В настоящее время в пластической хирургии, контурной пластике и инъекционной косметологии широко используются растительные экстракты и лекарственные средства, действие которых направлено на стимуляцию заживления за счет активации фибриллогенеза и процесса эпителизации. Вместе с тем не учитывается синхронизация этих процессов, которая может быть причиной развития рубцовых осложнений за счет избыточного коллагеногенеза. Авторами статьи предложено в качестве биологически активного компонента, влияющего на все звенья репаративной регенерации, использовать в пластической хирургии и контурной пластике низкомолекулярный хитозан.</p></sec><sec><title>Цель работы</title><p>Цель работы. Провести сравнительную морфологическую оценку влияния гидрофильного геля с низкомолекулярным хитозаном и геля, содержащего композицию экстрактов лекарственных растений, на асептический раневой процесс в острой фазе воспаления (1-е сутки после травмы) и регенераторно-пластические процессы заживления (7-е сутки после травмы).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследования выполнены на 30 мышах-самцах линии ICR. Асептическую рану моделировали под эфирным наркозом, вырезая полнослойный участок кожи с подкожной клетчаткой с площадью не более 50 мм2. Затем на раны животным опытной группы наносили ежедневно гель, содержащий 2% гидроксипропилцеллюлозы (гелеобразующий компонент) и 0,1% низкомолекулярного хитозана (20 кДа), а животным контрольной группы – гель, содержащий композицию экстрактов лекарственных растений. Морфологическую оценку острой фазы раневого процесса у животных опытной и контрольной группы проводили через сутки после моделирования раны, а морфологическую оценку регенераторнопластических процессов у животных опытной и контрольной группы проводили через 7 суток после моделирования раны.</p></sec><sec><title>Результаты</title><p>Результаты. Сравнительные морфологические исследования показали, что гель с низкомолекулярным хитозаном обладает ярко выраженным противовоспалительным действием в острой фазе раневого процесса и превосходит по противовоспалительному действию гель, содержащий композицию экстрактов лекарственных растений. Также было установлено, что гель с низкомолекулярным хитозаном обладает практически равным с гелем, содержащим композицию экстрактов лекарственных растений, эффектом на динамику изменения площади асептической раны. Однако при использовании геля с низкомолекулярным хитозаном наблюдается полноценный процесс репаративной регенерации в кожной ране с участием тканевых макрофагов, отмечается отсутствие нейтрофильной инфильтрации, что свидетельствует о полном купировании воспалительного процесса. Количество фибробластов, коллагеновых и ретикулиновых волокон синхронизировано с активацией процесса заживления ран, и фактически полностью снимается риск развития фиброзных рубцовых осложнений после травмы кожи.</p></sec><sec><title>Заключение</title><p>Заключение. Гель с низкомолекулярным хитозаном может быть весьма перспективным средством для лечения асептических ран в инъекционной косметологии, контурной пластике и пластической хирургии для снятия отека и болевой реакции, купирования острого воспаления и профилактики рубцовых осложнений за счет активации физиологических механизмов репаративной регенерации, обусловленных активацией тканевых макрофагов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Currently, in plastic surgery, contouring and injectable cosmetology, plant extracts and drugs are widely used, the effect of which is aimed at stimulating healing by activating fibrillogenesis and the epithelization process. At the same time, synchronization of these processes is not taken into account, which may cause the development of scar complications due to excessive collagenogenesis. The authors of the article suggest using low-molecular chitosan as a biologically active component affecting all reparative regeneration links in plastic surgery and contour plastic.</p></sec><sec><title>Objective</title><p>Objective. To conduct a comparative morphological assessment of the effect of hydrophilic gel with low molecular weight chitosan and gel containing a composition of extracts of medicinal plants on the aseptic wound process in the acute phase of inflammation (1 day after injury) and regenerative-plastic healing processes (7 days after injury).</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Studies performed on 30 male ICR mice. The aseptic wound was simulated under ether anesthesia by cutting out a full-layer subcutaneous skin area of no more than 50 mm2. A gel containing 2% hydroxypropyl cellulose (gelling agent) and 0.1% low molecular weight chitosan (20 kDa) was then applied daily to the wounds of the test group animals and to the control group gel containing a composition of extracts of medicinal plants animals. Morphological assessment of the acute phase of the wound process in animals of the experimental and control groups was carried out one day after the wound simulation, and morphological assessment of the regenerativeplastic processes in animals of the experimental and control groups was carried out 7 days after the wound simulation.</p></sec><sec><title>Results</title><p>Results. Comparative morphological studies showed that the gel with low molecular weight chitosan has a pronounced anti-inflammatory effect in the acute phase of the wound process and is superior in anti-inflammatory effect to gel containing a composition of extracts of medicinal plants. It was also found that a gel with low molecular weight chitosan has almost the same effect as gel containing a composition of extracts of medicinal plants on the dynamics of the change in the area of the aseptic wound. However, when using a gel with low molecular weight chitosan, a full-fledged process of reparative regeneration in the skin wound with the participation of tissue macrophages is observed, there is no neutrophil infiltration, which indicates a complete relief of the inflammatory process. The number of fibroblasts, collagen and reticulin fibers is synchronized with the activation of the wound healing process and in fact completely removes the risk of developing fibrous scar complications after skin injury.</p></sec><sec><title>Conclusion</title><p>Conclusion. Gel with low molecular weight chitosan can be a very promising agent for the treatment of aseptic wounds, in injectable cosmetology, contouring and plastic surgery to relieve edema, relieve pain, relieve acute inflammation and prevent scar complications by activating physiological mechanisms of reparative regeneration due to the activation of tissue macrophages.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>низкомолекулярный хитозан</kwd><kwd>раневой процесс</kwd><kwd>регенерация кожи</kwd><kwd>пластическая хирургия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>low molecular weight chitosan</kwd><kwd>wound process</kwd><kwd>skin regeneration</kwd><kwd>plastic surgery</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">Schneider C., Klein P., Stolt P., Oberbaum M.
