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

Figure 3

Blood catalase activity 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 CAT (* compared to the “before lead administration”); in Ex animals housed in the wheel equipped cages, CAT changes after the same dose lead administrations were not significant. The data are presented as means ± S.E.M. CAT: catalase; Sed Co: sedentary control group; Ex: exercise group.
