Local circulatory compensated hypoxia, occurs when dosed dermotension, stimulates proliferation of blood vessels, but to date no proven link between measured growth and the concentration of cytokine HIF-1α.</p> <p>Aim: the aim was to identify patterns between local circulatory compensated hypoxia created by carrying out the dosed dermotension and cytokine concentration of HIF-1α in stretched the flap when closing the wound of the soft tissues.</p> <p>Materials and methods: the experiment was carried out on 18 experimental animals, which was simulated wound scapular area and conducted a hardware apparatus dermotension under the control of laser Doppler flowmetry, formed the skin samples and performed enzyme-linked immunosorbent assay to determine the concentration of cytokine HIF-1α after 30 minutes, 24 hours from the beginning of tissue stretching.</p> <p>Results: the concentration of HIF-1α in the skin before the start of the dermotension was (Me [Q1; Q3]) 110 [98,1; 114,8] ng/ml. A statistically significant increase in the concentration of HIF-1α to 148 [122,2; 221,7] ng/ml (p=0.008) recorded in the group of animals who underwent tissue stretching within 30 minutes, research also showed that the concentration of HIF-1α increased to 330 [246,4; 463,3] ng/ml (p=0.007) after 24 hours from the start of the dosed strains.</p> <p>Conclusion: the concentration of cytokine HIF-1α in stretched the flap increases with dosed dermotension. Thus, the regulation of adaptation of the skin to stretching is performed by increasing the concentration of the cytokine HIF-1α.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность: </bold>метод дозированной дермотензии как один из вариантов пластической реконструкции стопы при дефектах мягких тканей различной этиологии (в том числе и при сахарном диабете) широко применяется в хирургии. Известно, что локальная циркуляторная компенсированная гипоксия, возникающая при дозированной дермотензии, стимулирует процессы пролиферации кровеносных сосудов, однако на сегодняшний день не доказана связь между дозированной дермотензией и изменением концентрации цитокина HIF-1α.</p> <p><bold>Цель: </bold>перед авторским коллективом стояла цель выявить закономерности между локальной циркуляторной компенсированной гипоксией, создаваемой путем проведения дозированной дермотензии и концентрацией цитокина HIF-1α в дистрагируемом лоскуте при закрытии раны мягких тканей.</p> <p><bold>Материалы и методы:</bold> эксперимент проведен на 18 экспериментальных животных, которым моделировали рану лопаточной области и проводили аппаратную дермотензию под контролем лазерной допплеровской флоуметрии, формировали образцы кожи и проводили иммуноферментный анализ с целью определения концентрации цитокина HIF-1α через  30 минут, 24 часа от начала тканевого растяжения.</p> <p><bold>Результаты:</bold> концентрация HIF-1α в коже до начала дермотензии составляла (Ме [Q<sub>1</sub>; Q<sub>3</sub>]) 110 [98,1; 114,8] нг/мл. В группе животных, которым выполняли тканевое растяжение в течение 30 минут зафиксировано статистически значимое увеличение концентрации HIF-1α до 148 [122,2; 221,7] нг/мл (р=0,008), через 24 часа от начала дозированного растяжения, выявлено, что концентрация HIF-1α увеличилась до 330 [246,4; 463,3] нг/мл (р=0,007).</p> <p><bold>Вывод: </bold>при дозированной дермотензии увеличивается концентрация цитокина HIF-1α в дистрагируемом лоскуте. Таким образом, регуляция адаптации кожных покровов к растяжению осуществляется за счет увеличения концентрации цитокина HIF-1α.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Keywords: dosed dermotension, tissue hypoxia, hypoxia inducible factor, HIF-1α, enzyme immunoassay.</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Ключевые слова: дозированная дермотензия, тканевая гипоксия, гипоксией индуцибельный фактор, HIF-1α, иммуноферментный анализ.</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">References</mixed-citation><mixed-citation xml:lang="ru">Список литература</mixed-citation></citation-alternatives></ref><ref id="B2"><label>2.</label><citation-alternatives><mixed-citation xml:lang="en">Mitish, V.A.
