| Abstract |
|
In order to investigate the effect of sulfamonomethoxine on the thyroid gland, healthy mongrel dogs were selected at random. The body weights of these animals ranged between 1850 and 2050g at the beginning of the experiment. The 12 dogs used in this work were allotted to groups of two. Dogs in one group served as controls and the others were administered sulfamonomethoxine of 50 mg/kg/day for 15 weeks. The results obtained in this work were summerized as follows: 1. Mean body weights of experimental dogs revelled a slow increasing tendency but weights of thyroid glands were increased highly. 2. Thyroid follicles were atrophied significantly in accordance with experimental term and their colloidal substance was not found on stained sections. 3. It indicated the appearance of typical hyperplastic goiter. New follicular epithelial cells which were changed into hypertrophic cuboidal and columnar in type showed degeneration and necrosis and those cells multiplied difusely and made new small follicles. |
