The aim of the present investigation was to explore the mitogenic action of ovine and bovine prolactin hormones in the thyroid, the parathyroid and the thymus glands of chicks. Both the hormones in lowest dosage (1.5 i.u.) increased the mitotic rate in majority of these organs, but it failed to accelerate the mitotic incidence further or were almost ineffective with the higher dosages (5 i.u. and 10 i.u.). Ovine prolactin showed a higher mitogenic response than that seen with the bovine hormone. It is suggested that prolactin in optimal dosage promotes mitosis in these organs of chicks.
本研究的目的是探讨绵羊和牛催乳素激素对雏鸡甲状腺、甲状旁腺和胸腺的促有丝分裂作用。两种激素的最低剂量（1.5国际单位）均能提高这些器官中大多数的有丝分裂率，但更高剂量（5国际单位和10国际单位）未能进一步加速有丝分裂发生率，或几乎无效。绵羊催乳素的促有丝分裂反应高于牛催乳素。提示最佳剂量的催乳素可促进雏鸡这些器官的有丝分裂。
