[Characteristic features of erythrocyte aggregation in different animals and in man]

The reversible erythrocytes aggregation is considered to be a basic microrheological process determining a number of microcirculation features. But the problem of the adaptive role of erythrocytes aggregation still needs elucidation. The markedness of erythrocytes aggregation was compared in mammals occupying different positions in the evolutionary systematics: in 62 animals of 10 species and in 25 healthy humans. The species features of the erythrocytes aggregation were altered by means of adding high--molecular polyoxyethylene to blood plasma. The data obtained gave evidence on species differences in the erythrocytes aggregation, specifics of cell membrane, differences in the latter's electrostatic charge.
