The Radioprotective Effect of Methylthiouracil on the Thyroid Gland of the Rat

Abstract
Irradiation of the rat thyroid gland in vivo inhibits the capacity of the gland to undergo hyperplasia under the stimulus of a goitrogen. An intraperitoneal injection of an aqueous solution of 50 mg methylthiouracil before irradiation significantly reduced the degree of this inhibition.
