CHANGE DUE TO AGING OF POTASSIUM CONTENT, CARBONIC ANHYDRASE AND HEMOLYSIS OF THE COLD STORED HUMAN ERYTHROCYTE, AND EFFECT OF SOME GLUCIDES, THIOL COMPOUNDS AND ADENOSINE TRIPHOSPHATE ON THEM

Abstract

As well known, the stored erythrocytes deteriorate rapidly, while the plasma can be kept undenatured for a while. Using the human erythrocytes suspended in the phosphate buffered saline solution and stored in the refrigerator at 5°C, we have investigated change of its potassium content, carbonic anhydrase activity and hemolysis in terms of the time of storage, and effect on them of glucides, thiol compounds and adenosine triphosphate added to the suspension.
