[Objectives] To reveal the expression and potential mechanisms of PPARα and CPT-Ⅰ mRNA in liver of rats with nonalcoholic fatty liver disease induced by highly fat-enriched diet.[Methods] The model group(10 rats)was fed with highly fat-enriched diet while the normal control group(10 rats)was raised by standard animal feeds for 12 weeks.Hepatic lipid contents,plasma TG,CHO,HDL-C,LDL-C,ALT,AST and TNF-α,FFA concentrations were evaluated,as were histopathological changes in the liver and hepatic PPARα and CPT-...
