RESUMEN
Lotus leaf (LL) is one of the traditional Chinese herbs which can be used for both pharmaceutical and food application, and it posses lipid regulating efficacy. To observe the effect of LL on experimental nonalcoholic fatty liver disease (NAFLD) and its potential mechanism, a NAFLD model was established by feeding SD rat with high-fat and high-glucose diet. LL was administrated to rats in experiment group at the same time. AST,ALT,Cr,BUN,GLU levels in serum were determined by automatic biochemical analyser and TNF-α,IL-6,INS,ADPN,LEP and liver NF-κB,TGF-β1 levels were determined by ELISA according to the specification of the kits. HE staining was applied for histopathological examination and RT-PCR,Western blot was applied for AdipoR2 mRNA and protein expression．Results have shown that LL could significantly decrease ALT,AST,IL-6 level in serum and NF-κB,TGF-β1 level in liver,promote adiponectin content in serum and AdipoR2 protein expression in liver and could alleviate hepatocyte lipid degeneration. These results indicating that LL has protective effect for NAFLD induced by high-fat and high-glucose diet via promoting AdipoR2 expression, improving insulin resistance and inhibiting inflammatory reaction.
