Filtration of platelet-rich heparinized plasma deprived lymphocytes and contained lymphocytes was investigated in 21 donors. Filtration of both plasmas was performed through 5 microns-pore nuclear filters at the constant perfusion pressure 100 cm H2O. The plasma contained lymphocytes filtered by 80% better, than the lymphocyte-deprived plasma.

We investigated blood cells suspension filterability of 16 donors. The filtration was performed trough 5 microns-pore nuclear filters at constant perfusion pressure 10(5) din/cm2. We estimated also the adherence of leukocytes and platelets on nylon.

The blood filtration was performed through 5 m pores of nuclear filters at constant perfusion pressure 100 cm H2O. Erythrocytes didn't influence on the leukocyte filtration in blood.

As many as 45 patients with multiple sclerosis were examined for rheological blood properties. As compared to controls, the group under examination manifested the rise of plasma viscosity, acceleration of red blood cell aggregation. 26.

The blood was filtered through a filter with pore diameter of 5 microns under a pressure of 100 cm water column. Blood filterability drastically deteriorated if leukocyte concentrations in the blood increased and depended on the leukocyte filtration characteristics.

A 25% decrease in filterability and elevated erythrocyte cholesterol/phospholipid ratios were found in anginal patients, as compared to normal subjects. A close inverse correlation (r = -0.

It is suggested that erythrocyte microrheologic disorders are related to excessive cellular cholesterol content in coronary patients.
View Article and Find Full Text PDFA study of 80 anginal patients showed their platelet molar cholesterol/phospholipid ratios, platelet membrane microviscosity, membrane release of calcium and fatty acids, and platelet aggregation capacity to be elevated. It is assumed that excessive platelet cholesterol has a significant effect on platelet aggregation, that is mediated by the intraplatelet processes examined, in anginal patients.

Electronic paramagnetic resonance was used to study the structural and functional properties of platelets from patients with coronary heart disease. It was established with the use of the spin probe 5-doxylstearate that cytoplasmic platelet membranes of coronary heart disease patients are marked by a higher molecular packing as compared to normal. The rate of platelet aggregation studied independently of plasma factors appeared also higher, with a direct correlation being discovered between the aggregation properties and viscosity of platelet membranes.
