Эндотелиальные клетки, наряду с другими клетками-мишенями, интенсивно акцептируют эндотоксины с развитием эффектов прямой и цитокин-опосредованной цитотоксичности на сосудистую систему, проявляющихся изменениями тонуса сосудов, реологических свойств крови, системы гемостаза вплоть до развития эндотоксинового шока. Цель. Изучение особенностей реактивности сосудов микроциркуляторного русла кожи при экспериментальной ЛПС-индуцированной эндотоксинемии у самцов и самок крыс. Материал и методы. Моделирование эндотоксинемии проводилось внутрибрюшинным введением ЛПС клеточной стенки бактерии Salmonella enterica самцам и самкам крыс стока Wistar. Использовали две дозы ЛПС: 50 мг/кг и 10 мг/кг. Методом лазерной допплеровской флоуметрии оценивали перфузию кожи до и после ведения ЛПС, изменения кровотока в условиях пробы с локальной контактной гипотермией, вызванной термоэлементом. Результаты. Через 48 часов после введения ЛПС наблюдалось снижение кровотока, особенно выраженное при дозе ЛПС 50 мг/кг. При проведении пробы с локальным охлаждением кожи отмечалось изменение кинетики реакции. Редукция кровотока составила 75 % (ЛПС 50 мг/кг) и 51 % (ЛПС 10 мг/кг), статистически значимо отличаясь от контрольных групп. При этом во всех группах с введением ЛПС отсутствовал классический феномен «холодовой вазодилатации», наблюдаемый у контрольных крыс. Максимальная перфузия после восстановления кровотока у самок достигалась в 3 раза быстрее, чем у самцов (ЛПС 10 мг/кг). Заключение. При экспериментальной ЛПС-индуцированной эндотоксинемии выявлено снижение перфузии кожи, имеющее дозозависимый характер. Получены новые данные об отсутствии выраженной «холодовой вазодилатации» при локальной контактной гипотермии. Результаты исследования свидетельствуют о нарушении механизмов нейрогенной вазоконстрикции и эндотелийзависимой вазодилатации, отражающем системные расстройства регуляции микроциркуляции. При этом у самок прослеживалась более положительная динамика восстановления кровотока в пробе с локальным охлаждением кожи, свидетельствующая о бóльшем функциональном резерве и более эффективном механизме ауторегуляции системы микроциркуляции крови. Функциональная проба с локальным контактным охлаждением кожи высокоинформативна для оценки реактивности сосудов и сохранности механизма ауторегуляции микроциркуляции при моделировании эндогенной интоксикации</p></abstract><trans-abstract xml:lang="en"><p>Bacterial lipopolysaccharide (LPS) plays a leading role in the development of a systemic inflammatory response and endogenous intoxication. However, the sex differences in the functional state of the microcirculatory bed in LPS-induced endotoxinemia have been poorly studied. Objective. To study the characteristics of skin microcirculatory vascular reactivity in experimental LPS-induced endotoxinemia in male and female rats. Material and methods. Modeling of endotoxinemia was performed by intraperitoneal injection of LPS of the cell wall of the bacterium Salmonella enterica to male and female Wistar stock rats. Two doses of LPS were used: 50 mg/kg and 10 mg/kg. We used laser Doppler flowmetry to evaluate skin perfusion before and after LPS injection, blood flow changes under test conditions with local contact hypothermia caused by a thermoelement. Results. 48 hours after LPS injection, a decrease in blood flow was observed, especially pronounced at a dose of LPS 50 mg/kg. During the test with local cooling of the skin, a change in the kinetics of the reaction was noted. Blood flow reduction was 75% (LPS 50 mg/kg) and 51% (LPS 10 mg/kg), statistically significantly different from the control groups. At the same time, the classic phenomenon of “cold vasodilation” observed in control rats was absent in all groups with the injection of LPS. Maximum perfusion after restoration of blood flow in females was achieved 3 times faster than in males (LPS 10 mg/kg). Conclusion. In experimental LPS-induced endotoxinemia, a dose-dependent decrease in skin perfusion was revealed. We obtained new data on the absence of pronounced “cold vasodilation” at local contact hypothermia. The results of the study indicate a violation of the mechanisms of neurogenic vasoconstriction and endothelium-dependent vasodilation, reflecting systemic disorders of microcirculation regulation. At the same time, the females showed a more positive dynamics of blood flow restoration in the test with local cooling of the skin, indicating a greater functional reserve and a more effective mechanism of autoregulation of the blood microcirculation system. A functional test with local contact cooling of the skin is highly informative for assessing vascular reactivity and preservation of the autoregulation mechanism of microcirculation in modeling endogenous intoxication</p></trans-abstract><kwd-group xml:lang="ru"><kwd>крыса</kwd><kwd>локальное охлаждение</kwd><kwd>кожный кровоток</kwd><kwd>микроциркуляция</kwd><kwd>реактивность</kwd><kwd>липополисахарид</kwd><kwd>эндотоксинемия</kwd><kwd>лазерная допплеровская флоуметрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rat</kwd><kwd>local cooling</kwd><kwd>skin blood flow</kwd><kwd>microcirculation</kwd><kwd>reactivity</kwd><kwd>lipopolysaccharide</kwd><kwd>endotoxinemia</kwd><kwd>laser Doppler flowmetry</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">Roved J, Westerdahl H, Hasselquist D.
