This study was performed to investigate the effects of peking-duck extracts added with medicinal herbs(DJ) on the intoxication of heavy metals (Hg, Pb, Cd, As) in rats. Sprague-Dawley rats weighing 150$\pm$15g, were randomly assigned to groups: basal diet only in normal control group(NCG): basal diet and heavy metals without DJ injection in heavy metal control group(HMC); basal diet, heavy metals and DJ(3mg/ml) injection in heavy metal low duck-juice group(HMLD), basal diet, heavy metals and DJ(30mg/ml) injection in heavy metal middle duck-juice group(HMMD): basal diet, heavy metal and DJ(300mg/ml) injection in heavy metal high duck-juice group(HMHD). Hg and As was injected by 50ppm and Cd and Pb by 25ppm for 17days. Also DJ oral feeding was conducted for 28days. The result of this study were as follows: Food intake and body weight gain in heavy metal administered groups were lower than those of NCG. Liver, kidney and testis weights were not significantly different among 5 groups. GOT, GPT and BUN activities were significantly reduced in DJ treated groups as compared to HMC. DJ showed the suppressing effect on the accumulation of Hg, Pb and Cd in serum, liver and kidney. Fecal Hg and Cd excretions increased with DJ feeding. The results suggested that DJ may have some protective effects on Hg, Cd and Pb intoxication by reducing the accumulation in tissues and increasing excretion. This study also showed the effective way of using duck-extract and its application to the oriental medicine.
