[Effect of mannitol on blood recirculation in the brain after interruption of the blood flow].

Premedication with mannitol before circulatory arrest not only promotes the reflow in the brain microvessels but also increases their diameters, thereby making more favourable conditions for blood supply of the brain after circulatory arrest. The data were obtained with the aid of automatic morphometry on microscopic slices of the dog brain perfused with Indian ink.
