METHODS： A quail model with hyperlipidemic fatty liver and rat model with alcoholic fatty liver were set up by feeding high fat diet and alcohol, respectively. These experimental animals were then treated with osthole 5-20 mg/kg for 6 wk, respectively. Whereafter, the lipid in serum and hepatic tissue, and coefficient of hepatic weight were measured. RESULTS： After treatment with osthole the levels of serum total cholesterol （TC）, triglyceride （TG）, lower density lipoprotein-cholesterol （LDL-C）, coefficient of hepatic weight, and the hepatic tissue contents of TC and TG were significantly decreased. The activity of superoxide dismutase （SOD） in liver was improved. In alcohol-induced fatty liver rats, the level of malondialdehyde （MDA） in liver was decreased. In high fat-induced fatty liver quails, glutathione peroxidase （GSH-PX） in liver was significantly improved. The histological evaluation of liver specimens demonstrated that the osthole dramatically decreased lipid accumulation. CONCLUSION： These results suggested that osthole had therapeutic effects on both alcohol and high fatinduced fatty liver. The mechanism might be associated with its antioxidation.展开更多
