[Microcirculation in the skeletal muscle of the white rat subjected to deep immersion hypothermia and restored by self-warming].

The immersion hypothermia increased the blood flow at the initial stage, which was followed by a decrease in the capillary blood flow. In subsequent self-warming of the white rats the blood flow velocity was restored to practically initial values. No irreversible changes seem to occur in the rat muscle microcirculation system in a deep hypothermia.
