[The character of functional connections in the endocrine system of female white rats and their transformation with age].
The authors studied the functional interrelations between the adrenal glands and the thyroid gland of female albino rats of various age groups. Blood content of 11-oxycorticosteroids and protein-bound iodine was determined. Analogous determinations were carried out in partial exclusion of the adrenal gland function (metapyron block) and of the thyroid gland function (6-methyluracil block). It is supposed that in the young sexually-mature female albino rats the functions of the adrenal glands and the thyroid gland were in direct relationship irrespective of the cyclic variations in the sex steroid secretion; with the advance of age this association became deranged.
