ABSTRACT
<p><b>OBJECTIVE</b>To study the renal protective effect of sodium ferulate (SF) and its mechanism in rats with diabetic mellitus (DM).</p><p><b>METHODS</b>DM rats induced by streptozotocin were treated with SF 110 mg/kg per day for 8 weeks. The ratio of kidney weight/body weight (KW/BW), serum triglyceride (TG) and total cholesterol (TC), creatinine clearance rate (Ccr), urinary protein/24 hrs, levels of endothelin-1 (ET-1) and nitric oxide (NO) in renal cortex in rats were measured, the pathological change of kidney were observed and the expression of transforming growth factor-beta 1 (TGF-beta 1) and collagen IV (C-IV) in kidney were examined using immunohistochemical assay. The data obtained were compared with those obtained from untreated DM rats and normal rats respectively.</p><p><b>RESULTS</b>Compared with the normal rats, in DM rats, Ccr, urinary protein/24 hrs, ET-1, expressions of TGF-beta 1 and C-IV were significantly increased in DM model rats (all P < 0.01), and significantly abnormal pathological change in kidney was found. While in the SF treated DM rats, the above-mentioned abnormal changes were all significantly improved.</p><p><b>CONCLUSION</b>SF has effect in protecting kidney of DM rats, the mechanism might be related with its actions of reducing ET-1 production in kidney and inhibiting the expressions of TGF-beta 1 and C-IV.</p>
