Abstract

In vivo experiments using a calcium deficient or a normal diet, proved that calcium enhance iodine entry and concentration into the thyroid gland of the rat and the intra-thyroidal T4 pool, T4 level in serum was also increased. Peripheral metabolism of T4, serum TSH levels and pituitary TSH contents were unaffected. Calcium has a local regulatory function on the thyroid gland.

摘要

使用缺钙或正常饮食的体内实验证明，钙可促进碘进入大鼠甲状腺并提高其在甲状腺内的浓度，甲状腺内的T4储备增加，血清T4水平也升高。T4的外周代谢、血清促甲状腺激素（TSH）水平和垂体TSH含量均未受影响。钙对甲状腺具有局部调节作用。
