The experiments performed have shown that the exposure to hypoxia on postnatal day 2 resulted in a significant damage to the hippocampal field structure. Differential field sensitivity to the damaging factor was also detected. At postnatal day 20, the cell death was found in all the fields and the thinning of pyramidal neuron layers was observed. The neuronal death was mostly expressed in СА4 and СА3 fields. At postnatal day 30, the neuronal death remained significant in СА4 field, while it was reduced in СА3 field and was not found in СА1 field, however, in fascia dentata the death of neurons of the granular layers was increased. Along with it, the dimensions of the pyramidal neuron cell bodies were reduced in all the hippocampal fields. Also, in all the hippocampal fields, the activation of astrocytic reaction was found, which was more expressed in СА4 field, where gliosis was found to remain until prepuberal age (day 30).</p></abstract><trans-abstract xml:lang="ru"><p>Целью работы было изучение отдаленных последствий воздействия острой нормобарической гипоксии в перинатальный период в становлении гиппокампальной формации у крыс. Проведенное исследование показало, что воздействие гипоксии на 2-е сутки постнатального развития приводит к значительному повреждению структуры полей гиппокампа, при этом обнаружена разная их чувствительность к повреждающему фактору. На 20-е сутки во всех полях наблюдается гибель клеток и истончение слоев пирамидных нейронов. Наиболее выраженная гибель нейронов имеет место в полях СА4 и СА3. На 30-е сутки в поле СА4 сохраняется значительная гибель нейронов, она снижается в поле СА3 и не обнаруживается в поле СА1, однако в fascia dentata гибель нейронов зернистого слоя увеличивается. Наряду с этим, уменьшаются размеры тел пирамидных нейронов во всех полях гиппокампа. Также во всех полях гиппокампа обнаруживается активация астроцитарной реакции, она более выражена в поле СА4, где глиоз сохраняется до препубертатного возраста (30 сут).</p></trans-abstract><kwd-group xml:lang="en"><kwd>hippocampus perinatal hypoxia</kwd><kwd>cell death</kwd><kwd>neuronal dimensions</kwd><kwd>astrocytic reaction</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гиппокамп</kwd><kwd>перинатальная гипоксия</kwd><kwd>гибель клеток</kwd><kwd>размер нейронов</kwd><kwd>реакция астроцитов</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Коржевский Д.Э., Григорьев И.П. и Отеллин В.А.
