Abstract:
Objective: To investigate the protective effect of compound Xueshuantong capsule against damage of diabetic nephropathy in rat diabetic model. Methods: Male SD rats were given intraperitoneal injection of streptozotocin (STZ) at 60 mg/kg, and diabetic rat model was deemed successfully induced when the blood glucose level ≥16.7 mmol/L 3 days after injection. Thirty model rats were randomly divided into the following 3 groups equally: diabetic model group (DM), compound Xueshuantong capsule group (XST), and α-lipoic acid treatment group (ALA). Another 10 normal rats served as normal control group (NG). The body weight, blood glucose, blood fat, kidney weight/body weight (KW/BW), 24 h-urinary protein excretion, urea nitrogen, and serum creatinine were observed and compared between different groups after 12 weeks' treatment. The ultrastructure changes of kidney were observed by electron microscopy and light microscope. Results: Compared with NG group, rats in DM group had a higher 24 h-urinary protein excretion (P<0.05), and those in XST group and ALA group had a significantly lower one compared with the DM group (P<0.05). Compared with NG group, rats in the other 3 groups had a higher KW/BW, with significant difference found between DM group and XST group (P<0.05). Electron microscopic results showed uneven glomerular basement membrane thickening, foot process integration, and mesangial cell proliferation in the model group; all the above changes were improved in the XST and ALA groups. Conclusion: Compound Xueshuantong capsule can lower the 24 h-urinary protein secretion, decrease KW/BW, and improve the structure of glomerular basement membrane, thus exerting renal protective effect in diabetic rats.
