the terminal is converted to an aldehyde group by cleaving the double bond in the side chain in addition to acylation or acetylation.

 (4) is an example in which an arbitrary functional group such as an alkyl group or a aryl group is bonded to the end of the side chain in addition to the acylation or acetylation, and (5) is an example in which the side chain is added in addition to the acylation or acetylation. (6) is an example in which the double bond in the side chain is epoxidized in addition to acylation or acetylation,

 (7) is an example in which a double bond in a side chain is cleaved to bond an arbitrary functional group, for example, a propyloxyl group, and an aldehyde group may be bonded instead of a lipoxyl group.

 (8) is obtained by substituting one methyl group at the terminal of the side chain with a hydrogen atom and substituting the other methyl group with an arbitrary functional group such as an alkyl group or a peryl group. This is an example in which a heavy bond is converted to a single bond, and an arbitrary functional group, for example, one or more hydroxyl groups is bonded to the same portion. As shown in the figure, a dihydroxy cinnoside R in which two hydroxyl groups are bonded is shown. bt. In this case, only one hydroxyl group may be replaced with any hydrogen atom to create monohydroxyzine cenoside R t. Fig. 13

(10) is an example in which two molecules of the hydroxyl group described in (9) are dehydrated and epoxidized, that is, epoxyzine cenoside Rbi. Further, (11) protopanaxadiol. Any compound having protopanaxatriol, damarane or a reduced form thereof as a basic skeleton is included in the category of ginsenoside R t derivative. In this

In addition, ginseng contains about 30 types of purified saponins, that is, natural ginsenosides or ginsenoside compounds in addition to ginsenoside Rbt (Junsho Shoji, Ginseng '95, PP251-26K edited by Akira Kumagai, Kyoritsu Publishing Co., Ltd.), and the chemical structure of these purified saponins, that is, ginsenosides, is similar to that of ginsenoside Rbi. As a pharmaceutical composition for preventing, treating, or treating diseases that cause blood flow disorders, or as an agent for promoting revascularization and reconstruction. Can get. Of course, the novel chemical derivatives that can be prepared by using ginsenoside Rbi as a lead compound are not limited to those described above. In addition, purified saponins other than ginsenoside Rbi, that is, natural ginsenosides (especially, protopanaxadiol and protopanaxatriol), reduce the side chain of the tamaran skeleton (steroid-like skeleton) or reduce the primary chain. Chemical derivatives can be prepared in the same manner as in FIG. The chemical derivatives of oranolic acid, including ginsenoside Ro, have already been described. Naturally, the above-mentioned ginsenoside derivatives are described in PCT / JP00Z04201, PCT / JP0505505554, and Japanese Patent Application No. 2000-0-4002. Ginsenoside R b! Described in No. 03, Japanese Patent Application No. 2 0 0 1—3 7 4 5 09 and Japanese Patent Application No. 2 0 0 1 — 0 4 9 3 6 8 Or, it is said that it has all the effects, effects, and uses of dihydrozine senoside Rbi.

You next, by Jinsenosai de such as Jinsenosai de R bt (including Jinsenosa Lee earth derivatives) are allowed to activate any transcription factor, cell death suppressing gene B c 1 - Expression of X _L We examined whether it would induce. Therefore, as a preliminary experiment, we first selected ginsenoside Rt ^ as a representative of ginsenosides, and examined whether ginsenoside Rbi increased the expression of the Bc1-X gene in neurons. Examined. The chemical structure of ginsenoside Rbi is described in PC TZ JP 00/04102 and the present specification. The experimental procedure was based on the paper by the present inventors (Sakanaka, Tanaka) (Wen T.-C., et al., J. Exp. Med., 188, 635-649, 1998). Pretreated for 24 hours with ginsenoside R b of 0 fg / m 1, 1 f / m 1, 100 f gZm l and 100 0 0 0 f gZm 1 (100 pg / m 1) Total RNA was extracted from the cultured neurons. From 3 g of the DNase-treated total RNA, cDNA was produced using oUgo dT primer and reverse transcriptase (Moloney murine leukemia virus reverse transcriptase). The gene amplification reaction (PCR) was performed using Taq polymerase under the following conditions. (1) 94: 2 minutes (2) 94 ° C., 1.5 minutes; 55 ° (: 1.5 minutes; 72 ° (: 2 minutes, 1 cycle; Bel — 25 cycles for XiJ, 20 cycles for j3-actin, and (3) 72 ° C for 2 minutes. PCR products were run on a 3% agarose gel and visualized by ethidium bromide staining. The expression of actin mRNA was used as an internal standard. The results are shown in FIG. Figure 14 is a photograph replacing the drawing.

 In addition, in order to examine whether ginsenoside Rbi enhances the expression of Be 1 — protein in neurons, a western blotting method was performed using an anti-Be 1 — protein antibody. After culturing rat cerebral cortical neurons for 48 hours in the presence or absence of ginsenoside Rbi, the cells were lysed with a sample buffer for electrophoresis and subjected to electrophoresis. Thereafter, the electrophoretic proteins were transferred to a two-nitrocellulose membrane and subjected to Western plotting. The results are shown in FIG. Figure 15 is a photograph replacing the drawing.

Further, the band reacting with the anti-Bc1— _xL protein antibody was quantified by an image analyzer. The results are shown in FIG.

 As shown in Fig. 14, in cultured neurons treated with 1 fg / m1 or 100 fg / m1 ginsenoside Rbi, the expression of Be1— mRNA was controlled. It was increasing compared to. On the other hand, ginsenoside Rbi significantly increased neuronal Bc1-X expression by about 50% in the optimal concentration range of l to 100 fgm1 (Fig. 15, Fig. 15). 16 Figure).

Next, the present inventors examined what ginsenoside R b promotes Bel-XL expression through what transcription factor. For this reason, the following experiment was performed using an astrocyte, where gene transfer was relatively easy. First, Bel—X Promo Yuichi Z Luciferase Plasmid was created. That is, using DNA extracted from tail tissue of C57BL / 6 mouse as type I, the following primers LF1, Primer LR1 and Pyrobest DNA polymerase (pyrobest DNA polymerase) (Takara) were used. 30 cycles of the PCR reaction were performed. The reaction solution was purified using QiaExII Gel Extraction Kit (Qiagen), digested with restriction enzymes XliOI and HindIII, and electrophoresed on a 2% agarose gel. A 0 bp DNA fragment was cut out. From the obtained gel slice, a DNA fragment was extracted using a QiaExII gel extraction kit (QiaExII Gel exraction kit) and inserted into pGL-2 Basic vector (Promega) (Bexx). promoter L) (Fig. 17). Similarly, using mouse MA as type II, 15 cycles of PCR reaction were performed using primer RF1 and primer RR1. Dilute the reaction solution 100-fold (Solution A), use it as type II, perform a 30-cycle PCR reaction with Primer-RF2 and Primer-RR2, digest with Sacl and BamHI, The pGL- 2 Basic vector was inserted into the SacI / BgIII site (Belt x promoter R) (Fig. 17).

 Further, the solution A was used as type III, and a PCR reaction of 30 cycles was performed using each of the primer R F1 and the primer Mut-R, the primer Mut-F, and the primer R R1. After electrophoresis on a 2% agarose gel, DNA fragments of 312 bp and 309 bp were cut out, and a DNA fragment was extracted using a QiaExII gel extraction kit (QiaExII Gel exraction kit). After mixing the extracted DNA fragments at a weight ratio of 1: 1, the mixture is used as a 铸 -type and subjected to a PCR reaction of 30 cycles with a primer RF2 and a primer RR2, and then eliminated with Sacl and BamHI. And inserted into the SacI / BgIII site of the pGL-2 Basic vector (Bcl-x promoter R (mutation) (Fig. 17)).

The primary culture of the astrocytes was performed as follows.

Astrocytes were isolated from a Wistar rat immediately after birth by a known method, cultured in a culture flask, and replanted two weeks later in a 12-well plate (12-well plate). The astrocyte was published by the present inventors (Sakanaka, Tanaka) (Fujita, H. et al., Glia, 18, 269-281, 1996; Tanaka, J. et al.). , Gl ia, 20, 23-37, 1997; Tanaka, J. et al., Glia, 24, 198-215, 1998).

The gene transfer and luciferase atsey were performed as follows.

 Transfection was performed for 5 hours in the presence of 10% FCS (fetal calf serum) using Lipofectamine (Invitrogen). Thereafter, the medium was replaced with a fresh medium, and the cells were cultured at 37 ° C. The next morning, 100 fg / ml of ginsenoside Rbi was added, and the cells were cultured at 37 ° C for 24 hours. After washing the cell surface twice with PBS, the cells were lysed with Luciierase Cell Culture Lysis eagent (Promega) 1001. The amount of luciferase in the solution was measured using a Luciferase Assaay System (Promega) and a luminescence sensor JNR (ATTO).

The results are shown in FIG. As shown in the first and second columns from the left in FIG. 18, control of ginsenoside Rbi to astrocytes transfected with 1 L of Be1_x promoter was not performed. No change was observed in luciferase activity as compared with ginsenoside Rb non-administered cases. On the other hand, as shown in the third and fourth columns from the left in FIG. 18, when ginsenoside R b was administered to an astrocyte transfected with Be 1 —X promoter R, control was obtained. The luciferase activity was significantly increased as compared with (ginsenoside Rbt non-administration example). As shown in FIG. 17, a sequence similar to the STAT5 binding sequence exists in the Be1—X promoter R, but no such sequence exists in the Be1—X promoter-L. Thus, the ginsenoside R bi increases the activity of luciferase, a repo overnight gene, through the activation of the transcription factor STAT5 located upstream of Exon 2 (Ex on 2) of the Bel-X gene. It was considered. On the other hand, as shown in the fifth and sixth columns from the left in FIG. 18, the mutant (with mutation) STAT 5, that is, B c 1 containing STAT 5 m, x promoter-R (mutation) (mutation) When ginsenoside Rb: was administered after transfection of astrocytes to astrocytes, no change was observed in luciferase activity as compared to the control (ginsenoside Rbi-untreated example). (Fig. 18). ** in FIG. 18 indicates P <0.01, and the statistical analysis method is based on the Studentt test. Based on the above, ginsenoside R b! Is activated through the activation of transcription factor STAT5, which has a binding site upstream of Exon 2 (Exon 2) of the Be1-X gene (Fig. 17). It can be said that it up-regulates the production of luciferase, a repo overnight gene (Fig. 18). In this experiment, we performed promoter attestation by replacing Be1—XL with a repo-easy-to-measure repo—Yuichi Gene (Luciferase), but in actual cells, ginsenoside R bi In this experiment, it was revealed that the expression of the Be1-XL gene was promoted through activation of the factor STAT5. Presumably, ginsenosides such as ginsenoside Rb also increase the enzymatic activity of JAK2, phosphorylate STAT5, and promote nuclear translocation if phosphorylated STAT5 homodimer forms. it is conceivable that. As a result, STAT5 is thought to function as a transcription factor.

 Now, after an overview of STAT5, the significance of ginsenosides in activating STAT5 will be described. So far, about six types of transcription factors called STAT (signal transducer and activator of transcription) have been discovered as intracellular signaling molecules of cytokine signals. Among them, STAT 5. Interleukin 2 (IL-2), Interleukin 3 (IL-3), Inuichi Leukin 5 (1 L-5), Interleukin 7 (IL-7), Interleukin 9 (IL-9), interleukin 15 (IL-15), granulocyte 'macrophage' colony stimulating factor (GM-CSF)> growth hormone, tgrowth hormone, GH ), Prolactin, erythropoietin (EPO), etc., are activated by stimulation of site hormones and hormones, and are activated by Bel-X (including Bcl-xs, Bet-xj3), / 3-force zine, It is known to up-regulate the transcription of Oncos-Mintin M etc. Therefore, if a pharmaceutical composition such as ginsenosides that activates the transcription factor STAT5 is found, the pharmaceutical composition exerts the same physiological actions, effects, and potencies as the above-mentioned cytokine hormone, Moreover, it can be said that the expression of B c 1 —x, —casein, oncostatin Μ, etc. is also induced.

Among the above-mentioned sites and hormones, IL_2 promotes 促進 cell proliferation, induces natural killer (ΝΚ) cells, cytotoxic Τ induces cells, and activates lymphokine (lymphokine activated killer) Induction of (LAK) cells, increase of B precursor cells It has effects such as inducing proliferation and differentiation, and is currently being marketed as an anticancer agent. IL-13 promotes blood stem cell proliferative function and platelet progenitor cell proliferative function. IL-5 has effects such as induction of B cell proliferation, promotion of differentiation of B cells into antibody-producing cells, induction of eosinophil proliferation and differentiation, and induction of expression of IL-2 receptor. IL-17 has effects such as induction of proliferation and differentiation of precursor B cells, induction of proliferation and differentiation of precursor T cells, induction of LAK cells, and activation of monocytes. IL-19 promotes the proliferation of platelet progenitor cells. IL-15 promotes T cell proliferation and activates NK cells and LAK cells. IL-115 also promotes B cell proliferation and, like IL-2, can be used for site-in therapy of cancer, sarcoma, and malignant neoplasms. Erythropoietin (EPO) is used clinically as a therapeutic agent for renal anemia or secondary anemia because it differentiates and proliferates erythroid progenitor cells into erythrocytes. In addition, GM-CSF promotes the proliferation and differentiation of neutrophils, eosinophils and macrophages, and induces megakaryocyte differentiation. Useful.

 Therefore, the above-mentioned site-inducing compounds have anti-cancer effect, anti-tumor effect, cancer metastasis suppressing effect, secondary anemia treatment effect, immunodeficiency disease (including AIDS) treatment effect, renal anemia treatment effect, aplasticity It can be said to show an anemia treatment effect, a thrombocytopenia treatment effect, or a neutrophil recovery promotion effect after cancer chemotherapy.

 On the other hand, target organs for growth hormone include liver, kidney, adipocytes, muscle, lymphocyte, thymus, etc. In these organs or tissues, receptors for growth hormone are expressed. Growth hormone has a growth promoting effect by stimulating the production and secretion of insulin-like growth factor (IGF-1, somatomedin C) in the liver, muscle and kidney. More specifically, growth hormone promotes the proliferation of chondrocytes, the synthesis of chondroitin sulfate, the hypertrophy of cells such as hepatocytes, and the assimilation of proteins. Therefore, growth hormone can also be used as a composition for regulating the growth of animals and plants, and as a pharmaceutical composition for inhibiting aging and degeneration of cartilage.

Target organs of prolactin include mammary gland, liver, kidney, adrenal gland, ovary, prostate, seminal vesicle, thymus, bladder, etc. In these organs or tissues, prolactin receptors are expressed. Prolactin has a wide variety of physiological effects in a wide range of animals, including the promotion of mammary gland development, the promotion of casein synthesis, the stimulation of lactation, and the promotion of prostate and seminal vesicle gland development. Therefore, Prolactin is thought to be useful in the prevention, treatment, and treatment of diseases, conditions or disorders that exhibit insufficient lactation and poor mammary gland development. Prolactin may also be useful in preventing, treating, and treating sexual dysfunction.

 Oncostatin M promotes blood cell production and proliferation of vascular endothelial-like cells. Therefore, Oncostin M is also considered useful for the prevention, treatment or treatment of anemia, immunodeficiency disease, thrombocytopenia, granulocytopenia, leukopenia, purpura, and DIC.

 / 3 — Power zein is the major protein in milk, and its production is induced by prolactin. Therefore, β-one force zein is considered to be useful for prevention, treatment or treatment of lactation deficiency.

 In summary, the above-mentioned site force-in, hormone, oncostatin Μ or one-casein is a malignant neoplasm, cancer, sarcoma, anemia, immunodeficiency disease (including AIDS), renal anemia, secondary anemia, regeneration Aplastic anemia, hereditary spherocytosis, autoimmune hemolytic anemia, myelodysplastic syndrome, granulocytopenia, agranulocytosis, purpura, idiopathic thrombocytopenic purpura, disseminated intravascular coagulation (DIC), growth hormone deficient short stature, pituitary dwarfism, osteoarthritis of the knee, osteoarthritis of the hip, cervical spondylotic myelopathy, lumbar disc herniation, lactation deficiency or degenerative spine It is considered useful for prevention, treatment or treatment of the disease.

Therefore, ginsenosides such as ginsenoside Rbi can be converted to site force-in (IL-2, IL-3, IL-5) through the activation of the transcription factor STAT5 in all cells, especially in the mouth opening site. , IL-7, IL-9, IL-15, GM-CSF, EP0), hormones (GH, prolactin), oncoscintin M or / 3-casein It can be said that it takes over the function of the substance. More specifically, ginsenosides, such as ginsenoside Rbt, can be used to treat malignant neoplasms, cancer, sarcoma, anemia, immunodeficiency diseases (including AIDS), Anemia, secondary anemia, aplastic anemia, hereditary spherocytosis, autoimmune hemolytic anemia, myelodysplastic syndrome, granulocytopenia, agranulocytosis, purpura, idiopathic thrombocytopenic purpura Disease, thrombotic thrombocytopenic purpura, disseminated intravascular coagulation, shortage of growth hormone secretion, pituitary dwarfism, knee osteoarthritis, hip osteoarthritis, cervical spondylotic myelopathy, It is useful for the prevention, treatment or treatment of lumbar disc herniation, lactation deficiency or spondyloarthropathy. Especially the present invention The pharmaceutical composition is useful for the prevention, treatment or treatment of blood and hematopoietic organ diseases such as renal anemia and granulocytopenia or bone and cartilage diseases such as osteoarthritis of the knee.

Then, the present inventors have dihydric Dorojinsenosai de R bi is B c not only B c 1 one mRNA in neurons 1 - To examine or enhance expression of x _L anabolic, B e 1 - a x _L antibody Western blot method was performed using the method. Rat cerebral cortical neurons were cultured for 24 hours in the presence or absence of dihydrozine senoside Rbi, and the cells were lysed with a sample buffer for electrophoresis and electrophoresis was performed. Thereafter, the electrophoretic protein was transferred to a nitrocellulose membrane and subjected to Western blotting. For details of the experimental technique, see the papers published by the present inventors (Sakanaka, Tanaka) (Wen Τ ·-, et al.,

J. Exp. Med., 188, 635-649, 1998). The results are shown in FIG. 19, which is a photograph replacing the drawing.

 Furthermore, the band that reacted with the antibody after anti-Be1-X was quantified using an image analyzer. The results are shown in FIG.

 As shown in FIGS. 19 and 20, dihydrozincenoside R bi significantly increased the expression level of B e 1 -protein in neurons in the optimal concentration range of 1 to 100 fg Xm 1. Was. * In FIGS. 19 and 20 indicates P <0.05, and the statistical analysis method is based on AN OVA + Fisher's PLSD.

 From the above results, dihydrodine senoside R b! It can be said that ginsenoside derivatives, such as ginsenoside Rbi, also enhance neuronal Be1— expression. In addition, as described in PCTZ JP 00/0555554, dihydrozincenoside R bi and ginsenoside R bi have extremely similar pharmacological actions. Like ginsenoside Rbi, it is thought that the activation of transcription factor STAT5 also up-regulates the expression of Be1_χιι ^ in nerve cells.

Therefore, ginsenoside derivatives such as dihydroginsenoside Rb can be used to activate cytokines (IL-2, IL-3, IL-3) through the activation of the transcription factor STAT5 of cells such as the ostium mouth. 5, IL-7, IL-9, IL-15, GM-CSF, EP0), hormones (GH, prolactin), oncostatin M, or β-casein. It can be said that it takes over the function. More specifically, dihydrozine cenoside R bt Ginsenoside derivatives of malignant neoplasm, cancer, sarcoma, anemia, immunodeficiency disease (including AIDS), renal anemia, secondary anemia, Aplastic anemia, hereditary spherocytosis, autoimmune hemolytic anemia, myelodysplastic syndrome, granulocytopenia, agranulocytosis, purpura, idiopathic thrombocytopenic purpura, thrombotic thrombocytopenic purpura Disease, disseminated intravascular coagulation syndrome, shortage of growth hormone secretion deficiency, pituitary dwarfism, knee osteoarthritis, hip osteoarthritis, cervical spondylotic myelopathy, lumbar disc herniation, lactation Useful for the prevention, treatment or treatment of insufficiency or osteoarthritis. In particular, the pharmaceutical composition of the present invention is useful for prevention, treatment or treatment of blood-hematopoietic organ diseases such as renal anemia and granulocytopenia or osteochondral diseases such as osteoarthritis of the knee.

 By the way, the ginsenoside R b c 1-2 protein family of cell death suppressor gene products

The present inventors have already found that apoptosis or apoptosis-like cell death of a cell is strongly suppressed through an increase in the expression of B e1 — (WO0Z374781). In addition, a group of prosavosine-related peptides, which exhibit a potent anti-apoptotic action similar to ginsenoside Rbi, also exhibit Bc 1 -X expression-enhancing action, and have been tested in in vivo and in vitro experimental systems. Like ginsenoside R bt, it has been found to be useful for the prevention, treatment or treatment of cerebrovascular disorders (Japanese Patent Application No. 11-185, EP 0 03 05 05 04) No., Igase, K. et.al., J. Cereb. Blood Flow Metab., 19, 298-306, 1999, WO 0/374841, PC TZ JPOO / 04201 ). Further, it has the same action as the dihydrozine cenoside Rbife of the present invention. Based on these facts, the prosabocin-related peptides described in Japanese Patent Application No. 1 1-185510 and EP 0 305 504 are not considered as ginsenoside R bi or zihi. It is presumed that it can be used as a pharmaceutical composition for the prevention, treatment or treatment of diseases or conditions that cause impaired blood flow in the same manner as Drosin Senoside Rbi. In addition, the present inventors (Osaka and Tanaka) reported that L-serine and / or glycine were enhanced through increased expression of a cell death suppressor gene product Bc1-1w, which also belongs to the Bc1-2 protein group. It has been shown to exert an anti-apoptotic effect on force (Yang, L. et al., Eurosci. Lett., 295, 97-100, 2000). By the way, 3-1 and 8 0 1 — ^ are expressed in cells of every tissue, and the physiological functions of both gene products are very similar, Again, it can be assumed that L-serine and / or glycine can also be used as a pharmaceutical composition for preventing, treating, or treating diseases or conditions that cause impaired blood flow. In addition, the isocarbacycline group described in Japanese Patent Application No. 2000-4002639 also exhibits an anti-apoptotic effect by suppressing the expression of BaX which is one of the Be1-2 protein group. The present inventors (Sakanaka) have shown that they are useful for the prevention, treatment or treatment of cerebrovascular disorders. Therefore, it can be said that the above-mentioned isocarpacycline group can also be used as a pharmaceutical composition for preventing, treating, or treating diseases or conditions that cause impaired blood flow. Therefore, a compound that inhibits apoptosis or apoptosis-like cell death by regulating the expression of the Be1-2 protein group is a pharmaceutical composition for preventing, treating, or treating a disease or condition that simultaneously impairs blood flow. It can be used as However, it is difficult to explain the mechanism of action only from the viewpoint of regulating the expression of the Bc1-2 protein group. In other words, the present invention comprises administering a test substance to cultured cells and measuring the expression regulating action of the Be1-2 protein group, comprising preventing, treating or treating a disease or condition causing blood flow disorder. It also provides a method of searching for a pharmaceutical composition for treatment. Needless to say, the present invention relates to a disease which causes a blood flow disorder, comprising a compound having a Bc 1-2 protein group expression regulating action or a salt thereof when administered to cultured cells by the method described above. Alternatively, a pharmaceutical composition for preventing, treating or treating a disease state is provided.

 The Bel-2 protein group has an inhibitory effect on apoptosis or apoptosis-like cell death (Bel-2, Bel-X, Bel-w, Mcl-l, Bfl-l ZB od, Nr—13, BRAG-1, Boo / Diva, Galectin—3) and those that promote apoptosis or apoptotic cell death (Bax, Bak, Bel) — Xs, Bad, Bik / Nbk, Bid, Bim / Bod, Hrk / DP5, BNI PZNix, Bok / Mtd, Blk, EGL-1) Organ apoptosis proofing method; Editing, Katsunori Otsuki, Takehiko Oji, Keiichi Watanabe, Nankodo, 2000, p16-224).

Therefore, as the compounds exhibiting the expression regulating action of the Bel-2 protein group, those which promote the expression of the above-mentioned anti-apoptotic factors or the expression of the proapoptotic factors It is conceivable to suppress this. For example, B el - erythropoietin having x _L expression enhancing action, in evening Site forceins or growth factors such as 1-leukin 3 (Wen et al., J. Exp. Med. 188, 635-649, 1998; Japanese Patent Application No. 11-185185, EP No. 0 305 504) can also be used as a pharmaceutical composition for the prevention, treatment or treatment of diseases or conditions that cause impaired blood flow because they exhibit the activity of regulating the expression of the Bc1-2 protein group. . However, the compounds exhibiting the activity of regulating the expression of the Bel-2 protein group are not limited to those described above. For example, the present inventors have found that vitamin E and the like also enhance Bc1-XL expression in cells.

 Next, the present inventors investigated whether ginsenosides activate the transcription factor HIF-1 and induce VEGF expression. For this reason, the following experiment was performed using ginsenoside R bi as a representative ginsenoside of the present invention. Details of H I F-1 will be described later.

 First, the present inventors conducted an experiment by selecting astrocyte as an example of cells in order to examine whether ginsenoside Rb increases the expression of VEGF mRNA in cells.

 Astrocytes were isolated from the Wistar rat immediately after birth by a known method, cultured in a culture flask, and 12 days later, a 10 cm dish coated with poly-L-lysine was used.

(dish). Astrosites were cultured in DMEM medium containing 10% fetal calf serum (FCS). Three to four days later, the medium was replaced with a serum-free medium, ginsenoside Rb was added at a concentration of 0.1100 fg / m1, and the cells were cultured for 6 hours. The last mouth site is based on published papers by the present inventors (Sakanaka, Tanaka) (Fujita, H. et al., Glia, 18, 269-281,

1996; Tanaka, J. et al., Glia, 20, 23-37, 1997; Tanaka, J. et al., Glia,

24, 198-215, 1998). Thereafter, total RNA was extracted from the cultured astrocytes. After DNA ase treatment, cDNA was prepared from 3 g of total RNA using oligo dT primer and reverse transcriptase. The PCR reaction was carried out using Taq polymerase in accordance with the Tonenguchi article (Tonello, FEBS Letters, 442, 167-172, 1999). The PCR-primer and PCR reaction conditions used are as follows. I3-actin is an internal standard.

 The PCR product generated after the development was electrophoresed on a 3% agarose gel, and visualized by ethidium umide staining. The results are shown in FIG. Figure 21 is a photograph replacing the drawing.

 As shown in Fig. 21, as compared with ginsenoside Rb-free astrocytes, ginsenoside; bi was added at a concentration of 100 f / m1 in the astrocytes and VEGF mRNA was not added. Expression was enhanced.

 Next, the present inventors investigated whether ginsenoside Rbi also induces VEGFFMRNA expression in human skin keratinocytes. For this reason, human skin keratinocytes are cultured in a monolayer, ginsenoside Rbi is added to the culture medium at a concentration of 0 to 10 pg / ml, and after 0, 1, 3, 6, and 12 hours. Total RNA was extracted from human skin keratinocytes. Thereafter, RT-PCR was carried out at a cycle number of 27 using the primers shown below. The results are shown in FIG.

 As shown in FIG. 22, when ginsenoside Rb at a concentration of 1 fgZml to 10 pg / ml was added to cultured human skin keratinocytes, the expression of VEGF mRNA was induced within 12 hours.

Next, the present inventors examined whether ginsenoside Rb increased VEGF protein expression. For this purpose, human skin keratinocytes are cultured in monolayer and 24 hours or 48 hours after addition of the cenoside Rb to the culture medium at a concentration of 0 to 10 pg / ml, the culture supernatant was collected. Thereafter, the VEGF concentration in the culture supernatant was measured using a human VEGFELISA kit (R & D system). The results are shown in FIG.

 As shown in Fig. 23, 24 hours after the addition of ginsenoside Rb, there was no significant change in VEGF concentration in the culture supernatant compared to the case without ginsenoside Rbt, but ginsenoside Rb Forty-eight hours after the addition of R b, the VEGF concentration in the culture supernatant increased, especially at a concentration of 100 fg / m 1 to 10 pg / m 1, as compared with the case without ginsenoside R bi.

From the above, it has been newly found that ginsenoside R bi induces VEGF expression in cells such as the ostium-site keratinocytes. Therefore, the present inventors next examined whether ginsenoside R bi induces VEGF expression through activation of transcription factor HIF-1. For this reason, first, the B g1 II site on the multiple cloning site of the pGL-3 promoter, Oneichi (Promega), has a repeat sequence of “TACGTG” six times, ie, (TACGTG) _6. Was inserted. By the way,

"TA CGTG" is, HRE on DNA binding transcription factors HIF 1. - a common base Hai歹of (hypox ia response element) (J (consensus sequence) Thus, in the present invention (TAC GT G) ₆ The pGL-3 promoter vector into which is inserted is referred to as HRE leuciferase-plasmid .. As a control, the pGL-3 promoter-vector-1 (plasmid) was used.

Primary culture of astrocytes and nerve cells was performed as follows.

 Astrocytes were isolated by a known method from a Wistar rat immediately after birth, cultured in a culture flask, and replanted two weeks later in a 12-well plate. The astrocyte was published by the present inventors (Sakanaka and Tanaka) (Fujita, H. et al., Glia, 18, 269-281, 1996; Tanaka, J. et al., Glia, 20,

23-37, 1997; Tanaka, J. et al., Glia, 24, 198-215, 1998). Nerve cells were isolated from the 17-day-old embryonic Wistar rat cerebral cortex by a known method and cultured on a 12-well plate coated with poly L-lysine. . Nerve on day 5 of culture Cells were used for gene transfer.

 Gene transfer and luciferase assay were performed as follows.

 Using 1 Hg of plasmid DNA per well (ie, HRE luciferase-plasmid or PGL-3 promoter vector) and 5 l of Lipofectamine (Invitrogen), add 10% FCS Transfection (gene transfer) was performed for 5 hours in the presence. Thereafter, the medium was replaced with a fresh medium and cultured overnight at 37 ° C. The next morning, 0 or 100 ig of ginsenoside Rbi was added, and the cells were cultured at 37 ° C for 24 hours. After the cell surface was washed twice with PBS (phosphate-buffered saline), the cells were lysed with Luciierase Cell Culture Lysis Reagent (Promega) 1001. The amount of luciferase in the solution was measured using a Luciferase Assay System (Promega) and Remine Sensor-JNR (ATO). The results are shown in FIG.

 As shown in FIG. 24, the amount of luciferase increased in the ginsenoside Rbi100 ig / ml-added example compared to the non-added example. This indicates that ginsenosides, such as ginsenoside Rbi, preferably activate the transcription factor HIF-1 in cells such as neuronal astrocytes at a low concentration, and cause HIF-1 and HRE ( hypo xi a-response element). * In FIG. 24 indicates P <0.01. Statistical analysis is based on students' tests.

 Next, the present inventors investigated whether ginsenoside Rbi activates the transcription factor HIF-1 even in human skin keratinocytes. For this purpose, human skin keratinocytes are cultured in a monolayer on a 12-well type 1 collagen dish and transfection of plasmid DNA (ie, HRE-luciferase-plasmid or PGL-3 promoter vector) is performed. did. After 24 hours, the medium was changed and ginsenoside Rbi at a concentration of 0 to 1 ng / m1 was added. After 48 hours, the cells were lysed with Luciierase Cell Culture Lysis Reagent (Promega). The amount of luciferase in the solution was measured using a Luciferase Assay System (Promega) and a luminescence sensor JNR (ATTO). The results are shown in FIG.

As shown in Fig. 25, a control example (PGL-3 promoter vector When HRE-luciferase-plasmid was transfected, the amount of luciferase was increased by the addition of ginsenoside Rb. In particular, the increase in the amount of luciferase was remarkable when 10 fg / ml to lpg gZml of ginsenoside Rbi was added. Therefore, ginsenosides, such as ginsenoside Rb, activate the transcription factor HIF-11 in all cells, including the ostium mouth or human skin keratinocytes, and induce the binding of HIF-1 to HRE. It is thought to be. One of the transcription factors, Hypoxia Inducible Factor-1 (HIF-1), is a heterodimer consisting of HIF-la and HIF-lj3. It is considered an activated factor. Regarding the mechanism of HIF-1 activation by hypoxia, to date (1) HIF-la mRNA is markedly induced by hypoxia-ischemia; (2) HIF-1a is ubiquitin-protein It is degraded in the lysosomal system, but its degradation is suppressed under hypoxia. (3) It is reported that HIF is regulated by three kinds of mechanisms; .

 The list of genes or gene products whose gene expression is induced by binding of the transcription factor HIF-1 to a hypoxia response element (HRE) on DNA, and their effects are described below.

 1. Erythropoietin (EPO): Differentiates and proliferates erythroid progenitor cells into erythrocytes, thereby promoting erythrocyte production and increasing oxygen supply to the whole body. Therefore, EP〇 is mainly used as a remedy for renal anemia.

 (2) Transferrin and its receptor: Transferrin is an iron transport protein, which transports iron to the bone marrow by binding to iron absorbed from the food into the body, where it can be used for hemoglobin synthesis.

 (3) VEGF (Vascular endothelial growth factor) and its receptor FLT-1: Promote angiogenesis or revascularization and increase local oxygen supply.

(4) Glycolytic enzymes, such as aldolase A and C; phosphofrue tokinase L and C; phosphoglycerate kinase-1 (C) PGK-1)); Lactate dehydrogenase:)-ze-A (lactate dehydrogenase-A (LDH-A)); pyruvate kinase M (pyruvate kinase M) ； enora 1 A

 (5) Type 1 and type 3 glucose transporter overnight (GLUT 1; GLUT 3): Promotes the uptake of glucose into cells and enables the cells to undergo anoxic respiration.

(6) Adenylate kinase 3: catalyzes the reaction of AMP + ATP → 2 ADP. This reaction is important as the first step of AMP-ATP, that is, the first step of ATP production.

 (7) Heme Oxygenase-1 (HO-1): Heme is decomposed into CO (—carbon oxide) and pyriberdine. The generated CO protects cardiomyocytes and nerve cells from low oxygen by vasodilator action.

 (8) Tyrosine dehydrogenase: a catecholamine synthase.

Based on the above, HIF-1 can be used for (1) diseases or conditions that cause vascular injury or impaired blood flow through increased expression of VEGF and its receptor (eg, wounds, fractures, burns, hemorrhoids, radiation damage) Prevention, treatment or treatment of cerebrovascular disorders, angina pectoris, myocardial infarction, laser injuries, Reino's disease, collagen disease, atherosclerosis obliterans, skin ulcers, diabetic skin ulcers, heart failure, pressure sores, etc.) 2) Prevention, treatment or treatment of anemia, renal anemia and secondary anemia through increased expression of erythropoietin and transferrin, (3) glycolytic enzymes, glucose transporter, adenylate kinase 3 and Protects cells in a hypoxic environment through increased expression of HO-1 and thereby prevents, treats or treats cerebral infarction, angina pectoris, and myocardial infarction. (4) Through increased expression of tyrosine dehydrogenase The power teko Allowed increased amine production amount, has been the prevention of heart failure, are their respective useful for the treatment or therapy. Therefore, like HIF-1, pharmaceutical compositions such as ginsenosides that activate the transcription factor HIF-1 also include wounds, bone fractures, burns, hemorrhoids, radiation damage, cerebrovascular disease, laser damage, Reino disease, Prevention, treatment or treatment of collagen disease, arteriosclerosis obliterans, skin ulcers, diabetic skin ulcers, pressure sores, anemia, renal anemia, secondary anemia, cerebral infarction, angina pectoris, cardiac infarction or myocardial infarction Will be useful. These diseases and conditions are, of course, included in diseases that cause impaired blood flow. In addition, it has been reported that mice lacking the hypoxia response element (IIRE) that binds to HIF-1 cause motor neuron cell death and exhibit a pathology similar to amyotrophic lateral sclerosis (ALS). (Oosthuyse B. et al., Nature Genetics, 28, 131-138, 2001). Presumably, it also prevents, treats, and treats diseases that cause neuronal death (eg, neurodegenerative diseases such as ALS, Alzheimer's disease, and Parkinson's disease) through the protective effect of VEGF on neuronal cells and the blood flow improving effect. Considered useful.

 As described above, ginsenosides such as ginsenoside Rt or natural ginsenosides can be converted into erythropoietin, transferrin, transferrin receptor, VEGF, and VEGF through activation of transcription factor HIF-1. Body (FLT-1), glycolytic enzymes (aldolase A, aldolase C, phospho rue tokinase L, phosp of r uctokinase C, phosphoglycerate kinase-1, lactate dehydrogenase A, pyruva te kinase M, enolase A) , Type 1 glucose transporter, type 3 glucose transporter, adenylate kinase 3, heoxygenase 1 (HO I) or tyrosine dehydrogenase . More specifically, the pharmaceutical composition comprising the ginsenosides of the present invention comprises a wound, a bone fracture, a burn, a hemorrhoid through the action of the gene product or a physiologically active substance whose expression is induced by the transcription factor HIF-1. Radiation injury, cerebrovascular disease, Reino's disease, collagen disease, arteriosclerosis obliterans, Baja disease, diabetic skin ulcer, skin ulcer, laser injury, pressure sore, anemia, secondary anemia, renal anemia, It is considered to be useful for preventing, treating or treating diseases that cause blood flow disorders such as diseases involving nerve cell death, amyotrophic lateral sclerosis, cerebral infarction, angina, heart failure or myocardial infarction.

 Now, as described above, the present inventors have clarified that ginsenoside derivatives such as dihydrozincenoside Rbi induce the expression of VEGF mRNA in nerve cells. Then, the present inventors next examined whether the ginsenoside derivatives promoted the expression of VEGF mRNA in astrocytes in the same manner as ginsenoside Rb !. Therefore, as a representative example of the ginsenoside derivatives, an experiment was carried out by selecting a reduced derivative, that is, dihydrozincenoside R b represented by the above structural formula.

Astrocytes were isolated from the Wistar rat immediately after birth by a known method, cultured in a culture flask, and 12 days later, a 10 cm dish (10 cm) coated with poly-L-lysine was used. dish). Astrosites were cultured in DMEM medium containing 10% fetal calf serum (FCS). After 3 to 4 days, change to serum-free medium and The hydrozincenoside Rbi was added at a concentration of 0, lfg / ml, and 100 fg / m1, and cultured for 6 hours. The astrocyte was published by the present inventors (Sakanaka and Tanaka) (Fujita, H. et al., Glia, 18, 269-281, 1996; Tanaka, J. et al., 1996). Glia, 20, 23-37, 1997; Tanaka, J. et al., Glia, 24, 198-215, 1998).

 Thereafter, total RNA was extracted from the cultured astrocytes. After DNase treatment, cDNA was prepared from 3 ig of total RNA using oligo dT primer and reverse transcriptase. The PCR reaction was performed using Taq polymerase according to Tonella's paper (Tonello, FEBS Letters, 442, 167-172, 1999). The PCR-primer and PCR reaction conditions used are as follows. Β-actin is an internal standard. (1) β —

 The PCR product generated after development was electrophoresed on a 3% agarose gel and visualized by ethidium bromide staining. The results are shown in FIG. Figure 26 is a photograph replacing the drawing.

As shown in Fig. 26, as compared to the astrocyte without the dihydrozine senoside Rbi, the dihydrozine senoside Rb was added at a concentration of 1 f / m1 or 100 fg / m1. VEGF mRNA expression was enhanced in trocites. The VEGF of the rat is divided into three subtypes, VEGF120, VEGF164, and VEGF188, corresponding to the number of constituent amino acids. At least two are allowed as shown in the figure. Next, the present inventors used Western blotting with an anti-VEGF monoclonal antibody (manufactured by Sunshine Cruz) to examine whether dihydrozincenoside R bi enhances not only VEGF mRNA but also VEGF protein expression in neuronal cells. The law was implemented. Rat cerebral cortical neurons were cultured for 24 hours in the presence or absence of dihydrozincenoside Rbt, and the cells were lysed with a sample buffer for electrophoresis, and electrophoresis was performed. Thereafter, the electrophoretic protein was transferred to a Nitrocellulose membrane and subjected to Western blotting. For details of the experimental technique of the Western plot, see the papers already published by the present inventors (Sakanaka, Tanaka) (Wen T.-, et al., J. Exp. Med., 188, 635-649, 1998). The results are shown in FIG. Figure 27 is a photograph of a Western plot that replaces the drawing.

 Further, the band reacting with the anti-VEGF antibody was quantified by an image analyzer. The results are shown in Figure 28.

 As shown in FIGS. 27 and 28, dihydrozincenoside R bi significantly increased the expression level of VEGF protein in neurons in the optimal concentration range of 1 to 100 ig / ml. * In Figure 28, * indicates P <0.01, and the statistical analysis method is based on ANOVA + Fisher's PLSD. From the above results, it can be said that ginsenoside derivatives such as dihydrozincenoside Rb also enhance VEGF expression in cells, like ginsenoside Rb. Moreover, as described in PC TZ JP 00/0555554, the pharmacological actions of dihydrozincenoside Rb and ginsenoside Rbt are extremely similar, and of course, Like ginsenoside R b, it is thought to upregulate VEGF expression in cells through activation of transcription factor HIF-1.

Therefore, ginsenoside derivatives such as dihydroginsenoside Rb can be used to activate erythropoietin, transferrin, and transferrin via activation of the transcription factor HIF-1 in cells such as neurons of the ostium. Body, VEGF, VEGF receptor (FLT-1), glycolytic enzymes (aldolase A, aldolase C, phosphofru ctokinase L, posphofuret okinas e C, phosphoglycerate kinase-1, lactate d ehydrogenase A, pyruvate kinase M, enolase A), type 1 glucose transporter, type 3 glucose transporter, adenylate kinase 3, hemeoxygena It can be said to promote the expression of heme oxygenase 1 (HO I) or tyrosine dehydrogenase. More specifically, a pharmaceutical composition comprising the ginsenoside derivative of the present invention can be used for treating wounds, fractures, burns, hemorrhoids through the action of the gene product or a physiologically active substance whose expression is induced by the transcription factor HIF-1. , Radiation injury, cerebrovascular disease, Reino disease, collagen disease, arteriosclerosis obliterans, Bajaja disease, diabetic skin ulcer, skin ulcer, laser injury, pressure sore, anemia, secondary anemia, renal anemia It is considered to be useful for preventing, treating or treating a disease associated with nerve cell death, a cerebral infarction, angina pectoris, a disease causing a blood flow disorder such as heart failure or myocardial infarction. In the present invention, it has already been described that ginsenoside derivatives are also included in ginsenosides. Example

 Next, the present invention will be described in detail with reference to specific test examples, but the present invention is not limited to these specific examples. Example 1 (Experiment for making dihydrozine cenoside Rbi)

 The present inventors first prepared dihydrozincenoside Rbi.

 The production examples and NMR data of dihydrozincenoside R b are shown below. (1) 10% Pd / C (palladium charcoal) 10.2 mg is weighed and placed in a two-necked flask with active oxygen. (2) 1 ml of methanol (special grade) is added and suspended. .

(3) Attach a hydrogen balloon (about 1.1 atm) and activate the catalyst at 0 ° C for 30 minutes.

(4) Dissolve 9.9 mg of ginsenoside R bi in 1 ml of methanol and inject with a syringe. (5) Stir the mixture vigorously with a magnetic stirrer at 0 ° C for 10 1/2 hours. (6) Filter the reaction mixture through filter paper and a 0.45 m membrane filter. (7) Remove methanol under reduced pressure. (8) After dissolving in 10 ml of pure water and freeze-drying, 19.1 mg (97% yield) of dihydrozincenoside Rb was obtained as a white powder. The melting point of dihydrozincenoside Rbi is 193-195 ° C. Incidentally, the melting point of ginsenoside R bt is 197-198 ° C. (literature value). Figure 1 shows the NMR chart (400 MHz, CDsOD) of dihydrozine senoside Rbi. Example 2 (Anti-apoptotic effect of dihydrozincenoside Rt)

 Next, the present inventors first examined the concentration at which the dihydrozine senoside Rbi obtained by the above-mentioned method exerts a favorable effect on cells in a usual culture experiment. For this reason, the present inventors examined the concentration at which apoptosis or apoptotic-like neuronal death of cultured neurons was suppressed by dihydrozine senoside Rbi.

 The present inventors (Sakanaka and Tanaka) show that cultured neurons are exposed to the nitric oxide donor, sodium nitroprusside (SNP), for a short period of time. It has been reported that death is induced (Toku K. et al., J. Neurosci. Res., 53, 415-425, 1998). Using this culture experiment system, the present inventors have already found that ginsenoside R bi can induce apoptosis of neurons or apoptotic-like neuronal death in the optimal extracellular solution concentration range of 1 to 100 fg / 1. Have been found to be deterred (WO 00/374841). Therefore, the neuroprotective effect of dihydrozine senoside Rb was examined using a similar experimental system.

Nerve cells were isolated from the fetal cerebral cortex of a 17-day-old rat fetal cerebral cortex using trypsin EDTA, and plated on a polyerizin-coated 24-well plate. After culturing for 16 hours in Dulbecco's modified Eagle's medium (DMEM) containing 10% fetal calf serum, the culture is cultured in neural cells containing insulin, transferrin, etc. The medium was replaced with a serum-free medium and cultured for 3 to 4 days. On the third or fourth day of the culture, sodium nitroprusside (SNΡ) was added at a concentration of 300 µΜ, and the mixture was incubated for 10 minutes. Thereafter, the culture solution was replaced with Eagle's minimum essential medium (EMEM) containing dihydroginsenoside Rbi (0 to 1 ng / 1) and bovine serum albumin. Sixteen hours after SNP loading, neurons were lysed using a Laemmli electrophoresis sample buffer, polyacrylamide gel electrophoresis was performed, and the migrated proteins were transferred to a nitrocellulose membrane. Immunoblotting was performed using an antibody against the specific protein MAP2. Immunostained MAP2 bands were analyzed by densitometry to quantify neuronal cell viability and no or process elongation. The results are shown in FIGS. 2 and 3. Details of the experimental procedure of MAP 2 Is described in a published paper of the present inventors (Sakanaka, Tanaka) (Wen, T-et al., J. Exp. Med., 188, 635-649, 1998).

FIG. 2 is a photograph in place of a drawing showing the result of the immobilization of microtuble-associated protein 2 (MAP 2). The first lane from the left is a control cultured neuron, in which a clear MAP 2 band (ie, a band of nerve cells) was observed. The SNP treatment caused many neurons to undergo apoptosis or apoptosis-like neuronal death, so that the MAP2 band was clearly weakened, as in the second lane from the left. If dihydro rosin senoside Rt is added to the culture medium at a concentration of 0.01 fg / ml (lane 3) to lng / ml (lane 7), neuronal apoptosis by SNP or Apoptosis-like neuronal cell death was clearly suppressed, and as a result, a strong band of MAP2, which is an indicator of neuronal cell survival and / or process extension, was observed. Fig. 3 shows the results of the above-described simulated noblot experiment of MAP2 repeated five times, and the results were analyzed by densitometry. As shown in Fig. 3, dihydrozincenoside R bi in the optimal extracellular fluid concentration range of 0.01 fg / ml to lng Zm 1 significantly decreased neuronal apoptosis or apoptotic-like neuronal cell death. Turned out to be deterrent. In other words, dihydrozincenoside Rbi has a favorable anti-cellular activity, particularly against nerve cells, in an optimal extracellular solution concentration range that is considerably wider than that of disenozide Rbi described in WO 00/37481. It is thought to exert an apoptotic effect. Possibly, ginsenoside derivatives such as dihydrozincenoside Rbi also promote regeneration and / or remodeling of nerve tissue by extending neurites. Therefore, ginsenoside derivatives such as dihydrozincenoside Rb have an extracellular fluid concentration of 100 g / m1 (about 90 M) or less, preferably 100 ng / m1 (about 90 nM) or less, more preferably 1 ng / m1 (about 0.9 nM) or less, and still more preferably 0.0000 0.001 fg / ml (about 0.0000 It is considered that by inhibiting apoptosis or apoptosis-like cell death of cells at fM) to 100000 fg / ml (approximately 900 fM), an excellent cytoprotective effect is exerted. In other words, ginsenoside derivatives such as dihydrozincenoside Rb cause cells of living tissues exposed to impaired blood flow to have anti-apoptotic effects. It is thought to protect through use. Ginsenoside derivatives such as dihydroginsenoside R b, etc. are used for transplantation tissues and organ cells (stem cells, ES cells, skin keratinocytes, etc.), cells derived from all tissues, frozen cells for transplantation, blood cell components for blood transfusion, It may also be useful for the protection or preservation of platelets and germ cells (frozen eggs or sperm). In FIG. 3, * indicates P <0.0001, and ** indicates P <0.0001. Statistical analysis is based on the post hoc test of AN OVA + Schedule. Example 3 (Effect of dihydrozincenoside Rbi on cerebrovascular disorders)

 As described above, ginsenoside derivatives such as dihydrozincenoside Rbi can be used for cells, particularly for neurons, in an extracellular solution concentration range that is considerably wider than the ginsenoside Rbi described in WO 00/37481. Inhibition of apoptosis or apoptosis-like neuronal cell death has been shown in an in vitro experimental system, but dihydrozine senocysis has also been demonstrated in an in vivo animal experimental system that actually causes blood flow disorders. The inventors of the present invention next examined whether or not ginsenoside derivatives such as de Rbi exhibited excellent effects similarly to the ginsenoside Rbt described in WO 00/37481. For this reason, for example, cerebrovascular disorders are selected as the diseases that cause blood flow disorders as follows, and intravenous administration of dihydrozincenoside Rbi, one of the derivatives of ginsenosides. Treatment of cerebrovascular disorders, especially cerebral infarction I checked whether it is effective.

 Approximately 12 to: A 16-week-old male stroke-prone spontaneously hypertensive rat (SH—SP rat, weight: 280—320 g) was used. The animals were housed in a 12-hour light-dark cycle room with free access to water and food. Under inhalation anesthesia, the left middle cerebral artery cortical branch (MCA) of the animal was coagulated and dissected. A single intravenous injection (6 g or 0.6 wg) of dihydrozine senoside Rb immediately after permanent MCA occlusion, followed by continuous infusion of dihydrozine senoside R bi intravenously for 24 hours using an Alzamini osmotic pump (6 β g Z or 0.6 ^ g days) (n = 6). The details of this experimental technique are described in a published paper by the present inventors (Sakanaka, Tanaka) (Igase K. et al., J. Cerebral. Blood Flow Metab., 19.298-). 306, 1999).

Control animals in which MCA was permanently occluded (ischemic control animals) were intravenously administered only the same amount of saline (vehicle, carrier or vehicle) (n = 7). MCA At the post-occlusion time, a lethal dose of pentobarbital was injected intraperitoneally into the rat. Immediately after the animal died, the brain was removed and a 2 mm thick forehead section was prepared. The sections were immersed in a 1% 2,3,5—2,3,5-chloride (2,3,5-triphenyl-tetrazolium chloride (TTO) solution for 30 minutes at 37 ° C. The cells were fixed in 0% formalin for at least 12 hours The results are shown in Fig. 4 and Fig. 5. Fig. 4 shows two cases of administration of physiological saline, and Fig. 5 shows dihydrozine cenoside R b 6 g Two cases of intravenous administration on day Z are shown.

 As shown in FIG. 4, in rats to which saline was administered after permanent MCA occlusion, a white cerebral infarction lesion not stained with TTC was clearly observed in the left cerebral cortex. On the other hand, as shown in FIG. 5, cerebral infarction lesions were significantly reduced in rats administered intravenously with dihydrozincenoside Rbi after MCA permanent occlusion.

 The cerebral infarction area of the cerebral infarction rat (n = 6) administered intravenously with dihydrozincenoside Rb and the cerebral infarction area (n = 6) of the cerebral infarction rat administered only vehicle (vehicle (carrier or vehicle)) 7) was compared. The results are shown in FIG. As shown in Fig. 6, the cerebral infarction area of the cerebral infarction group of the cerebral infarction group treated with dihydridine senoside R bi (2H-Rbi) was compared with that of the cerebral infarction group treated with the vehicle (saline). Was reduced to about one third. The statistical analysis method in Fig. 6 is based on the Mann-Whitney test, and the ** mark indicates 0.01.

Based on the above, the therapeutic effect of dihydrozincenoside Rbi on cerebrovascular disorders, particularly the therapeutic effect on cerebral infarction, is excellent enough to be comparable to the effect of ginsenoside Rbi and the like disclosed in WO0000374881. Turned out to be. In other words, it can be said that ginsenoside derivatives such as dihydrozine cenoside Rbi are effective and efficacious in diseases or conditions that cause impaired blood flow such as cerebrovascular disorder and cerebral infarction. In addition, it is considered that ginsenoside derivatives such as dihydroginsenoside R bi promote regeneration and / or remodeling of cerebral blood vessels, similarly to ginsenoside Rb described in WO 00/48608. Was done. Therefore, the present inventor further increased the intravenous dose of dihydrozine senoside Rbi by a factor of 2 (single administration of 12 ig followed by continuous administration at a dose of 12 ig / day). After examining whether or not it could be obtained, no excellent effect was found as expected. In other words, ginseng in W〇 00/3 7 4 Noside Rb showed an excellent cerebral infarction treatment effect even at a dose of 6 / day on SH-SP rats weighing about 300 g, but ginsenoside derivatives such as dihydrozincenoside R bi It was considered that such a high dose did not necessarily exert a cerebral infarction therapeutic effect and / or a cerebral blood vessel regeneration / remodeling promoting effect.

 Therefore, the optimal dose of dihydrozincenoside; R for a cerebral infarction rat with a body weight of about 300 g is lower than the optimal dose of ginsenoside Rbi, and in particular, is preferably 60 igZ days or less. It was considered to be less than 12 zg / day. Thus, in culture experiments, dihydrozincenoside R bi inhibits apoptosis or apoptotic-like neuronal cell death of neurons in a broader concentration range than ginsenoside R bi, but in vivo. Dihydrozincenoside Rb has excellent cerebral infarction treatment effect and cerebral vascular regeneration / regeneration in the same dosage amount as ginsenoside Rbi, or as low as 1/10 to 1/100 of that amount. It can be said that it has a construction promoting effect. However, other ginsenoside derivatives such as dihydroxidine senoside R bi or epoxy ginsenoside R bi may be used at a dosage and concentration that is equivalent to or approximately 100 times higher than ginsenoside R bi. It is thought to show the same effect as bi. Example 4 (Experiment for judging the effect of dihydrozine cenoside Rbi on the treatment of spinal cord injury)

 The present inventors have further investigated whether low doses of dihydrozine cenoside Rb also have a favorable effect on nerve trauma causing blood flow disorders. By the way, neurological trauma such as spinal cord injury and head trauma also causes blood flow disorders due to rupture of blood vessels and edema of brain and spinal cord tissues, leading to irreversible higher-order neuropathy. Therefore, the present inventors took spinal cord injury as one of the diseases causing blood flow disorder, and dihydrozincenoside Rb! The effect of was decided to be investigated. For this reason, the following is an example of an experiment in which dihydridine senoside Rb! Was infused intravenously into a spinal cord injury rat (body weight: about 300 g) for 7 days at a dose of 1.2 g Z days.

Under inhalational anesthesia with halothane and laughter, 20 g of pressure was applied to the lower thoracic spinal cord of the rat for 20 minutes, and after 30 minutes or more, dihydrozine cenoside R bid.2 was injected into the left femoral vein. g) and a single injection of dihydrozincenoside R bid 2 g / day) was continuously administered for 7 days using an Alzamini osmotic pump. Control animals received the same amount of saline (vehicle, carrier or vehicle) on a similar schedule. The results are shown in FIGS. 7 and 8.

 The left photographs of Figs. 7 and 8 show the saline administration rats on the second day after spinal cord injury, and the right photographs of Figs. 7 and 8 show dihydrozincenoside Rb 1.2 gZ at the same time. Days) administration rats are indicated. As shown in the left-hand photographs of Figs. 7 and 8, the saline administration rat with 20 g of pressure applied to the lower thoracic spinal cord for 20 minutes was used not only on the day of spinal cord injury but also after spinal cord injury. He also had paraplegia on both legs on day. However, when 20 g of pressure was applied to the lower thoracic cord for 20 minutes, continuous administration of dihydrozine senoside scale intravenously at a dose of ^ 2 μg Z days resulted in lower extremity paraplegia on the day of spinal cord injury. On the second day after spinal cord injury, however, paraplegia of both lower limbs improved markedly, and the rat was able to stand up while holding onto objects, as shown in the right-hand photographs in Figs. 7 and 8. Became. In addition, dihydrozine senoside Rbi was administered intravenously to spinal cord injury rats at a dose of 8 ii gZ days after a single dose of 8 / ig or 60 βg / day after a single dose of 60 Hg. However, no excellent effect was observed.

Based on the above, ginsenoside derivatives such as dihydrozincenoside R bi are superior to the spinal cord in comparison with the ginsenoside R bi described in WO 00/46808. Injury · It was found to be effective in treating nerve trauma. In addition, the optimal dose of dihydrozincenoside Rb for spinal cord injury rats weighing 300 g was considered to be 6 days or less, preferably around 1.2 ig / day or less. That is, when dihydrozincenoside Rb is used as a pharmaceutical composition for treating nerve trauma, head trauma-spinal cord injury, the optimal dose is W〇00 / 468680 or PCT / JP0. The optimal dose of ginsenoside Rbi described in 0/04201 (about 60 ig _ / day for a rat weighing 300 g) is about 50% or less. It turned out to be. As mentioned above, dihydrozincenoside R can be prepared from high-purity ginsenoside Rb at a yield of 97%, so dihydrozincenoside Rb is more efficient than ginsenoside Rbi. It can be used for the prevention, treatment, and treatment of neurological trauma, brain that causes blood flow disorders such as stroke, and neurological diseases. Based on the above experimental results using cerebrovascular accident (cerebral infarction) model animals and spinal cord injury model animals, ginsenoside derivatives such as dihydrozincenoside Rbi indicate that blood flow disorders are caused by diseases such as cerebrovascular disorders and spinal cord injuries. It has been invented to be a pharmaceutical composition for prevention, treatment or therapy. Presumably, ginsenoside derivatives such as dihydrozincenoside Rbt inhibit diseases of blood flow by inhibiting cell apoptosis or apoptosis-like cell death and promoting the regeneration and remodeling of blood vessels, resulting in impaired blood flow. (Eg, cerebrovascular disorder, head trauma, nerve trauma, moyamoya disease, spinal cord injury, etc.), it is considered to be effective and effective in treating or treating. Example 5 (Open wound treatment with external preparation for skin containing dihydrozincenoside R b)

Next, the present inventors examined whether or not ginsenoside derivatives such as dihydrozincenoside Rt are effective against diseases in which blood flow is impaired due to disruption or cutting of blood vessels. For this reason, wounds, especially open wounds, were selected as diseases in which blood vessels were disrupted or severed, and the therapeutic effect of dihydrozincenoside Rbi on open wounds was examined. Under inhalation anesthesia, a punch biopsy having a diameter of 6 mm was applied to the back of a rat (n = 4) at five locations to create open wounds. As a result, the blood vessels in the same area are instantaneously cut, and blood flow obstruction occurs in the open wound. Thereafter, each open wounds, 0 respectively mercy Dorojinsenosai de R b. 0 0 0 1 wt% (1 0 ^4% by weight), 0.0 0 0 0 1 wt% (1 0 ⁵ wt%), 0 . 0 0 0 0 0 1 wt% (1 0 ⁶ wt%), 0.0 0 0 0 0 0 1 wt% (1 ^0-7 wt%), of at a concentration Puropeto (ophthalmic white (Cerine) was applied once daily for 0.1 day 9 days. Only the same amount of the plot was externally applied to the control. Immediately after the animal was euthanized by anesthesia, the wound skin was collected and photographed. The collected skin tissue was stored in a fixative. Figure 9 shows the results. Figure 9 is a photograph replacing the drawing. FIG. 9 shows four examples, in which the first example, the second example, the third example, and the fourth example are shown from above. Each two left side, there are traces of open wounds in total 5 places three increments to the right, from the top of the left 1 0 - For ⁴ wt%, in the case of 1 0 ⁵ wt%, on the right from 1 0 _ ⁶ wt%, 1 0 - for ⁷ wt%, shows the case of 0% (control). 9 0.0 0 0 0 1 wt% as shown in FIG. (1 ^0-5 wt%) from 0.0 0 0 0 0 0 1% by weight of dihydrazide Dorojinsenosai de R bi (1 ^0-7 wt%) It is clear that topical application of dihydrozine senoside Rb at a concentration of 100 ng / g to I ng / g to open wounds clearly indicates that compared to open wounds where only the protocol was applied externally. Wound healing was promoted, and in the case of topical administration of low-concentration dihydrozincenoside Rb 丄, obvious hair growth was observed in the wound healing area. When the derivative is used as an external preparation for skin, the concentration of the composition in the external preparation is not more than 0.001% by weight or less, preferably not more than 0.001% by weight, more preferably not more than 0. . 0 0 0 0 0 0 1 wt% (1 ^0-7 wt%) to set the front and rear or less Therefore, for the prevention, treatment or treatment of diseases that cause impaired blood flow (for example, wounds, burns, pressure sores, laser injuries, skin ulcers, hemorrhoids, etc.), dihydrozincenoside R bi etc. When a pharmaceutical composition comprising a ginsenoside derivative is topically or topically administered, the concentration of the composition in a topical or topical skin preparation is 0.001% by weight or less, preferably less than 0.01% by weight. 1 wt% (1 0 ⁵ wt%) or less, more rather preferably has 0.0 0 0 0 0 0 1 wt% (1 0 ^7% by weight) is preferably set in the following. prevention of the disease, The upper limit of the concentration of the ginsenoside derivative in the external preparation for skin or topical administration for treatment or therapy is 1% by weight or less, preferably 0.1% by weight or less.

In the experimental example described above, Ri DOO denominator area of open wound that topical application of Puropetonomi, 0.0 0 0 1 wt% (1 0 ^4% by weight) force al 0.0 0 0 0 0 The area of an open wound to which 1% by weight (10 to ¹⁷ % by weight) of dihydrozincenoside Rbi was applied externally was taken as a molecule, and the ratio was calculated. The results are shown in FIG. In FIG. 10, the symbol * indicates that there is a significant difference between P and 0.05 when n = 4. The test is based on Fisher's PLSD.

As shown in the first 0 figure 0.0 0 0 0 1 wt% (1 0 ⁵ wt%) the mercy Dorojinsenosai de R bt the following concentrations topically administered to open wound promotes regeneration and reconstruction of cutaneous tissue And significantly promoted wound healing. Lay in particular 0.0 0 0 0 1 wt% (1 0 one ⁵ wt%) or less following dihydric Dorojinsenosai de R b ie 1 0 0 ng / g The fact that topical administration of dihydrozincenoside R bi at 100 ng / m 1 or less significantly reduced open wounds is due to the fact that ginsenoside derivatives such as dihydrozinsenoside R bi are extracellular in affected tissues. The liquid concentration is 100 gZm1 or less, preferably 100 ng / ml or less, more preferably 1 ng1 or less, and even more preferably 0.0000 001/100 ng / ml. At this time, he strongly supports the rapid promotion of wound healing by remarkably promoting the regeneration or remodeling of blood vessels. In the early stage of wound healing, vascular endothelial cells, vascular smooth muscle cells, epithelial cells, epidermal keratinocytes, stem cells, fibroblasts, etc. are actively dividing, as described in PCTZ JPO 0555554. · Proliferates to form a large number of new blood vessels and regenerative blood vessels, but once the wound heals, these new blood vessels or regenerative blood vessels will regress or disappear from the excess. This phenomenon will be referred to as PC TZ JP 0/055 54 and in this specification, vascular reconstruction. In other words, in the regeneration and remodeling phenomena of all living tissues, contradictory events such as cell division, proliferation, migration and differentiation, adhesion, and mitotic growth arrest must occur in an orderly manner. b can be said to adjust these events cleverly. Therefore, if dihydrozin cenoside Rb selectively exerts the vascular remodeling promoting action, the pharmaceutical composition is also useful for the prevention, treatment or treatment of malignant neoplasms (including cancer and sarcoma). .

From the above experimental results, it can be seen that topical application of low-concentration ginsenoside derivatives, especially dihydrozincenoside Rb, not only promotes regeneration and reconstruction of cut blood vessels, but also enhances skin epidermal tissue and dermis. It is thought to promote regeneration and remodeling of connective tissue, dermal papillae, sebaceous glands, nerves, sweat glands, dermal papilla, pilo erectoris, hair follicles, etc., and accelerate wound treatment. To the inventor's knowledge, the effect of topical administration of dihydrozincenoside Rbi at a low concentration is far superior to that of peptidic factors (PDGF, EGF, bFGF). The ointment or topical preparation containing dihydrozincenoside Rb at a low concentration used in this experiment may be used not only on the skin but also on any organ, tissue (cornea, tissue, etc.) that has caused wounds, injuries, impaired blood flow, or histopathological changes. External application to oral mucosa, outer ear, gastrointestinal mucosa, nasal mucosa, tympanic membrane, vagina, bladder, uterus, urethra, airway mucosa, rectum, .anus, etc.) to regenerate and regenerate diseased tissues including blood vessels Construction can be accelerated. In particular, suppositories containing ginsenosides are used for the prevention, treatment or treatment of hemorrhoids. Topical administration to the anus, z, or rectum (mucosa) provides excellent results. As a result of this experiment, it was found that the amount of ginsenoside derivatives, especially dihydrozinosine Rbi, per 10 g of the product mixed was 0.1 mg or less, and preferably 0.1 mg or less. did. In other words, the optimal skin external dose of ginsenoside derivatives, particularly dihydrozinsenoside Rbi, to humans or vertebrates having skin diseases is considerably small. When a ginsenoside derivative such as dihydrozincenoside Rb is mixed per 10 g of the protein for the purpose of preventing, treating or treating the above-mentioned disease, the upper limit thereof is 0.1 lg or less, preferably 0.1 OO lg. It is as follows. Example 6 (Promotion of Bcl-X LmRNA expression, suppression of VEGF mRNA expression or suppression of caspase 3 mRNA expression in neuronal cells by dihydrozincenoside Rb) As described above, the pharmaceutical composition of the present invention has anti-apoptosis It is thought to prevent, treat or treat diseases or conditions that result in impaired blood flow through its action as well as its revascularization-promoting remodeling action. Then, the inventors of the present invention found that ginsenoside derivatives such as dihydrozincenoside Rbi expressed the main factors (molecular groups) involved in cell apoptosis or blood vessel regeneration and remodeling. I checked whether to adjust. Therefore, as a typical molecules involved in § Pot one cis or apoptosis-like cell death, B c 1 - a X _L and caspase 3, taken up VEGF Exemplary molecules involved in revascularization and Roh or rebuilding, of We examined whether the expression of the molecular group was changed by dihydroginsenoside Rbi.

Experimental techniques are described in the published papers of the present inventors (Sakanaka, Tanaka) (Wen, TC. Et al., J. Ep. Med., 188, 635-649, 1998) and Toneguchi et al. ) (FEB S Letters, 442, 167-172, 1999). Cerebral cortical neurons isolated from the embryonic day 17 rat were cultured in a medium containing 10% fetal calf serum. On the second day of the culture, the medium was replaced with a serum-free medium. On the third day of the culture, dihydrozincenoside Rb was added at a concentration of 0, 1, or 100 fg Zml, and the cells were cultured for 6 hours. Thereafter, total RNA was extracted from the cultured neurons. After DNAase treatment, cDNA was prepared from 3 μg of total RNA using oligo dT primer and reverse transcriptase. PCR reaction uses Taq polymerase I went. The PCR-primers used and the PCR reaction conditions are as follows. Incidentally, 3-actin is an internal standard.

 The PCR product generated after development was electrophoresed on a 3% agarose gel and visualized by ethidium bromide staining. The results are shown in FIG. 11 and FIG. Figures 11 and 12 are photographs replacing the drawings.

As shown in Fig. 11, compared to the neurons without dihydrozincenoside Rb, Bc1 was found in the neurons supplemented with dihydrozine senoside Rb at a concentration of 1,100 fg / m1. - the expression of X _L and VEGF m RNA is enhanced. In particular, the strongest expression of VEG FmRNA was observed in the 1 fg / m1 addition group. The rat VEGF is configured According to the number of amino acids to be used, VEGF120, VEGF164, and VEGF188 can be divided into three subtypes, so that the VEGFmRNA band is at least 2 as shown in Fig. 11. This is recognized. Furthermore, as shown in Fig. 12, compared with the neurons without dihydrogen ginsenoside Rb, the caspases were higher in the neurons to which dihydrozinsenoside Rb was added at a concentration of 1,100 fg / m1. 3 mRNA expression was suppressed. In particular, the strongest suppression of caspase 3 mRNA expression was observed in the 1 fg / m1 addition group.

 Based on the above, ginsenoside derivatives, especially dihydroginsenoside R b, are composed of books such as B e 1 — or caspase 3 (Experimental Medicine, Vol. 17, No. 13, Planning, Shigeichi Nagata, 1999, Yodo Increasing, decreasing or regulating the expression of the apoptosis-related molecule group described in A. et al. Suppresses apoptotic or apoptotic-like cell death. Ginsenoside derivatives, especially dihydroginsenoside R, are described in the publications such as VEGF (Experimental Medicine, Vol. 17, No. 6, Planning, Masashi Shibuya, 1999, Yodosha). It is thought that increasing, decreasing or regulating the expression of the assembly-related molecules promotes the regeneration and remodeling of blood vessels.

That is, dihydric Dorojinsenosai de R b pharmaceutical compositions ing from Jinsenosai earth derivatives Dian, B e 1 - and through the promotion and Z or caspase 3 inhibited the expression of x _L expression, apoptosis all cell types or It is used for the prevention, treatment, and treatment of diseases (including pathological conditions) that inhibit apoptotic cell death and cause cell death. Of course, ginsenoside derivatives such as dihydroxydine senoside Rb may also enhance, attenuate or regulate the action of Bc1-1 and / or caspase-3 transcription factors (eg, NFKB, STATS, etc.). . Diseases that cause cell death, for which the pharmaceutical composition of the present invention is expected to be applied, are described in PCT / JP00Z04102. In addition, the pharmaceutical composition of the present invention has an action of promoting the regeneration and remodeling of blood vessels in addition to the above-described anti-apoptosis action, and thus, through these two actions, a disease or a disease that causes impaired blood flow. Useful for the prevention, treatment, or treatment of conditions. Diseases and conditions that cause blood flow disorders have been described herein. Example 7 (Ginsenoside derivatives, in particular, dihydroxyxinenoside Rbi or Prevention, treatment, and treatment of suture failure due to epoxy ginsenoside Rb) Diabetics, the elderly, immunodeficiency patients, malnutrition patients, cancer patients, etc. often develop suture failure after surgery. Preventing this from happening is considered to be of paramount importance. Therefore, ginsenoside derivatives, particularly dihydroxyzine senoside R bi or epoxy ginsenoside R bi, are usually added at a dose of 0.001 mg or more per day, preferably before or after surgery. Intravenous single or continuous infusion at a dose of 0.1 mg or more, more preferably 1 mg or more, significantly reduces the rate of postoperative suture failure and accelerates the recovery of surgical wounds. Become. In addition to the intravenous infusion of ginsenoside derivatives, especially dihydroxyzinenoside Rb or epoxydinosenoside Rb, a water-soluble base, an ointment base, an ophthalmic base, a fat-soluble base An external preparation for the skin (cream, gel, poultice, spray, ointment, etc.) by mixing low concentration of dihydroxyzine senoside R bi or epoxy ginsenoside R b with any or known base such as A liquid or eye ointment may be prepared and applied or instilled at the surgical wound site and around the wound until the wound is healed. In addition, ginsenosides, in particular, dihydroxyzine senoside R b or epoxy ginsenoside R bi may be locally administered during the operation. At that time, the concentration of the extracellular solution of the ginsenoside derivative in the local part is 100 g / m 1 (about 90 M) or less, preferably 100 ng / 1 (about 90 nM) or less, more preferably Is less than or equal to Ing Zml (about 0.9 nM), more preferably less than or equal to 100 fg Zml (about 90 fM). Adjust the amount mixed in. That is, the amount of the ginsenoside derivative mixed into the external preparation for skin is preferably 0.1% by weight or less, more preferably 0.01% by weight or less. In the present example, dihydrozincenoside Rbi may be used as one of the ginsenoside derivatives. Example 8 (Treatment and treatment of radiation damage or burns caused by ginsenoside derivatives, especially dihydroxydine cenoside Rb or epoxy ginsenoside Rb) Extensive degeneration of the tissue and the failure to achieve satisfactory results with skin culture sheet transplantation can jeopardize the patient's prognosis. For such patients, skin tissue regeneration from transplanted skin sheets Ginsenoside derivatives, especially dihydroxy ginsenoside R bi or epoxy ginsenoside to promote the regeneration and reconstruction of lesions due to cell division and proliferation, migration to lesions, differentiation, and adhesion of healthy skin tissue constituent cells. Inject R bi at a dose of 0.001 mg or more, preferably 0.1 mg or more, more preferably 10 mg or more per day, or a single or continuous infusion into the vein every day until symptoms are improved. . Of course, ginsenoside derivatives, in particular, dihydroxyzine senoside Rb or epoxydinsenoside Rbi were injected intravenously, and ginsenoside derivatives, especially dihydroxyzine, were added to a water-soluble base or a fat-soluble base. Senoside R b! Or E port Kishijinsenosai de R b ₁ contaminating skin external agent (cream, gel, lotion down, cataplasms, sprays or ointments, etc.) to create a until skin lesions and lesions near its improvement • cured It may be applied. At that time, the extracellular fluid concentration of ginsenoside derivatives, especially dihydroxyxenosenoside Rb or epoxyginsenoside Rb, at the lesion site was 100 μg / m1 (about 90 μM). Or less, preferably 100 ng / m 1 or less (about 90 nM) or less, more preferably I ng Zm 1 (about 0.9 nM) or less, and still more preferably 100 fg / m 1 or less (about 9 nM). The amount of the dinzenoside derivatives, especially dihydroxyxenosenoside Rbi or epoxyzine senoside Rt ^, mixed into the base is adjusted so as to obtain 0 fM). Ginsenoside derivatives in external preparations for skin In particular, the concentration of dihydroxyxenosenoside R bi or epoxy ginsenoside R bi should be 0.1% by weight or less, preferably 0.01% by weight or less. Is preferred. If the radiation injury or burn is relatively mild, only the above-mentioned topical skin preparation may be administered. Of course, in the present embodiment, dihydrozincenoside Rbi may be used as one of the ginsenoside derivatives. Example 9 (Prevention, treatment, and treatment of pressure sores with ginsenoside derivatives, particularly dihydroxyxenineside R bi or epoxy ginsenoside R bi)

Among the diseases that cause impaired blood flow, bedridden wounds in bedridden patients and the elderly are skin diseases that can deteriorate the general state of the body and significantly impair the quality of life (QOL). Redness of the skin of the affected part is seen at the early stage of the pressure sore. The lack of intravenous formulations is a major problem in dermatology. Of course, it is often difficult to treat pressure sore lesions that have skin tissue defects. Ginsenoside derivatives, especially dihydroxyxenosenoside R bi or epoxy ginsenoside R bi, mixed with a water-soluble base or a fat-soluble base containing or not containing glucose , A poultice or a soft patch) and apply it constantly to the area of the pressure sore and its surroundings until the healing, reduction or deterioration of the sore. The concentration of ginsenoside derivatives, especially dihydroxyzinenoside Rb or epoxyzinsenoside Rbi, in the external preparation for skin should be 0.1% by weight or less, preferably 0.01% by weight or less. Is preferred. At that time, the extracellular concentration of the ginsenoside derivatives in the local area, in particular, dihydroxyzine senoside R bi or epoxy ginsenoside R b is 100 g / m 1 (about 90 M) or less, preferably 100 ng Zm1 (about 90 nM) or less, more preferably 1 ng / m1 (about 0.9 nM) or less, still more preferably 100 fgZml (about 90 fM) or less The amount of the ginsenoside derivatives, especially dihydroxy ginsenoside R bi or epoxy ginsenoside R b mixed into the base is adjusted so that In addition, if necessary, intravenous administration of ginsenoside derivatives, particularly dihydroxyzine senoside R bi or epoxy ginsenoside R bi as described in Example 7 and Example 8 I do. Ginsenoside derivatives such as dihydroxyzincenoside Rbt or epoxy ginsenoside Rbi, as described herein, inhibit the spread of pressure wound lesions through potent cytoprotection, It is thought that a superior therapeutic effect will be exerted on the depressed wound lesion in which skin tissue is deficient by promoting the regeneration and reconstruction of blood vessels or skin tissue. Of course, in the present embodiment, dihydrozincenoside Rb 丄 may be used as one of the ginsenoside derivatives. Example 10 (Treatment of Peptic Ulcer with Ginsenoside Derivatives, Especially Dihydroxyzine Senoside R b! Or Epoxy Ginsenoside R b ^)

As drug treatment means ulcer and duodenal ulcer, H ₂ receptor inhibitors, pro Tonpo pump inhibitor, although gastrointestinal mucosa protective agent is mainly used, temporarily by an agent Even if the ulcer lesion heals, the ulcer lesion often recurs when the drug is stopped. Ulcer lesions are also frequently seen in Crohn's disease and ulcerative colitis, which are designated as intractable diseases of the gastrointestinal tract, and worsen the prognosis of patients. After the onset of gastric ulcer, duodenal ulcer, ulcerative colitis, or Crohn's disease, apply ginsenoside derivatives as early as possible, especially with dihydroxyzine cenoside R bi or epoxy ginsenocyse, while applying usual treatment. Intravenous infusion of Rb, anal, vaginal, nasal administration, or external administration of mucosal lesions under an endoscope was performed, and the healing or improvement of the lesion was confirmed with an endoscope Treatment until continued. Of course, in the present embodiment, as one of Jinsenosai earth derivatives, may be used dihydrazide Dorojinsenosai de R b _1. Example 11 1 (Treatment of diabetic skin ulcer with ginsenoside derivatives, especially dihydroxyxenosenoside R bi or epoxy ginsenoside R b)

Diabetic skin ulcer is an intractable disease accompanied by impaired blood flow at the lesion and loss of skin tissue, etc., but ginsenoside derivatives, particularly dihydroxide, which have the effect of promoting the regeneration and reconstruction of blood vessels and skin tissue The effect can be obtained by intravenous administration, local injection or topical application of cyginsenoside R bi or epoxy ginsenoside R bt. That is, for patients with diabetic skin ulcer, ginsenoside derivatives, especially dihydroxyzine senoside R bi or epoxy ginsenoside R bi are usually added to the patient daily in addition to the usual treatment. A single or continuous infusion daily at a dose of OO lmg or more, preferably 0.1 mg or more, more preferably 10 mg or more. Also, if necessary, an external preparation for skin containing dihydroxyxenosenoside R bi or epoxy ginsenoside R bi may be applied to the lesion and its periphery as described in Example 8. Alternatively, a ginsenoside derivative, in particular, a physiological saline solution or a glucose solution of dihydroxyzinenoside R bi or epoxy ginsenoside R bt may be injected into a lesion site. At that time, the extracellular fluid concentration of the ginsenoside derivatives, particularly dihydroxyzine senoside Rbt or epoxyginsenoside Rb, in the lesion was 100 ^ g / m1 (about 90 M) or less. Preferably, it is not more than 10 Ong / 1 (about 90 nM), more preferably, it is not more than lng Zml (about 0.9 nM). The ginsenoside derivatives, particularly dihydroxy ginsenoside Rb or epoxy ginsenoside R, are preferably added to the base such that the concentration is 100 fg / m 1 (about 90 fM) or less. Adjust the amount of bi or the amount of local saline or glucose solution (dissolving agent) containing them. Of course, in the present embodiment, dihydroginsenoside R bi may be used as one of the ginsenoside derivatives. Example 1 2 (Induction of Bel—xi_ Expression in Neurons by Ginsenoside Rbt) Next, the present inventors found that ginsenosides (including ginsenoside derivatives) such as ginsenoside R bi by allowed to activate the transcription factor, cell death suppressing gene B e 1 - was investigated whether to induce the expression of x _L. As its reason First preliminary experiments, we choose the Jinsenosai de R bi behalf of Jinsenosai earths, whether Jinsenosai de R bt increases the expression of B c 1 one X _L gene of neurons Examined. The experimental procedure was based on the paper of the present inventors (Sakanaka, Tanaka) (Wen T.-, et al., J. Exp. Med., 188, 635-649, 1998). Cultured neurons pretreated with ginsenoside Rbt at 0 fg / 1, 1 fg / m1, lOOfg / ml and lOOOOfg / ml (100pg / m1) for 24 hours From 3 zg of DNase-treated total RNA from which total RNA was extracted, cDNA was generated using oligo dT primer and reverse transcriptase (Moloney murine leukemia virus reverse transcriptase). The gene amplification reaction (PCR) was performed using Taq polymerase under the following conditions. (1) 94 ° C, 2 minutes; (2) 94 ° C, 1.5 minutes; 55 ° C, 1.5 minutes; 72 ° C, 2 minutes as one cycle, and Bel— It is 25 cycles for xL, 20 cycles for / 3-actin, (3) 72 ° C for 2 minutes.

 The PCR product was run on a 3% agarose gel and visualized by ethidium bromide staining. The expression of mRNA of / 3-actin was used as an internal standard. The results are shown in FIG. Figure 14 is a photograph replacing the drawing.

In addition, in order to examine whether ginsenoside R bi enhances the expression of Be 1 — protein in neurons, a western blotting method was performed using an anti-Be 1 — x _L protein antibody. After culturing rat cerebral cortical neurons in the presence or absence of ginsenoside Rbi for 48 hours, the cells were lysed with a sample buffer for electrophoresis, and electrophoresis was performed. gave. Thereafter, the electrophoretic protein was transferred to a two-nitrocellulose membrane and subjected to Western blotting. The results are shown in FIG. Figure 15 is a photograph replacing the drawing.

Further, the band reacting with the anti-Be1— _xL protein antibody was quantified by an image analyzer, and the results are shown in FIG.

 As shown in Fig. 14, in cultured neurons treated with 1 fg / ml or 100 fg / ml of ginsenoside Rbt, the expression of Bc1-1 mRNA increased compared to the control. I was On the other hand, ginsenoside Rb significantly increased the expression of Be1-X protein in neurons by about 50% in the optimal concentration range of 1 to 100 fg / ml (Fig. 15, (Fig. 16). Example 13 (Activation of transcription factor STAT5 by ginsenoside Rbi)

Then the present inventors, through any transcription factor Jinsenosai de R bi, was examined whether promoting B el one X _L expression. For this reason, the following experiment was performed using an astrocyte, in which gene transfer was relatively easy. First, we created Bel—X Promo One Night and One Luciferase Zeplasmid. That is, DNA extracted from the tail tissue of C57BL / 6 mouse was designated as type III, and the following primers LF1, Primer LR1 and Pyrobest DNA polymerase (Takara) were used for 30 types. A cycle of the PCR reaction was performed. The reaction solution was purified using QiaExII Gel Extraction Kit (Qiagen), digested with restriction enzymes XhoI and HindIII, and electrophoresed on a 2% agarose gel. A bp DNA fragment was cut out. From the obtained gel slice, a DNA fragment was extracted using a QiaExII gel extraction kit (QiaExII Gel exraction kit) and inserted into pGL-2 Basic vector (Promega) (Betrox promoter L). ) (Fig. 17).

Similarly, using mouse DNA as type II, a PCR reaction of 15 cycles was performed using primers RF1 and RR1. The reaction solution was diluted 1000-fold (Solution A), and the resulting mixture was subjected to PCR for 30 cycles with Primer RF2 and Primer RR2 as type III, digested with Sacl and BamHI, pGL- 2 Basic vector was inserted into the SacI / BgIII site of the vector (Belt x promoter R) (No. 17 Figure).

 Further, the solution A was used as a type III, and a PCR reaction of 3'0 cycle was performed using each of the primer R F1 and the primer Mut-R, and the primer Mut-F and the primer R R1. Electrophoresis was performed on a 2% agarose gel, DNA fragments of 312 bp and 309 bp were cut out, and DNA fragments were extracted using a Qia EXII gel extraction kit (QiaExII Gel exraction kit). . The extracted DNA fragments are mixed at a weight ratio of 1: 1.

Perform PCR reaction of 30 cycles with RR2, digested with SacI and BamHI, and inserted into the Saccl / BglII site of PGL-2 Basic vector (Belt x promoter R (mutant (Fig. 17).

 The primary culture of the astrocyte was performed as follows.

 Astrocytes were isolated from a Wistar rat immediately after birth by a known method, cultured in a culture flask, and transplanted to a 12-well plate two weeks later. The astrosite was published by the present inventors (Sakanaka, Tanaka) (Fujita, H. et al., Glia, 18, 269-281, 1996; Ta aka, J. et al., Glia). , 20, 23-37, 1997; Tanaka, J. et al., Glia, 24, 198-215, 1998).

The gene transfer and Lucifera Zeattsey were performed as follows.

Transfection was performed for 5 hours in the presence of 10% FCS (fetal calf serum) using Lipofectamine (Invitrogen). Then change the medium Then, the cells were cultured at 37 ° C., and 100 fg / m 1 of ginsenoside Rb was added the next morning, followed by culturing at 37 ° C. for 24 hours. After washing the cell surface twice with PBS, the cells were lysed with Luciierase Cell Culture Lysis Reagent (Promega) 1001. The amount of luciferase in the solution was measured using a Luciferase Assaay System (Promega) and a Noreluminescence Sensor-J NR (AT TO).

 The results are shown in FIG. As shown in the first and second columns from the left in FIG. 18, even if ginsenoside Rbi was administered to an astrocyte transfected with Be1—X Promoter L, No change was observed in luciferase activity as compared with the control (ginsenoside Rbi-untreated example). On the other hand, as shown in the third and fourth columns from the left in FIG. 18, when ginsenoside Rb was administered to the outlet opening site where the Be 1 —X promoter-R was transfected, the control ( Luciferase activity was significantly increased as compared with ginsenoside R b (non-administered case). As shown in FIG. 17, a sequence similar to the STAT5 binding sequence exists in Be 1 —X promoter-R, but no such sequence exists in Be 1 —X promoter-L. Thus, the ginsenoside R bi is repotted by the activation of the transcription factor S TAT5 binding site located upstream of Exon 2 of the B c 1 —X gene, resulting in the recruitment of the gene Lucifera. It was thought that the activity was increased. On the other hand, as shown in the fifth and sixth columns from the left in Fig. 18, the mutant (with mutation) STAT5, ie, Bel—X promoter R containing STAT5m (mutant) (mutant) When ginsenoside Rb was administered after transfection of (Fig. 17) into an astrocyte, no change was observed in luciferase activity as compared to the control (ginsenoside Rbi-untreated example). (Fig. 18). ** in Fig. 18 indicates P <0.01, and the statistical analysis method is based on the Student's test.

From the above, the ginsenoside R t is activated through the activation of the transcription factor STAT5, which has a binding site upstream of exon 2 (Exon 2) of the Be 1 —X gene (Fig. 17). It can be said that it up-regulates the production of luciferase, one of the intergenes (Fig. 18). In this experiment, B e 1 - to X _L, measured easy repo Isseki - implementing the promoter mediation Si in a form of replacing the Gene (Lucifera Ichize) However, in this experiment, it was revealed that ginsenoside Rb promotes the expression of the Be1-X! _ Gene through activation of the transcription factor STAT5 in actual cells. Possibly, ginsenosides such as ginsenoside Rbi also increase the enzyme activity of JAK2, phosphorylating STAT5, and promoting homodimer formation and nuclear translocation of phosphorylated STAT5. It is thought to be. As a result, STAT5 is thought to function as a transcription factor. Example 14 (Stimulation of neuronal Bc1-1 protein expression by dihydrozincenoside Rb)

Then, the present inventors have dihydric Dorojinsenosai de R b ₁ is B c 1 in neurons - To examine XL mRNA not only B el- x _L whether to enhance expression of the protein, B e 1 - x _L antibody The Western blot method was performed using. Rat cerebral cortical neurons were cultured for 24 hours in the presence or absence of dihydrozine senoside Rbi, and the cells were lysed with a sample buffer for electrophoresis and electrophoresis was performed. Thereafter, the electrophoretic protein was transferred to a ditrocellulose membrane and subjected to Western blotting. For details of the experimental technique, see the papers already published by the present inventors (Sakanaka and Tanaka) (Wen T.-C., et al.,

 As shown in FIGS. 19 and 20, dihydrozincenoside Rbi significantly increased the expression level of Bc1-XL protein in neurons in the optimal concentration range of 1 to 100 fg / m1. Increased. * In FIGS. 19 and 20 indicates P <0.05, and the statistical analysis method is based on AN OVA + Fisher's PLSD.

From the above results, it can be said that ginsenoside derivatives such as dihydrozincenoside Rbi also enhance the expression of Bc1-XL in neurons similarly to ginsenoside Rbi. Moreover, as described in PCT / JP 00/055554, the pharmacological actions of dihydrozinsenoside R bi and ginsenoside R bi are extremely similar, so it is natural that dihydrozinsenoside R bt As well as ginsenoside Rb. It is thought that through activation of the transcription factor STAT5, Bcl-X expression in neurons is up-regulated. Example 15 (Promotion of VEGF mRNA expression of astrocytes by ginsenoside Rbt)
