Study Title:

Grape Seed Extract Alleviates Dexamethasone-Induced Hyperlipidemia, Lipid Peroxidation, and Hematological Alteration in Rats.

Study Abstract

The ameliorative effects of dietary natural compounds have drawn increasing attention. Dietary antioxidant is considered a common practice adopted in traditional and alternative medicine. The current study was considered to assess the ameliorative effect of grape seed extract on dexamethasone-induced hepatotoxicity in rats. Rats were injected with dexamethasone, (0.1 mg/kg; i.m.), three times per week, for 30 days. The other groups; dexamethasone (0.1 mg/kg) and grape seed extract at a dose of 200 and 400 mg/kg were given orally to rats, respectively. Dexamethasone treatment resulted in a significant elevation in liver function markers activities, lipid profile, and hematological alterations; also, a remarkable increase in hepatic lipid peroxidation marker whereas decreased antioxidant activities in rats. However, administration of grape seed extract resulted in a reversal of dexamethasone-induced lipid peroxidation, antioxidant enzyme activities, liver function markers and lipid profile, and hematological alterations. Moreover, grape seed extract demonstrated preventive action against dexamethasone-induced histopathological changes in rat liver tissues. In conclusion, grape seed extract exhibited a protective effect in rats against oxidative stress, hyperlipidemia and hematological alterations induced by dexamethasone.
