Abstract
The biochemical structure and the immunological properties of the long-acting thyroid stimulator (LATS) and thyrotropin (TSH) are different (1), but their effects on the thyroidal iodine metabolism are similar, differing only in their time course (2, 3). Histologic studies have so far failed to show any major qualitative difference between the TSH and LATS stimulated thyroid glands. Both substances appear to affect in a similar manner the height of the thyroid follicular cells, the staining properties of the colloid (4) and the formation of intracellular colloid droplets (5). The similarities described above may suggest that TSH and LATS act on the thyroid gland through the same mechanism (6). In order to elucidate this problem, we have compared the ultrastructural changes induced by LATS and TSH in the thyroid of mice having their endogenous TSH secretion suppressed by the administration of thyroxine.
