Abstract
  1. Chloride concentration and osmolalities were compared in consecutively collected samples of proximal tubular fluid, peritubular capillary plasma and systemic plasma. 2. Mean chloride concentrations (m-mole/l) were 141.3+/-2.6 in tubular fluid, 114.8+/-1.7 in peritubular capillary plasma and 119.4+/-1.8 in systemic plasma. 3. Mean osmolalities (m-osmole/kg H2O) were 297+/-2.2 in tubular fluid, 293+/-2.4 in peritubular capillary plasma and 299+/-1.8 in systemic plasma. 4. These differences are discussed in relation to the anatomical and functional organization of the peritubular capillaries and renal tubules.
摘要
  1. 对连续采集的近端肾小管液、肾小管周围毛细血管血浆和全身血浆样本中的氯离子浓度和渗透压进行了比较。2. 肾小管液中氯离子的平均浓度(毫摩尔/升)为141.3±2.6,肾小管周围毛细血管血浆中为114.8±1.7,全身血浆中为119.4±1.8。3. 肾小管液中的平均渗透压(毫摩尔/千克水)为297±2.2,肾小管周围毛细血管血浆中为293±2.4,全身血浆中为299±1.8。4. 结合肾小管周围毛细血管和肾小管的解剖结构及功能组织对这些差异进行了讨论。
