ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effects and mechanisms of Yishen Huoxue decoction (YHD) on chronic renal failure (CRF) rats induced by 5/6 nephrectomy.</p><p><b>METHODS</b>The glomerulosclerosis model was established by 5/6 nephrectomy in rats. Experimental animals were allocated into the normal group, the model group, the YHD group and the benazepril group. Urine protein of 24 h (UP) at the 6th and 12th weekend after operation, blood urea nitrogen (BUN) and creatinine (SCr), albumin (Alb) and haemoglobin (HB) at the 12th weekend were measured, renal pathology changes were examined with light microscope, the expressions of proliferating cell nuclear antigen (PCNA) and fibronectin (Fn) were examined by immunohistochemistry and mRNA expressions of connective tissue growth factor (CTGF) and plasminogen activator inhibitor-1 (PAI-1) by RT-PCR at the 12th weekend.</p><p><b>RESULTS</b>Compared with those in the normal group, the levels of UP, BUN and SCr, the area of glomerular mesangial matrix, the FN deposition, PCNA expression in glomeruli and tubular interstitium and mRNA expressions of CTGF and PAI-1 were all significantly higher in the model group (P < 0.05). All the above-mentioned indexes were lower in the YHD group than those in the model group (P < 0.05). PCNA positively expressed cells in glomeruli of the normal, model group, YHD group and benazepril group was 7.00 +/- 2.24,34.78 +/- 6.96,15.75 +/- 2.61 and 15.50 +/- 2.57 respectively, positively correlated to the expression of CTGF, PAI-1, FN and SCr level.</p><p><b>CONCLUSION</b>YHD could delay the progression of CRF in 5/6 nephrectomized rats, and the mechanisms were mainly related to the inhibition on renal cell proliferation and it induced over-expression of cytokines, and accumulation of extracellular matrix.</p>
