摘要 【目的】观察氯沙坦对慢性移植肾病模型F344-Lewis大鼠移植肾功能、组织学和TGF-β_1的表达的影响。【方法】建立大鼠慢性移植肾病模型,随机分成氯沙坦组、单纯肾移植组。以切除单侧肾脏F344大鼠和Lewis大鼠为对照组。术后12周测定各组大鼠体质量、尾动脉血压、24 h尿蛋白定量、血清肌酐。行HE,Masson染色观察各组肾组织学改变。免疫组织化学染色检测肾组织TGF-β_1的表达。【结果】单纯肾移植组在肾移植后12周出现蛋白尿增多,血肌酐、血压升高,移植肾组织单个核细胞浸润及TGF-β_1表达上调。氯沙坦组较单纯肾移植组蛋白尿减轻,血肌酐、血压降低,移植肾组织单个核细胞浸润减少,TGF-β_1表达下调。【结论】移植术后早期给予氯沙坦可减轻慢性移植肾肾病进展,下调TGF-β_1表达。
