Abstract
  1. An attempt has been made to locate the site of action of vitamin D(3) as it affects the translocation of calcium across the intestine. 2. Calcium appears to be pumped out of cells by a process dependent on energy from metabolism. 3. The effects of cold, inhibitors and vitamin D(3) on the translocation of calcium by everted sacs of intestine were studied and compared with results obtained in vivo. 4. A model was proposed to explain the results which suggests that vitamin D(3) inhibits a metabolically operated pump that returns calcium from the mucosal cell to the lumen. 5. Some observations on the effect of sodium lauryl sulphate on the translocation of calcium in vivo and in vitro are reported.
摘要
  1. 人们已尝试确定维生素D(3)影响钙在肠道转运的作用位点。2. 钙似乎通过一个依赖代谢能量的过程被泵出细胞。3. 研究了低温、抑制剂和维生素D(3)对肠外翻囊泡钙转运的影响,并与体内实验结果进行了比较。4. 提出了一个模型来解释这些结果,该模型表明维生素D(3)抑制了一个将钙从黏膜细胞运回肠腔的代谢驱动泵。5. 报告了关于十二烷基硫酸钠对体内和体外钙转运影响的一些观察结果。
