The preconditioning methods were applied to experimental rats 24 h before the time when local brain infarct was done by middle cerebral artery occlusion (MCAO). It was found that the ischemic and hypoxic preconditioning resulted in three general morphological changes: 1) the size of infarct zone was reduced by 2.2–3.8 times compared with rats that had not been treated with the preconditioning before MCAO; 2) the preconditioning treatment retained the number of living neurons in penumbra at the level of control rats, while without the preconditioning neuronal count in the penumbra after MCAO was 29% lower; 3) the number of glial cells in penumbra was increased after MCAO by 38% compared with the control level, and continued to increase under the preconditioning treatment up to 60%, that suggests an important role of neuroglia in neuroprotection. Selective blockers of ATP2dependant K+2channels (52hydroxydecanoate and glibenclamide) completely abolished the neuroprotective effects of the preconditioning.</p>  <p> </p> <p> </p></abstract><trans-abstract xml:lang="ru"><p>Прекондиционирование ишемического и гипоксического типов исследовали как способ защиты мозга от острого ишемического поражения. Экспериментальных крыс подвергали прекондиционированию за 24 часа до моделирования у них локального инфаркта мозга, который вызывали путём окклюзии средней мозговой артерии (ОСМА). Обнаружили, что ишемическое и гипоксическое прекондиционирование, приводит к трём главным морфологическим изменениям: 1) размер инфаркта мозга в основной группе животных уменьшается в 2,2–3,8 раза по сравнению с крысами, которых не подвергали прекондиционированию перед созданием ОСМА; 2) прекондиционирование сохраняло число жизнеспособных нейронов в пенумбре на уровне контрольных животных, в то время как без прекондиционирования число нейронов в пенумбре уменьшалось на 29%; 3) число клеток нейроглии в пенумбре после ОСМА увеличивалось на 38% по сравнению с контролем и продолжало увеличиваться под влиянием прекондиционирования (до 60%), что предполагает важную роль нейроглии в нейропротекции. Селективные блокаторы АТР зависимых К+ каналов (5 гидроксидеканоат и глибенкламид) полностью устраняли нейропротектороное действие прекондиционирования.</p></trans-abstract><kwd-group xml:lang="en"><kwd>preconditioning</kwd><kwd>neuroprotection</kwd><kwd>brain infarct</kwd><kwd>ischemic penumbra</kwd><kwd>morphometry</kwd><kwd>magnetic resonance tomography</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>прекондиционирование</kwd><kwd>нейропротекция</kwd><kwd>инфаркт мозга</kwd><kwd>ишемическая пенумбра</kwd><kwd>морфометрия</kwd><kwd>магнитно резонансная томография</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
