Abstract

Silver nanoparticles are being used increasingly forbiomedical purposes because of their broad antimicrobialpotential. Their effects on cellular systems, however, havebeen addressed in only a few studies. We evaluated the ef-fects of these nanoparticles on the antioxidant status ofgroups of five male Wistar rats. Six groups of rats weregiven 100, 1000 or 5000 mg/kg daily through an oral can-nula for 7 or 14 days, one group received 5000 mg/kg for 21days, and a control group received distilled water. Theanimals were sacrificed 24 h after the end of treatment, andserum and tissue homogenates were prepared. Silvernanoparticles significantly (p<0.05) increased the con-centrations of malondialdehyde and superoxide dismutasebut decreased the levels of reduced glutathione, glutathioneS-transferase and catalase. These results indicate that silvernanoparticles may cause lipid peroxidation and alter anti-oxidant status in a manner that may cause oxidative stress.
