The present study aimed to investigate the influence of grape seed extract (GSE) in renal toxicity, oxidative stress, and Bcl-2 expressions in Eltroxin-induced hyperthyroidism to male mice. GSE was evaluated through oral administration to male mice at dose 50 mg/kg daily for 3 consecutive weeks. Eltroxin (100 μg/kg) was administered to mice for 3 weeks, and the mice were posttreated with GSE for another 3 weeks. Results revealed that GSE administered to normal mice did not produce any signs of toxicity and did not cause any biochemical or histopathological changes. Posttreatment of Eltroxin-induced hyperthyroidism mice with GSE daily for 3 weeks improved all examined biochemical or histopathological features. Oral GSE can significantly normalize the elevated level of T3 and T4 in hyperthyroidism animals and elevated the reduced levels of TSH. Moreover, serum urea, creatinine, and electrolyte levels were significantly improved. GSE showed a potent antioxidant capacity in all oxidative stress markers assays (TBARS, reduced GSH, GST, SOD, and CAT) of kidney tissue homogenates. Furthermore, histopathological examination of kidney tissue of Eltroxin + GSE-treated group confirms the potential nephroprotective effect of GSE through increasing the anti-apoptotic marker Bcl-2.
