Abstract
  1. Male rats were given radiothyroxine and after 24 hr, approximately half the blood volume was replaced by exchange transfusion.2. Plasma concentration of radiothyroxine 2 hr after exchange averaged 81.1% of the value before exchange. This compared with a predicted mean of 97.1% assuming a free and rapid exchange of thyroxine throughout the thyroxine distribution space. The difference between the observed and expected value was highly significant.3. The effective exchangeable pool of thyroxine was found to be approximately twice the plasma volume.4. From these and other observations it is suggested that the liver and plasma constitute most of the exchangeable pool of thyroxine.5. This experiment supports a model of thyroxine metabolism which envisages essentially permanent binding of thyroxine by tissues other than the liver.
摘要

  1. 给雄性大鼠注射放射性甲状腺素，24小时后，通过换血置换约一半的血容量。

  2. 换血后2小时，放射性甲状腺素的血浆浓度平均为换血前值的81.1%。相比之下，假设甲状腺素在整个甲状腺素分布空间中自由快速交换，预测平均值为97.1%。观察值与预期值之间的差异非常显著。

  3. 发现甲状腺素的有效可交换池约为血浆体积的两倍。

  4. 从这些以及其他观察结果表明，肝脏和血浆构成了甲状腺素的大部分可交换池。

  5. 该实验支持一种甲状腺素代谢模型，该模型设想甲状腺素除肝脏外被其他组织基本永久性结合。
