Voluntary Exercise Prevents Lead-Induced Elevation of Oxidative Stress and Inflammation Markers in Male Rat Blood

Figure 2

Blood glutathione peroxidase in sedentary control and exercise groups before and after lead administrations. Seven days of lead injections (15 mg/Kg body weight, ip) to sedentary animals housed in the regular cages caused significant reduction of blood GPx (* compared to the “before lead administration”); in Ex animals housed in the wheel equipped cages, GPx changes after the same dose lead administrations were not significant. The data are presented as means ± S.E.M. GPx: glutathione peroxidase; Sed Co: sedentary control group; Ex: exercise group.
