We studied the regulation of cell volume and cation content in erythrocytes stored at 4 degrees C under blood bank conditions for various lengths of time and subsequently incubated in autologous plasma at 37 degrees C for 4 or 24 h. Cell swelled during storage at 4 degrees C whereas marked K+ loss and cell shrinkage were observed when erythrocytes were incubated at 37 degrees C in autologous plasma. The cell shrinkage was inhibited only by the K+ Cl- cotransport-specific inhibitor, [(dihydroindenyl)oxy] alkanoic acid, and not by other specific inhibitors of cation transport systems such as ouabain (Na(+)-K+ ATPase pump), bumetanide (Na(+)-K(+)-Cl- cotransport) or carbocyanine (Ca+(+)-activated K+ channel). Acidification and swelling of the erythrocytes are well known to be able to activate the K+ Cl cotransport; such conditions, which were demonstrated to occur during the storage, could lead to activation of the K+ Cl- cotransport in reinfused cells. These data strongly support the evidence that K+ Cl- cotransport plays a role in K+ loss and dehydration of stored erythrocytes, when incubated in autologous plasma.
