Abstract

Concentration of malonic dialdehyde (MDA) and activity of antioxidant enzymes G-6-PD, glutation peroxidase (GP), glutation reductase, catalase, superoxide dismutase were measured in red cells of patients with polycythemia vera. Plasmic ions Fe3+ were estimated by means of electron-paramagnetic resonance. MDA concentration and antioxidant enzymes (except GP) in polycythemia red cells were found increased, while the activity of selenium-dependent GP was reduced, the inhibition being greatest in severe iron deficiency. It is suggested that GP activity in red cells depends on both selenium levels in the body and concentrations of non-hematic iron.
