An animal model of alcoholic fatty liver and the prevention and treatment with New Qinggan Decoction / 中西医结合学报

ABSTRACT

OBJECTIVE: To establish an animal model of alcoholic fatty liver (AFL) and to observe the prevention and treatment with New Qinggan Decoction (NQGD). METHODS: Female SD rats were exposed to the mixture of white spirit and corn oil continuously for up to 6 weeks via an intragastric feeding protocol. The pathologic alteration of the liver and the changes of serum lipid were observed, and the effect of NQGD for preventing and treating AFL was studied. RESULTS: Wide hepatic steatosis was induced in model group rats. Serum triglyceride (TG) and total cholesterol (TC) of the model group were higher than those of the normal group (P<0.01). Serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) of the model group were higher than those of the normal group (P<0.05). In NQGD group, hepatic steatosis was milder than that in the model group, and serum TG, TC, AST, ALT descended significantly as compared with the model group (P<0.01). CONCLUSION: AFL model of rats established by feeding the mixture of white spirit and corn oil is similar to the episode of the human AFL, and is easy to intervene with medicine. NQGD can prevent the occurrence of AFL in this model.
