Abstract
目的 探讨大黄有效成分大黄素甲醚对急性肝损伤的保护作用.方法 以2 ml/kg体质量四氯化碳(CCl4)灌服雄性Wistar大鼠3 d诱导急性肝损伤动物模型,观察大黄素甲醚对实验性肝损伤大鼠血清酶含量、血清肿瘤坏死因子(TNF)水平及肝组织病理学改变的影响.结果 大黄素甲醚组与模型组相比,血清酶学指标[ALT(U/L):(670.3±42.0)vs(917.1±78.0),AST(U/L):(1 157.2±86.2)vs(2 701.4±108.4)]及TNF水平明显降低[(1.6±0.3)μg/L vs(2.1±0.4)μg/L](均P＜0.05).大黄素甲醚组肝组织病理改变较模型组明显减轻.结论 大黄素甲醚对大鼠急性肝损伤具有保护作用。
