Ischemic brain injury was induced by bilateral common carotid artery occlusion for 7 min. IP protocol comprised 3 cycles of 15 s of reperfusion/15 s of ischemia. After reperfusion for 48 h, the morphometric analysis was conducted, and SDH cytoplasmic activity was assessed using quantitative histochemistry in the pyramidal neurons of the hippocampal areas CA1, СА2, СА3, СА4. The experiment has demonstrated that 7-minute-long ischemia resulted in a significant decrease in the number of viable neurons in CA1 area (up to 24%) and in the СА3 (to 56%) of the hippocampus; besides, it lead to the elevation of SDH activity in the cytoplasm of the neurons in all the hippocampal areas as compared to that in sham-operated animals. The application of IP significantly increased the number of viable neurons in CA1 (up to 52.9%, P&lt;0,01) and in СА3 areas of the hippocampus(up to 88%, P&lt;0,05), and it was accompanied by reduction of SDH activity in surviving neurons in all the hippocampal areas.</p></abstract><trans-abstract xml:lang="ru"><p>Цель настоящей работы — исследование влияния ишемического посткондиционирования (ИПостК) на жизнеспособность различных полей нейронов гиппокампа, а также на активность сукцинатдегидрогеназы (СДГ) в их цитоплазме у 30 песчанок монгольских ( Meriones unguiculatus). Ишемическое повреждение головного мозга моделировали билатеральной окклюзией общих сонных артерий на 7 мин. ИПостК воспроизводили с помощью трех эпизодов реперфузии—ишемии по 15/15 с. Спустя 48 ч реперфузии проводили морфометрический анализ и гистоэнзимологически определяли активность СДГ в цитоплазме пирамидных нейронов полей СА1, СА2, СА3, СА4 гиппокампа. Результаты показали, что 7-минутная ишемия приводит к значимому уменьшению количества неизмененных нейронов в полях СА1 (до 24%) и СА3 (до 56%) гиппокампа, а также во всех полях гиппокампа способствует увеличению активности СДГ в их цитоплазме, по сравнению с показателем у ложнооперированных животных. Применение ИПостК приводит к значимому увеличению количества (до 52,9%, Р&lt;0,01) неизмененных нейронов в поле СА1 и (до 88%, Р&lt;0,05) в поле СА3 гиппокампа и сопровождается понижением активности СДГ в сохранивших жизнеспособность нейронах всех полей гиппокампа.</p></trans-abstract><kwd-group xml:lang="en"><kwd>hippocampus</kwd><kwd>succinate dehydrogenase</kwd><kwd>ischemia-reperfusion</kwd><kwd>ischemic postconditioning</kwd><kwd>Mongolian gerbil</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гиппокамп</kwd><kwd>сукцинатдегидрогеназа</kwd><kwd>ишемия—реперфузия</kwd><kwd>ишемическое посткондиционирование</kwd><kwd>песчанка монгольская</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Журавлева Т.
