Genetic differences in red cell osmotic fragility: analysis in allophenic mice

Genetic differences in red cell osmotic fragility: analysis in allophenic mice.

Mice of strain DBA/2J were found to produce red cells considerably more resistant to osmotic lysis than cells from C57BL/6J or the F1 hybrid between the two strains. Such strain-specific differences in osmotic fragility could be the result of genetically determined humoral or other systemic differences that indirectly influence red cell properties. Alternatively, this phenotypic variation might...

A microtechnique for measuring red cell osmotic fragility of infants.

Chloramphenicol (D-threo-2-dichloroacetamido-1-p-nitrophenylpropane-1,3-diol) added to blood samples did not alter the observed shift in the red cell osmotic fragility curves as the samples were aged in vitro for 24 hours at 37 degrees C. Nor was the normal rate of loss of 2,3-diphosphoglycerate, ATP, or glutathione from the red cells affected by the presence of chloramphenicol over the same pe...

III RESULTS OF TESTS FOR HAEMOLYSIS AND FOR OSMOTIC FRAGILITY OF RED BLOOD CELLS Osmotic Fragility

SYNOPSIS Nineteen patients with morphological abnormalities of the red blood cells are described, and these formed approximately 3 % of the total cases of cardiac valvular disease. In two patients the abnormal blood film developed after the insertion of an aortic and mitral valve prosthesis respectively, but in another two patients the abnormal blood film was corrected by aortic valve surgery. ...

Graphic analysis of osmotic fragility of erythrocytes.

A precise and highly reproducible method for analyzing the osmotic fragility of erythrocytes with a minute amount of blood (less than 10 mul) is described. The osmotic fragility curves are recorded with a coil planet centrifuge with accessories and a scanning photodensitometer. The recorded curves are transcribed by a DuPont Curve Resolver and their components are analyzed. Normal fragility cur...
