【 摘 要 】
Evidence is provided that regulation of the Na+ -K+ pump activity in rat peritoneal mast cells occurs mainly through stimulation of the pump from inside the plasma membrane by sodium. It is demonstrated that there is a large reserve capacity for the exchange of intracellular sodium with extracellular potassium in these cells. The maximal pump activity was estimated to be 3230 cells per min and K m for extracellular potassium was 1.5 mM.
