The Effect of Rutin on Cisplatin-Induced Oxidative Vestibular Nerve Damage in Rats

Oxidative stress is considered responsible for cisplatin autotoxicity. The aim of this study was to examine the protective effect of rutin on cisplatin-induced oxidative vestibular nerve damage in rats. Animals were divided into four groups (n = 6): healthy group (HG), 50 mg/kg rutin + cisplatin group (RG-50), 100 mg/kg rutin + cisplatin group (RG-100), and cisplatin group (CG). Rutin was administered orally for eight days, and 5 mg/kg cisplatin was injected intraperitoneally once every two days. Malondialdehyde, myeloperoxidase, and total glutathione levels were measured in serum and vestibular nerve tissue and examined histopathologically. Malondialdehyde and myeloperoxidase levels were lower in the serum and vestibular nerve tissue of RG-50 and RG-100 groups compared to the CG group; total glutathione was higher. Also, several histopathological changes were seen in the vestibular nerve tissue of the CG group. Rutin inhibited nerve tissue damage and may protect vestibular nerve tissue from cisplatin-induced oxidative damage.
