2158745-9	1990	Under steady-state conditions in the presence of 25 mM HCO3(-)-5% CO2 at pHo 7.4, pHi was 7.40 +/- 0.02 and reversibly decreased to 7.23 +/- 0.01 on removal of Na+ (in the presence of amiloride) from the bathing medium, indicating that the Cl(-)-base exchanger is operative under basal conditions and functions as a base extruder.
