CONDITION OF THE ERYTHROID PART OF BLOOD SYSTEM AT STRESSED ANIMALS WITH HYPOTHYREOSIS

Abstract

Hypothyreosis, caused by introduction of mercazolil, leads to reduction of production of thyroid hormones, destabilization of membranes and. acceleration of erythrocytes destruction, activation of erythropoiesis, development of macroerythrocytosis in blood. In 28 days after cancelling of mercazolil reserves of red bone marrow are exhausted, in blood microerythrocytosis accrues. The stress in animals with hypothyreosis does not change the composition of blood erythrocytes and activity of erythrocytopoiesis, but promotes preservation of a marrowy reserve of erythrocytes and increases a level of thyroid hormones.
