This study was designed to investigate the effects of dietary protein level on Pb, Fe, and Cu accumulation of the tissue of the Pb-administered rats. The dietary protein levels were 6% 15%, and 40% and the lead-exposed rats were given 2,000 ppm-Pb drinking water solution. After 3 weeks, half of the each group rats were sacrificed and the rest were sacrificed 4 weeks later. Hematocrit, hemoglobin, R8C content in blood were lower in Pb-administered groups than in Pb-free group. Protein levels of serum and liver in 6% casein Pb-administered group were lower than in control group. Pb contents of serum, liver, and kidney were significantly increased in 6% casein-Pb administered group. Fe contents of serum and kidney were increased in 40% casein Pb-administered group, whereas in liver, 6% casein Pb-administered group was higher than others.
