Hepatoprotective action of alcoholic extract of Bacopa monniera (BME) was evaluated on Dgalactosamine (D-GalN) induced rat liver toxicity. Bacopa monniera extract reduced the elevated serum enzyme activities of ALT, AST, ALP, LDH, ${\gamma}-GT$ and the formation of hepatic malondialdehyde induced by D-GalN. The alcholic extract of Bacopa monniera also significantly restored the decreased levels of glutathione and the decreased activities of glutathione peroxidase, glutathione reductase, superoxide dismutase, catalase and glucose-6-phosphatase. Therefore these results suggest that Bacopa monniera has hepatoprotective effect against D-GalN induced hepatotoxicity.

In order to investigate the protective effects of Jiyusaenggan-Tang by F-I(Jiyusaenggan-Tang aspirated by distilled water), F-II(Non-polysaccharides in Jiyusaenggan-Tang) and F-III(Polysaccharides in Jiyusaenggan-Tang), experimental studies were performed in mice with liver injury induced by $CCI_4$, and d-galactosamine. The results were summarized as follows : 1. The increases of the serum GOT activities in mice induced by $CCI_4$ were inhibited significantly by the administration of highly concentrated FIII. The increases of the serum GPT, LDH, and ALP activities in mice induced by $CCI_4$ were inhibited significantly by the administration of highly concentrated FI and FIII. 2. The increases of the serum total-cholesterol and triglyceride activities in mice induced by $CCI_4$ were inhibited significantly by the administration of highly concentrated FI, FII and FIII. 3. On liver injury induced by the $CCI_4$, the activities of GOT, GPT, ALP, LDH were inhibited by highly concentrated FIII, F-I, F-II, and F-I, F-II, F-III on total cholesterol level and F-III, F-I, F-II on triglyceride level in order of their efficacies. And F-III is considered to be the most effective component. 4. The increases of the serum GOT, GPT activities in mice induced by d-galactosamine were inhibited significantly by the administration of FI and FIII. The increases of the serum LDH, ALP activities in mice induced by d-galactosamine were inhibited significantly by the administration of FI and FIII. 5. The increases of the serum Total-cholesterol, Triglyceride activities in mice induced by d-galactosamine were inhibited significantly by the administration of FI, FII and FIII. 6. The increases of the serum GOT, GPT activities in mice induced by d-galactosamine were inhibited significantly in F-III administrated group and then F-I in order of efficacies. FII does not showed significant effect, on inhibiting the activities of serum GOT and GPT levels. The activity of ALP was inhibited by F-III, F-I, F-II, LDH by F-III, F-I in order of efficacies, and F-II did not showed significant effect on LDH activity. The triglyceride level was decreased significantly by F-III, F-II, F-I and the total cholesterol level by F-II, F-I, F-III in order of their efficacies. Judging from the above results, it is considered that Jiyusaenggan-Tang has protective effect against liver injury, and that Polysaccharides in Jiyusaenggan-Tang is more effective.

All animals were divided into 5 groups, those were normal group(untreated), control group(treated with vehicle 0.9% Saline solution), sample I group(10mg/kg administrated), sample II group(30mg/kg administrated), Silymarin 200 administrated group. The results were as follows: 1. The inhibitory effects of the serum GOT activities in rats induced by $CCl_4$ were noted in both sample I (p<0.001) and sample II group(p<0.001). In serum GPT activities, sample I (p<0.01) and sample II group(p<0.01). 2.

간기능 보호 작용이 있는 것으로 알려진 DDB, selenium과 glutathione의 혼합제제인 DWP-04의 간보호 작용을 검토할 목적으로 DWP-04를 실험동물에 경구로 투여하고서 D-galactosamine으로 간독성을 유발하여 혈액의 변동 및 간 조직에서의 활성산소 생성계 및 해독계의 활성에 미치는 영향을 관찰한 결과 GaIN의 단독투여는 대조군에 비하여 혈중 간 기능 지표효소 및 간 조직에서의 지질과산화의 함량이 현저히 증가하였으나, DWP-04의 전처리로 현저히 감소되었다. CaIN의 단독 투여로 활성산소의 생성계인 phase 1계의 효소가 현저히 증가하던 것이 DWP-04의 처리로 억제되었으며 해독계인 phase II계의 효소는 GaIN의 투여로 대조군에 비하여 억제되던 것이 DWP-04의 전처리로 정상군에는 미치지 않으나 유의성 있게 증가되었다. 간 조직중 glutathine의 함량은 CaIN의 투여로 현저히 억제되었으며 DWP-04의 투여로 증가하였는데 이러한 결과는 DWP-04의 투여로 glutathione peroxidase의 활성보다는 $\gamma-glutamylcysteine$ synthetase의 활성을 조절한 결과로 생각된다. 이상의 결과를 종합하여 볼 때 DWP-04의 투여는 활성산소의 생성 및 해독계를 조절하므로서 GaIN으로 인한 간손상을 보호하는 효과가 있는 것으로 사료된다.

본 연구는 D-galactosamine에 의해 간 손상이 유도된 흰쥐에 다슬기(Semisulcospira libertina) 추출물이 손상된 간세포의 개선 및 회복에 미치는 효과에 관해 조사하였다. 다슬기 추출물은 간 손상에 따른 간 조직 내 국소적 지방 변성과 염증세포 침윤을 크게 감소시켜 대조군과 유사한 수준으로 회복시키는 경향을 나타내었다. 또한 다슬기 추출물은 간 손상 지표 효소인 AST와 ALT, LDH 및 ALP의 증가된 효소 활성을 대조군 수준으로 완화시키며, 간 조직 내 지질과 과산화지질의 함량을 감소시켜 간 손상으로 인한 혈중 효소 활성과 조직 내 지질 함량을 개선하는 것으로 조사되었다. 이와 더불어 다슬기 추출물은 염증반응을 촉진시켜 조직상해 및 괴사를 유도하는 $TNF-{\alpha}$의 발현을 억제시키며, 염증 시 세포를 보호하는 HO-1의 발현을 촉진시켜 염증 반응에서 손상된 세포를 대조군 상태의 세포로 회복시키는데 관여하는 것으로 조사되었다. 따라서 다슬기 추출물은 간조직의 괴사 및 섬유화를 회복시키고 혈액 내 효소의 활성과 조직 내 지질 함량을 개선할 뿐만 아니라 염증 반응 인자의 발현을 조절하고 있어 간 손상으로 인한 간세포의 개선 및 회복에 효과가 높은 기능성 소재로서의 가능성을 제시해 주고있다.

In order to investigate the hepatoprotective constituents, Melonis Pedicellus was systematically extracted and fractionated with n-hexane, ethyl acetate, butanol and water Treatment of rats with ethyl acetate fraction reduced hepatic injuries induced by $\alpha$-naphthylisothiocyanate or D-galactosamine, whereas the components in water fraction showed protective effect only against D-galactosamine-induced hepatitis in rats. Two cucurbitacins and three sterols were isolated from ethylacetate fraction and their chemical structures were identified as cucurbitacin B, isocucurbitacin B, $\alpha$-spinasterol, stigmast-7-en-3-ol and stigmast-7-en-3-ol-0-$\beta$-D-glucopyranoside. Cucurbitacin B at the dose of 1 mg/kg (p.o.) signifcantly increased in bile flow in rats with ANIT-induced cholestasis. Isocucurbitacin B at 5 mg/hg (p.o.) showed signilicant protective effects against ANIT-induced cholestasis. These results showed that cucurbitacin B and isocucurbitacin B from Melonis Pedicellus may have hepatoprotective effect in rats with experimental cholestasis.

Objectives : This study was to examine the efficacy of GCT on the hepatoprotective effect in the liver function and immune octivity. Methods : The experiment to investigate the hepatoprotective effect of GCT on the liver damage was conducted with D-galactosamine. The experiments to verify the effects of GCT on the immune activity were conducted by carbon clearance assay, plaque-forming cell SRBC assay of IgM, lymphoproliferation assay of T and B cells, and adherence and phagocytosis of mocrophages. Results: In the damage of liver induced by D-galactosamine, GCT carried hepatoprotective effect on AST. In carbon clearance assay GCT showed significant effect on phagocytosis of Kuffer cells. In the plaque-forming cell assay, GCT improved the formation of IgM. In the lymphoproliferation assay, GCT activated the formation of T and B lymphocytes. In macrophages, GCT activated adherence and phagocytosis. Conclusion : Though further study is needed, our findings suggest that GCT could be recommended as hepatoprotector and immune modulator for liver disease.
