Аминокислоты и их дериваты принимают участие в синаптической передаче как нейротрансмиттеры и нейромодуляторы, а некоторые из них участвуют в образовании медиаторов нервной системы. Поэтому изучение состояния аминокислотного пула при неполной ишемии головного мозга играет значимую роль.</p><p>Цель – оценить характер изменения пула аминокислот и оценить их участие в оксидативных процессах у крыс с неполной ИГМ.</p></sec><sec><title>Методы и материалы</title><p>Методы и материалы. Опыты выполнялись на 16 самцах беспородных белых крыс массой 260±20 г с соблюдением требований Директивы Европейского Парламента и Совета № 2010/63/EU от 22.09.2010 г. о защите животных, использующихся для научных целей.</p></sec><sec><title>Результаты</title><p>Результаты. По сравнению с показателями в группе «контроль» у крыс с продолжительностью ишемического периода 1 час в теменной доле происходило уменьшение содержания серосодержащих аминокислот: метионина на 12 % и цистеата на 28 %. Наряду с этим отмечалось увеличение L-аргинина в теменной доле на 39 %, а в гиппокампе – на 56 %.</p></sec><sec><title>Выводы</title><p>Выводы. Для одночасовой неполной ишемии головного мозга характерны следующие изменения: уменьшение содержания серосодержащих аминокислот со снижением метионина и повышение содержания L-аргинина. Изменения в теменной доле и гиппокампе носили аналогичный характер, за исключением отсутствия падения уровня цистеата в гиппокампе, как отражение более высокой чувствительности теменной доли к дефициту кислорода по сравнению с гиппокампом.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Amino acids and their derivatives are involved in synaptic transmission as neurotransmitters and neuromodulators, and some of them are involved in the formation of neurotransmitters of the nervous system. Therefore, the study of the state of the amino acid pool in incomplete cerebral ischemia plays a significant role.</p><p>The objective was to assess the nature of changes in amino acid pool and evaluate their participation in oxidative processes in rats with incomplete cerebral ischemia.</p></sec><sec><title>Methods and materials</title><p>Methods and materials. The experiments were carried out on 16 male outbred white rats weighing 260±20 g in compliance with the requirements of the Directive of the European Parliament and of the Council No. 2010/63/EU of September 22, 2010 on the protection of animals used for scientific purposes.</p></sec><sec><title>Results</title><p>Results. Compared with the indicators in the control group, rats with an ischemic period of 1 hour in the parietal lobe had a decrease in the content of sulfur-containing amino acids: methionine by 12 % and cysteate by 28 %. In addition, there was an increase of L-arginine in the parietal lobe by 39 %, and in the hippocampus – by 56 %.</p></sec><sec><title>Conclusions</title><p>Conclusions. The following changes are characteristic for one-hour incomplete cerebral ischemia: a decrease in the content of sulfur-containing amino acids, with a decrease in both methionine and an increase in the content of L-arginine. Changes in the parietal lobe and hippocampus had a similar nature, except for the absence of a drop in the level of cysteate in the hippocampus, as a reflection of the higher sensitivity of the parietal lobe to oxygen deficiency, compared with the hippocampus.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>аминокислоты</kwd><kwd>нейроны</kwd><kwd>ишемия</kwd><kwd>гиппокамп</kwd></kwd-group><kwd-group xml:lang="en"><kwd>amino acid</kwd><kwd>neurons</kwd><kwd>ischemia</kwd><kwd>hippocampus</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">Разводовский Ю.
