Erythrocyte rheology.
Erythrocyte deformability was formerly measured by its contribution to whole blood viscosity. It is now more commonly measured by filtration of erythrocytes through, or aspiration into, pores of 3-5 microns diameter and by the measurement of shear induced erythrocyte elongation using laser diffractometry. Recent improvements in the technology for erythrocyte filtration have included the removal...
متن کاملBlood Rheology Aspects of the Microcirculation
To elucidate the basis for the drop in pressure from large artery to vein, Jean Léonard Marie Poiseuille (1797-1869) undertook a series of seminal studies that defined the laws of fluid flow in tubes of uniform cross-section and that identified the microcirculation as the major site of the resistance to flow [1, 2]. While best known for his meticulous experimental studies of viscous flow in gla...
متن کاملThe importance of carnosine to erythrocyte rheology
Carnosine is a naturally occuring multifunctional dipeptide made up of a chemical combination of the amino acids beta-alanine and L-histidine.It commonly presents in mammalian tissues, in especially high levels in long-lived cells (e.g.nerve and muscle), but it declines with age. Its main physiological function is uncertain although many possibilities have been proposed including physiological ...
متن کاملCarnosine and Its Role on the Erythrocyte Rheology
Erythrocytes are the most abundant cells (around 5 million/mm3) in the body. The main function of these specialized cells is transport of oxygen (O2) and mediation of carbondioxide (CO2) production (Volpe, 1993). Mature erythrocytes have no capacity for cell division, protein synthesis, and mitochondrial-based oxidative reactions (Bunn, 1991; Benz, 2010). The erythrocyte possesses more membrane...
متن کاملThe importance of erythrocyte aggregation in blood rheology: considerations on the pathophysiology of thrombotic disorders.
To the Editor: EA. However, the exact mechanism(s) of elevated EA in the pathogenesis of thrombotic disorders have not been fully established yet and further studies are required to elucidate them. I believe I have read with great interest the review by Kroll et al on platelets that at present, a preferably nonpharmacological approach on the and shear stress. They state that rheologic factors l...
