[Disorder and restoration of the microcirculation in the brain of rats under deep hypothermia]

Sharp deceleration of the brain microcirculation in deep hypothermia (up to 16-18 degrees C in the rectum) is due to no irreversible alterations in the microcirculation system. Physiological controlling mechanisms of this function are preserved and help to restore the velocity of the capillary blood flow in the course of warming up of the animal.
