title: The activity of glucose-6-phosphate dehydroxygenase and glutathione enzymes in red blood cells in patients with haemoblastoses.
abstract: The activity of glucose-6-phosphate dehydrogenase (G6PD), glutathione reductase (GSSG-R), glutathione peroxidase (GSH-Px) and MDA levels have been assayed in red blood cells (RBC), obtained from 57 people suffering from haemoblastoses. The activities of G6PD in the RBC in patients with polycythemia vera (PV) and chronic lymphoid leukemia (CML) are significantly higher than those in healthy patients. Changes in the activity of glutathione dependent enzymes GSSG-R and those of GSH-Px in the RBC go in opposite directions: the activity of GSSG-R is significantly enhanced in patients with PV and CML, but the activity of GSH-Px is decreased in all patients suffering from haemoblastoses. The high levels of MDA in the RBC of all patients with haemoblastoses indicate intensification of lipid peroxidation in their RBC.
