Abstract

Simultaneous temporal analysis of whole human or rat blood luminescence and erythrocytes sedimentation rate (ESR) in same blood using special computerized optoelectronic devices for single photon counting and for high temporal resolution of the rate of sedimentation of red blood/plasma boundary revealed correlation between both time series. Correlation was observed in vitro in normal blood, after action of physical (height of blood column) and of chemical (hydrogen peroxide) factors, and in experimental cerebral ischemia. An ischemia was invoked in rats by occlusion of both common carotid arteries. ESR was studied with the device “ESR-scan” and the dynamics of respiratory burst (RB) by a luminol-dependent luminescence method on the same blood samples. There was a noticeable increase of intensity of RB in whole rat blood and significant acceleration of ESR in blood diluted on 50% in 90 minutes after applying a ligature on carotid arteries. The individual differences between animals attesting to different degree of RB and ESR activation in blood both in intact animals and after operational intervention was obtained. Revealed correlation points to considerable relation between blood energy and it’s mechanical properties.
