The purpose of this research was to investigate the effects of Kwakhyangjeonggisan (KJS) on the anti-allergic action. In the present study, we examined the effect of KJS on type I and type IV allergic reaction. KJS inhibited the systemic anaphylaxis induced by compound 48/80 and platelet activating factor (PAF), and inhibited the passive cutaneous anaphylaxis (PCA) induced by anti-dinitrophenyl (DNP)-IgE and DNP-human serum albumin (HSA) in vivo. In addition, KJS dose-dependently inhibited the release of histamine from peritoneal mast cells in rat. Also, KJS inhibited the delayed type hypersensitivity (DTH) induced by SRBC and the contact dermatitis induced by dinitrofluorobenzene (DNFB). KJS inhibited the proliferation of splenocytes, the subpopulation of B220+ cells and CD4+CD8-(Th) cells in splenocytes and the production of γ-interferon in serum and splenocytes. These findings suggest that KJS prevented the type I allergy by the inhibition of histamine release from mast cells and the type IV allergy by the inhibition of γ-interferon production and B lymphocytes subpopulation. These results indicate that KJS may be useful for the prevention and treatment of type I and type IV allergy related disease.

The purpose of this research was to investigate the effect of Kamidangkwieumja(KDEJ) water extract on the allergy reaction in mice. The results were obtained as follows: 1. The passive cutaneous anaphylaxis induced by egg albumin in fat was not affected. 2. The lethal anaphylaxis induced by platelet activating factor in mice. was inhibited. 3. The degranulation of peritoneal mast cells induced by compound 48/80 was not affected. 4. The acute hind paw edema was inhibited after 2hours later when it was induced by histamine. 5. The permeability of evans blue into peritoneal cavity induced by acetic acid was not affected. 6. Arthus reaction in mice was not affected. 7. The delayed type hypersensitivity induced by SRBC was inhibited. 8. The contact dermatitis induced by DNFB was not affected. 9. The hemagglutination titer induced by SRBC was inhibited. 10. The writhing syndrome induced by acetic acid was inhibited. 11. The population of heper T cells in mice thymus was enhanced. 12. The phagocytic activity of peritoneal macrophages was enhanced. 13. The production of nitric oxide from peritoneal macrophages was not affected. These results suggest that the anti-allergy effect of KDEJ is caused by steroidlike and enhanced immune action. The steroidlike action of KDEJ correspond with steroid-applying-method that frequently used in clinic, so it is used io treatment of psoriasis. The research on anti-allergy of KDEJ might has to be continued.

The thrombosis is the category of blood stasis. Blood stasis is a pathologicial state resulting from the reverse or impeded flow of blood in the body or the stagnation of blood flow in local parts as well as abnormal blood outside of the vessles which remains in the body and fails to disperse. Hwao-tang has been reported to have a hypolipidemic effect in patients with hypercholesterolemia, and in highcholesterol-induced experimental models. The present paper reports the effects of HOT on atherosclerosis using a spontaneous experimental model, Kurosawa and Kusanagi-hypercholesterolemic (KHC) rabbits. We have also investigated the pharmacological effect of extracts obtained from HOT on collagen-and ADP-induced blood platelet aggregation, thrombin-induced conversion of fibrinogen and fibrinolysis in in vitro experiments. In conclusion, the protection of extracts of Korean herbs' HOT on the ischemic infarction induced artificially might be involved to their inhibition of thrombotic action.

The present study was conducted to investigate the potential subacute toxicity of CKD-602 by a 5-day repeated intravenous administration in Sprague-Dawley rats. CKD-602 was administered intravenously to male rats at dose levels of 0, 0.08, 0.2, and 0.5 mg/kg for 5 days. Studies included general observation, body weight changes, ophthalmoscopic examination, hematology, se겨m biochemistry, gross findings at necropsy and organ weight measurement. There were no deaths in any treatment group and treatment related clinical sign was depilation in the 0.5 mg/kg groups. The decrease or suppression of body weight was also observed dose-dependently in all treatment groups. Decreased leukocyte in all treatment groups, decreased platelet in the above 0.2 mg/kg groups and increase in the serum levels of total cholesterol in the 0.5 mg/kg group were considered as a treatment related toxic effects. Decreased weight of thymus in all treatment groups anti decreased weight of spleen in the above 0.2 mg/kg group were observed. The intravenous administration of CKD-602 caused depilation and decreased weight and had toxic effect on the leukocyte, platelet, spleen and thymus. In the condition of this study, the target organs were spleen and thymus and the toxic effect level was determined to be 0.2 mg/kg, but no-observed-adverse-effect level (NOAEL) was considered to be lower than 0.08 mg/kg.

In this study, we investigated the effect of (-)-epigallocatechin-3-gallate (EGCG), a major component of green tea catechins from green tea leaves, on activities of cyclooxygenase (COX)-1 and thromboxane synthase (TXAS), thromboxane $A_2$ ($TXA_2$) production associated microsomal enzymes. EGCG inhibited COX-1 activity to 96.9%, and TXAS activity to 20% in platelet microsomal fraction having cytochrome c reductase (an endoplasmic reticulum marker enzyme) activity and expressing COX-1 (70 kDa) and TXAS (58 kDa) proteins. The inhibitory ratio of COX-1 to TXAS by EGCG was 4.8. These results mean that EGCG has a stronger selectivity in COX-1 inhibition than TXAS inhibition. In special, a nonsteroid anti-inflammatory drug aspirin, a COX-1 inhibitor, inhibited COX-1 activity by 11.3% at the same concentration ($50{\mu}M$) as EGCG that inhibited COX-1 activity to 96.9% as compared with that of control. This suggests that EGCG has a stronger effect than that of aspirin on inhibition of COX-1 activity. Accordingly, we demonstrate that EGCG might be used as a crucial tool for a strong negative regulator of COX-1/$TXA_2$ signaling pathway to inhibit thrombotic disease-associated platelet aggregation.

Spatholobus Suberectus dunn. has been applied to blood stasis in oriental medicine. We selected one potent ethyl acetate subfraction-2 from Spatholobus Suberectus Dunn.(SSD) from anti-metastasis screening. It exerted the cytotoxicity against HT1080 and B16BL6 with the IC50 of 60 ug/ml and also significantly inhibited tumor cell induced platelet aggregation (TCIPA). It effectively didn't inhibit cell adhesion of HT1080 to matrigel coated wells, while it inhibited the cell invasion of HT1080 at the doses of 10, 20, 40 μg/ml by Boyden chamber assay. It effectively suppressed lung metastasis by B16BL6 melanoma in C57BL6 mice. These results indicate that the EtOAc subfraction-2 of Spatholobus Suberectus Dunn. can be applied to caner treatment with anti-metastatic activity.

Background: Ginsenoside Rp1 (G-Rp1) is a novel ginsenoside derived from ginsenoside Rk1. This compound was reported to have anticancer, anti-platelet, and anti-inflammatory activities. In this study, we examined the molecular target of the antiproliferative and proapoptotic activities of G-Rp1. Methods: To examine the effects of G-Rp1, cell proliferation assays, propidium iodine staining, proteomic analysis by two-dimensional gel electrophoresis, immunoblotting analysis, and a knockdown strategy were used. Results: G-Rp1 dose-dependently suppressed the proliferation of colorectal cancer LoVo cells and increased their apoptosis. G-Rp1 markedly upregulated the protein level of apolipoprotein (Apo)-A1 in LoVo, SNU-407, DLD-1, SNU-638, AGS, KPL-4, and SK-BR-3 cells. The knockdown of Apo-A1 by its small-interfering RNA increased the levels of cleaved poly(ADP-ribose) polymerase and p53 and diminished the proliferation of LoVo cells. Conclusion: These results suggest that G-Rp1 may act as an anticancer agent by strongly inhibiting cell proliferation and enhancing apoptosis through upregulation of Apo-A1.

Idiopathic thrombocytopenic purpura(ITP) is characterized by the development of a specific anti-platelet autoantibody immune response mediating the development of thrombocytopenia. Systemic lupus erythematosus(SLE) is an autoimmune disease characterized by the production of a wide variety of autoantibodies. We experienced SLE patient whose initial symptoms were related to idiopathic thrombocytopenic purpura(ITP). She has a thrombocytopenia after Splenectomy and Steroid therapy on ITP and SLE. After she took Eight constitution Acupuncture treatment, thrombocytopenia has improved. We think Acupuncture will be effective treatment at autoimmune disease.

Objective : Yinjinchunggan-tang(YJCGT) is reported previously as having theraputic effects on hepatitis such as anti-implammatory, anti-apoptotic, anti-viral(HBV), etc. Though this prescription is not studied on its anti-fibrogenic effect, it is still expected to have the effect in the liver. Thus, this study was performed to investigate the anti-fibrogenic effect of YJCGT on thioacetamide(TAA)-induced liver fibrosis in rats. Method: Rat liver fibrosis was induced by intraperitoneal TAA injection(150mg/kg) 3 times a week for 5 weeks. After the YJCGT (YJCGT 1g/kg, YJCGT 2g/kg)-treatment, body weight, liver and spleen weights, liver function test, the complete blood count and the portal pressure were studied. In addition, gene expressions of ASMA, procollagen type Ia2, MMP2, TIMP1 and TIMP2, all of which are known to be associated with liver fibrosis, were analyzed by RT-PCR. After YJCGT (YJCGT 1g/kg, YJCGT 2g/kg) treatment, percentages of collagen in TAA-induced rat liver tissue were measured by image analyzer. Results : The body weight of the normal group increased more than that of the control and YJCGT-treated groups. The AST level of the YJCGT lg/kg-treated group significantly decreased compared to that of the control. The ALT and the GGT levels of the YJCGT 2g/kg-treated group significantly increased compared to those of the control. In the YJCGT-treated groups. WBC, RBC and Hgb elevated by TAA injection decreased but platelet count increased. In the YJCGT lg/kg-treated group, the portal pressure elevated by TAA injection significantly decreased. The significant decreases in the gene expressions of procollagen type Ia2, MMP2 and TIMP2 were observed in the YJCGT-treated groups. In histological findings. TAA injections caused severe liver fibrosis, but the YJCGT treatment significantly reduced the amounts of hepatic collagens. Conclusions: These results suggest that YJCGT has beneficial effects on the treatment of patients with liver cirrhosis as well as chronic hepatitis. Further study should be done to decide the optimal concentration of the YJCGT for the treatment of liver cirrhosis.
