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...
متن کاملOsmotic Fragility of Human Erythrocytes is Altered by Porphyrin Compounds
The chemical specificity of Porphyrin derivatives, Tetraphenylporphinesulfonate (TPPS), 5, 10, 15, 20-Tetrakis (4-sulfonatophenyl) porphyrinato Iron (III) Chloride (FeTPPS) and 5, 10, 15, 20-Tetrakis (4-sulfonatophenyl) porphyrinato Iron (III) nitrosyl Chloride (FeNOTPPS), on osmotic fragility of erythrocytes was examined in vitro. TPPS increased the osmotic fragility of erythrocytes more effec...
متن کاملEffect of parathyroid hormone on osmotic fragility of human erythrocytes.
The survival of erythrocytes (RBC) is shortened in uremia, and it has been shown that calcium influx into RBC evoked crenation and increased their rigidity. The high blood levels of parathyroid hormone (PTH) may augment entry of calcium into RBC and hence affect their integrity. We examined the effect of PTH on osmotic fragility of human RBC and investigated the mechanisms through which PTH int...
متن کاملOsmotic fragility of erythrocytes in Duchenne muscular dystrophy.
Osmotic fragility of erythrocytes was studied in ten Duchenne dystrophic patients and eight healthy controls. Lysis started in Duchenne crythrocytes at a concentration of 6.5 g/l NaC1 and in the control erythrocytes at a concentration of 5.5 gIl NaCI. At all concentrations of sodium chloride (from 6.5 g/l to 4.5 g/l) significantly greater lysis was observed in the erythrocytes of dystrophic pat...
متن کاملAge as Affecting the Osmotic and Mechanical Fragility of Dog Erythrocytes Tagged with Radioactive Iron
Radioactive iron was administered to three normal dogs, two of which had previously been bled, in order to tag a group of erythrocytes of approximately known age. The osmotic fragility of the newly formed tagged cells was significantly greater than that of the general cell population during the first few days after injection of the iron, while the mechanical fragility of the young cells was les...
