RESUMO
<p><b>AIM</b>To study the effect of angiotensin-(1-7) on the kidney of diabetic rats by observing the mRNA expression of PDGF and TGF-beta1.</p><p><b>METHODS</b>SD rats were divided into three groups: Group C (uni-nephrectomy control group), Group D (diabetic model control group), Group T (Ang-(1-7) treated group). We evaluated blood glucose,urea nitrogen, creatinine and urine albumin excretion respectively, studied the renal morphology by light microscope, and detected the gene expression of PDGF, TGF-beta1 in renal tissue by RT-PCR technique.</p><p><b>RESULTS</b>There was significant difference between the group D and T about the RW/BW, renal morphology, the total urine protein and the mRNA expression of PDGF and TGF-beta1.</p><p><b>CONCLUSION</b>Ang-(1-7) can relieve the renal process of diabetic rats.</p>
