Abstract:
The resistivity of blood fiom patients with cerebral vascular disease, anticoagulated with dried .sodium heprin, were investigated. The results showed that the resistivity of blood is found to increase linearly as the haemetocrit level increase from 35% to 51% at a fixed temperature of 37℃ and measuring fiequency 1.5 kHz. The regression equation was p=3.09Hct+7.13, (r=0.992).The influence of fibrinogen on the resistivity might partly be the result of interfacial polarization and red cell rouleaux formation.
