[Hypoxic postconditioning corrects behavioral abnormalities in a model of post-traumatic stress disorder in rats].
Protective effects of the novel technique of hypoxic postconditioning with a hypobaric hypoxia paradigm were studied in "stress-restress" model ofposttraumatic stress disorder in rats. It was shown that repeated (3 times) exposure of rats that survived after severe traumatic stress to mild hypobaric hypoxia (postconditioning mode) efficiently abolished the development of stress-induced anxiety state. Postconditioning had a clear anxiolytic effect both when it was delivered after traumatic stress and after restress, but the intensity of this effect depended on the period ofpathogenesis of the posttraumatic stress disorder, when postconditioning was given. The results indicate that suggested postconditioning model with repetitive mild hypobaric hypoxia exerts potent anxiolytic and stress-protective action.
