Deformation of erythrocytes by trypanosomes

Experimental Cell Research, 1965
The movements of Trypanosoma brucei are briefly described. The deformation of mouse erythrocytes by this organism is illustrated and the magnitude of the deforming force calculated.

Erythrocytes deformability and diabetes

Clinical Hemorheology and Microcirculation, 1983
A large scale study of the erythrocyte deformability in diabetes is presented. The initial filtration flow rate method is used on diluted (white blood cells reduced) RBC suspensions. The rigidity index thus obtained, IR, is largely insensitive to the filter plugging.

Erythrocyte deformability and erythrocyte aggregation in preeclampsia.

Clinical hemorheology and microcirculation, 2001
One 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 ...

Physico-chemical factors of erythrocyte deformability

Biorheology, 1985
The aim of this study is to assess the role of different physicochemical factors on the deformability measurements by using the initial filtration flow rate method, and to differentiate between the membrane or internal origin of some rigidity changes. The deformability is maximum for the physiological pH value and it decreases sharply for hypotonic and

Reduced Erythrocytic Deformability in Megaloblastic Anemia

American Journal of Clinical Pathology, 1976
Ten patients with megaloblastic anemia had erythrocytes with reduced deformability. The mean half-life for erythrocyte filtration was 9.89 minutes in these patients, compared with 5,20 minutes in controls. The half-life was inversely related to the hemoglobin concentration. After adequate vitamin replacement therapy filtrability improved significantly.

Erythrocyte Deformability in Uremic Hemodialyzed Patients

Annals of Internal Medicine, 1973
Abstract Erythrocyte deformability was measured in normal people and in patients with chronic renal failure treated with hemodialysis.

Erythrocyte Deformation in Human Muscular Dystrophy

Science, 1974
Erythrocytes from patients with congenital muscular dystrophy exhibit dramatic surface deformation when observed with a scanning electron microscope. A similar alteration, but one affecting a smaller proportion of cells, occurs in the case of female carriers of the sex-linked Duchenne dystrophic condition.

Microscopic investigation of erythrocyte deformation dynamics

Biorheology: The Official Journal of the International Society of Biorheology, 2006
The understanding of erythrocyte deformation under conditions of high shear stress and short exposure time is central to the study of hemorheology and hemolysis within prosthetic blood contacting devices. A combined computational and experimental microscopic study was conducted to investigate the erythrocyte deformation and its relation to transient ...

Blood Viscosity: Influence of Erythrocyte Deformation

Science, 1967
Suspensions of canine and human erythocytes hardened with acetaldehyde differ from the suspensions of normal erythrocytes with respect to their rheological behavior. Normal erythrocytes can be packed by centrifugation so that the sediment volume is nearly 100 percent cells, but the hardened erythrocytes (RBC's) can be packed only to approximately 60 ...

Reduced erythrocyte deformability alters pulmonary hemodynamics

Journal of Applied Physiology, 1989
Isolated rat lungs were perfused with suspensions containing normal and stiffened erythrocytes (RBCs) to assess the effect of altered RBC deformability on pulmonary hemodynamics. RBC suspensions were prepared using cells previously incubated in isosmolar phosphate-buffered saline with or without 0.0125 or 0.01875% glutaraldehyde.
