The aim of this meta-analysis was to systematically investigate the anti-hepatotoxic effect of ginseng in rats induced toxicity which damage to liver. Primary researches were gained on the ScienceDirect database, the DBpia, and the KISS, and the data about the effect factors in plasma and in enzyme were listed as many as possible. The effect factors were alanine transaminase (ALT), aspartate transaminase (AST), liver aminopyrine N-demethylase (AD), liver aniline hydroxylase (AH), liver 3,4-Methylenedioxyamphetamine (liver MDA), cytochrome P450 (P450), serum alkaline phosphatase (ALP), serum lactate dehydrogenase (LDH), cytochrome b5 (Cyto b5), glutathione reductase (GR), Liver glutathione S-transferase (GST), liver glutamyltransferase (GT), Liver (${\gamma}-GCS$), serum liver 3,4-Methylenedioxyamphetamine (serum MDA), serum sorbitol dehydrogenase (SDH), serum total protein (TP), serum ${\gamma}-glutamyltransferase$ (${\gamma}-GT$). To investigate the effect of ginseng, the mean difference (MD) between the group of rats induced by toxicity (RH) and the group of rats induced by toxicity with ginseng (RHG) were combined, and the significance of MDs were tested. The combined MDs were checked the biases caused by heterogeneity among studies and the publication biases, and adjusted by using random effect model and trim and fill method, respectively. The effect about ALT, AST, ALP, LDH, SDH, TP and ${\gamma}-GT$ in plasma factors were significant, and about AD, liver MDA, P450, Cyto b5, GR, GST, GT and ${\gamma}-GCS$ in enzyme factors were significant. The treatment with ginseng supplementation was significantly effected on plasma and enzyme factors of damaged-rats.

This study was performed to evaluate the effect of liver damage on toluene metabolism in rats pretreated with carbon tetachloride. Liver damage in rats was induced by administration of 0.1ml of carbon tetrachloride per 100g of body wight intraperitoneally every day for four weeks except the last day before sacrifice. One day before sacrifice, toluene was administered to the animals instead of carbon tetrachloride. Rats were sacrificed at the 1st, the 2nd, the 3rd and the 4th week after the first administration of carbon tetachloride. Based on the histopathological findings, liver weight and serum alanine aminotransferase, the $CCl_4$-preteated group was found to have gradual severe liver damage. Especially the degree of liver injury became increasingly severe throughout the whole course of the experiment. The contnts of hippuric acid in urine lower in the all groups pretreated with $CCl_4$than that of the control. The contents of hepatic cytochrome P450(CYP), benzylalcohol dehydrogenase and benzaldehyde dehydrogenase activities were decreased in $CCl_4$-pretreated rats than those of the control. The $CCl_4$treated animals showed the gradual decreased activities of these enzyme as injection times elapsed. Km values of the benzylalcohol dehydrogenase in pooled liver samples from $CCl_4$-pretreated or control groups were similar. On the other hand, Vmax values of the $CCl_4$-pretreated group was lower than of the control. Therefore, it can be concluded that reduction of the toluene metabolism in damaged rat liver induced with $CCl_4$was due to the inhibition of CYP content, bezylalcohol and benzaldehyde dehydrogenase activities which related with toluene metabolic enzyme system.

Distribution of radioactivity in the skin tissues, subcutaneous tissues, blood and body organs was examined following topical application of $^{125}I-rhEGF$(0.4 ${\mu}Ci$), in the form of a Pluronic F-127 gel, on the normal and damaged (burned and stripped) skins of SD male rats. The radioactivity in the skin tissues and subcutaneous tissues was 3-5 times higher for the damaged skins than for the normal skin. But pretreatment of the skin with rhEGF (1${\mu}g$)) twice at 24 hr dose intervals affected the distribution of the radioactivity yielding the order of burned skin> stripped skin=normal skin. The decrease for the stripped skin by the pretreatment might be related either to the pathophysiological change of the skin or to the down regulation of the EGF receptor. Liver showed the highest radioactivity in amount following single and multiple administration of the drug to the normal and damaged skins. But,in concentration, the kidney and stomach showed higher value than the liver which is consistent with that kidney is a major eliminating organ of EGF and that EGF exerts its pharmacological effect specifically for the stomach.

The effect of saponin extracted from Panax grneng CA Meyer on DNA repair and replicative DNA synthesis were examined in CHO-Kl cells cotreated with benzo(a)pyrene and rat liver S-15 fraction. The DNA strand breaks inititated by benzo(a)pyrene metabolites were measured by alkaline election technique. The addition of ginseng saponin to the culture media resulted in decrease of benzo(a)pyrene-induced DNA strand breaks, and restored the suppressed-semiconservative-DNA-synthesis by the carcinogen. DNA repair synthesis in the damaged cells was also elevated by the ginseng treatment when the repairing activites were measured for the (3H)-thymidine incorporation into the carcinogen damaged cellular DNk Comparative analysis of DNA-adduces of benzo(a)pyrene metabortes in microsomes suggested that ginseng saponin treatment in rats reduced the formation of electrophilic metabolites of benzo (a)-pyrene in the rat liver microsomes.

Objectives : This study was designed to investigate protective effects of Sayeoksanhap-Pyeongweisan-Gamiban(SPG) on hematological changes in rats damaged by CCl4 Methods : We investigated the effects of SPG on hematological changes in terms of AST/ALT levels, Total cholesterol, HDL-cholesterol and triglyceride in serum and lipid peroxidation in rat liver. Results : Administration of SPG decreased AST level in serum effectively. In addition, lipid peroxidation in liver tissue, which was elevated by injection of CCl4, was decreased by administration of SPG. In contrast, ALT level, Total cholesterol, HDL-cholesterol and triglyceride in serum were not affected by administration of SPG. Conclusion : These results suggest that oral administration of SPG was useful to protect liver against CCl4 by its antioxidant action in liver tissues.

The effect of aqua-acupuncture of total saponin on the recovery of liver function in -intoxicated rats was exemined. Rats were divided into normal, control and three experimental groups (As-I group : aqua-acupuncture of saline to Gansu locus and Aa-III group : aqua-a-cupuncture of total saponin to blank locus at the thigh). Changes of some serum biochemical parameters (ALT, AST and ALP, total protein and albumin, and albumin/globulin (A/G) ratio) were determined. Serum ALT activities were increased by $CCI_{4}$T and decreased in all aqua-acupuncture groups compared with the control group. Aa-I group showed significant decrease of ALT activities on the 2nd (P<0.05) and 3rd (P<0.05) day, respectively. Aa-II group showed significant decrease on the 3rd day (P<0.05) day. Serum AST activities were increased by $CCI_{4}$T and decreased in all apua-acupuncture groups compared with the control group. Aa-I group showed significant decrease on the 1st (P<0.05), 2nd (P<0.001) and 3rd (P<0.001) day, respectively. Aa-II group showed significant decrease on the 3rd (P<0.001) day. Aa-III group showed significant decrese on the 1st (P<0.05) and 3rd (P<0.001) day, respectrvely. Serum ALP activities were increased by $CCI_{4}$T and decreased in all aqua-a-cupuncture groups compared with the control group. Aa-I group showed significant decrease on the 3rd (P<0.01) day. Total protein, albumin and A/G ratio were decreased by $CCI_{4}$T and increased in all aqua-acupuncture groups compared with control group. Aa-I group showed significant increase only on the 3rd day in albumin (P<0.01). It was thought that the aqua-acupuncture of total saponin to Gansu locus was effective on the recovery of liver function in $CCI_{4}$T-intoxicated rats.

To investigate the cause of increased plasma catecholamine levels in liver disease, catechol-O-methyltransferase (COMT), which provides a major route of catabolism for circulating catecholamines, was studied under the cholestasis induced by mechanical biliary obstruction in rats. Monoamine oxidase (MAO) activity and the $K_m$ and $V_{max}$ values for both enzymes were also measured. Cytosolic, microsomal, and mitochondrial COMT activities in the cholestatic liver were significantly decreased throughout the experiment. Microsomal, and mitochondrial MAO activity in the cholestatic liver were also significantly decreased. Vmax values of COMT and MAO were lower. Serum COMT and MAO activities were detected after CBD ligation. These results indicate that plasma catecholamine levels are increased in liver disease due to decreased hepatic degradation of catecholamines by decreased activities of COMT and MAO. The decreased activity of these enzymes is caused by decreased biosynthesis and by flowage into the blood from the damaged hepatocyte.
