The influence of erythrocyte aggregation on induced platelet aggregation
Clinical Hemorheology and Microcirculation, 2010Red blood cells (RBCs) affect platelet aggregation in flowing blood (primary hemostasis). We tested the hypothesis that RBC aggregation could influence platelet aggregation. RBC aggregation was altered in vitro by: (i) changing plasma aggregatory properties with 3.7 g% dextran 40 (D40), 3.0 g% dextran 70 (D70) or 1.55 g% dextran 500 (D500);

Ultrasound Backscattering from Non-Aggregating and Aggregating Erythrocytes-A Review
Biorheology, 1997The objective of the present paper is to provide a detailed review of theoretical, experimental and clinical works aimed at understanding the scattering of ultrasound by red blood cells (RBC). The paper focuses on the role of biofluid mechanics and blood biorheology on the scattering mechanisms.

Thrombosis Research, 1996
Intravascular thrombus formed under low shear conditions consists of red cells enmeshed within a fibrin network. Since red cells reduce the permeability of fibrin network by surface drag and by volume occupancy the significance of red cell aggregability and deformability in network permeability needs examination.

Hematocrit dependence of erythrocyte aggregation
Clinical Hemorheology and Microcirculation, 1988We studied hematocrit, erythrocyte aggregation index and plasma fibrinogen level in 19 healthy subjects. We measured erythrocyte aggregation both on native blood and on washed erythrocytes resuspended in their own autologous plasma or serum. We found a significant negative linear correlation between hematocrit and the erythrocyte aggregation index on ...

New aspects of erythrocyte aggregation
Clinical Hemorheology and Microcirculation, 1988We studied blood and plasma viscosity, hematocrit, erythrocyte aggregation index and plasma protein fractions in 26 healthy subjects. We found a significant positive linear correlation between hematocrit and blood viscosity at each of the considered shear rates (low shear range), and a significant negative linear correlation between hematocrit and ...

Metabolic depletion decreases the aggregability of erythrocytes
Clinical Hemorheology and Microcirculation, 2011We studied the influence of metabolic depletion on red blood cell (RBC) aggregability, which is a determinant of blood flow. Heparinized blood was stored at room temperature for 0, 24, and 48 h. RBCs were washed twice and resuspended in Tris-buffer containing 3% dextran 70 (hematocrit 30%).

Polymicroviscometry (PMV) and erythrocyte aggregation
Clinical Hemorheology and Microcirculation, 1989The process of red blood cell (RBC) aggregation is always associated with its counterpart: phase separation. The possibility of predicting the occurrence of a specific hemodynamic effect produced by these two processes in the living vasculature is frequently limited by insufficient information on the ...

Viscometric quantification of erythrocyte aggregation
Clinical Hemorheology and Microcirculation, 1989Linking between blood viscosity and erythrocyte aggregation is interpreted as resulting of structural changes of red blood cell aggregates and their clusters, in the absence of blood flow. Limits of applying such an interpretation is discussed with the help of few examples.
