Background: A previous study has shown that Euonymus alatus (EA) has an antidotic activities against inflammation, suggesting possibility that EA can exert this beneficial effects to liver injury by an initial protection against drug-induced hepatocyte demage. The present study was undertaken to evaluate the protective effect of EA-extract on experimentally induced hepatitis in ICR mice and to investigate some mechanisms responsible for its action. Methods: Water EA extract was used in this experiments. The mice received i.p. a dose of 700 mg/kg galactosamine (GalN) together with $5{\mu}g/kg$ of endotoxin (LPS), or received i.v. 12 mg/kg of concanavalin A (Con A). EA (4 mg/mouse) was administrated on day -2, -1 and 0 before induction of liver injury. Liver injury was assessed by measurement of serum alanin amino-transferase (SGPT) levels on 9 hr after GaIN.LPS, or 8 hr after con A administration. Results: Treatment with either GaIN or LPS alone did not cause hepatitis. However, simultaneous administration of GalN and LPS to mice resulted in LPS-dose dependent fulminant hepatitis. GaLN/LPS-induced liver injury was reduced when mice were given EA for 3 days before induction. This preventive effect of Ea was more prominent when EA was given by intraperitoneal route rather then by oral route. Pretreatment of EA or dexamethasone inhibited significantly $TNF{\alpha}$ production in GalL/LPS-injured mice. However, EA-treatment did not influence $TNF{\alpha}$-induced hepatitis in GalN-sensitized mice, suggesting that $TNF{\alpha}$ is likely to act as one of final mediators of endotoxin action and the protective effect of EA might be manifested chiefly by inhibition of endotoxin-induced $TNF{\alpha}$ production, not by blocking the $TNF{\alpha}$-action. Injection of Con A into mice evoked remarkable liver injury in a dose dependent fashion. This liver damage was reduced by EA-pretreatment. Dexamethasone significantly reduced both GalL/LPS-induced and Con A-induced liver damages, showing synergism with EA. However, indomethacin reduced only GalN/ LPS-induced hepatitis, not for Con A-induced hepatitis. Conclusion: These results led to the conclusion that EA may be able to contribute at least in part to prevent the drug-induced hepatotoxicity, and that its anti-hepatitis effects might be manifested directly by modulation of endogenous mediators, such as leukotriese D4, $TNF{\alpha}$ and free radical, and indirectly by regulation of immune mediated responses. Also these results suggested that EA could be developed as a potential antidotic agent.

The present study was carried out to investigate the pretreatment of effects of water extract obtained from Eucommia ulmoides leaf (ELE) on hepatotoxicity of carbon tetrachloride ($CCl_4$) -treated rats. Thirty two healthy male Sprague-Dawley rats were divided into four groups, i.e. normal group (N), $CCl_4$-treated group (T), ELE-treated group (E), and ELE-treated group after injection of $CCl_4$(TE). The administration of $CCl_4$increased the activities of aspartate aminotransferase, alanine aminotransferase and lactate dehydrogenase in serum, but their activities were significantly decreased by the addition of ELE. Alkaline phosphatase activity in serum was significantly decreased in $CCl_4$-treated group, while the activity was not decreased by the extracts. Higher levels of HDL cholesterol was found in E and TE group which showed lower levels of total and LDL-cholesterol. Histopathologic findings by light microscopic examination showed fatty change, ballooning degeneration, acidophilic degeneration, spotty necrosis and zonal necrosis in $CCl_4$treated liver tissue. But the degree of liver damage was not identified in liver tissue of the TE group. These results indicated that Eucommia ulmoides leaf water extracts led migtigation of liver demage induced with $CCl_4$.

The study was done to investigate the effects of the extracts from the different parts of Lythrum salicaria (LS) on liver protective activities in chronically alcohol-treated rats. SD male rats except normal animals were administrated with alcohol ($30m{\ell}$ of 30%~40% ethanol/kg/day) and the extracts (300 mg/kg/day) for 10 weeks. Chronic alcohol administration decreased body weight, high density lipoprotein (HDL)-cholesterol and the reduced form-glutathione (GSH), whereas increased the ethanol content, glutamic-oxaloacetic transaminase (GOT), total cholesterol, low density lipoprotein (LDL)- cholesterol, triglyceride in blood/serum and the ratio of the oxidized form of glutathione (GSSG) and total GSH (GSSG/total GSH) in liver tissue. Groups treated with the extracts of leaf, root and stem, showed decrease in GOT, total cholesterol and GSSG/total GSH and increase in hepatic aldehyde dehydrogenase (ALDH), total GSH and serum albumin. Administration with the root extract of LS decreased blood ethanol content compared with the other part extracts. But, serum triglyceride values in rats treated with root and stem extract were higher than that of the negative control animals. Flower extract-fed group showed decrease in body weight and serum triglyceride, but increase in the ratio of GOT and glutamic-pyruvic transaminase (GPT), and GSSG/total GSH. From the results, we conclude that the extracts of root and leaf among the plant parts of LS might be useful for the amelioration of the chronic alcohol-induced liver demage of rat.

This study was designed to investigate the effects of Korean 1% Shanshuyu extract in Pb administered rats. Forty male Sprague-Dawley rats weighed 100 l0g were used for this experiment and divided into following 4 groups; Con(control group), Shan(1% Shanshuyu extract), Pb(1,000ppm alone lead administered group), Pb-Shan(1,000ppm alone lead administered group with 1% Shanshuyu extract group). Food intake weight and FER(Food efficiency ratio) were remarkably decreased in lead added group. Tissue weight of liver, lung, stomach, heart, kidney and spleen of lead exposed rats were reduced by 1% Shanshuyu extract group. The lead content in the rats tissue of lead alone administered group was lower than in the rats tissue of lead administered group with 1% Shanshuyu extract group. AST(Asparatate transferase) and ALT(Alanine transferase) were increased in lead-administered group and lower in the 1% Shanshuyu extract group. These results suggested that 1% Shanshuyu extract may have some protective effects from of tissue demage induce with Lead.

The therapeutic effect of tissue cultured root of mountain ginseng (Panax ginseng) (tcMG) on 2,3,7,8-tetrachlorodaibenzo-p-dioxin (TCDD) induced toxicity in rat was investigated. The rats were assigned into three groups (10 rats/group), control, TCDD exposed group and tcMG treated group after TCDD exposed. $50\;{\mu}g/kg$ of TCDD was injected by i.p. for TCDD exposed group and 30 mg/kg of tcMG saponin was administered for 4 weeks by oral gavage for tcMG treated group. The weights of body, spleen, kidney, thymus, testes and epididymides were decreased in the single TCDD treatment. However these organs was significantly recovered by tcMG saponin except thymus (p<0.05). tcMG decreased the level of hepatic demage maker enzymes, AST and ALP. It also lowered total cholesterol and triglyceride. The level of serum triglyceride was significantly decreased in tcMG saponin treated group compared with the control. Histopathological examination revealed morphological change in the liver spleen, thymus and testes of TCDD treated rats. However they were relatively well preserved in the tcMG treatment group. In conclusion, TCDD induced toxicity was some repaired by tcMG. tcMG may be useful for prevention and treatment of TCDD induced toxicity.
