Abstract
- The production of CO2 in relation to sodium transport by toad urinary bladder has been examined in the absence of sodium from the serosal medium. 2. Replacement of serosal sodium by choline increased CO2 production without stimulating short-circuit current. Replacement of serosal medium by Tris did not have this effect. 3. With serosal sodium Ringer replaced by Tris Ringer, the ratio of sodium transported to CO2 produced was not altered significantly. 4. The results therefore suggest that there is no important recycling of sodium between the serosal medium and the transporting epithelial cells.
摘要
- 在浆膜介质中无钠的情况下，研究了蟾蜍膀胱产生二氧化碳与钠转运的关系。2. 用胆碱替代浆膜钠可增加二氧化碳的产生，而不刺激短路电流。用三羟甲基氨基甲烷替代浆膜介质则没有这种效果。3. 用三羟甲基氨基甲烷林格液替代浆膜钠林格液后，钠转运与二氧化碳产生的比率没有明显改变。4. 因此，结果表明在浆膜介质和转运上皮细胞之间不存在重要的钠再循环。
