摘要 目的探讨TNF-α、MDA、AngⅡ对肾创伤的影响。方法选择健康成年普通级Wistar大鼠40只,随机分为5组:对照组8只、创伤组32只(分别于打击后1、6、12、24小时各处死8只)。采用自由落体打击仪直接打击大鼠脊肋区制作肾机械性创伤模型。放免分析法检测肾组织匀浆上清液TNF-α、AngⅡ浓度,比色法检测肾组织匀浆上清液MDA浓度:光学显微镜观察肾组织的变化,并通过Paler氏肾小管评分对肾创伤程度作出评价。结果创伤肾组织出现明显的形态学改变。肾创伤早期肾小管评分、肾组织匀浆AngⅡ及MDA浓度明显升高,与对照组有显著性差异(P〈0.05);急性创伤后期上述指标均逐渐降低,并接近正常时照组,比较无显著性差异(P〉0.05)。TNF—α浓度在急性创伤早期无明显改变,而于急性创伤后期(创伤后12小时和24小时)明显升高,比较有显著性差异(P〈0.05)。结论AngⅡ和MDA与肾创伤程度呈显著正相关,为导致肾组织损伤的有害因子;TNF—α与肾创伤程度呈显著负相关,为参与创伤修复的保护性因子。
