Proximal tubules of the kidney have been injected in vivo with isotonic solutions (in mequiv./1: 120 NaCl; 120.4 Na, 114.0 Cl, 6.4 HCO3 and 120 Na, 60 Cl, 60 HCO3) and half time (t 1/2) of fluid absorption was measured by shrinking drops technique. The value of t 1/2 was found to be significantly lower for NaCl solution than for NaCl--NaHCO3 (1:1) one. These data suggest that proximal reabsorption of chloride and bicarbonate is provided by separate specific transport systems.
用等渗溶液（毫当量/升：120氯化钠；120.4钠、114.0氯、6.4碳酸氢根和120钠、60氯、60碳酸氢根）对肾近端小管进行体内注射，并通过液滴收缩技术测量液体吸收的半衰期（t1/2）。发现氯化钠溶液的t1/2值明显低于氯化钠 - 碳酸氢钠（1:1）溶液。这些数据表明，氯和碳酸氢根的近端重吸收是由不同的特定转运系统完成的。
