To prevent human body injury from oxidative stress, antioxidants are very important and many research about antioxidants are generally being conducted. Hydrogen peroxide$(H_20_2)$ that is one of vitality oxygen species has been seen that cause various diseases, DNA damage and gene change. We have already known that the inhibition effect of Zizania latifolia Radix, Rhizoma on apoptosis induced by $H_2O_2$ in Neuro2A cell. And the purpose of this study was that we made a comparative study on the inhibition effect of apoptosis in Neuro2A cell on the region of Zizania latifolia(Radix, Rhizoma, Herba). Neuro2A cells were cultivated in RPMI(GibcoBRL) with 5% FBS and treated with $H_2O_2$ and Zizania latifolia(Radix, Rhizoma, Herba). Separately we measured the cell viability and analyzed DNA fragmentation. Activity of PARP, Cytochrome C, caspase-9, caspase-3, p53, p21, Bax and Bcl-2 in the cell was examined by using western blot. The results obtained were as Follows: The cell viability in all of Zizania latifolia (Radix, Rhizoma, Herba) treatment (60ug/m1<) decreased significantly compared with that of none treatment(p<0.001). Zizania latifolia Radix increased cell viability was most effective of three regions. But we had no significant difference among three regions. All of Zizania latifolia (Radix, Rhizoma, Herba) increased cell viability about twice as much as that being injury by $H_2O_2$,(Zizania Latifolia (Radix, nhizoma, Herba) 20ug/m1, $H_2O_2$ 200uM, p<0.001). DNA fragmentation developed by $H_2O_2$, but was not developed in all of Zizania latifolia (Radix, Rhizoma, Herba) treatment. PARP, Cytochrome C, caspase-9 and caspase-3 activated all by $H_2O_2$ but were not activated in all of Zizania latifolia (Radix, Rhizoma, Herba) treatment. P53, P2l and Bax activated by $H_2O_2$, and Bcl-2 got into inactivation. But the opposite results appeared in all of Zizania latifolia (Radix, Rhizoma, Herba) treatment. In conclusion, these results suggest that all of Zizania latifolia (Radix, Rhizoma, Herba) inhibit the development of DNA fragmentation and apoptosis by $H_2O_2$and the antioridant action of all of Zizania latifolia (Radix, Rhizoma, Herba) is effective.

This study was undertaken to define the effect of Polygoni cuspidatae Radix on contracted rabbit common carotid artery and its mechanism. In order to investigate the effect of Polygoni cuspidatae Radix on rabbit's contracted vascular ring detached from common carotid artery, vascular ring with intact or damaged endothelium was used for the experiment using organ bath. To analyze the mechanism of Polygoni cuspidatae Radix-induced relaxation, Polygoni cuspidatae Radix extract was infused into contracted vascular ring which had been pretreated by $N{\omega}-nitro-L-arginine(L-NNA)$, Methylene blue(MB), and $Ca^{2+}$ was infused into contracted vascular ring induced by NE or KCl after treatment of Polygoni cuspidatae Radix extract in $Ca^{2+}-free$ solution. The results were as follows : Polygini cuspidatae Radix had an effective relaxation to the contracted vascular ring by NE in 0.1 mg/ml and 0.3 mg/ml level. Polygini cuspidatae Radix had an effective relaxation to the intact endothelium vascular ring, but when endothelium was removed, vascular ring did not relax. Polygini cuspidatae Radix-induced relaxation was inhibited by the pretreatment of L-NNA and MB. Pretreatment of Polygini cuspidatae Radix extract inhibit the contraction by influx of $extra-Ca^{2+}$ in contracted vascular ring induced by NE or KCl in $Ca^{2+}-free$ solution. As mentioned above, we suggest that Polygini cuspidatae Radix relaxes vascular ring through suppress influx of extra-cellular $Ca^{2+}$ by the action of nitric oxide from endothelium.

생지황을 구증구폭하여 제조한 숙지황은 품질관리를 위한 지표물질이 아직 명확히 밝혀져 있지 않다. 생지황, 건지황과 숙지황을 methanol로 추출하고 ether, butanol, 수층으로 용매 분획하고 각 분획별로 TLC로 성분분석한 결과 ether층에서 숙지황의 특이성분이 나타났고, ether층을 증발농축하고 chloroform/methanol을 이동상으로 한 silica gel column으로 분리하고 다시 chloroform/methanol/물(7:1:1)의 preparative TLC로 단리하여 이 성분이 5-(hydroxymethyl)-2-furancarboxaldehyde(5-HMF)임이 규명되었다. 5-HMF는 생지황과 건지황에서는 숙지황에 비해 극히 미량이 존재하였다.

This research is the basic research to develop new anti-inflammatory medicine by feeding Scutellariae Radix extract to lipopolysaccharide(LPS) exposed rats, and analyzed it's effect on inflammatory response by LPS derivation. As a result, Plasma interleukin-$1\beta(IL-1\beta)$ and Plasma interleukin-6(IL-6) concentration showed the highest point at 5h after LPS injection, and in this time, the concentration of $IL-1\beta$ and IL-6 in the Scutellariae Radix extract groups at 200mg/kg and 300mg/kg showed lower values than that of control group. Plasma tumor necrosis $factor-\alpha(TNF-\alpha)$ concentration after LPS injection showed the highest point at 2h and showed similar level till at 5h. $TNF-\alpha$ concentration at 2h after LPS injection showed the low value only in the Scutellariae Radix extract 300mg/kg group compared to others, and in 5h, the all Scutellariae Radix extract groups showed lower value than that of the control group. Plasma interleukin-10(IL-10) concentration increased at 2h after LPS injection and reached the highest at 5h. After LPS injection the IL-10 concentration at 2h, the Scutellariae Radix extract injection group at 300mg/kg showed higher value than that of the others, and in 5h after LPS injection, Scutellariae Radix extract 200mg and 300mg groups showed higher value than the control group. Concluding from the above results, in inflammatory response by LPS derivation, the Scutellariae Radix gives positive effect.

The purpose of this research was to investigate cytotoxity of Sunbanhwalmyungeum extract. Cytotoxity was determined by MTT assay method. After tumor cell lines(G361, BI6F10, MDA, A549) transplantation, the extracts of SunBangHwalMyungEum and its composition oriental medicines were administered, cytotoxity was measured by absorbance. The results were obtained as follows. 1. Sunbanhwalmyungeum extract and its composition oriental medicines extracts showed the concentration was higher, the more cytotoxity increased. 2. Both water and ethanol extracts of Sunbanhwalmyungeum showed excellent cytotoxity against G361, B16F10, MDA, A549 and high cytotoxity over 80$\%$ against G361, B16F10, MDA except A549 at the concentration of 1000ppm. 3.

Object : This study was carried out to examine the effect of Bupleuri Radix on experimental cholestasis, and make clear apart of this mechanism. Methods : Two models of common bile duct ligation group and taurocholate load group after common bile duct ligation were induced, and Bupleuri Radix extract was taken orally for 14 days. In the 1, 2, 4, 7 and 14 days after treatment, the mitochondrial and microsomal monoamine oxidase(MAO) A and B activities in liver were measured. Results : The mitochondrial MAO A and B activities increased in both Blupleuri Radix treated group after common bile duct ligation and Blupleuri Radix treated group after taurocholate load and common bile duct ligation. MAO A increased in Blupleuri Radix treated group after taurocholate load and common bile duct ligation, and MAO B increased in Blupleuri Radix treated group after common bile duct ligation. The microsomal MAO A activities increased in both Blupleuri Radix treated group after common bile duct ligation and Blupleuri Radix treated group after taurocholate load and common bile duct ligation. Conclusion : According to the result, it is consider that Blupleuri Radix not only improves cholestatis in liver, but also decreases a genetic synthesis of taurocholic acid.
