title: Alterations in rheologic properties of stored blood as criterion of the functional state of erythrocytes in haemocarboperfusion.
abstract: Rheologic studies performed on rotational viscometers "Rheotest-2" and "VIR-78" within shear rates gamma interval of 0.1 s-1 less than gamma less than 1,312 s-1, revealed a substantial reduction in dynamic viscosity of the blood subjected to sorption treatment on activated charcoal. The importance of volume concentration of erythrocytes proper for dynamic viscosity is analysed. Special emphasis is placed on the necessity to take into account the dispersion of electrophoretic mobility of erythrocytes in analyzing surface properties of erythrocytes from stored blood before and after hemocarboperfusion. In addition, the normalization of electrosurface characteristics of erythrocytes and associated with them the aggregational property of blood after its purification by sorption is demonstrated. The restoration of the explored physical and chemical characteristics of blood, perfused through the sorbent, permits its more valuable transfusional medium to be considered in comparison to conventional stored blood with identical times of preservation.
