The deafferentation was modeled by a single subcutaneous administration of 150 mg/kg of capsaicin to 2-day-old rats. Intact rats (n=40) served as a control. To demonstrate NF200 +-neurons the cells were labeled with antibodies against NF200. To count the proportion of immunoreactive neurons, the total neuronal population was marked with NeuroTrace Fluorescent Nissl stain. The results of the work have shown that NF200 +-neurons were found in the ventral horn, intermediate zone and the dorsal horn of the spinal cord and differed from each other in their morphometric characteristics. In capsaicin-treated animals, the numbers of medial and lateral NF200 +-motoneurons and their cross-sectional area were similarly reduced in the spinal cord (plate IX). In the intermediate zone (plate VII) and in the dorsal horn (plates III–IV) the number of NF200 +-neurons in capsaicin-treated animals was not changed but their cross-sectional area exceeded normal values.</p></abstract><trans-abstract xml:lang="ru"><p>Исследование проведено на 80 белых крысах-самках линии Вистар в возрасте 3, 10, 20, 30, 60, 180 и 360 сут с целью изучения влияния деафферентации капсаицином на характер топографии нейронов, содержащих белок нейрофиламентов с массой 200 килодальтон (НФ200 +) в сером веществе II грудного сегмента спинного мозга. Моделирование деафферентации осуществляли путем подкожного однократного введения крысятам на 2-е сутки жизни капсаицина в дозе 150 мг/кг. Контролем служили интактные животные (n=40). Для выявления НФ200 +-нейронов применяли мечение клеток антителами к НФ200. Для расчета доли иммунореактивных нейронов производили мечение всей популяции нейронов красителем Neuro Trace Green Fluorescent Nissl Stain. Результаты работы показали, что НФ200 +-нейроны выявляются в вентральном роге, промежуточной зоне и дорсальном роге спинного мозга и различаются морфометрическими характеристиками. Введение капсаицина привело к одинаковому уменьшению количества и средней площади сечения медиально и латерально расположенных НФ200 +-мотонейронов в спинном мозгу (пластина IХ). В промежуточной зоне (пластина VII) и дорсальном роге (пластины III–IV) изменения количества НФ200 +-нейронов не наблюдалось, но средняя площадь их сечения превышала показатели в норме.</p></trans-abstract><kwd-group xml:lang="en"><kwd>neuron</kwd><kwd>spinal cord</kwd><kwd>200 kD neurofilaments</kwd><kwd>capsaicin</kwd><kwd>ontogenesis</kwd><kwd>rat</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>нейрон</kwd><kwd>спинной мозг</kwd><kwd>нейрофиламенты массой 200 килодальтон</kwd><kwd>капсаицин</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Маслюков П.
