В ходе исследований проводился поиск соединений, перспективных для терапии острого инфаркта миокарда.</p><sec><title>Материалы и методы</title><p>Материалы и методы. Моделирование инфаркта миокарда проводили на крысах линии Вистар массой 250–300 г путем наложения лигатуры на левую коронарную артерию (продолжительность ишемии 45 мин) с последующим ослаблением лигатуры и реперфузией продолжительностью 120 мин. Все манипуляции выполнялись под хлоралозным наркозом с искусственной вентиляцией легких и регистрацией частоты сердечных сокращений, артериального давления и электрокардиограммы. Аскорбат лития вводили в дозе 100 мг/мл перед ишемией внутривенно. Определяли зону риска (ЗР) – зону ишемии/реперфузии, для чего миокард с затянутой лигатурой окрашивали 5%-м перманганатом калия, после чего делали последовательные срезы миокарда и определяли зону инфаркта. Дифференцировку зоны некроза миокарда от ЗР осуществляли путем окрашивания 1%-м раствором 2,3,5-трифенил тетразолия хлорида в течение 30 мин при 37 ºC. Размер зоны инфаркта и зоны риска определяли планиметрическим методом. Концентрацию маркера повреждения миокарда креатинфосфокиназы-МВ (КФК-МВ) в сыворотке крови определяли иммуноферментным методом.</p></sec><sec><title>Результаты</title><p>Результаты. Аскорбат лития статистически значимо уменьшал отношение зоны инфаркта к ЗР на 38% и снижал уровень КФК-МВ в сыворотке крови экспериментальных животных на 42% по сравнению с группой контроля. Аскорбат лития не повлиял на параметры гемодинамики на всех этапах развития коронароокклюзии и реперфузии.</p></sec><sec><title>Заключение</title><p>Заключение.

In the course of the study, we searched for compounds promising for therapy of acute myocardial infarction.</p><sec><title>Materials and methods</title><p>Materials and methods. Myocardial infarction was modeled in Wistar rats by ligating the left coronary artery (the duration of ischemia was 45 minutes) followed by ligature loosening and 120-minute reperfusion. All manipulations were performed under alpha-chloralose anesthesia with mechanical lung ventilation and recording heart rate, blood pressure, and ECG. Lithium ascorbate was administered intravenously at a dose of 100 mg / ml before ischemia. The area at risk (the ischemia / reperfusion zone) was detected by staining the myocardium with tightened ligature with 5% potassium permanganate. After that consecutive myocardial slices were prepared, and infarct size was determined. Differentiation of the infarct size from the area at risk was performed by staining with 1% 2,3,5-triphenyl tetrazolium chloride solution for 30 minutes at 37 ºC. The infarct size and the area at risk were determined by the planimetric method. The serum concentration of myocardial damage marker creatine kinase-MB (CK-MB) was measured using ELISA kits.</p></sec><sec><title>Results</title><p>Results. Lithium ascorbate reduced the infarct size / area at risk ratio by 38% and decreased the serum CPKMB level in the experimental animals by 42% compared to the control group. Lithium ascorbate did not affect hemodynamics parameters during coronary artery occlusion and reperfusion.</p></sec><sec><title>Conclusion</title><p>Conclusion. The cardioprotective effect of lithium ascorbate in cardiac ischemia / reperfusion in vivo was found.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>инфаркт миокарда</kwd><kwd>соли лития</kwd><kwd>ишемия</kwd><kwd>реперфузия</kwd><kwd>аритмии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>myocardial infarction</kwd><kwd>lithium salts</kwd><kwd>ischemia</kwd><kwd>reperfusion</kwd><kwd>arrhythmias</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке программы «Приоритет 2030».</funding-statement><funding-statement xml:lang="en">The study was funded by the Priority 2030 program.</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">Mensah G., Fuster V., Murray C., Roth A.G.
