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 کاملEffects of nitric oxide on red blood cell deformability.
In addition to its known action on vascular smooth muscle, nitric oxide (NO) has been suggested to have cardiovascular effects via regulation of red blood cell (RBC) deformability. The present study was designed to further explore this possibility. Human RBCs in autologous plasma were incubated for 1 h with NO synthase (NOS) inhibitors [N(omega)-nitro-l-arginine methyl ester (l-NAME) and S-meth...
متن کاملPlasmodium falciparum maturation abolishes physiologic red cell deformability.
Normal red cells deform markedly as they pass through the spleen and the peripheral capillaries. In these studies, the effects of Plasmodium falciparum infection and maturation on the deformability of parasitized red cells exposed to fluid shear stress in vitro were examined by means of a rheoscope. Red cells containing the early (ring) erythrocytic stage of the parasite have impaired deformabi...
