镉和硒染毒对大鼠体内一些营养元素的影响

为了解染毒元素 Cd 和 Se 在生物体内对一些营养元素的影响，采用体内中子活化分析和原子吸收法分析了大鼠被高含量Cd或Se染毒后，不同组合的动物体内这些元素的平均含量的变化．结果表明，高含量 Cd 使大鼠体内N、Ca 、Zn 、Cu 的含量大幅度的降低，而高含量Se使大鼠体内 N、Ca、Zn 、Cu的含量有一定的降低；当高含量的 Cd和 Se 同时在大鼠体内作用时， Se 和 Cd 对 N、Ca 、Zn 、Cu 元素，的毒性作用有相互缓解作用，而Se 和 Cd 对 P、K、Mg 元素毒性却有相互加重作用．

The affection to some nutritional elements by Cd and Se poisoning in mice

In order to know the affection to some nutritional elements by Cd and Se poisoning in organism, the changes of the average content of some nutritional elements in mice were analysed with different poisoning groups using IVNAA and A.A.S.methods. The results show that poisoning from large content of Cd could be made N,Ca,Zn and Cu elements in mice seriously decreased; poisoning from large content of Se could be made these elements in mice decrease to a certain degree when large contents of Se and Cd exist in same organism,the action of Se could be relaxed the affection of Cd for decreasing of N,Ca,Zn and Cu;but for decreasing of P,K and Mg the action of Se and Cd would be added together.
