[Kinetics of decrease in erythrocyte filterability under the effect of ephazol].
The effect of palladium-containing complex Ephazol on the filtration rate of erythrocyte suspensions through nuclear filters was studied by the constant-pressure filtration method. It was shown that the filterability of red blood cells incubated with ephazol decreased. If the time necessary for a fixed volume of red blood cell suspension to pass through a filter was plotted against the time of incubation with Ephazol or against its initial concentration, the curves typical of autoaccelerated processes were obtained. From analysis of kinetic models, it was concluded that the effects observed are due to the nonlinear dependence of the filtration rate w on the rate at which an erythrocyte passes through a pore and the influence of Ephazol on the distribution of erythrocytes with respect to w. Several models describing changes in the distribution of erythrocytes with respect to w in the presence of Ephazol and possible mechanisms relating the filtration kinetics to the incubation parameters are discussed.
