Copper oxide nanoparticles induces oxidative stress and liver toxicity in rats following oral exposure

摘要

The present study aimed to evaluate the effect of Copper Oxide (CuO) Nanoparticles (NP) on liver following oral exposure in rats. A total of 18 male wister rats were used in the experiments including a control group (6 rats). NP were given to the rats with a doses (5, 50?mg/kg b.w./day) via oral gavage and a control group (received only 200?μl PBS). The treatment was continued for 14 days. The supernatants of rat Liver tissue homogenates were used to analyze for glutathione levels (GSH), Catalase, superoxide dismutase (SOD), the extent of lipid peroxidation products (Malondialdehyde, MDA). Oral administration of NP to rats caused a significant (P?
