Blood Viscosity: Influence of Erythrocyte Aggregation
Science, 1967The addition of purified canine or bovine fibrinogen to suspensions of canine erythocytes in Ringer solution caused an increase in viscosity and the formation of aggregates of erythocytes. Both of these effects became increasingly pronounced as the fibrinogen concentration was raised, and they approached plateaus with 1 gram of fibrinogen ...

The influence of fractions of abnormal erythrocytes on aggregation
European Journal of Clinical Investigation, 1991Abstract. Erythrocytes with abnormal shapes and deformability reduce cell aggregation and hence sedimentation. It is not known what influence small fractions of these abnormal cells have on the sedimentation behaviour of normal cells. We have used three different methods to alter erythrocyte properties (glutaraldehyde, heat treatment, and metabolic ...

Effect of pH on the velocity of erythrocyte aggregation
Biorheology, 1988The effect of pH on the velocity of aggregation of human erythrocytes was quantitatively examined with a rheoscope combined with a video-camera, an image analyzer and a computer, in relation to the morphological changes of erythrocytes and their aggregates. (i) With increasing pH of the medium, the velocity of erythrocyte aggregation increased.

Ultrasonic evaluation of erythrocyte aggregation dynamics
Biorheology, 1989The dynamics of aggregation and disaggregation of blood of varying hematocrit in oscillatory flow in a distensible horizontal tube was determined by measuring the developing echo intensity of the blood samples with a 10 MHz B-mode ultrasonic scanner. Early aggregation could be detected within 10 sec. of stoppage of flow.

Aggregate formation of erythrocytes in postcapillary venules
American Journal of Physiology-Heart and Circulatory Physiology, 2005The purpose of the present study was to obtain information on erythrocyte aggregate formation in vivo. The movements of erythrocytes in postcapillary venules of the rat spinotrapezius muscle at various flow rates were recorded with a high-speed video camera before and after infusion of dextran 500. To distinguish aggregates, the following criteria were

Erythrocyte aggregation during normal pregnancy
American Journal of Obstetrics and Gynecology, 1983Red blood cell aggregation induced by fibrinogen is a major determinant of the non-Newtonian flow behavior of blood and has been suggested as a possible contributing factor for thrombogenesis. Given the elevated fibrinogen levels and the incidence of thrombotic accidents in pregnancy, a study was designed to assess red blood cell aggregation at ...

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.

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.

Erythrocyte aggregation: Basic aspects and clinical importance
Clinical Hemorheology and Microcirculation, 2013Red blood cell (RBC) aggregate to form two- and three-dimensional structures when suspended in aqueous solutions containing large plasma proteins or polymers; this aggregation is reversible and shear dependent (i.e., dispersed at high shear and reformed at low or stasis).
