Some dynamic aspects of the thyroid function studied by a method of isotopic balance; Quelques aspects dynamiques de la fonction thyroidienne etudies par une methode d''equilibre isotopique'

Abstract

This report addresses the use of a method which aims at directly measuring quantities of steady iodine involved by the thyroid metabolism in specific physiological conditions. The experiment is based on the use of male rats weighting 180 to 200 g which received an almost iodine-free diet. The daily dose of iodine is administered to each experimental group through beverage under the form of potassium iodide. After a delay, the usual beverage is replaced by a marked one. Iodine renewal by thyroid is monitored in vivo by external detection of radiations emitted by iodine 131. At the end of the experiment, rats are killed, and their blood is collected on heparin, centrifuged and processed to separate mineral iodine and hormonal iodine. Radioactivity is then measured with a scintillator and compared with that of a beverage sample [French] Le but de la methode utilisee est de mesurer directement les quantites d'iode stable mises en jeu par le metabolisme thyroidien dans des conditions physiologiques precises.
