Capsaicin was administered to adult animals 3 times with an interval of 24 hrs, in a total dose of 125 mg/kg, the material was taken on the 14th day. The administration of capsaicin caused a decrease in the proportion of CABimmunopositive (CAB-IP) neurons in SGSN (by 60%) and in dorsal horn laminas I-II-III (by 8, 18 and 15%, respectively), while the average size of CAB-IP neurons increased due to intracellular edema. As a result of deafferentation, similar morphometric and structural changes of CAB-IP neurons developed in both SGSN and posterior horn of SC gray matter, which were manifested by the central chromatolysis, vacuolation of nucleus and cytoplasm indicative of hydropic dystrophy. The irreversibility of the changes observed in the neurons of SGSN and SC dorsal horn laminas I, II and V was supported by the observations of their nuclear deformation, lysis of nucleolus, reduction of the number of CAB-containing neurons, signs of neuronophagia with the formation of residual nodules in place of the dead cells.</p></abstract><trans-abstract xml:lang="ru"><p>У крыс линии Вистар (n=4) иммуногистохимическим методом исследовали влияние капсаицина на морфометрические и структурные характеристики нейронов заднего рога серого вещества T II-сегмента спинного мозга (СМ) и второго грудного чувствительного узла спинномозгового нерва (ЧУСН), содержащих кальбиндин (КБ) с молекулярной массой 28 килодальтон. Капсаицин вводили взрослым животным 3-кратно с интервалом 24 ч в суммарной дозе 125 мг/кг, материал брали на 14-е сутки. Введение капсаицина вызвало уменьшение доли КБ-иммунопозитивных (КБ-ИП) нейронов в ЧУСН (на 60%) и в пластинах заднего рога I-II-III (на 8, 18 и 15% соответственно), средние размеры КБ-ИП-нейронов увеличились за счет внутриклеточного отека. В результате деафферентации развивались однотипные морфометрические и структурные изменения КБ-ИП-нейронов как в ЧУСН, так и в заднем роге серого вещества СМ, которые проявлялись центральным хроматолизом, вакуолизацией ядра и цитоплазмы, свидетельствуя о гидропической дистрофии. О необратимости выявленных изменений в нейронах ЧУСН и пластинах I, II и V заднего рога СМ свидетельствовали деформация ядра, лизис ядрышка, уменьшение числа КБ-содержащих нейронов, признаки нейронофагии с образованием остаточных узелков на месте погибших клеток.</p></trans-abstract><kwd-group xml:lang="en"><kwd>spinal cord</kwd><kwd>dorsal horn</kwd><kwd>spinal ganglion</kwd><kwd>neurons</kwd><kwd>calbindin</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>спинной мозг</kwd><kwd>задний рог</kwd><kwd>чувствительный узел спинномозгового нерва</kwd><kwd>нейроны</kwd><kwd>кальбиндин</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Маслюков П.
