[The role of the rheological parameters of erythrocytes in maintenance of the blood flow structure in stressed rats].
Analyzed were aggregation and deformation parameters of erythrocytes and their correlation in rats stressed by immobilization, cold, hunger, and cold combined with hunger, and their controls. Under the above experimental conditions, the aggregation rate of erythrocytes grows up without any pronounced changes in the deformation characteristics. There was a direct positive correlation between the aggregation and deformation parameters of erythrocytes under stress. It is assumed that this phenomenon represents a universal mechanism of adaptation of the blood viscosity regulation in mammals.
