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...
متن کاملIII 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. ...
متن کاملA Rapid Micro Method for Recording Red Cell Osmotic Fragility by Continuous Decrease of Salt Concentration.
A single volume of 0.075 ml. of a 1 in 10 dilution of whole blood in isotonic NaCl solution is introduced into a container cell, two walls of which are made of a dialysing membrane. The container cell is introduced into a test tube of distilled water, placed in an instrument which is essentially a colorimeter with a recorder, between the source of light and the photoelectric cell. Dialysis thro...
متن کاملGenetic 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...
متن کاملIndividual Osmotic Fragility Distribution: A New Parameter for Determination of the Osmotic Properties of Human Red Blood Cells
The aim of our experiments was to characterise and to validate the osmotic fragility test when applied to human blood samples with no significant alterations of osmotic fragility but with a differentiating shape of the haemolysis curve. All experiments were carried out on human erythrocytes taken from the Regional Centre of Blood Donation and Blood Therapy in Wrocław. The washed erythrocytes we...
