Caloric Restriction Prevents Lead-Induced Oxidative Stress and Inflammation in Rat Liver

Figure 2

Liver superoxide dismutase (SOD) in ad libitum (AL) and caloric restriction (CR) groups after lead or saline administrations. Seven days of lead injections (15 mg/Kg body weight, ip) to AL animals caused significant reduction of liver SOD (* compared to the saline-injected AL); in CR animals SOD changes after the same dose lead administration were not significant. Liver SOD content was significantly higher in lead-administered CR compared to lead-administered AL (# compared to the lead-injected AL). The data are presented as means ± SEM.
