title: Glycopeptides of erythrocyte membranes in some hematological disorders.
abstract: Red cell membrane glycopeptides of subjects suffering from different hematological disorders (PNH, hemolytic anemias, dyserythropoietic anemias and polycythemia vera) have been characterized. 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.
