[The effect of massive blood loss on the adrenaline-sensitive pool of the blood neutrophils].

Experiments were conducted on models of immobilization stress and hemorrhagic shock in rabbits to study the changes in the ability of intravenously injected adrenaline (A) to induce blood neutrophilia due to the escape of parietal neutrophils into circulation. It is shown that immobilization stress, just like A infusion, leads to neutrophilia. In contrast, in hemorrhagic shock neutropenia develops and the response to A disappears.
