This study was undertaken to investigate the effects of dietary low (Fe) levels on Fe metabolism of cadmium(Cd) poisoned rats. 40 male Sprague weaning Dawley rats weighing 80-90g were divided into 4 groups(LFe:low Fe, LFeCd:low Fe and Cd, AFe: adequate Fe, AFeCd: adequate Fe and Cd) according to Cd administration(0, 50ppm in drinking water) and Fe levels(Fe:6ppm, 40ppm in diet)for 12 weeks. The food intake and body weight gain of Cd group with low Fe(LFeCd) were significantly lower than those of without Cd group with adequate Fe(AFe)(p<0.01, P<0.05). But there was no significantly difference between Cd groups and without Cd groups in water intake. The blood levels of hemoglobin, hematocrit, and serum levels of Fe of LFeCd were significantly lower than those of AFe(p<0.01, p<0.05, p<0.001). The urinary and fecal excretion of Fe of LFeCd was significantly lower than that of AFe(p<0.05, p0.05). The levels of Fe of liver, spleen in LFeCd were lower than those of AFeCd(p<0.05, p<0.05). These results indicates that adequate iron supplementation to Cd pretreated rats induce protective effects on the reduction of Fe status by Cd poisoning.
