Quantitative Aspects of Iodine Metabolism. The Exchangeable Organic Iodine Pool, and the Rates of Thyroidal Secretion, Peripheral Degradation and Fecal Excretion of Endogenously Synthesized Organically Bound Iodine

H-Hyperthyroid. E-Euthyroid.t Fecal excretions were not obtained in these subjects.The plasma iodide concentrations were estimated by assum- ing that fecal excretion of organic iodine was 12} per cent of the value obtained for organic iodine degradation.-
