title: [Effects of Haikun Shenxi on expression of platelet-derived growth factor-B and mRNA in renal tissue of rats with adriamycin nephropathy].
abstract: OBJECTIVE
  To investigate the effects of Haikun Shenxi on the expression of platelet-derived growth factor-BB (PDGF-BB) and mRNA in renal tissue of rats with adriamycin nephropathy.
  
  
  METHODS
  Rat model was established by unilateral nephrectomy and injecting adriamycin intraperitoneally. The adriamycin-induced nephrotic rats were randomly divided into 6 groups: normal group, sham operation group, model group, lotensin treatment group, Haikun Shenxi low and high dose treatment groups (0.77, 0.08 mg x kg(-1). Ten weeks later, the 24 hour urine protein and blood biochemistry examinations and renal pathologic changes were observed, and the expression of PDGF-BB and mRNA was measured using immunohistochemical method.
  
  
  RESULTS
  Compared with model group, proteinuria and the levels of serum creatinine (Scr) , urea nitrogen (BUN) were decreased obviously in both Haikun Shenxi low and high dose groups. The expression of PDGF-BB and mRNA was mostly presented in cytoplasm of renal tubular epithelial cells and mesangial area, and it could be reduced significantly after treatment (P < 0. 05).
  
  
  CONCLUSIONS
  The level of PDGF-BB and mRNA is high in renal tissue of adriamycin-induced nephrotic rats. This progress could be effectively inhibited by Haikun Shenxi and the mechanism may be that it can control the excessive expression of PDGF-BB and mRNA.
