摘要: 目的 探讨5/6肾切除(5/6NT)大鼠肾脏病理形态学动态变化。方法 通过5/6NT大鼠在不同的时间段对肾组织标本进行光镜及电镜检查,观察肾脏病理动态变化情况。结果 5/6NT大鼠肾脏病理变化为:第2周,肾小球增大,系膜细胞轻度增生,肾小管扩张;第8周,系膜重度增生,肾间质炎细胞浸润和增宽;第12周出现局灶节段性硬化的肾小球,肾间质轻度纤维化;第40周时,大部分肾小球纤维化、硬化,肾间质重度纤维化。结论 5/6肾切除模型符合人类肾纤维化的病理改变,是研究慢性肾衰竭、肾纤维化的理想动物模型。

Abstract: Objective To investigate the dynamic changes of renal pathological morphology in the rat model with 5/6 nephrectomy. Methods Observed by light and electron microscope. Results The characteristics of renal dynamic changes of 5/6 nephrectomy rat:glomenrulus enlarged ,mesangial cells hyperplasia and tubule expansion at 2 weeks. At 8 weeks, mesangial cells severe hyperplasia and tubule-interstitial inflammation and expansion.At 12 weeks,focal segmental glomerular sclerosis and renal interstitial fibrosis. At the last of 40 weeks, we could see most of glomerulus fibrosis and sclerosis and tubule-interstitial severe fibrosis. Conclusion The changes of 5/6 nephrectomy in rats were accorded with renal fibrosis in human, it was a ideal model to research in chronic renal failure and renal interstitial fibrosis.
