ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effects of Shenkangwan on the expressions of angiotensin II (AngII) and its type I receptor (AT(1)R) and the renalprotection mechanism of Shenkangwan in rats with early diabetic nephropathy (DN).</p><p><b>METHODS</b>The rat models of DN established by a single injection of streptozotocin were randomly divided into 4 groups, namely the model group, Shenkangwan treatment group, irbesartan treatment group, and Shenkangwan and irbesartan treatment group, with normal rats as the control. All the rats received daily gavage for 8 weeks. The urinary protein quality in 24 h and plasma and renal contents of AngII were measured. The expressions of AT1R at the protein and mRNA levels in the kidney tissues were measured by immunohistochemistry and reverse transcription-polymerase chain reaction, respectively. The pathological changes of the kidney were observed microscopically.</p><p><b>RESULTS</b>In DN rats, Shenkangwan reduced the urinary protein quantity in 24 h and the contents of AngII in the plasma and kidney tissues, decreased the renal expressions of AT(1)R protein and mRNA, and alleviated the morphological damage of the kidney.</p><p><b>CONCLUSIONS</b>Shenkangwan offers renalprotection against DN probably by reducing the contents of AngII in the plasma and kidney tissues and inhibiting renal AT(1)R expressions.</p>
