Lowering of the acclimation temperature of the eel induced a reduction of 32P incorporation into the lipid phosphorus of various tissues. This effect was partly the result of a slight decrease of the inorganic phosphate exchange and metabolism of tissues. 2. The variation of the 32P incorporation into the various phosphatides was different according to the tissue ; gill and kidney phospholipids being the most effected. At high temperature (22 degrees C), the turnover of sphingomyelin and phosphatidyl-choline was four or seven fold higher in all tissues than at low temperature. At low temperature (12 degrees C), the incorporation of 32P into gill and kidney phosphatidylinositol and gill diphosphatidyl-glycerol was the same as at high temperature. The kidney diphosphatidyl-glycerol turnover was affected to the same extent as the other phosphatides by high acclimation temperature. The gill phosphatidyl-ethanolamines had a relatively higher turnover at low temperature. 3. The acclimation of the eel at low temperature provoked an increase of the turnover of phosphatidyl-ethanolamine and diphosphatyl-glycerol into the gill, parallel with an increase of some enzymatic activities. 4. The variation of the acclimation temperature may impose restrictions on the turnover of some phosphatides. There is a limited action of the temperature on the turnover of metabolically active phosphatides of the osmoregulatory organs, such as gill phosphatidyl-inositol and diphosphatidyl-glycerol or kidney phosphatidyl-inositol. 5. The significance of these findings is discussed in relation to the role of phospholipids in the cell and to the physiological functions of the various organs of the eel.
降低鳗鱼的驯化温度会导致其体内32P掺入各种组织脂质磷的量减少。这种效应部分是由于组织中无机磷酸盐交换和代谢略有下降所致。2. 32P掺入各种磷脂的变化因组织而异；鳃和肾磷脂受影响最大。在高温（22摄氏度）下，所有组织中鞘磷脂和磷脂酰胆碱的周转率比低温时高4倍或7倍。在低温（12摄氏度）下，32P掺入鳃和肾磷脂酰肌醇以及鳃二磷脂酰甘油的量与高温时相同。肾二磷脂酰甘油的周转率受高驯化温度的影响程度与其他磷脂相同。鳃磷脂酰乙醇胺在低温下的周转率相对较高。3. 鳗鱼在低温下驯化会导致鳃中磷脂酰乙醇胺和二磷脂酰甘油的周转率增加，同时一些酶活性也增加。4. 驯化温度的变化可能会对某些磷脂的周转率施加限制。温度对渗透调节器官中代谢活跃的磷脂周转率的作用有限，如鳃磷脂酰肌醇和二磷脂酰甘油或肾磷脂酰肌醇。5. 结合磷脂在细胞中的作用以及鳗鱼各器官的生理功能，对这些发现的意义进行了讨论。
