title: [Changes in membrane proteins in the erythrocytes of patients with hemolymphoblastosis not directly involving the erythroblastic line].
abstract: An analysis of red cell membrane proteins in acute and chronic lymphatic leukaemia, Hodgkin's disease, lymphosarcoma, and myeloma was carried out. The electrophoretic pattern after solubilisation in urea or SDS was examined, along with migration on cellulose acetate or acrylamide in different buffers. Protein acid, basic and neutral amino acid percentages were also determined. An increase in low molecular weight and faster anodic migration proteins was noted in the lymphoblastoses, whereas the amino acid spectrum of these proteins showed percent changes in the case of some amino acids, particularly glutamic acid, phosphoserine, lysine and histidine. The alterations observed were compared with those noted previously in other haemoblastoses, congenital haemolytic and anhaemolytic blood diseases, and endoglobular or acquired metabolic defects in a closer assessment of their significance.
