To study the effect of Qingshen capsule on the renal function of the 5/6 nephrectomized rats and its protective effect on the structure of the remnant kidney.After treated for 12 weeks,the rats were sacrificed.The serum ceratinine(Scr) was measured and the renal lesions and the collagen deposition in the sclerosis glomerulus were investigated.Results:The Scr of Qingshen capsule groups is lower than that of the other two groups.Qingshen capsule and Cap can inhibit the glomerular hypertrophy,decreased ECM and abate collagen deposition in the glomerulus.Conclusion:Qingshen capsule not only can delay the progress of chronic renal failure,but also play a protective role on renal remnant kidney.
