摘要 目的探讨糖尿病肾病大鼠肾组织中血红素氧合酶(HO-1)在糖尿病肾病病变中的变化和意义。方法建立STZ大鼠模型,将24只糖尿病模型大鼠分为干预组、5、10、15周组,每组各6只,另设健康对照组6只,分别检测各组大鼠体质量、血糖及尿24h白蛋白排泄率(UEA)的变化;采用免疫组化染色法标记HO-1蛋白的组织分布,观察其变化及肾组织的病理变化。结果糖尿病大鼠5、10、15周时和干预组的血糖及UEA均明显高于对照组(均P<0.05),干预组与糖尿病5周时比较UEA减少,但差异无统计学意义(P>0.05);随着病程的进展,肾组织中HO-1表达逐渐增强,HO-1的激动剂预处理可使HO-1表达显著增强,在糖尿病肾脏损伤前应用HO-1的激动剂UEA可降低。结论HO-1参与糖尿病肾病的发生、发展,HO-1的激动剂可延缓糖尿病肾病的进程。
