[Development of thyroid peroxidase activity during the early stage of iodine deficiency in the hypophysectomized rat].

Abstract

The iodide-peroxidase activity of the thyroid gland remains, in hypophysectomized Rats maintained on a low iodine diet, below normal value. This result suggests that the early increase of peroxidase activity observed in control Rats maintained on a low iodine diet is TSH dependent.
