用含有30 mg/kg Cd(以CdCl_2形式)的饲料喂养小鼠8周,调查Cd对小鼠的毒性,向Cd饲料中补充Ca,P,Mg,Mn,Cu,Fe,Zn和Se以探讨这些金属元素对Cd的蓄积及毒性作用的影响。喂养8周后,鼠肝脏及肾皮质中Cd的浓度分别为13.9和19.5 mg/kg体重。试剂CdCl_2的纯度为99.9％以上,补充矿质元素的物质包括MgCl_2·6H_2O,CaHPO_4·2H_2O,KH_2PO_4,FeSO_4·7H_2O,CuSO_4·5H_2O,ZnCl_2,Na_2SeO_3·5H_2O及MnSO_4·H_2O
Mice were fed with a diet containing 30 mg / kg Cd (in the form of CdCl 2) for 8 weeks to investigate the toxicity of Cd to mice and to explore the effects of Ca, P, Mg, Mn, Cu, Fe, Zn and Se supplementation on Cd diet Effect of these metal elements on Cd accumulation and toxicity. After 8 weeks of feeding, Cd concentrations in rat liver and renal cortex were 13.9 and 19.5 mg / kg body weight, respectively. The purity of the reagent CdCl 2 is above 99.9%. The mineral elements are MgCl 2 · 6H 2 O, CaHPO 4 · 2H 2 O, KH 2 PO 4, FeSO 4 · 7H 2 O, CuSO 4 · 5H 2 O, ZnCl 2, Na 2 SeO 3 · 5H 2 O and MnSO 4 · H 2 O
