Образцы миокарда забирали во время ранней секции, через 2 часа после констатации биологической смерти у погибших от тяжелого ожогового шока (3 мужчины и 2 женщины), возрастная категория 32-44 года.

Развитие тяжелого ожогового шока сопровождается изменениями ультраструктуры эндотелиоцитов кровеносных микрососудов миокарда левого желудочка, что связано с внутриклеточной деградацией и экзоцитозом. Данные изменения могут свидетельствовать о нарушении везикулярного транспорта в эндотелии кровеносных микрососудов миокарда при ожоговом шоке. Особенностью ультраструктуры эндотелия явилась гетерогенность эндотелиоцитов кровеносных капилляров за счет выявляемых темных и светлых эндотелиальных клеток, различающихся насыщенностью цитоплазмы органеллами. Полученные новые данные могут быть информативными при разработке подходов к интенсивной терапии кардиопротективно-го направления у комбустиологических пациентов с ожоговым шоком.</p></abstract><trans-abstract xml:lang="en"><p>Burn injury is an important medical problem, as it is accompanied by high mortality rates in burn shock.

The development of severe burn shock is accompanied by changes in the ultrastructure of the endothelial cells of the blood microvessels of the left ventricular myocardium, which is associated with intracellular degradation and exocytosis. These ultrastructural changes may indicate impairment of vesicular transport in the endothelium of the myocardial microvessels in burn shock. A feature of the ultrastructure of the endothelium was the heterogeneity of the endothelial cells of the blood capillaries due to the revealed dark and light endothelial cells, which differ in the saturation of the cytoplasm with organelles. The new data obtained on changes in the ultrastructure of the endothelium of the microvasculature of the left ventricular myocardium can be informative in the development of approaches to intensive therapy of cardioprotective direction in combustiological patients with burn shock.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ультраструктура</kwd><kwd>микроциркуляторное русло</kwd><kwd>ожоговый шок</kwd><kwd>миокард</kwd><kwd>эндотелиоциты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ultrastructure</kwd><kwd>microcirculatory bed</kwd><kwd>burn shock</kwd><kwd>myocardium</kwd><kwd>endotheliocyte</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы благодарны Центру коллективного пользования микроскопического анализа биологических объектов ИЦиГ СО РАН (http://www.bionet.nsc.ru/microscopy/) за предоставленное оборудование</funding-statement><funding-statement xml:lang="en">The authors are grateful to the Center for Shared Use of Microscopic Analysis of Biological Objects of Institute of Cytology and Genetics SB RAS (http://www.bionet.nsc.ru/microscopy/) for the equipment provided</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">Pham T.N., Cancio L.C., Gibran N.S., American Bum Association.
