[Possibility of the evaluation of the functional activity of human erythrocytes using the 31P-NMR method]

Intact human erythrocytes from venous blood were investigated. It has been found that the width and form of signals of 2.3 DFG vary strongly, but for the given person these characteristics of the signals are stable parameters. These variations were shown to correspond to the degree of inhomogeneity of erythrocytes population in venous blood as regards their relative concentrations of Hb and HbO2. The width of the signals of 2.3 DFG, so far reflects functional activity of the human red blood cells in oxygen transport.
