An electronmicroscopic study was made on the thyroid gland of quail given the diet con tainning 0.1% thyouracil or not (a control), with special regard to the correlation between fine structures and function of the glandular cells.Follicular epithelial cells of the thyroid consisted of columnar, cuboidal and squamous cells, which were transformable from one to another according to their functional states. The low cuboidal and squamous cells were the main epitherial constituents in the nomal group, while the columnar cells were usually encountered in the group treated with thyouracil.The cokmnar cells in the group treated with thyouracil were characterized by the presence of abundant microvilli, rough endplasmic reticulum, large mitochondria and well-developed Golgi apparatus.These results suggested that the function of follicular epithelianl cells of the thyroid gland was activated in the quail by thyouracil administration.
