the results are discussed in terms of a model which explains cellular swelling in acetate media in terms of ( a ) non-ionic diffusion of acetic acid across plasma membranes impermeable to the acetate anion , ( b ) removal from the cells of the hydrogen ion gained with the acetate by amiloride-sensitive sodium-hydrogen counter-transport and ( c ) subsequent extrusion of sodium from the cell accompanied by potassium uptake via the ouabain-sensitive na+-k+-atpase .
