METHODS: The rat models of NAFLD were established with high-fat diet (HFD) for 10 weeks. Thirty-two rats were randomly divided into 4 groups: the control group, the model group, the decoction group and the solution group, 8 for each group. From the 6th week, drinking water, the decoction and the solution were intragastrically administrated accordingly to the rats for 5 weeks. The pathological changes of the liver tissues were observed with Hematoxylin and eosin staining, triglyceride levels in liver tissues measured, serum alanine aminotransferase (ALT) activity measured, and serum gastrin and motilin tested. RESULTS: Fatty degeneration and vacuole-like changes to various degrees occurred in hepaticcells of the model group. Indicators for fat metabolism, serum ALT activity and hepatic triglyceride level significantly increased, while serum gastrin and motilin levels significantly decreased. Serum ALT activity and the fatty deposition in hepatocytes were significantly reduced. In the meantime, the expressions of gastrin and motilin in the serum rose significantly in the treatment groups. CONCLUSION: Both the decoction and the extracts-mixed solution had effect on NAFLD of protecting the liver function and reducing the fatty deposition in liver, which might be achieved by regulating the expression of gastrin and motilin.展开更多
