The effect of acute cold (10 degrees) exposure on the tissue level of triiodothyronine (T3) and on the conversion of thyroxine (T4) to triiodothyronine, both in vitro and in vivo, has been investigated in young chickens previously thyroidectomized or hypophysectomized. It was found that cold exposure stimulates T4 to T3 conversion both in vivo and in vitro not only in intact animals but also in hypophysectomized and thyroidectomized ones. It is concluded that peripheral metabolism of thyroid hormones represents a self-standing but not sole route of adaptation to changes in environmental temperature.
在先前已进行甲状腺切除或垂体切除的幼鸡中，研究了急性冷暴露（10摄氏度）对三碘甲状腺原氨酸（T3）组织水平以及甲状腺素（T4）向三碘甲状腺原氨酸转化的影响，包括体内和体外的影响。结果发现，冷暴露不仅在完整动物中，而且在垂体切除和甲状腺切除的动物中，均能在体内和体外刺激T4向T3的转化。得出的结论是，甲状腺激素的外周代谢是适应环境温度变化的一个独立但非唯一途径。
