[Changes in the proteins of erythrocyte membrane in polycythemia vera].

Red cell membrane protein behaviour was studied in patients with polycythaemia vera, polyglobulia secondary to cardiorespiratory disorders, chronic myeloid leukaemia and acute granuloblastic leukaemia. Electrophoretic pictures were examined after solubilisation in urea or SDS and on various supports. Chromatographic analysis was also made of acid, neutral and basic amino acids obtained by hot-acid hydrolysis of the stromas. Protein electrophoretic changes in polycythaemia differed from those observed in granuloblastic leukaemia and chronic cor pulmonale. Different stromal protein amino acid percents were also noted, with marked variations between each disease.

[Changes in membrane proteins in the erythrocytes of patients with hemolymphoblastosis not directly involving the erythroblastic line].

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.

[The central nervous system and inflammation: the role of opioid peptides].

Inhibition of human granulocyte aggregation was observed in the presence of morphine in a naloxone stereoselective way, while the opioid peptides were ineffective. In comparative studies Ca(+)+ (A23187) and dynorphin 1-9, per se, induced stimulation of arachidonic acid metabolites from granulocytes. In this regard dynorphin 1-9 may function as a mediator between the central nervous system and the inflammation.
