Динамика гормонов щитовидной железы при выполнении модели стандартного перелома у кроликов

The participation of Se in the structure of deiodinases during the metabolism of thyroid hormones defined the interest to the research of its possible impact to the processes of reparative regeneration of bone tissue in the experiment. The aim of the paper is to reveal the dynamics of thyroid hormone secretion at further adding of selenium under the conditions of standard fracture healing in rabbits. The most general response of the thyroid gland at the reparative regeneration of bone tissue was revealed, it is the reduction of Т, T 4 and free T 4 concentration during the nearest postoperative period. It is shown, that the use of the preparation of Se changes the reaction of thyroid to the dosed damage of the bone and metabolism of iodothyronines as well. The change of T 3 concentration was the most evident. Rabbits having extra preparation of Se were less susceptible to fluctuations in the secretion of iodothyronines typical for the dosed damage of the bone but the syndrome of «low Т 3» redoubled and peripheral conversion of thyroid hormone reduced.
