摘要 目的探讨辑淫羊藿总黄酮对大鼠心肌急性缺血再灌注损伤氧化应激干预机制。方法选择72只8M大鼠,雌雄各半,体质量250 g-300 g,采用冠状动脉结扎法诱导大鼠心肌缺血再灌注模型,将大鼠随机分为假手术组、模型组、淫羊藿总黄酮小剂量组(10 mg/kg)和淫羊藿总黄酮大剂量组(20 mg/kg)共4组,每组18只;给药240 min后,采集大鼠腹主动脉血样,分离血清,测定SOD和MDA指标。结果模型组SOD显著低于假手术组,MDA显著高于假手术组,差异显著(P<0.05);淫羊藿总黄酮小剂量组和淫羊藿总黄酮大剂量组SOD均显著高于模型组,MDA显著低于模型组,差异显著(P<0.05);淫羊藿总黄酮大剂量组SOD均显著高于淫羊藿总黄酮小剂量组,MDA显著低于淫羊藿总黄酮小剂量组,差异显著(P<0.05)。结论淫羊藿总黄酮有助于减轻和改善大鼠心肌急性缺血再灌注损伤引发的氧化应激反应。
