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%).

Erythrocyte aggregability and AB0 blood groups
Clinical Hemorheology and Microcirculation, 2009It is not established whether there is an association between erythrocyte aggregation and AB0 blood type, as glycophorins carry sialic acid which is responsible for the negative erythrocyte surface charge and the antigenicity for AB0 blood groups. We have determined erythrocyte aggregation by means of the Myrenne aggregometer in 114 healthy volunteers,

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 ...

Animal species differences in erythrocyte aggregability
American Journal of Physiology-Heart and Circulatory Physiology, 1992Species differences in erythrocyte aggregability were investigated employing our whole blood erythrocyte aggregometer. Blood was sampled from seven species, including humans and anesthetized (30 mg/kg pentobarbital) animals. The erythrocyte aggregation rates were the following (in s-1): cats, 0.213 +/- 0.027 (means +/- SD); dogs, 0.164 +/- 0.027; men,

Erythrocyte deformability and erythrocyte aggregation in preeclampsia.
Clinical hemorheology and microcirculation, 2001One of the features of preeclampsia is impaired blood rheology due to altered erythrocyte aggregation and erythrocyte deformability. We investigated these two parameters which affect the viscosity of blood, along with serum and intraerythrocytic magnesium concentrations, immunoglobulin titres and fibrinogen concentration in 12 preeclamptic women ...

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.

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 ...
