【摘要】Objective To study the effects of soybean isoflavone on liver lipid,serum lipid,antioxidant index and hepatic lipid metabolism associated factors in nonalcoholic fatty liver rats.Methods Thirty-six male rats(SD)were randomly divided into four groups by weight: normal control group,nonalcoholic fatty liver disease(NAFLD) model control group,low-dose isoflavone treatment group (10 mg/kg)and high-dose isoflavone group(20 mg/kg),9 rats in each group.Normal control rats were fed with D12450B(10% fat energy),model control and isoflavone intervention rats were fed with D12492(60út energy).Twelve weeks later,liver lipid,serum lipid and antioxidant index were observed.Liver sterol regulatory element binding protein-1 c(SREBP-1 c),fatty acid synthase(FAS)and
