For the induction of anxiety state, combined severe psychoemotional stress was applied (immobilization, forced swimming, ether stress followed 7 days later by repeated immobilization - restress). Correction of the anxiety state was achieved by application of hypoxic PC, which included three sessions of mild hypobaric hypoxia (360 mm Hg, 2 h, daily). The formation of the anxiety pathology was accompanied by a significant reduction in the expression of immunoreactive BDNF in dorsal (CA1) and ventral (dentate gyrus ) hippocampus and neocortex, while hypoxic PC resulted in partial (hippocampus) or complete (neocortex) restoration of BDNF expression. The results indicate that the neurotrophic factors, and BDNF in particular, seem to play an important role in the pathogenesis of the anxiety-depressive disorders as well as in mechanisms of proadaptive and neuroprotective effects of hypoxic PC.</p></abstract><trans-abstract xml:lang="ru"><p>Методом количественной иммуногистохимии исследованы изменения экспрессии нейротрофина BDNF (Brain-Derived Neurotrophic Factor) в гиппокампе и неокортексе 24 крыс-самцов линии Вистар при развитии у них постстрессорного тревожного состояния в экспериментальной модели посттравматического стрессового расстройства и его коррекции гипоксическим посткондиционированием (ПостК). Для индукции тревожного состояния применяли воздействие комбинированным психоэмоциональным стрессом (иммобилизационный стресс, вынужденное плавание, эфирный стресс и через 7 сут - повторная иммобилизация - рестресс). Коррекцию тревожного состояния у крыс проводили путем применения гипоксического ПостК - воздействия тремя сеансами умеренной гипобарической гипоксии (360 мм рт. ст., 2 ч). Установлено, что формирование тревожного состояния сопровождается значительной редукцией содержания иммунореактивного BDNF в дорсальном (СА1) и вентральном (зубчатая извилина) гиппокампе и неокортексе, а гипоксическое ПостК приводит к частичному (гиппокамп) или полному (неокортекс) восстановлению экспрессии BDNF. Результаты свидетельствуют о том, что нейротрофические факторы, в частности BDNF, очевидно, играют важную роль в патогенезе тревожно-депрессивных расстройств и реализации проадаптивного и нейропротективного действия гипоксического ПостК.</p></trans-abstract><kwd-group xml:lang="en"><kwd>BDNF</kwd><kwd>hippocampus</kwd><kwd>neocortex</kwd><kwd>post-traumatic stress disorder</kwd><kwd>BDNF</kwd><kwd>hypoxic postconditioning</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гиппокамп</kwd><kwd>неокортекс</kwd><kwd>посттравматическое стрессовое расстройство</kwd><kwd>гипоксическое посткондиционирование</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Рыбникова Е.
