Red cell membrane deformability: new data.
Red cells arrested by fine fibers and subjected to drag forces in a moving stream of fluid can be stressed beyond the point of rupture. The technique, which is basically an in vitro analogue of the microangiopathic hemolytic state, thus permits a study of red cell behavior over the entire range of stress that the membrane can withstand. Measurements made by this approach show an exponential rel...
متن کاملMetabolic dependence of red cell deformability.
The contribution of the metabolic state of human erythrocytes to maintenance of cellular deformability was studied during and after in vitro incubation in serum for periods up to 28 hr. An initial loss of membrane deformability became apparent between 4 and 6 hr when cellular adenosine triphosphate (ATP) levels were approximately 70% of initial values. Membrane deformability then remained stabl...
متن کاملAnalyzing red blood cell-deformability distributions.
BACKGROUND Red blood cells (RBCs) must deform to pass the smallest capillaries of the microcirculation. Available techniques for measuring RBC deformability often provide an indication of the mean deformability. The latter may be decreased either by a slight overall deformability reduction or by the presence of a small fraction of rigid cells. A distinction between these two cases can be made w...
متن کاملCEREBROSPINAL FLUID FINDINGS IN NEONATAL BACTERIAL MENINGITIS
Background : Meningitis is more common during the neonatal period than other periods of life and has a prevalence of one in 1000 live births. The similarity of its clinical manifestations with other infectious diseases makes it difficult to diagnose. The aim of the current study was to determine the relationship between age, sex, clinical signs and symptoms and laboratory test results of ne...
متن کاملMeasuring Deformability and Red Cell Heterogeneity in Blood by Ektacytometry.
Decreased red cell deformability is characteristic of several disorders. In some cases, the extent of defective deformability can predict severity of disease or occurrence of serious complications. Ektacytometry uses laser diffraction viscometry to measure the deformability of red blood cells subject to either increasing shear stress or an osmotic gradient at a constant value of applied shear s...
