ABSTRACT The offspring of bitches treated with thiouracil during pregnancy and lactation were studied with regard to certain aspects of iodine metabolism and also to the morphological effect on the thyroid gland, as compared with controls of the same age and weight. At the age of six months, when the dogs were virtually fully grown, the thyroid gland still exhibited the effects of the thiouracil treatment of the mothers as manifested by an increased uptake of 131I, enlargement, and histological changes of a hyperplastic type. The significance of these deviations from normal iodine metabolism and morphology is discussed with particular reference to the dangers of thiouracil medication during pregnancy.

1. In a series of rabbits the changes which took place in the histology of the left lobe of the thyroid gland after excision of the right lobe have been studied at varied intervals of time. 2 days after the removal of one lobe the other lobe showed a slightly increased colloid content, an increased vacuolation of the colloid, and a slight increase in the size of the epithelial cells. At the end of a week the vesicles were greatly increased in size, distended with colloid, and the epithelial cells were flattened, while after 3 to 4 months signs of compensatory hypertrophy were present. 2. The changes observed were uninfluenced by division of the vagus or cervical sympathetic.

1. There is a marked individual variation in the histological structure of the thyroid gland of rabbits examined at the same season under standard conditions. Although the microscopic appearance varies in different rabbits, the structure of the two lobes in the same animal does not differ. The variations are seen principally in the size and shape of the vesicles and in the quantity and character of the colloid. 2. With one lobe as a control no histological changes in the other lobe have been observed following section or stimulation of either the cervical sympathetic or the vagus and its branches.
