[In vivo regulation by calcium of thyroid metabolism of iodine in rats].
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.
