To compare the efficacy of Stephaniae Tetrandrae Rhizoma and Sinomenii Caulis which are medicinal plants used as Bang Kee(防己), the plants were combined with Astragali Radix and Lycopii Herba into 6 different medicinal decoctions. The specimen decoctions prepared were each decoctions of Stephaniae Tetrandrae Rhizoma(St), Sinomenii Caulis(Si), Stephaniae Tetrandrae Rhizoma-Astragali Radix(StA), Stephaniae Tetrandrae Rhizoma-Lycopii Herba(StL), Sinomenii Caulis-Astragali Radix(SiA) and Sinomenii Caulis-Lycopii Herba(SiL). They were dosed to rats with induced hyperlipidemia. In the groups of rats with hyperlipidemia induced by high cholesterol diet, in the group which St was dosed to, there was no significant effect on the level of Tc, TG, HDLc. And in the group which Si was dosed to, the level of Tc, TG dropped and that of HDLc rose. In the groups of rats with hyperlipidemia induced by high cholesterol diet, in the group which StA was dosed to, there was no significant change in the level of Tc, TG, or HDLc. But in the group which SiA was dosed to, the level of Tc and TG dropped and that of HDLc rose. In the groups of rats with hyperlipidemia induced by high cholesterol diet, in the group which StL was dosed to, the level of TG dropped, but there was no significant change in the level of Tc or HDLc. And in the SiL group, there was no significant change in the level of Tc or TG, but the level of HDLc rose. On diseases such as hyperlipidemia, when using drug couple of Bang Kee-Astragali Radix as a treatment, Sinomenii Caulis is recommended rather than Stephaniae Tetrandrae Rhizoma, and when using drug couple of Bang Kee-Lycopii Herba as a treatment, Sinomenii Caulis and Stephaniae Tetrandrae Rhizoma neither showed significant effect. And as Lycopii Herba interrupts the effect of Sinomenii Caulis, drug couple of Sinomenii Caulis-Lycopii Herba is not recommended.

For the evaluation of the effect on SWS, experiments were made on hyperlipidemia induced by hypercholesterol diet, inhibitory reaction to human platelet aggregation, Pulmonary thrombosis induced by collagen and epinephrine, global cerebral ischemia induced by KCN, brain ischemia induced by MCA occlusion, cytotoxicity of PC12 cells induced by amyloid ${\beta}$ protein(25-35), and NO production in RAW cells stimulated by lipopolysaccharide. The results were obtained as follows : 1. In the experiment on hyperlipidemia, the level of serum total cholesterol, phospholipid, and LDL-cholesterol were significantly decreased while the level of triglyceride, VLDL-cholesterol, and HDL-cholesterol had no significant change. 2. In the experiment on inhibitory reaction to platelet aggregation, SWS inhibited platelet aggregation induced by ADP(36.05%), by collagen(20.4%), and by thrombin(0.6%). 3. In the experiment on pulmonary thrombosis induced by collagen and epinephrine, the protective effect was found(37%). 4. In the experiment on global cerebral ischemia, coma duration induced by KCN changed insignificantly. 5. In the experiment on MCA occlusion, the change of neurologic grades on hind limb was significant only after the operation. Besides brain ischemic area and edema ratio were significantly decreased. 6. In the experiment on cytotoxicity of PC 12 cells induced by amyloid ${\beta}$ protein, the significant protective effect was found as concentration increases. 7. In the experiment on NO production in RAW cells stimulated by lipopolysaccharide, NO was significantly decreased. According to the results, it is expected that SWS might be effective on hyperlipidemia and brain damage.

Rosae laevigatae Fructus extract (RLF) was tested for the effects on the urethral nitric oxide synthase (NOS) activity and Antioxidation in streptozotocin (STZ) induced diabetic rats. RLF was treated firstly into samples, and then STZ induced diabetic rats were set with them. In vitro, the urethral NOS activity was not noted but the type O activity and type conversion ratio of xanthine oxidase and the level of urethral lipid peroxide were decreased in the level of Dose of extract prepared from RLF. In vivo, after the extract was administered to the animal model for fifteen days, the urethral NOS activity increased in STZ induced diabetic rats to the level of normal rats. The content of urethral nitrite and glutathione followed by RLF pre-medicating administration, increased as highly as normal group in compare with the group treated with STZ. The type O activity and type conversion ratio of xanthine oxidase and the level of urethral lipid peroxide followed by RLF pre-medicating administration, decreased as lowly as normal group in compare with the group treated with STZ. In conclusion, the extract of RLF will be able to restore erectile dysfunction of STZ induced diabetic rats.

Objective and Methods : This study was performed to evaluate the anticonvulsant, antioxidant effect of modified formulas Korean traditional medicine Cheongsinhwadam-Jeon(CSHDJ). The extract of CSHDJ was administered (p.o.) to mice for 14 days in anticonvulsant and antioxidant tests. Results : The pretreatment of CSHDJ extract prohibited pentylenetrazol (PTZ)-induced convulsion. In PTZ-induced convulsion, lowered level of brain ${\gamma}$-aminobutyric acid(GABA) was restored normal state by the pretreatment of CSHDJ. Increased level of brain glutamic acid was lowered to normal state by CSHDJ, and increased activity of brain ${\gamma}-aminobutyric$ acid transaminase(GABA-T) was reduced to normal state by CSHDJ. In PTZ-induced convulsion, increased level of brain lipid peroxide was lowered to normal state by the pretreatment of CSHDJ. Increased activity of brain xanthine oxidase(XOD) was lowered by CSHDJ, and increased activity of brain aldehyde oxidase lowered to normal state by CSHDJ. In PTZ-induced convulsion, increased activities of superoxide dismutase(SOD) and catalase in brain were lowered by the pretreatment of CSHDJ, whereas increased level of glutathione and increased activity of gluthathione peroxidase in brain were not changed significantly. Conclusions : Above results suggest that CSHDJ has anticonvulsant, antioxidant effect. That seems to be strongly related with the levels of GABA, glutamate, lipid peroxide and the activities of GABA-T, XOD, aldehyde oxidase, SOD, catalase in brain tissue. From these results, CSHDJ could be applied to various convulsive disorders.

Objectives : This study was carried out to research the protective effects of Sagunja-Tang(SA) through in vivo experiments, and tried to investigate the relation between oxidation of liver tissues and deficiency of Qi. Methods : Acute liver injury which initiated from free radical induced by $CCl_4$, were applied to mice and metabolic data were obtained. In order to measure the degree of liver injury, serum level of alanine aminotransferase(AST), aspartate aminotransferase(ALT), creatinine, blood urea nitrogen(BUN), total protein(TP) and glucose were measured. Lipid peroxidation of liver slice was examined by measuring malondialdehyde(MDA), a product of lipid peroxidation. Results : SA had protective effects on $CCl_4$ induced acute liver injury by decreasing serum level of ALT. Kidney injury was induced by injection of $CCl_4$ too, and SA protected kidney injury by decreasing serum level of creatinine and BUN. Conclusions : Through this study, we found that SA have healing effects on liver and kidney injury of $CCl_4$ induced oxidative stress that is similar to deficiency of Qi. And further studies have to be followed to certify the mechanisms.

In this paper, field measurements in the subway tunnel and adjacent building were performed to predict the pound vibration level induced by urban rapid transit (subway) in Seoul, Korea. From the results of the measurements, the measured ground vibration level induced by subway in Seoul is smaller than the empirical formula of New York, but it is bigger than the empirical formula of Tokyo which has been commonly used in Korea. We suggested the empirical formula for prediction of ground vibration level induced by subway in Seoul considering on the wave propagation path for soils or rocks, respectively.
