摘 要:Objective:To investigate the therapeutic effect of total iridoid glycosides of Picrorhiza scrophulariiflora(TIGP)on non-alcoholic steatohepatitis(NASH).Methods:SD rats were fed with high-fat and high-sugar diet for 8 weeks to establish *** were given orally at doses of 20,40 and 80 mg/kg/d for 4 *** assay(TG),total cholesterol(TC),low density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C),aspartate aminotransferase(AST),alanine aminotransferase(ALT),fasting plasma glucose(FPG),fasting insulin(FINS),tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),chemokine-1(MCP-1),leptin(LEP)in serum were ***,TC,superoxide dismutase(SOD),malondialdehyde(MDA),and free fatty acid(FFA)in liver tissue were determined by colorimetric *** of hepatocytes and inflammation was performed by pathological ***:The results showed that TIGP significantly decreased TC,TG and FFA in liver tissue,increased SOD activity,decreased MDA content,decreased serum levels of TG,TC,HDL-C/LDL-C,ALT,AST,GLU,HOMA-IR,TNF-αand LEP,and in addition,improved steatosis of liver cells compared to ***:TIGP had anti-fatty liver effect against NASH rats induced by high-fat and high-sugar *** mechanism was related to the regulation of lipid metabolism and reduction of insulin resistance,through inhibition of oxidative stress and inflammation.
