Функциональное состояние артериолярно-венулярного отделов микрососудистого русла кожи правого предплечья оценивали при помощи лазерной допплеровской флоуметрии с вейвлет-анализом осцилляций кровотока, параметры капиллярного кровотока с использованием метода компьютерной капилляроскопии в ногтевом ложе 4-го пальца правой кисти. Метаболический эффект (улучшение утилизации тканями кислорода и глюкозы) сопровождался достоверным увеличением амплитуды вазомоций в диапазонах эндотелиального ритма на 98 % (p&lt;0,00006), нейрогенного ритма на 50 % (p&lt;0,003) и миогенного ритма на 54 % (p&lt;0,03), увеличением скорости капиллярного кровотока на 90 мкм/с (p&lt;0,02), уменьшением размера перикапиллярной зоны на 15 мкм (p&lt;0,0002), снижением диастолического давления на 4 мм рт. ст. (p&lt;0,03). Полученные результаты демонстрируют тесную взаимосвязь процессов метаболизма и микрогемодинамики и позволяют предположить, что амплитудная активность в диапазоне эндотелиального ритма (0,0095-0,021 Гц) при лазерной допплеровской флоуметрии отражает не только вазомоторную, но и метаболическую функцию эндотелия микрососудов.</p></abstract><trans-abstract xml:lang="en"><p>Correlation between metabolic and microhemodynamic processes in skin was assessed through acute pharmacological test with metabolically active Actovegin in 28 healthy volunteers. Laser Doppler flowmetry in combination with wavelet analysis of blood flow oscillations was used to identify functional state of arteriolar-venular areas of microvascular bed in the right forearm skin; capillary blood flow parameters were assessed through computer capillaroscopy in the nail bed of the right hand 4th finger. The metabolic effect (improved oxygen uptake and glucose disposal by tissues) was accompanied by significant increase vasomotion in endothelial rhythm amplitude by 98 % (p&lt;0.00006), neurogenic rhythm amplitude by 50 % (p&lt;0.003) and myogenic rhythm amplitude by 54 % (p&lt;0.03), with capillary blood flow rate increasing by 90 pm/s (p&lt;0.04), pericapillary zone reducing by 15 pm (p&lt;0.0001) and diastolic blood pressure dropping by 4 mmHg (p&lt;0.02). These results show close correlation between metabolic and microhemodynamic processes, which suggests that the amplitude activity within the range of endothelial rhythm (0.0095-0.021 Hz) during laser Doppler flowmetry does not reflect solely vasomotor but also metabolic function of microvascular endothelium.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кожный кровоток</kwd><kwd>лазерная допплеровская флоуметрия</kwd><kwd>амплитудно-частотный вейвлет-анализ</kwd><kwd>капилляроскопия</kwd><kwd>капиллярный кровоток</kwd><kwd>эндотелий</kwd><kwd>микрогемодинамика и метаболизм</kwd><kwd>вазомоции</kwd><kwd>skin bloodflow</kwd><kwd>laser dopplerflowmetry</kwd><kwd>amplitude-frequency wavelet analysis</kwd><kwd>capillaroscopy</kwd><kwd>capillary blood flow</kwd><kwd>endothelium</kwd><kwd>microhemodynamic and metabolism</kwd><kwd>vasomotion</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Дисфункция эндотелия: причины, механизмы, фармакологическая коррекция / под ред.
