【摘要】 目的 研究肝素对缺血再灌流肾损伤的作用。方法 将18只家兔随机均分为手术对照组,单纯缺血再灌流(IR)组和肝素处理(IR-肝素)组,分别观察1h再灌注96h血清中尿素氮(BUN)的含量,尿中尿蛋白含量,肾组织中乳酸脱氢酶(LDH)活力和一氧化氮(NO)含量以及光镜下组织结构改变。结果 光镜下,对照组结构正常,IR组可见缺血坏死改变,IR-肝素组损伤改变轻于IR组;IR组同对照组比较,BNU、尿蛋白和NO含量明显升高,LDH活力明显降低(P<0.05,以下同);IR-肝素组同IR组比较,BNU、尿蛋白和NO含量明显降低,LDH活力明显升高,与对照组无明显差异(P>0.05)。结论 肝素对缺血再灌流肾损伤有一定的保护作用。关键词 肝素 肾 缺血 再灌流损伤
