摘要 目的:研究大黄酸对大鼠非酒精性脂肪肝(NAFLD)的防治作用。方法:60只SD大鼠随机分为:正常对照组、模型组、大黄酸低、中、高剂量(100,200,400 mg/kg)组。给药4周后,计算大鼠肝脏指数,观察肝组织病理形态学变化,试剂盒检测血清中ALT、AST、FFA、LDL-C、HDL-C、TG和TC的含量;测定肝组织中MDA、GSH-PX水平;Real-Time PCR检测肝脏组织中PPAR-γmRNA的表达。结果:大黄酸给药4周后,与模型组比较,大鼠肝组织脂肪变性明显减轻,肝脏系数明显降低;各给药组降低血清中ALT、AST、FFA、MDA、TG和TC的含量,升高GSH-PX、HDL-C含量(P<0.05或P<0.01);模型组PPAR-γmRNA的表达明显升高(P<0.01),大黄酸干预组明显降低PPAR-γmRNA的表达(P<0.01)。结论:大黄酸对大鼠NAFLD具有较好的治疗作用,与其清除氧自由基、减少脂质过氧化反应产物、减少炎症反应、改善脂质代谢紊乱有关。
