Abstract: 目的探讨尿毒清对慢性肾功能衰竭大鼠肾脏纤维化的影响。方法36只大鼠随机分为3组,正常对照组、手术对照组及尿毒清组。除正常对照组外,余均采用左侧肾脏切除加尾静脉重复注射阿霉素的方法制作慢性肾功能衰竭大鼠模型。术后1周正常对照组和手术对照组每天灌胃同体积生理盐水,尿毒清组给予尿毒清混悬液3g/(kg.d)灌胃,共给药8周。于第4、8周测量24h尿蛋白定量、肾功能,第8周光镜下观察肾脏病理变化,应用免疫组织化学SABC法测定肾组织α-平滑肌肌动蛋白(α-SMA)、胶原Ⅳ(COLIV)的表达。结果与正常对照组比较,手术对照组24h尿蛋白、血尿素氮(Bun)、血清肌酐(SCr)明显升高(P<0.01),肾组织α-SMA、COLIV的表达较高(P<0.01)。尿毒清组尿蛋白、Bun、Scr均较手术对照组明显下降,肾组织α-SMA和COLIV的表达低于手术对照组(P<0.01)。结论尿毒清可减少蛋白尿的排泄,改善肾功能,抑制肾小管上皮细胞表型转化,延缓肾脏纤维化。
