Intramuscular administration of estradiol dipropionate (OVOCYCLIN: CIBA, India) with a daily dosage of 1 mg per bird for 10 days, to male domestic ducklings, induced mitosis in the thyroid gland. Concomitantly, it decreased follicular epithelial height and increased colloidal material in the follicles. It is suggested that estradiol appears to have a dual action on the thyroid gland of the male duckling, since it accelerates mitosis but inhibits thyro-follicular activity of these birds.
对雄性雏鸭每日每只肌肉注射1毫克二丙酸雌二醇（OVOCYCLIN：CIBA，印度），持续10天，可诱导甲状腺细胞进行有丝分裂。同时，它降低了滤泡上皮高度，并增加了滤泡中的胶体物质。有人提出，雌二醇对雄性雏鸭的甲状腺似乎有双重作用，因为它加速有丝分裂，但抑制这些禽类的甲状腺滤泡活动。
