Effect of Glycine on Lead Mobilization, Lead-Induced Oxidative Stress, and Hepatic Toxicity in Rats

Table 1

Lead concentration in the blood (μg/dL), brain, liver, kidney, and bone (μg/g) of rats. Lead was given in drinking water for 5 weeks, after which, the lead was withdrawn and the rats (1) received plain water for 5 days or (2) received plain water for 28 days.
