Cellular antioxidant status of BEAS-2B cells exposed to CuO/Silica and MCP230 ultrafine particles. Cells were co-treated with 100 μM deferoxamine (DF) or 25 μM resveratrol (RV) ± CuO/or MCP230 ultrafine particles for 4 h. (A) Depletion of intracellular glutathione (GSH) (B) Cytosolic superoxide dismutase (SOD) activity (C) Alterations in the glutathione peroxidase (GPx) enzyme activity. Results are expressed as mean ± SEM (n = 3). Significantly different from ^auntreated controls; ^bCuO/Silica; ^cMCP230.
