Abstract
The effects of gossypol-acetic acid (a male contraceptive) on transmembrane fluxes of sodium and potassium in human red cells were studied, in comparison with the effects of ouabain (an inhibitor of Na+-K+-ATPase) and furosemide (an inhibitor of Na+, K+ cotransport). It was found that gossypol may be an inhibitor of outward (Na+, K+) cotransport in human red cells but has no significant effect on (Na+, K+)-ATPase. The results provide new evidence for elucidating the mechanism of hypokalemia caused by gossypol.
