【摘要】 目的 :观察肾炎益气液对肾毒血清性肾炎大鼠肾功能及肾组织学变化的影响。方法 :应用大鼠肾毒血清性肾炎模型 ,以尿蛋白定量 ,血清肌酐、尿素氮测定反映肾功能的改变。肾组织分别进行常规苏木素伊红(HE)、磷钨酸苏木素 (PTAH)、六胺银 -苏木素伊红复合染色 (PAM -HE) ,免疫荧光、光镜观察。结果 :静脉注射肾毒血清 (NTS)后 ,模型组大鼠肾功能有明显损伤 ,表现为血肌酐、尿素氮明显升高 ,尿蛋白阳性。 2周时 ,取肾组织活检 ,免疫荧光染色 ,可见IgG沿肾小球毛细血管壁呈连续线形沉积。 7周时 ,光镜观察可见肾小球系膜细胞增生 ,肾小球硬化和新月体形成 ,并有蛋白和红细胞管形。肾炎益气液组上述改变明显轻于模型组。结论 :肾炎益气液有不同程度的改善肾功能和减轻肾小球病变的作用。更多还原

【Abstract】 AIM: To investigate the therapeutic effects of "Shen Yan Yi Qi Solution",a chinese Medicine,on nephrotoxic serum nephritis in the rat. METHODS: Nephrotoxic serum nephritis model of the rat was set up by the Clarke’s method. RESULTS: Proteinuria and renal insufficiency occurred in all rats after nephrotoxic serum (NTS) injection,but symptoms in treatment group were reduced. At 2nd week,the typical linear deposition of IgG along the glomerular basement membrane (GBM) was observed by fluorescence microscopy. Mesangial hyperplasia and crescent formation in glomeruli were also observed by light microscopy. In treatment group,all the above lesions were alleviated. CONCLUSION: It demonstrated that "Shen Yan Yi Qi Solution" might alleviate the pathological change of glomeruli and improve renal function.更多还原
