Abstract

In the normal thyroid, but not necessarily in the goitrous gland, the bulk of iodine is bound to thyroglobulin. Even in the normal thyroid-and much more so in goiters-iodine is contained in many different compartments with widely differing kinetics, biochemical composition, localization, and physiologic significance. Any change of thyroid function profoundly affects intrathyroidal iodine kinetics and produces a redistribution of stored iodine. This must be taken into account whenever the impact of a global change in intrathyroidal iodine stores on thyroid function and growth is studied in vivo.
