Osmotic fragility of erythrocytes in myopathies

Journal of Neurology, 1981
Erythrocytes taken from patients with myopathy have previously been reported to have increased osmotic fragility. We have examined the osmotic fragility of erythrocytes from patients with various myopathies and from carriers. The osmotic fragility was the same as in unaffected controls.

Osmotic fragility of premammalian erythrocytes

Comparative Biochemistry and Physiology, 1966
Abstract 1. 1. The degree of hemolysis in graded NaCl solutions (the osmotic fragility) was determined on blood from 35 premammalian vertebrates and from 9 mammals. 2. 2. Amphibian cells were the toughest, that, is the most resistant to hemolysis —lysing only in very dilute saline. 3. 3. Reptilian cells were the next resistant, measurable

Osmotic fragility of drug carrier erythrocytes

Research in Experimental Medicine, 1985
Erythrocytes have been proposed as biogradable cellular carriers for drugs. Potentials of this therapeutic approach are organ-specific targeting, protection and prolonged in vivo function of the encapsulated drugs. Previous studies demonstrated the advantage of a hypo-osmotic dialysis procedure for macromolecule loading resulting in cells that are ...

A Modification of the Erythrocyte Osmotic Fragility Test

American Journal of Clinical Pathology, 1970
A method for the determination of erythrocyte osmotic fragility using the Unopette and hepannized blood collected in Vacutainer tubes is described. The prepackaging of stable buffered solutions of sodium chloride with the use of self-filling, self-measuring capillaries for collection and dilution of blood makes the osmotic erythrocyte fragility test an

The influence of chlorpromazine on the osmotic fragility of erythrocytes

Biochemical Pharmacology, 1967
Abstract Protection of erythrocytes by chlorpromazine against osmotic haemolysis has been described before in the literature. This phenomenon has been investigated in some detail, in order to determine its physical chemical background. Experimental evidence is presented, indicating that the decrease of osmotic fragility is based on a drug induced ...

Increased erythrocyte osmotic fragility in pregnancy

American Journal of Obstetrics and Gynecology, 1982
An unexpected increase in erythrocyte osmotic fragility during pregnancy in two healthy women prompted a study of the effects of pregnancy on osmotic fragility. The incubated glycerol lysis time, a rapid, sensitive measure of osmotic fragility, was determined in 100 pregnant women and 50 nonpregnant control subjects.

Osmotic Fragility of Erythrocytes of Lemurs

Journal of Medical Primatology, 1981
Erythrocytes of five species of lemurs were found to be significantly more susceptible to lysis by osmotic stress than erythrocytes of man. In one lemur species, Lemur macaco, the red cell osmotic fragility profile resembles that of human subjects with hereditary spherocytosis.

Temperature effects on osmotic fragility, and the erythrocyte membrane

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1985
Results are reported on the temperature-dependence of intact-cell surface area, isotonic volume, hemolytic volume, and ghost steady-state surface area and volume, using several techniques of resistive pulse spectroscopy. Temperature was found not to alter the intact cell surface area permanently: the area remains constant at 130 +/- 1 micron 2, at ...

The effect of EDTA as an anticoagulant on the osmotic fragility of erythrocytes

Clinical & Laboratory Haematology, 1998
The osmotic fragility test is used to determine the extent of red blood cell haemolysis produced by osmotic stress. Since the quality of this test may easily be influenced by environmental and technical factors we have determined osmotic fragility reference values in our own conditions.
