This study was done to investigate the effects of Artemisia selengensis methanol extract on ethanol-induced hepatotoxicty in rat liver. Sprague-Dawley(SD) rats weighing about 150g were divided into the following 4 groups : control group(CON), Astemisia selengensis methanol extract administered group(ASE), ethanol adminstered group(ETH) and Artemisia selengenis methanol extract and ethanol administered group(ASA). Ethanol and Artemisia selengenis methanol extract were administered orally by 5m1/kg and 200mg/kg body weight per day for 6weeks, respectively. Body weight, daily food intake and percent liver weight per body weight were significantly changed by ethanol administration in comparison to control group. The activities of serum alanine aminotransferase(ALT), asparate aminotransferase(AST), and hepatic TBA-reactants increased by ethanol were decreased significantly by Artemisia selengensis methanol extract compared with ethanol group. It was also obseued that superoxide dismutase, catalase and glutathione peroxidase were not changed by Artemisia selengensis methanol extract, whereas hepatic xanthine oxidase activity was inhibitied by Artemisia selengensis methanol extract as compared to ethanol group. The glutathione contents in liver decreased by ethanol adminstration, but glutathione levels increased in ASA compared with ethanol group. These results suggest that Artemisia selengenis methanol extract have a possible protective effect on the ethanol-induced hepatotoxicity in rat liver.
