1. 在各种介质中，测量了完整的和去垂体的堪萨斯眼底中氚化水的交换速率。2. 垂体切除术降低了淡水中的交换速率。3. 低剂量（30亩）的绵羊催乳素刺激淡水中垂体化鱼类的水分周转。4. 随着盐度的增加，完整动物和去垂体动物的交换率均下降。5. 合成溶液的实验表明，海水和高盐度环境中交换速率的下降主要是由于钙离子的影响。6. 养在含低钙浓度的合成海水中的鱼，与养在正常海水中的鱼相比，具有更高的氚化水交换率和更高的饮水率。
1. Measurements have been made of the rate of exchange of tritiated water in both intact and hypophysectomized Fundulus kansae in a variety of media. 2. Hypophysectomy reduces the rate of exchange in fresh water. 3. Low doses (30 mu) of ovine prolactin stimulate water turnover in hypophysectomized fish in fresh water. 4. The rate of exchange declines in both intact and hypophysectomized animals with increasing salinity. 5. Experiments with synthetic solutions show that the decline in the rate of exchange in sea water and in higher salinities is due mainly to the effects of calcium ions. 6. Fishes maintained in synthetic sea water containing a low concentration of calcium have both a higher rate of exchange of tritiated water and a higher drinking rate than fish in normal sea water.
