Objectives : We aimed to determine therapeutic effects of probiotics-fermented Magnolia denudata(MD) in the allergic rhinitis model mice. Methods : Polyphenol production, DPPH radical scavenging activity and NO inhibition of fermented MD by different bacterial strains were evaluated to select the one that is most suitable for fermentation. Thirty C57BL/6 mice were divided randomly into 5 groups as follows: normal group, ovalbumin(OVA)-treated plus water fed(CON group), OVA-treated plus unfermented MD fed(UMD group), OVA-treated plus fermented autoclaved MD fed(A-FMD group) and OVA-treated plus fermented unautoclaved MD fed(FMD group). After 9 weeks, we observed changes in the blood cell count, OVA-specific IgE level, nasal rubbing, nasal mucosal tissue and body weight. Results : Extract of MD fermented by Bifidobacterium breve(BB) for 48 hours showed the highest anti-oxidant activity and anti-inflammatory activity out of all the other bacterial strains. The number of eosinophil count in A-FMD, FMD group and platelet count in FMD group showed statistically significant decrease(p<0.05). OVA-specific IgE level decreased in all 3 experimental groups, significantly in UMD and A-FMD group. Nasal symptoms were attenuated in all 3 experimental groups, statistically significant in A-FMD and FMD group (p<0.05). Histologically, infiltration of eosinophils into the nasal mucosa decreased in all 3 experimental groups, especially marked decrease in FMD group. Conclusions : According to the above results, it is considered that probiotics-fermented Magnolia denudata has inhibitory effects on the allergic rhinitis animal models.

Cordyceps is a genus of ascomycete fungi and is well known as one of the important medical fungi in Chinese, Korea, and other Asian countries, because of its various beneficial effects on human health. The pharmacological activities of Cordyceps extract are mainly focused on anti-cancer, anti-metastatic, and immune modulating effects. In the present study, we investigated whether the antiplatelet effect of ethanol extract of cultured Cordyceps militaris (CMEE) with FeCl₃-induced arterial thrombosis model. We observed that CMEE exhibited a significant inhibitory effect against ADP and collagen-induced platelet aggregation. However, there were no significant differences in prothrombin time (PT) and activated partial thromboplastin time (aPTT). These results suggest that antithrombotic activity of CMEE is related to antiplatelet effect rather than anticoagulation effect, and CMEE may be a positive effect on improving blood circulation against vessel injury and occlusion.

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.

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 purpose of the study was to investigate the effects of dietary green tea catechin and vitamin E on the phospholipse {TEX}$A_{2}${/TEX} activity and th antioxidative defense system in streptozotocin (STZ)-induced diabetic rats. Sprague-Dawley male rats weighing 100$\pm$10 gm were randomly assigned to one normal and five STZ-induced diabetic groups. The diabetic groups were assigned either a catechin-free diet (DM group), 0.5% catechin diet (DM-0.5C group), 1% catechin diet (DM-1C group), vitamin E-free diet (DM-0E group), and 400 mg vitamin E per kg diet (DM-400E group) according to the levels of dietary catechin or vitamin E supplementation. The vitamin E levels of the normal, DM, DM-0.5C, and DM-1C groups were 40 mg per kg diet. Diabetes was experimentally induced by an intravenous injection of streptozotocin after 4 weeks of feeding the five experimental diets. The animals were sacrificed on the 6th day of he diabetic state. The body weight gains were lower in all five diabetic groups after the STZ injection. The platelet phospholipase {TEX}$A_{2}${/TEX}({TEX}$PLA_{2}${/TEX}) activity in the diabetic groups was higher than that in the normal group. However, the enzyme activity in the DM-0.5C, DM-1C, and DM-400E groups was lower than that in the DM and DM-0E groups. The cytochrome {TEX}$P_{450}${/TEX} and cytochrome {TEX}$b_{5}${/TEX} content and NADPH-cytochrome {TEX}$P_{450}${/TEX} reductase activity were about 50~110% higher in the DM and DM-0E groups than in the normal group, yet significantly reduced by either catechin or vitamin E supplementation. The superoxide dismutase (SOD) content in the liver did not differ significantly in any of the groups. However, the glutathione peroxidase (GSHpx) activity was generally lower in the diabetic groups, compared with the normal group, whereas that of the DM-0.5C, DM-1C, and DM-400E groups was significantly higher compared with that of the DM and DM-0E groups. The levels of thiobarbituric acid reactive substances (TBARS) in the liver tissue were 148% and 201% higher in the DM and DM-0E groups, respectively, compared with the normal group, however, these levels were reduced by either catechin or vitamin E supplementation (DM-0.5, DM-1C and DM-400E). Accordingly, the present results indicate that STZ-induced diabetic rats exhibited an imbalance between free radical generation and scavenger systems in the liver which led to the acceleration of lipid peroxidation. However, these abnormalities were reduced and the antioxidative defense system was restored by either dietary catechin or vitamin E supplementation. In conclusion, the effects of dietary catechin or vitamin E in streptozotocin-induced diabetic rats would appear to inhibit lipid peroxidation as an anti-oxidant by regulating the activity of {TEX}$PLA_{2}${/TEX}.

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.

In the present study, I have investigated the bee venom (BV) and melittin (a major component of BV) -mediated anti-proliferative effects, and defined its mechanisms of action in cultured rat aortic vascular smooth muscle cells (VSMCs). BV and melittin $(0.4{\sim}0.8\;{\mu}g/ml)$ effectively inhibited 50 ng/ml platelet derived growth factor BB (PDGF-BB)-induced VSMCs proliferations. The regulation of apoptosis has attracted much attention as a possible means of eliminating excessively proliferating VSMCs. In the present study, the treatment of BV and melittin strongly induced apoptosis of VSMCs. I examined the effects on $NF-{\kappa}B$ activation to investigate a possible mechanism for anti-proliferative effects of BV and melittin, the PDGF-BB-induced $I{\kappa}B{\alpha}$ phosphorylation and its degradation were potently inhibited by melittin, and DNA binding activity and nuclear translocation of $NF-{\kappa}B$ p50 subunit in response to the action of PDGF-BB were potently attenuated by melittin. In further investigations, melittin markedly inhibited the PDGF-BB-induced phosphorylation of Akt but not ERK1/2, upstream signals of $NF-{\kappa}B$. Treatment of melittin also potently induced pro-apoptotic protein p53, Bax, and caspase-3 expression, but decreased anti-apoptotic protein Bcl-2 expression. These results suggest that the anti-proliferative effects of BV and melittin in VSMCs through induction of apoptosis via suppressions of $NF-{\kappa}B$ and Akt activation, and enhancement of apoptotic signal pathway. Based on these results, BV acupuncture can be a candidate as a therapeutic method for restenosis and atherosclerosis.
