摘要 目的观察白藜芦醇对脓毒症大鼠急性肝损伤的保护作用。方法40只SD大鼠随机分为假手术组(10只)和造模组(30只),造模大鼠术后随机分为脓毒症模型组和白藜芦醇干预组,每组15只,干预组尾静脉注射无菌白藜芦醇(40 mg/kg),其余尾静脉注射等量生理盐水。ELISA法检测TBil、AST、ALT、TNF-α和IL-6表达。Western blot检测肝组织细胞核P65的表达。结果造模前三组TBil、AST、ALT、TNF-α和IL-6表达水平无显著性差异(P>0.05),造模24h后假手术组TBil、AST、ALT、TNF-α和IL-6无显著性变化(P>0.05),而白藜芦醇干预组TBil、AST、ALT、TNF-α和IL-6表达显著低于脓毒症模型组(P<0.01)。肝组织细胞核P65相对灰度值在假手术组、脓毒症模型组和白藜芦醇干预组为0.22±0.05、0.48±0.11、0.34±0.07,各组间具有显著性差异(P<0.01)。结论白藜芦醇下调了脓毒症大鼠肝组织细胞核P65蛋白的表达,抑制炎症反应,对肝损伤具有保护作用。
