title: [Restorative processes in the parathyroid glands in experimental hypothyroidism].
abstract: By means of morphological, morphometrical and autoradiographical methods restorative processes in the parathyroid glands in 41 euthyroid and in 41 hypothyroid rats have been studied during 1-24 days after mechanical trauma of the glands or after hemithyroparathyroidectomy. Seven hypothyroid and 7 euthyroid rats serve as a control. Hypothyroidism is produced with daily injection of mercazolil (6 mg/kg) 3 weeks before the operation and during the time of the experiment. In nonoperated hypothyroid rats development of hypertrophy in parathyrocytes is noted. Prolonged injection of mercazolil weakens (posttraumatic regeneration) or completely suppresses (compensatory hypertrophy) mitotic activity of the glandular cells (in comparison with the euthyroid animals). Manifestation of hypertrophy in parathyrocytes of the hypothyroid rats in comparison with the corresponding control is also less, than against the background of euthyreosis.
