Effect of Er Chen Tang on CYP2E1 and Mitochondrial Energy Metabolism in Nonalcoholic Fatty Liver Disease / 中国药师

ABSTRACT

Objective:To observe the effect of Er Chen Tang on CYP2E1 and mitochondrial energy metabolism in nonalcoholic fat-ty liver disease ( NAFLD) to explore the role of Pinellinae Rhizoma Praeparata ( PRP) and Citri reticulatae pericarpium ( CRP) in the treatment of nonalcoholic fatty liver disease. Methods:Er ChenTang and the prescription without PRP or CRP was respectively given the animal models by gastric gavage. The serum levels of ALT, AST, triglyceride, cholesterol, SOD and MDA in hepatic tissue, and the contents of liver tissue CYP2E1 and ATP were detected in the mice. Results:The CYP2E1 levels in NAFLD mice increased signif-icantly with abnormal mitochondrial energy metabolism. Compared with those in the model group, the levels of ALT, AST, triglyceride and cholesterol were significantly reduced by Er Chen Tang, meanwhile, the content of CYP2E1 was reduced and also restored liver en-ergy metabolism. The treatment effect significantly decreased when the lack of PRP or CRP, and the ability of restoring liver mitochon-drial energy metabolism of Er Chen Tang decreased significantly when the lack of PRP (P<0. 05). After the removal of CRP, the in-hibition ability of Er Chen Tang to CYP2E1 levels significantly decreased (P<0. 05). Conclusion:Er Chen Tang can effectively im-prove nonalcoholic fatty liver diseases, and effectively reduce the content of CYP2E1 in liver tissue of mice and restore the mitochondri-al energy metabolism.
