Relationship between electrophoretic mobility of erythrocytes and blood erythrocyte count in rats

A significant curvilinear relationship was found between erythrocyte count in rat blood and electrokinetic characteristics of these cells. Electrophoretic mobility of erythrocytes remained unchanged, slightly increased, or decreased with increasing cell count in the vascular bed depending on animal state. Excessive increase in the number of erythrocytes was accompanied by accumulation of cells with low electrophoretic mobility in the electric field.

Effect of blood reticulocyte concentration on electrophoretic mobility of erythrocytes in rats

In intact rats electrokinetic characteristics of erythrocytes weakly depended on the intensity of erythropoiesis. This dependence became significant when the degree of erythropoiesis approached the upper limit of variations. Electrophoretic mobility of erythrocytes progressively decreased with increasing blood reticulocyte count. Subpopulations of erythrocytes with low mobility in electric field accumulated in the blood. Our results indicate that erythrocytes whose electrokinetic potential is similar to the mean mobility of circulating cells migrate from the bone marrow into the circulation under normal conditions.

Electrokinetic behavior of rat blood erythrocytes: dependence on cell volume

The interrelationship between electrophoretic mobility and the volume of rat blood erythrocyte is described by a non-linear curve, where the deviation of cell volume from the physiological normal is accompanied by a decrease in their mean electrophoretic mobility. In some ranges, the deviations of erythrocyte volume do not affect their electrokinetic properties. It can be hypothesized that the simultaneous shifts of these parameters are caused only by some hematological abnormalities that are manifested in pronounced changes in cell homeostasis.

Relationship between erythrocyte count and volume in humans and rats

The mean corpuscular volume and concentration of blood erythrocytes in intact male rats are inversely related in the entire fluctuations range. In healthy men and women the correlation between these parameters is described by a parabola with alternating zones of positive and negative relationships. These covariations are unstable; in disease they change and sometimes are transformed into monotonous reciprocal correlations.
