[Bimodal secretion of thyroid hormones].
In rats receiving 50 mug of iodine daily, the turnover curve of plasmatic hormones is bimodal. Simultaneously, a flux of direct secretion and a flux of delayed secretion participate in the hormonal secretion. The second flux is about twenty times greater than the first one. The delay of its turnover is probably due to the diffusion of the molecules of thyroglobulin into the colloid.
