title: [Isotopic equilibrium and thyroid secretion].
abstract: The long-term iodine turnover (140 days) of thyroid gland and plasma has been studied in rats in a steady state and receiving either 5 (group 5) or 50 (group 50) mug of iodine daily. At 60 days, the turnover of Thyroglobin is total (group 50) or 80% (group 5) but is total for PBI in the two groups. An iodine pool with a very slow turnover participates neither in the PBI secretion nor in the iodide recycling within the gland.
