title: [Functional state of the pituitary-thyroid system of women during pregnancy].
abstract: Functional condition of the hypophysio-thyroid system was studied in physiological pregnancy by protein-bound iodine, T4, T3, thyrotropic hormone indices; the function proved to become more intense with the advance of pregnancy. A significant change of the T3 level during the early periods of pregnancy is possibly connected with the high hormone uptake at that period. A sharp elevation of the hormone-binding capacity of the blood serum proteins prevented the development of hyperthyroidism, this being confirmed by the results of the free thyroxin index determination.
