Стандартизованных способов оценки устойчивости к гипоксии экспериментальных животных и людей без гипоксического воздействия не существует. Поиск молекулярно-биологических маркеров, позволяющих выявить людей с различной устойчивостью к дефициту кислорода в условиях нормоксии или при умеренном гипоксическом воздействии, несомненно целесообразен. Возможно, что оценка исходной устойчивости к гипоксии позволит прогнозировать развитие и тяжесть течения заболеваний, механизмы которых связаны с кислородной недостаточностью. Одним из способов оценки устойчивости организма к гипоксии без воздействия в барокамере или в условиях гор может быть моделирование гипоксии in vitro. Цель исследования – охарактеризовать фагоцитарную активность моноцитов периферической крови у высокоустойчивых и низкоустойчивых к гипоксии крыс Wistar в условиях нормоксии, а также после гипоксического воздействия in vitro и in vivo. Устойчивость крыс к гипоксии определяли по «времени жизни» животных «на высоте» 11 500 м в барокамере. Через месяц после определения устойчивости к гипоксии одну группу крыс помещали в барокамеру на высоту 5000 м на 1 час для моделирования гипоксического состояния in vivo, а у другой группы крыс получали кровь из хвостовой вены для моделирования гипоксического состояния in vitro в условиях 1% кислорода в течение 1 часа. Проводили оценку фагоцитарной активности моноцитов периферической крови методом проточной цитофлуориметрии. Показано, что в условиях нормоксии у исходно высокоустойчивых и низкоустойчивых к гипоксии крыс фагоцитарная активность моноцитов не различалась. Фагоцитарная активность моноцитов после in vitro и in vivo гипоксического воздействия была выше у высокоустойчивых к гипоксии животных по сравнению с низкоустойчивыми. Увеличение фагоцитарной активности моноцитов по сравнению с условиями нормоксии наблюдалось только у высокоустойчивых крыс в условиях in vitro гипоксического воздействия. Полученные результаты свидетельствуют о том, что высокоустойчивые и низкоустойчивые к гипоксии организмы различаются по фагоцитарной активности моноцитов в условиях недостатка кислорода, что может определять течение воспалительных и опухолевых заболеваний. При поиске маркеров устойчивости организма к гипоксии целесообразно использовать моделирование гипоксии in vitro.</p></abstract><trans-abstract xml:lang="en"><p>It is known that there are individual differences in resistance to hypoxia, which can determine the predisposition to the development and severity of various diseases, including infectious, inflammatory and tumor. There are no standardized methods for assessing resistance to hypoxia in experimental animals and humans without hypoxic exposure. The search for molecular-biological markers, identifying people with different resistance to oxygen deficiency under normoxic conditions or under moderate hypoxic exposure is undoubtedly efficient. It is possible that the assessment of the basic resistance to hypoxia can help to predict the development and severity of the course of diseases, the mechanisms of which are associated with oxygen deficiency. One of the methods to assess organism resistance to hypoxia without exposure in a decompression chamber or in highland conditions can be modeling hypoxia in vitro. The aim of the study was to characterize the phagocytic activity of peripheral blood monocytes in tolerant and susceptible to hypoxia Wistar rats under normoxic conditions, as well as after hypoxic exposure in vitro and in vivo. The resistance of rats to hypoxia was determined by the gasping time at an altitude of 11.500 m in a decompression chamber. A month after determining the resistance to hypoxia, one group of rats was placed in a decompression chamber at an altitude of 5,000 m for 1 hour to simulate the hypoxic state in vivo. Blood from the tail vein of the other group of rats was placed in 1% oxygen for 1 hour to simulate the hypoxic state in vitro. The phagocytic activity of peripheral blood monocytes was assessed by flow cytometry. It was demonstrated that phagocytic activity of monocytes did not differ in tolerant and susceptible to hypoxia rats under normoxic conditions. The phagocytic activity of monocytes after in vitro and in vivo hypoxic exposure was higher in tolerant to hypoxia animals in comparison to susceptible ones. An increase in the phagocytic activity of monocytes compared to normoxia conditions was observed only in tolerant rats under in vitro conditions of hypoxic exposure. The obtained results indicate that tolerant and susceptible to hypoxia organisms differ in the phagocytic activity of monocytes under conditions of oxygen deficiency, which can determine the course of inflammatory and tumor diseases. The data obtained will be the basis for further experimental investigations organism hypoxia resistance markers.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>моноциты</kwd><kwd>фагоцитоз</kwd><kwd>in vitro</kwd><kwd>устойчивость к гипоксии</kwd><kwd>фагоцитарная активность</kwd><kwd>крысы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>monocytes</kwd><kwd>phagocytosis</kwd><kwd>in vitro</kwd><kwd>resistance to hypoxia</kwd><kwd>phagocytic activity</kwd><kwd>rats</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work was carried out  and  financed  under the budgetary topic 122030200530-6 “Cellular and molecular biological mechanisms  of  inflammation in the development of socially significant human diseases”</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Anand R.J., Gribar S.C., Li J., Kohler J.W., Branca M.F., Dubowski T., Sodhi C.P., Hackam D.J.
