В то же время появляются убедительные данные об участии астроцитов в формировании когнитивных функций головного мозга. Нами было проведено исследование на 88-ми крысах Wistar. По результатам тестирования в водном лабиринте Морриса все животные были разделены на две подгруппы: с высоким (ВУК) и низким (НУК) уровнем способностей к пространственному обстановочному обучению в водном лабиринте Морриса. Животным экспериментальной группы (48 животных) проводилось двусторонняя перевязка обеих сонных артерий. Животные выводились из эксперимента на 21, 60 и 90-е сут после операции. Глиальный фибриллярный кислый белок (GFAP), маркер зрелых астроцитов, выявляли с помощью первичных поликлональных кроличьих антител на гистологических срезах прецентральной извилины головного мозга. В ходе исследования были получены данные о более выраженном снижении численной плотности тел астроцитов и количества главных отростков у животных с ВУК в ранние сроки эксперимента — на 21-е сут, а у животных с НУК в более поздние — на 90-е сут. Рост площади, занимаемой отростками астроцитов, у животных с НУК отмечен в ранние сроки — на 60-е сут после моделирования, а у животных с ВУК в более поздние сроки — на 90-е сут после моделирования. Факторный анализ подтвердил наличие двух факторов, ассоциированных с динамикой изучаемых параметров. В заключение делается вывод об альтернативных вариантах изменений в изучаемых группах: преобладании альтерационных изменений в подгруппе с ВУК в ранние сроки, а адаптационных — в более поздние. В подгруппе с НУК, наоборот, альтерационных — в более поздние, а адаптационных — в ранние.</p></abstract><trans-abstract xml:lang="en"><p>The state of cognitive functions in cerebrovascular disorders is one of the most urgent healthcare problems. Recently obtained data convincingly indicate the participation of astrocytes in the formation of cognitive functions of the brain. We conducted a study on 88 Wistar rats. Following the results of testing the rats in a Morris water maze, all animals were divided into two subgroups: those with a high (HLA) and low (LLA) level of spatial situational learning abilities in the Morris water maze test. The animals in the experimental group (48 animals) underwent bilateral ligation of both carotid arteries. The animals were removed from the experiment on the 21st, 60th and 90th day after the operation. Glial ﬁbrillar acidic protein (GFAP), a marker of mature astrocytes, was detected using primary polyclonal rabbit antibodies on histological sections of the precentral gyrus of the brain. Data were obtained on a more pronounced decrease in the numerical density of astrocyte bodies and the number of astrocyte main processes in HLA and LLA animals in earlier (on the 21st day) and later (on the 90th day) stages of the experiment, respectively. The growth of the area occupied by the astrocyte processes occurred earlier in HLA animals (on the 60th day after the simulation) compared to LLA animals (on the 90th day after the simulation). The conducted factor analysis conﬁrmed the presence of two factors associated with the dynamics of the studied parameters. The conclusion is made about alternative variants of changes in the studied groups. The HLA subgroup predominantly demonstrated changes of an alterational character in earlier experimental stages, while adaptive changes were observed in the later stages of the experiment. Conversely, in the LLA subgroup, alterations and adaptations occurred in later and earlier experimental stages, respectively.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>астроциты</kwd><kwd>индивидуальные особенности</kwd><kwd>водный лабиринт</kwd></kwd-group><kwd-group xml:lang="en"><kwd>astrocytes</kwd><kwd>individual features</kwd><kwd>water maze</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">Бонь Е.И., Максимович Н.Е.
