OBJECTIVE: To investigate the therapeutic effect of emodin on nonalcoholic fatty liver (NAFL) induced by high fat diet in rats.
METHODS: NAFL model was established by feeding with high fat diet for 12 weeks in 40 SD rats, confirmed by liver pathologic examination, which were randomly divided into 5 groups: the model control group the mere dietary treatment group (both with distilled water by gastrgarege), the low, moderate and high dose emodin groups treated with emodin 20,40 and 80 mg x kg(-1) x d(-1) once per day respectively. Meanwhile a normal control group was used. The model control group was still fed with high fat diet while the other groups with normal diet. After 4 weeks, body weight, liver index (liver weight/body weight), hepatic function, blood lipid, hepatic lipid and histologic changes were assayed.
RESULTS: In the model control group,body weight, liver index, hepatic enzyme activities, serum lipid and hepatic triglyceride increased significantly (P <0. 05, or P <0. 01), serum high density lipoprotein-cholesterol( HDL-C)decreased (P <0.01 ), and moderate to severe hepatocyte steatosis was observed, while these indexes were all improved significantly in the 3 emodin groups; hepatic histologic changes were improved in the mere dietary treatment group, however, high level of ALT and hyperlipidemia persisted.
CONCLUSION: Emodin combined with dietary therapy is effective for NAFL rats induced by high fat diet.
