title: [In vitro thyroid hormone reception by the adenohypophysis and hypothalamus of male rats of different ages].
abstract: In studying the thyroid hormone binding with the water-salt extracts of the adenohypophysis and the hypothalamus of male rats after Schreiber it was shown that with ageing there occurred in the adenohypophysis a redistribution of T4 and T3 binding in the direction fo an increase of the T4/T3 coefficient, and a reduction of the relative T3 binding, the latter bordering with the significant one. Some reduction of the T4/T3 coefficient, both in comparison with the rest of the tissues under study and in age aspect, was peculiar to the posterior hypothalamus. In the rats-tumour-carriers some changes in the thyroid hormone binding (reduction of the T4/T3 index in the posterior hypothalamus and its sufficiently high values in the adenohypophysis and the anterior hypothalamus) were similar to those observed in normal and ageing rats.
