RESUMO
Cisplatin is one of the synthetic cancer medicines with nephrotoxicity being one of its major side effects. Past research shows that calcium dobesilate (CaD), as a vascular protective agent in diabetic retinopathy, has antioxidant properties. Thus, this study aims to evaluate the protective effects of CaD in cisplatin-induced nephrotoxicity in mice. A many as 28 mice, in the present experimental research, were randomly distributed into four groups, including control, cisplatin (the intraperitoneal administration of 20 mg/kg cisplatin only on the first day of the experiment), cisplatin + CaD 50 (cisplatin with the oral administration of 50 mg/kg CaD), and cisplatin + CaD 100 (cisplatin with the oral administration of 100 mg/kg CaD). The treated groups received CaD by oral gavage for 4 constitutive days. On the fifth day, the mice were sacrificed, and some biochemical (serum levels of Cr and BUN, renal tissue levels of MDA, and renal activities of SOD and GPx) and pathological parameters were evaluated. Based on the results, there was a significant decrease in the renal SOD and GPx activities; in contrast, there was a significant increase in the BUN, Cr, and renal MDA levels following administering cisplatin. However, the CaD treatment (100 mg/kg) significantly attenuated these alterations. In addition, the kidney's histological examination of kidneys confirmed the nephroprotective effects of CaD. The findings proved the protective impact of CaD on cisplatin-induced nephrotoxicity by an improvement in the oxidative stress factors.
