A study was made on the red cell membrane glycopeptides of subjects suffering from different hematologic disorders: paroxysmal nocturnal hemoglobinuria (PHN), hemolytic anemias, dyserythropoietic anemias and polycythemia vera. In most cases, except in polycythemia vera, a decrease of sialic acid and galactosamine was detected. The role of these alterations is discussed with regard to the decrease of membrane glycopeptides during physiological aging of the red cell.
