Abstract: | Under study were the morphofunctional features of adrenal glands of 1, 10, 20, 30 and 40-day-old rats born by females with experimental hypothyrosis obtained by bilateral subtotal parathyroidectomy and blocade of the gland functioning by mercazolil (3 mkg/kg). The experimental treatment preceded pregnancy. The antithyroid drug was injected during pregnancy and lactation. The posterity of experimental animals was established to have a decreased need in oxygen as compared with controls. Their adrenal glands were of less weight (especially in off-springs of parathryodidectomized rats in the neonatal period). There are a number of morphometrical and histochemical signs suggesting the suppression of the functioning of the cortical and medullary substance, including the period of adaptation of the organism to the extrauterine life. |
