Выявить структурные изменения аорты в восстановительном периоде после длительной геморрагической гипотензии и последующей реинфузии крови.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Проведено две серии экспериментов (контрольная и опытная) по 10 белых беспородных крыссамцов в каждой. Животных наркотизировали тиопенталом натрия (25 мг/кг). 60минутную геморрагическую гипотензию (40 мм рт. ст.) вызывали катетеризацией левой общей сонной артерии, после чего проводили реинфузию крови и ушивали рану. Время наблюдения за животными составило 60 суток, по истечению которых для исследования забирали фрагменты грудного и брюшного отдела аорты. Гистологические срезы окрашивали гематоксилином и эозином, по Ван Гизону, Вергефу и Вейгерту. Определяли морфометрические и гистометрические параметры, включая процентное соотношение оболочек в стенке сосуда и коэффициенты пропускной способности. </p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что грудной и брюшной отделы аорты отличаются друг от друга морфометрическими параметрами, что определяет различные условия гемодинамики в них при критических состояниях организма. Гипертрофия средней оболочки брюшного отдела аорты за счет утолщения гладкомышечных слоев свидетельствует о ремоделирующих процессах в ее стенке, что после массивной кровопотери сопровождается снижением количества эластических мембран и экспрессией коллагенсодержащих структур. Для грудного отдела аорты подобные изменения выражаются снижением площади средней оболочки, значительным утолщением адвентиции и резким снижением коэффициентов пропускной способности.</p></sec><sec><title>Заключение</title><p>Заключение. Выявленные морфометрические особенности различных отделов аорты следует рассматривать в качестве основы долговременной адаптации, позволяющей максимально эффективно осуществлять кровоснабжение жизненно важных органов в отдаленные сроки восстановительного периода.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to reveal aortic structural changes in the recovery period after longterm hemorrhagic hypotension and further blood reinfusion.</p></sec><sec><title>Material and methods</title><p>Material and methods. Two (control and experimental) series of eexperiments were carried out on 10 out bred albino male rats in each. The animals were anesthetized with sodium thiopental (25 mg/kg). Sixtyminute hemorrhagic hypotension (40 mm Hg) was induced by left common carotid artery catheterization, followed by blood reinfusion and wound closure. The animals were observed for 60 days, thereafter thoracic and abdominal aortic fragments were taken. The histological sections were stained with hematoxylin and eosin by the methods of Van Gieson, Verhoeff, and Veigert. Morphometric and histometric parameters, including the percentage of layers in the vascular wall and transmission capac ity coefficients, were determined.</p></sec><sec><title>Results</title><p>Results. The thoracic and abdominal aortic sections have been found to differ in morphometric parameters, which determined their different hemodynamic conditions in critical conditions. Hypertrophy of the media of the abdominal aorta due to thickening of the smooth muscle layers suggests that there are remodeling processes in its wall, which is accompanied by a smaller number of elastic membranes and by the expression of сollagencontaining structures after massive blood loss. For the thoracic aortic segment, such changes are manifested by a decreased medial area, a considerable advential thickening, and a drastic fall in transmission capacity coefficients.</p></sec><sec><title>Conclusion</title><p>Conclusion. The found morphometric characteristics of different aortic segments should be considered as the basis for longlasting adaptation, which can supply blood to the vital organs as efficiently as possible in late recovery periods.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>геморрагическая гипотензия</kwd><kwd>реинфузия крови</kwd><kwd>структурные изменения аорты.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hemorrhagic hypotension</kwd><kwd>blood reinfusion</kwd><kwd>aortic structural changes</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">Dolgikh V.T., Razgonov F.I., Shikunova L.G.
