Исследование микроциркуляторного звена как элемента сердечно-сосудистой системы применительно к космической медицине актуально как для выявления адаптационных изменений к невесомости, так и поиска новых диагностических критериев оценки функционального состояния организма космонавта в перспективе дальних космических полетов.</p></sec><sec><title>Цель</title><p>Цель. Изучение микрокровотока и его регуляции в различных областях кожи у здоровых добровольцев в условиях 21-суточной антиортостатической (–6°) гипокинезии (АНОГ).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В эксперименте приняли участие 6 мужчин-добровольцев в возрасте 26–34 лет. Для моделирования транслокации жидких сред и гиподинамии испытуемые находились в антиортостатическом положении в течение 21 сут Микроциркуляцию исследовали с помощью метода лазерной доплеровской флоуметрии с использованием портативных лазерных анализаторов «ЛАЗМА ПФ» (ООО НПП «ЛАЗМА», Россия). Исследование проводили за 2 сут до начала АНОГ, на 3, 7, 15, 18 и 20 сут экспериментального воздействия, а также через 2 сут после окончания АНОГ. Статистический анализ данных проведен с использованием программного обеспечения Statistica 13.0 (IBM; США).</p></sec><sec><title>Результаты</title><p>Результаты. Обнаружено статистически значимое снижение базальной перфузии и амплитуды миогенных колебаний в области кожи лба и голени на 3 сут в условиях антиортостатической гипокинезии. Анализ результатов функциональных проб на предплечье показал уменьшение индекса дыхательной пробы на 10,87% на протяжении всего экспериментального периода, снижение венуло-артериолярной реакции на 3 сут гипокинезии в среднем на 10,64% и увеличение на 91,82% резерва капиллярного кровотока на 3 сут, сохраняющееся на протяжении всего воздействия.</p></sec><sec><title>Выводы</title><p>Выводы. Эффект воздействия АНОГ выражен в снижении кожной перфузии на фоне увеличенного тонуса терминальных артериол и прекапиллярных сфинктеров в области лба и голеней, что может указывать на распределение микрокровотока в сторону более крупных сосудов. Несмотря на стабильность перфузии в области кожи предплечья в покое, проведенные функциональные пробы показали, что, вероятно, условия АНОГ приводят к изменению вазомоторной функции.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Research into the microvasculature as an integral component of the cardiovascular system is particularly relevant in space medicine for identifying adaptive changes to weightlessness and developing new diagnostic criteria for assessing the functional state of an astronaut’s body in long-duration space flights.</p></sec><sec><title>Objective</title><p>Objective. To study the process of microcirculation and its regulation in various skin areas in healthy volunteers under conditions of 21-day head-down (–6°) bed rest (HDBR).</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The experiment involved six male volunteers aged 26–34 years. To simulate translocation of liquid media and physical inactivity, the subjects remained in an antiorthostatic position for 21 days. Microcirculation was studied by laser Doppler flowmetry using LAZMA PF portable laser analyzers (SPE “LAZMA” Ltd, Russia). Participant examination was conducted two days prior the onset of the study, on the 3rd, 7th, 15th, 18th, and 20th day of experimental exposure, as well as two days after the completion of HDBR. Statistical data analysis was performed using the Statistica 13.0 software (IBM, USA).</p></sec><sec><title>Results</title><p>Results. On day 3 of HDBR exposure, a statistically significant decrease in basal perfusion and the amplitude of myogenic oscillations in the skin of the forehead and shin was observed. The analysis of functional tests on the forearm showed a decrease in the respiratory test index by 10.87% throughout the experimental period. On day 3 of hypomobility, a decrease in the venuloarteriolar response by an average of 10.64% and an increase by 91.82% in the capillary blood flow reserve were noted, with the latter persisting throughout the entire exposure.</p></sec><sec><title>Conclusions</title><p>Conclusions. The effect of HDBR is expressed in a decrease in skin perfusion against the background of increased tone of terminal arterioles and precapillary sphincters in the forehead and lower legs, which may indicate microcirculation shift toward larger vessels. Despite the skin perfusion stability in the forearm area at rest, the conducted functional tests showed the probability of changes in vasomotor function under the action of HDBR.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>антиортостатическая гипокинезия</kwd><kwd>кожный кровоток</kwd><kwd>лазерная доплеровская флоуметрия</kwd><kwd>перфузия крови</kwd><kwd>регуляция кожного кровотока</kwd></kwd-group><kwd-group xml:lang="en"><kwd>head-down bed rest</kwd><kwd>cardiovascular system</kwd><kwd>skin blood flow</kwd><kwd>laser Doppler flowmetry</kwd><kwd>blood perfusion</kwd><kwd>skin blood flow regulation</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>работа была выполнена в рамках базовых тематик ИМБП РАН: 64.1, FMFR-2024-0042 и FMFR-2024-0038</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>the work was carried out within the framework of topic FMFR-2024-0042 and FMFR-2024-0038 of the Institute of Biomedical Problems</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">Егоров АД, Ицеховский ОГ.
