Erythrocyte deformability in aging

Mechanisms of Ageing and Development, 1984
Blood viscosity and the deformability and other properties of erythrocytes were compared among 60-, 150-, 320- and 710-day-old rats. Blood viscosity was remarkably higher in the 320- and 710-day old rats than in those 60- and 150 days' old. Measurement by the capillary centrifugal method showed that the deformability of erythrocytes is significantly ...

Deformation of Erythrocytes in Microvessels and Glass Capillaries: Effects of Erythrocyte Deformability

Microcirculation, 1996
ABSTRACTObjective: The deformation of erythrocytes in microvessels less than 15 μm in inner diameter was analyzed using a microvascular bed isolated from rabbit mesentery. The deformation was compared with that found in glass capillaries.Methods: Human erythrocytes were perfused through two media: first, a microvascular‐bed section isolated from rabbit

Reduced Erythrocyte Deformability in Diabetes

Diabetes, 1978
The flow properties of individual erythrocytes have been studied in glass micropipets 4 μ internal diameter. The pressure gradient required to establish a standard oscillatory movement over a 130-μ path in a three-second time period was measured in paired studies comparing diabetic and control erythrocytes suspended in Ringer solution.

Deformed erythrocytes in muscular dystrophies

Neurology, 1978
Because of previous reports of a possible correlation between echinocytogenesis and muscular dystrophies, we investigated the time-dependent development of echinocytes in the blood of normal subjects, patients, and healthy carries of Duchenne dystrophy. There was a quantitatively significant increase of echinocytes in patients and carriers.

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.

Effects of Buflomedil on Erythrocyte Deformability

Angiology, 1981
This brief communication outlines re cent experiments on the effects of buflo medil, a new vasoactive agent, on red cell deformability in patients with leg ischemia. In this randomized, double-blind cross-over study, 10 patients received 200 mg buflomedil and matching placebo intravenously.

Deformation behavior of erythrocyte ghost

Biopolymers, 1969
AbstractBiological membranes consist mainly of lipids and proteins. At present, the structure of the lipid phase appears to be established, but hypotheses on the molecular organization of the protein are difficult to support. Thus the deformation behavior of whole human erythrocyte ghosts, ghosts after the selective removal of lipids and ghosts ...

Decreased deformability in aging erythrocytes

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1982
Deformability of bovine erythrocytes separated according to density (and age) was estimated by a modified Teitel's filterability test, the centrifugational test of Sirs, and viscosity measurements of cell suspensions. Both youngest and oldest erythrocytes were found to be less deformable than middle-aged cells, a result speaking against any chief role ...

Erythrocyte deformability in diabetes and erythrocyte membrane lipid composition

Metabolism, 1990
Erythrocyte deformability was assessed in 40 diabetic patients, 24 insulin-dependent (IDD) and 16 non-insulin-dependent (NIDD), by measuring the initial filtration flow rate of whole blood, isolated red blood cells (RBC), and isolated RBC membranes with the Hanss hemorheometer, and its relationship to the plasma and ghost membrane lipid composition was

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 ...
