In order to investigate the protective effect of Samduhaejungtang-gamibang on the liver injury of rats induced by $CCl_4$ and d-galactosamine, the serum transaminase(GOT& GPT) alkaline phosphatase(ALP), lactic dehydrogenase(LDH) for enzyme activities and triglyceride, total bilirubin amounts for serum component were measured. All animals were divided into 4 groups, those were normal group(untreated), control group(treated with vehicle 0.9% Saline solution), sample Ⅰ group(1500mg/kg administrated), sample Ⅱ group(3000mg/kg administrated). The results were as follows: 1. The inhibitory effects of the serum GOT activities in rats induced by $CCl_4$ were noted in sample Ⅱ group(p<0.01). In serum GPT activities, sample Ⅱ group(p<0.05) only showed the inhibitory effects. 2. The inhibitory effects of the serum ALP activities in rats induced by $CCl_4$ were noted in sample Ⅱ group(p<0.01) 3. The inhibitory effects of the serum LPH activities in rats induced by $CCl_4$ were noted in sample Ⅱ group, but it is not recognized statistically. 4. The increases effects of the serum triglyceride content level in rats induced by $CCl_4$ were inhibited in both sample Ⅰ group(p<0.05) and sample Ⅱ group(p<0.01) 5. The increases effects of the serum total bilirubin content level in rats induced by $CCl_4$ were inhibited in sample Ⅱ group(p<0.05) 6. The inhibitory effects of the serum GOT, GPT activities in rats induced by d-galactosamine were noted in sample Ⅱ group (p<0.001), but sample Ⅰ group was not recognized. 7. The signiticantly inhibitory effects of in the serum LDH activities in rats induced by d-galactosamine were noted in both sample Ⅰ group(p<0.05) and sample Ⅱ group (p<0.001) 8. The increases of the serum ALP content level in rats induced by d-galactosamine were inhibited in sample Ⅱ group(p<0.05) 9. The increases of the serum total bilirubin content level in rats induced d-galactosamine were inhibited in sample Ⅱgroup(p<0.05) According to the above results, it is considered that Samduhaejungtang-gamibang has protective effect against liver injury in rats induced by $CCl_4$ and d-galactosamine. So it is required to study about the actions of mutual relation of medicines and patho-mechanism by experiment.

In this study the effects of water extracts of endocarps and seeds of omija(Schizandra chinensis Baillon)on alcohol metabolism in rats were investigated. 25% alcoholic solution(v/v,0.75g/200g B.W.)and 40% alcoholic solution(v/v,0.80g/200g B.W.)were orally administered to rats for 2 hours. The levels of metabolites and enzyme activities both on serum and liver were not changed by acute oral adminiatration of 25% and 40% alcoholic solution. Blood alcohol levels were significantly lowered by treatment of water extracts of endocarps and seeds of omija in rats administered with 25% and 40% alcohol. In 25% alcohol treated group, serum GPT level was decreased but hepatic G-6-P DH and pyruvate levels were increased. In 40% alcohol treated group, water extracts of endocarps and seeds of omija resulted in a significant decreased in serum levels of FFA, GPT but increased in serum glucose level. Hepatic levels of cytosolic protein, glycogen and pyruvate were increased by water extracts of omija parts in 40% alcohol treated group.

This study is to find out the antioxidative effect and serum and liver lipid composition of wild grape juice in vivo. Forty 6-week-old white Sprague Dawley rats were divided into 4 groups such as normal lipid group, normal lipid group with wild grape juice, oxidized lipid (basic diet plus 10% of oxidative lipid) group and oxidized lipid group with wild grape juice, and 2ml juice was provided everyday. After 4 weeks of feeding with experimental diet each groups were examined for the antioxidant enzyme activity in blood and liver microsome and their serum and liver lipid composition. Glutanthione peroxidase activity in blood was significantly higher in oxidized lipid group with wild grape juice than in oxidized lipid group. Glutanthione peroxidase activity showed no difference depending on wild grape juice supplementation. Glutanthione peroxidase activity in liver was significantly higher in the groups with wild grape juice than in the groups supplemented only with oxidized lipid. Glutanthione reductase activity showed no difference depending on the supplementation of wild grape juice. Serum triglyceride level in the group supplemented with oxidized lipid diet and wild grape juice showed similar value to the normal lipid group and the normal lipid group with wild grape juiceoxidized fa6. Liver total lipid in the group supplemented with oxidized lipid and wild grape juice showed similar value to the normal lipid group and the group supplemented with normal lipid and wild grape juice. And it was lower than that of oxidative lipid group without juice. The liver triglyceride level in the group supplemented with normal lipid and wild grape juice was lower than that in the oxidative lipid group, but it was as low as in the group supplemented only with normal lipid.

Effect of chitosan oligo saccharides (COS) on the level of serum lipids, antioxidant enzyme activities and lipid peroxidation was investigated in rats fed with high cholesterol diet for 4 weeks, The rats were divided into three experimental groups that is, high cholesterol diet group (0.5% cholesterol; control). high cholesterol diet and 1.0% or 2.0% COS-supplemented groups (COS I , COS II). Serum total cholesterol, LDL-cholesterol and triglyceride level were significantly decreased and relative HDL-cholesterol level in total cholesterol significantly increased in COS II group. Liver TBARS level and activities of SOD and catalase of COS I were also significantly reduced. These results suggest that supplement of chitosan oligosaccharides reduce levels of serum cholesterol and reduce oxidative damage by activating hepatic antioxidative defense system in rats fed with high cholesterol diets.

To evaluate the role of xanthine oxidase in liver damage by CCl4, a group of rats were fed tungstate for a month, which suppressed the activities of xanthine oxidase in serum and liver. Control group of rats were fed standard diet without tungstate. Liver damage was induced both in tungstate fed and control groups by two intraperitoneal injections of CCl4 at the level of 0.1ml/100g body weight at intervals of 24 hours. Increases in the levels of serum alanine aminotransferase by CCl4 were significantly smaller in tungstate fed rats than in control rats. Concomitantly, histopathologic changes were less in tungstate fed rats than in control ones. In rats either treated with CCl4 or not, hepatic type O xanthine oxidase activities were remarkably reduced by tungstate feeding. Hepatic aniline hydroxylase activities were higher in rats fed tungstate than control rats when animals were not treated with CCl4, but the enzyme activities were lower in tungstate fed rats than control when they were treated with CCl4. Neither tungstate feeding nor CCl4 treatment caused any significant changes in hepatic glutathione contents, and activities of hepatic glutathione S-transferase, glutathione peroxidase and superoxide dismutase. It is concluded xanthine oxidase reaction augment CCl4 induced liver damage via oxygen free radical system.

Objectives : The aim of this study was to investigate effects of the Sungjuchunggan-tang(Xingjiuqinggan-tang), which has been used for alcoholic diseases in Oriental medicine, on alcoholic metabolism and alcoholic liver damage. Methods : We evaluated the activities of alcohol dehydrogenase(ADH)and aldehyde dehydrogenase(ALDH), and measured the levels of AST, ALT, glucose, triglyceride, HDL-cholesterol, LDL-cholesterol and phospholipid in serum of guinea pigs. Results and Conclusions : In this experiment, Sungjuchunggan-tang, Pharbitidis Semen and Puerariae Radix significantly suppressed the activity of ADH which is a precursor enzyme of acetaldehyde. Sungjuchunggan-tang and Pharbitidis Semen significantly suppressed the activity of ALDH, which is a catabolic enzyme, and increased its level. Due to alcohol consumption, level of ALT and AST were significantly reduced. These experimental results suggest that Sungjuchunggan-tang and Pharbitidis Semen inhibit the formation of acetaldehyde in the metabolism of alcohol, and affect the recovery of weakened liver functions caused by alcohol.

In this study, we investgated the effect of Red Ginseng (KRG) on liver damage induced by carbon tetrachloride (CTC) and galactosamine (GalN) in rats using indicator enzymes such as serum alanine/aspartate aminotransferases, sorbital dehydrogenase, lactate dehydrogenase, and ${\gamma}$-glutamyltransferase. Treatment of KRG restored these enzyme activities to near normal level compared to CTC or GalN treatment alone. Treatment of KRG also enhanced hepatic microsomal enzyme system, malondialdehyde formation, and depletion of reduced glutathione content, which were reduced by CTC or GalN. We also found that the decreased activities of glutathione S-transferase and glutathine reductase but not ${\gamma}$-glutamycysteine synthetase after KRG treatment restored to normal level. These results indicate that KRG has potent therapeutic activity against CTC- and GalN-induced hepatotoxicity in rat.

Objective: To investigate whether the expression of serum soluble neural cell adhesion molecule (sNCAM) is associated with hepatic encephalopathy (HE) in hepatocelular carcinoma (HCC) patients. Materials and Methods: The Oncomine Cancer Microarray database was used to determine the clinical relevance of NCAM expression in different kinds of human cancers. Sera from 75 HCC cases enrolled in this study were assessed for expression of sNCAM by enzyme linked immunosorbent assay (ELISA). Results: Dependent on the Oncomine Cancer Microarray database analysis, NCAM was down regulated in 10 different kinds of cancer, like bladder cancer, brain and central nervous system cancer, while up-regulated in lung cancer, uterine corpus leiomyoma and sarcoma, compared to normal groups. Puzzlingly, NCAM expression demonstrated no significant difference between normal and HCC groups. However, we found by quantitative ELISA that the level of sNCAM in sera from HCC patients with HE ($347.4{\pm}151.9ng/ml$) was significantly more up-regulated than that in HCC patients without HE ($260.3{\pm}104.2ng/ml$), the p-value being 0.008. sNCAM may be an important risk factor of HE in HCC patients, the correlation coefficients was 0.278 (P<0.05) on rank correlation analysis. Conclusions: This study highlights that up-regulated level of serum sNCAM is associated with HE in HCC patients and suggests that the high expression can be used as an indicator.

The effects of intra-peritoneal injection of inorganic mercury on haemato-logical parameters and hepatic oxidative stress enzyme activities were studied in common carp, Cyprinus carpio. The fish were injected thrice intra-peritoneally with mercuric chloride TEX>$(5,\;10mg\;Hg\;kg\;b.W.^{-1})$. After exposure of three different mercury concentrations a physiological stress response was exerted on C. carpio by causing changes in the blood status such as erythropenia in blood and oxidative stress in liver. Red blood cell counts, hemoglobin concentration and hematocrit level were reduced in most cases by inorganic mercury. Remarkable low level of serum chloride, calcium and osmolality were also observed in the mercury- exposed fish. However, serum magnesium and phosphate were not altered by exposure to mercury. An increased activity of hepatic glutathione peroxidase was observed in the lowest treatment group of carp $(1mg\;Hg\;mg\;b.w.^{-1})$, hence, hepatic catalase and glutathione peroxidase of carp exposed to higher concentration of mercury $(5,\;10mg\;Hg\;kg\;b.W.^{-1})$ showed significant reduction in such activities.
