Biliary excretion of cadmium was studied in two groups of five rats which were given repeated injections of 109Cd. The first group was given a total amount of 6 mg Cd/kg which was 6 times as much as the second group. The elimination of cadmium in bile, urine, and feces was measured 4 to 5 weeks after the last injection. The relative biliary excretion of cadmium was the same in both groupetion, which was 0.001% but, less than the total fecal elimination of cadmium, which averaged 0.034% during the same time.
对两组各五只大鼠进行了研究,这些大鼠反复注射了¹⁰⁹Cd,以研究镉的胆汁排泄情况。第一组给予的镉总量为6毫克/千克,是第二组的6倍。在最后一次注射后4至5周测量胆汁、尿液和粪便中镉的消除情况。两组中镉的相对胆汁排泄量相同,均为0.001%,但低于镉的粪便总消除量,在此期间粪便中镉的总消除量平均为0.034%。
