STATUS OF PARATHYROID GLANDS FUNCTON BEFORE AND AFTER THYROID SURGERY ^{[№ 6 ' 2010]}
The author analyzes the results of surgery of 60 patients from 16 to 75 years old with different diseases of thyroid gland. It has been determined that frequency of reduction of calcium and parathormone level is decreased in the row — Graves’ disease, thyroid carcinoma, multinodular euthyroid goiter. Reduction of calcium and parathormone level relates to impairment of blood circulation and functional activity of parathyroid glands after thyroid surgery. After surgery the patients require prophylactic prescription of calcium drugs.
