Abstract
The upsurge in copper oxide nanoparticle (CuONP) applications in various fields triggers hazardous effects on health. Resveratrol, a polyphenol found in plants of stilbene class, has been reported to decrease oxidative stress. The current study investigated the protective effect of resveratrol (RVT) against CuONP-induced hepatotoxicity and nephrotoxicity in male Wistar rats. CuONPs were prepared by precipitation method and characterized by X-ray diffraction (XRD) technique and scanning electron microscopy (SEM). Average crystallite size, lattice parameters (a, b, and c), volume of unit cell, and X-ray density were found to be 33 nm, (a = 4.691 Å, b = 3.409 Å, and c = 5.034 Å), 79.4 Å3, and 6.506 g/cm3, respectively, from XRD pattern. SEM showed uniform morphology of synthesized nanoparticles. Severe hepatic and renal injury was found in CuONP (300 mg/kg/day intragastrically (i.g.)) group after 7 days as shown by significantly increased serum levels of ALT, AST, creatinine, urea, and total oxidant status along with histopathological alterations. Resveratrol (60 mg/kg) treatment prevented the toxic effects induced by CuONPs. In conclusion, our data showed protective activity of resveratrol against toxic effects of copper oxide nanoparticles presumably through its antioxidant properties.
