A charge of the erythrocyte test by automated method

Abstract

New methods of an automated evaluation of the blood rheological parameters: 1) the viscosity, 2) electric conductivity and 3) the charge of erythrocytes have been theoretically and experimentally substantiated by way of registering the Q-factor of the tuned-circuit, containing a capillary with the blood flow. A design of an electronic measuring complex is based on modeling the physical blood conditions in the natural environment

Analysis of Red Blood Cell Movement in Whole Blood Exposed to DC and ELF Electric Fields

“…Both the first and third terms are proportional to the electric field intensity. Using general blood parameters ( Q = −3.19 × 10 −10 C, r = 2.70 × 10 −6 m, η = 1.58 × 10 −3 Pa·s, ζw = −15.7 × 10 −3 V) [Gudmundsson and Bjelle, 1993; Gutsul et al, 2012; Tokumasu et al, 2012; Zhbanov and Yang, 2015], the ratio of μ EP to μ EO is estimated as on the order of 10 6 . In other words, the mobility of electrophoresis is much greater than that of electroosmosis.…”

Quantitative analyses of RBC movement in whole blood exposed to DC and ELF electric field

“…Because of the high conductivity in vivo, extremely large gradients in electric field are unlikely in a living body. Therefore, under general blood parameters ( Q = −3.19 × 10 −10 [C], r = 2.70 × 10 −6 [m], η = 1.58 × 10 −3 [Pa･s]) (Gudmundsson & Bjelle, 1993; Gutsul et al, 2012; Tokumasu et al, 2012; Zhbanov & Yang, 2015), the electrophoresis is overwhelmingly large. Therefore, electrophoresis is regarded as dominant under DC electric field exposure.…”
