Abstract
In connection with a compartment theory, a kinetic study of thyroid metabolism in man requires the determination of the specific iodine activity at all accessible levels (plasma, urines, faeces), during periods of over a month; The basic methods required for such a study are therefore the use of iodine-125 as a tracer, the exact determination of iodine-127 using activation analysis and the setting-up of a daily diet of constant iodine content. The results are presented for each particular case and the main parameters of thyroid metabolism are calculated. The discussion includes some special considerations concerning the pathological condition of the subject or a break in the thyroid equilibrium. It shows in particular that constant disagreement exists between the experimental curves for the specific iodine activity and the corresponding theoretical curves for a conventional thyroid process based on 3 compartments; these discrepancies concern both the inorganic iodine and the organic iodine eliminated with the faeces.
