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 کاملCerebral blood flow imaging . Relation to blood rheology
A number of techniques allow imaging of the cerebral blood flow (CBF). Flow-sensitive time-of –flight (TOF) magnetic resonance imaging (MRI) demonstrates good representation of the flow but the extracranial hemodynamics could be assessed by color duplex ultrasound of the carotid arteries. Computerized tomography (CT), Xenon enhanced or CT perfusion with iodinated contrast, singlephoton emission...
متن کاملThe Rheology of Blood Flow in a Branched Arterial System.
Blood flow rheology is a complex phenomenon. Presently there is no universally agreed upon model to represent the viscous property of blood. However, under the general classification of non-Newtonian models that simulate blood behavior to different degrees of accuracy, there are many variants. The power law, Casson and Carreau models are popular non-Newtonian models and affect hemodynamics quan...
متن کاملBlood rheology in vegetarians.
1. Blood rheology has been quantified by measuring blood and plasma viscosity, packed cell volume (PCV), erythrocyte filterability and erythrocyte aggregation in forty-eight voluntary vegetarians and compared with matched controls. 2. Results show that in vegetarians, values for PCV were lower than those in controls, leading to reduced native blood viscosity. In addition PCV-standardized blood ...
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 ...
