The study was performed on 4 adult female Wistar rats using immunohistochemical and morphometric methods. 14 micrometers-thick cryostat cross- sections of SC were analyzed. Two subpopulations of CAB-immunoreactive (CAB-IR) interneurons were present in the intermediate SM zone in lamina VII in both segments: preganglionic sympathetic neurons and the partition cells. In the ventral horn, also two subpopulations of CAB-IR interneurons were identified: Renshaw cells in the lamina IX in T II and in the lamina VII in L IV; large interneurons in the lamina VIII in and lamina VII in L IV. Segmental differences were observed TIIonly in larger numbers of Renshaw cells and partition cells in L IV. The average cross-sectional area of CAB-IR Renshaw cells and autonomic preganglionic neurons was greater in T II, while this parameter of large ventral horn interneurons and partition cells was greater in L IV.</p></abstract><trans-abstract xml:lang="ru"><p>Целью работы явилось изучение топографии и структуры интернейронов, содержащих кальбиндин (КБ) с молекулярной массой 28 килодальтон, в вентральном роге и промежуточной зоне серого вещества на уровне Т II-и L IV-сегментов спинного мозга (СМ). Исследование выполнено у взрослых крыс-самок линии Вистар (n=4) иммуногистохимическим и морфометрическим методами. Изучены криостатные поперечные срезы СМ толщиной 14 мкм. В промежуточной зоне СМ присутствовали 2 субпопуляции КБ-иммунореактивных (ИР) интернейронов в пластине VII в обоих сегментах: симпатические преганглионарные нейроны и «разделительные клетки» (partition cells). В вентральном роге выявлены также 2 субпопуляции КБ-ИРинтернейронов: клетки Реншоу в пластине IХвТ II и в пластине VII в L IV; крупные интернейроны в пластине VIII вТ II ив пластине VII в L IV. Сегментарные различия заключались лишь в бóльшем количестве клеток Реншоу и разделительных клеток в L IV. Средняя площадь сечения КБ-ИР-клеток Реншоу и автономных преганглионарных нейронов была больше в Т II, а крупных интернейронов вентрального рога и разделительных клеток - в L IV.</p></trans-abstract><kwd-group xml:lang="en"><kwd>spinal cord</kwd><kwd>ventral horn</kwd><kwd>intermediate zone interneurons</kwd><kwd>28 kDa calbindin</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>спинной мозг</kwd><kwd>вентральный рог</kwd><kwd>промежуточная зона</kwd><kwd>интернейроны</kwd><kwd>кальбиндин 28 килодальтон</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Маслюков П.
