title: [Curative machanism of Shenle capsule on 5/6 nephrectomy rats].
abstract: OBJECTIVE
  To explore curative machanism of Shenle capsule on the 5/6 nephrectomy rats.
  
  
  METHODS
  Fibrin plate method was applied to examine activity of urinary plasminogen activator(PA). Semi-quantitative analysis was used to observe stained intensity and area of tissue-type plasminogen activator, urokinas-type plasminogen activator/ plasminogen activator inhibitor(tPA, uPA/PAI-1)in remnant renal tissue. Northern blot was employed to analyze the expression of transforming growth factor (TGF-beta) mRNA.
  
  
  RESULTS
  In model control group, the urinary PA activity and protein expression of tPA, uPA were down-regulated, but protein expression of PAI-1, TGF-beta mRNA was up-regulated in remnant renal tissue. In each treated group, the urinary PA activity and protein expression of tPA/uPA were enhanced,but the protein expression of PAI-1, TGF-beta mRNA decreased simultaneously.
  
  
  CONCLUSIONS
  Shenle capsule can delay glomerulosclersis and tubulointerstitial fibrotic lesions of remnant kidney by improving the activity of urinary PA and modulating the expression of tPA, uPA/PAI-1 and TGF-beta mRNA.
