[Changes in the parameters of the superfine structure of Mössbauer spectra of oxyhemoglobin in leukemia].

Evaluation of the Mössbauer spectra parameters of oxyhemoglobin (HbO2) from healthy people and patients with leukemia was carried out. An increase of quadrupole splitting (delta EQ) and isomer shift (delta) of HbO2 from diseased was observed. Within the framework of approximation made it was connected with the changes of ground and lowlying Fe2+ electronic states energy spectrum and with a decrease of the total electronic density on the 57Fe nucleus resulting from changes of Fe2+ bonds with axial ligands mainly.
