摘要
Purpose: Kidney stones (nephrolithiasis) are a widespread disease. Thus, blocking stone formation and finding new therapeutic methods is an important area of study. Diosmin (a major component of the bile) is known to have antioxidant as well as renoprotective effects. The present investigation aimed to evaluate the effect of diosmin on renal tissue protection in rats with ethylene glycol-induced nephrolithiasis. Materials and Methods: The rats were randomly divided into three groups. Group one (control) did not receive any treatments. In groups two and three, nephrolithiasis was induced by 2.5% (V/V) ethylene glycol + 2.5% (W/V) ammonium chloride (2 mL/d). The second and the third groups received distilled water or diosmin (80 mg/kg/d) by gavage for 21 days. Results: Stereological estimation of the renal structures revealed that the average volume of calcium oxalate (CaOx) in the nephrolithiasis+ diosmin rats was -63% less than in the rats with untreated nephrolithiasis (p< 0.01). The volume of the glomeruli, proximal and distal convoluted tubules, Henle's loop, collecting ducts, and vessels was reduced -32% to 58% after the induction of nephrolithiasis (p< 0.001). In the nephrolithiasis+ diosmin rats, on average, -70% to 96% of the glomeruli, proximal convoluted tubules, Henle's loop collecting ducts, and vessels remained intact (p< 0.01). Degeneration of the cortical tissue was 5-fold that of the medulla. In the nephrolithiasis+ diosmin rats, degeneration in the renal cortical tissue and medulla was reduced -70% and 44%, respectively, compared with that in the untreated nephrolithiasis group (p < 0.01). Conclusions: Diosmin reduces CaOx deposition and the degeneration of glomeruli and tubules in a rat model of nephrolithiasis.
