摘要
目的:探讨延肾胶囊抑制5/6肾切除大鼠残肾纤维化、延缓慢性肾衰竭的作用机制。方法:取健康Wistar大鼠30只,随机分成假手术对照组、手术组和延肾胶囊治疗组。采用生物化学、形态计量、免疫组化技术检测各组大鼠术后60 d肾功能、肾组织形态学、肾组织蛋白酶B(CB)和Ⅳ型胶原表达。结果:延肾胶囊治疗组比手术组血清肌酐、尿素氮水平明显下降,肾小球硬化程度明显减轻;免疫组化显示,治疗组比手术组大鼠CB表达增多,Ⅳ型胶原表达减少。结论:延肾胶囊可能通过促进CB表达增加,降解Ⅳ型胶原等细胞外基质而抑制5/6肾切除大鼠残肾组织纤维化。
Objective:To explore the effects and mechanism of Yanshen Capsule on the remnant kidney. Methods: Thirty healthy Wistar rats were randomly divided into 3 groups: control group rats were sham - operated and gavaged with saline daily, operation group rats were 5/6 nephrectomized and garaged with saline daily, treatment group rats were 5/6 nephrectomized and garaged with Yanshen Capsule daily. The body weight(BW), blood urea nitrogen(BUN) and ereatinine (Scr) levels, renal morphological changes, the expression of collagen Ⅳ (Col Ⅳ ) and cathepsin B (CB) were observed using biochemistry, morphometry and immunohistochemistry at 60 days after operation. Results: The BUN and Scr of Yanshen Capsule- treated group also slightly higher than that of control group, but were significantly lower than that of operation group(P 〈 0.01 ). In Yartshen Catxsule- treated group, lower ratio of sclerosis glomeruli, higher exprssion of CB and lower expression of Col Ⅳ were observed compared to that of operation group. Conelusion: Yanshen Capsule retards the development of renal fibrosis through increasing CB and suppressing Col Ⅳ.
