The work was carried out on Wistar rats that were divided into 3 groups (6 animals in each): group 1 - intact rats; group 2 - control animals subjected to immobilization stress for 18 h; group 3 - rats treated orally with AE (50 mg/kg) for 7 days and then subjected to immobilization stress. The level of stress-induced brain damage was assessed by a morphometric method, by measuring the proportions of morphologically intact neurons, hyperchromatic shrunken neurons and neurons with the signs of degeneration in layers III-V of the cerebral cortex and CA1 region of the hippocampus in the standard area of the section. Immobilization stress in rats led to a clearly pronounced neuronal damage in the cerebral cortex and hippocampus. AE was found to limit the stress-induced neuronal damage in the cerebral cortex and the hippocampus: the proportion of hyperchromatic shrunken neurons was reduced 3 and 4.6 times, respectively, compared to control.</p></abstract><trans-abstract xml:lang="ru"><p>Целью исследования явились анализ гистологических и морфометрических изменений в головном мозгу у крыс при иммобилизационном стрессе и оценка нейропротективного действия экстракта астрагала перепончатого (Astragalus membranaceus) - ЭА. Работа проведена на крысах линии Вистар, разделенных на 3 группы (по 6 животных в каждой): 1-я группа - интактные крысы; 2-я - контроль - животные, подвергнутые иммобилизационному стрессу в течение 18 ч; 3-я группа - крысы, получавшие перорально ЭА (50 мг/кг) в течение 7 сут и испытавшие иммобилизационный стресс. Степень стрессового повреждения головного мозга оценивали морфометрическим методом, учитывая долю неизмененных, гиперхромных сморщенных нейронов и нейронов с признаками дистрофии в III-V слоях коры большого мозга и области СА1 гиппокампа на стандартной площади среза. Иммобилизационный стресс у крыс приводил к отчетливо выраженному повреждению нейронов в коре большого мозга и гиппокампе. ЭА ограничивал стресс-индуцируемое повреждение нейронов: в коре большого мозга и гиппокампе доля гиперхромных сморщенных нейронов была снижена в 3 и 4,6 раза соответственно по сравнению с контролем.</p></trans-abstract><kwd-group xml:lang="en"><kwd>cerebral cortex</kwd><kwd>hippocampus</kwd><kwd>immobilization stress</kwd><kwd>Astragalus membranaceus extract</kwd><kwd>a neuroprotective effect</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>кора большого мозга</kwd><kwd>гиппокамп</kwd><kwd>иммобилизационный стресс</kwd><kwd>экстракт астрагала перепончатого</kwd><kwd>нейропротективный эффект</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Автандилов Г.
