Figure 5

Alterations in antioxidant mechanisms. The antioxidant activity of the enzymes glutathione peroxidase (GPx) (a) and NADPH oxidase (NOX4) (b) was measured in the serum of rats exposed for 7, 14, and 21 days to As or PM2.5 or As + PM2.5. n = 4 per group. Data are presented as median (range). , PM2.5 (D14) vs PM2.5 (D28) to GPx and NOX4, respectively.
