Shariatpanahi 2015 09 28 The teratogenicity of cadmium exposure was studied in virgin NIMRI rats aged 10-13 weeks. Pregnant animals were fed cadmium sulfate equivalent to doses of 1,4 and 7 mg/kg/day of cadmium by oral gavage on the day 7 of gestation. On the day 18 of gestation, fetuses were delivered and examined for external and skeletal malformations. Total percent of malformed fetuses in rats treated by different doses of cadmium were significantly higher than of control group. In this study the length of arm, big diameter of chest, big diameter of pelvis, length of femur, length of tibia, length between crown to sacrum, large diameter of skull and length between crown to bottom were examined. The appearance of total skeletal malformation in treated groups started by dose of 1 mg/kg/day of cadmium (p https://acta.tums.ac.ir/index.php/acta/article/view/1755 https://acta.tums.ac.ir/index.php/acta/article/download/1755/1748
