Abstract

Laser Doppler measurements of blood flow velocities in the vessels of rat mesentery have been performed to study the effect of the drag-reducing agent polyethylene oxide Polyox WSR-301 on microcirculation. These agents are capable of increasing the cardiac output and decreasing the arterial pressure. Measurements performed on spontaneously hypertensive rats anesthetized by Nembutal showed that the mean blood velocities in all groups of studied vessels are higher (by nearly two to three times) as compared to those in controls. Most likely these results reflect the effects of hypertensive raising pressure drop and the `rarefaction' phenomenon.
