Effects of treatments were evaluated by magnesium (Mg2+) levels in blood.</p> <p><bold>Methods:</bold> Nonrandomized controlled study was performed. Mg2+ levels were determined in 60 min (groups A and C) and 120 min (groups B and D) after starting the reoxygenation. Groups A and B received no drugs, whereas rats from groups C and D were administered with U-74389G.</p> <p><bold>Results:</bold> 40 rats 16–18 weeks old of a mean weight of 2312 g were employed in the study. It is demonstrated that U-74389G administration did not alter the Mg2+ levels (decrease in Mg2+ concentration was 0.28±2.75%; p =0.917). Reoxygenation non-significantly increased the Mg2+ levels by 4.27±2.66% (p =0.107). Together, the U-74389G administration and reoxygenation non-significantly increased the Mg2+ levels by 0.36±1.64% (p =0.823).</p> <p><bold>Conclusion:</bold> U-74389G administration, alone or in concert with reoxygenation did not significantly affect Mg2+ level in blood after experimental hypoxia in rats.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования:</bold> изучить влияние антиоксидантного лекарственного средства U-74389G на содержание магния (Mg2+) в сыворотке крови на примере крысиной модели гипоксии–реоксигенации, используя ранее установленный протокол.</p> <p><bold>Методы:</bold> проведено сравнительное нерандомизированное исследование. Эффективность лечения оценивали на основании данных о содержании Mg2+ в сыворотке крови. Концентрацию Mg2+ измеряли после эпизодов реоксигенации длительностью 60 (группы А и С) и 120 мин (группы B и D). Согласно протоколу, группам С и D вводили U-74389G, группам A и B не назначали никаких препаратов.</p> <p><bold>Результаты:</bold> в исследовании использовали 40 крыс в возрасте 16–18 нед со средней массой тела 231,875 г. Назначение U-74389G существенно не повлияло на концентрацию Mg2+ (отмечено снижение его содержания на 0,28±2,75%; p =0,917). Увеличение длительности эпизода реоксигенации несущественно повышало уровень Mg2+ (на 4,27±2,66%; p =0,107). Одновременное введение U-74389G и увеличение длительности эпизода реоксигенации незначительно увеличивали концентрацию Mg2+ (на 0,36±1,64%; p =0,823).</p> <p><bold>Заключение:</bold> применение препарата U-74389G или единовременное его назначение вместе с процессом реоксигенации не оказывают существенного влияния на содержание Mg2+ в крови у крыс после экспериментальной гипоксии.</p></trans-abstract><kwd-group xml:lang="en"><kwd>hypoxia</kwd><kwd>reoxygenation</kwd><kwd>U-74389G</kwd><kwd>magnesium</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гипоксия</kwd><kwd>реоксигенация</kwd><kwd>U-74389G</kwd><kwd>магний</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Экспериментальныц научно-исследовательский центра«ELPEN Фармацевтика» (ЕРЦЭ; Афины, Греция)</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
