It was found that rats treated by rotenone were characterized by reduced motor activity and displayed characteristics of experimental parkinsonism. These changes were accompanied by a decreased tyrosine hydroxylase staining in the processes of the s. nigra dopamine neurons and aggregation of α-synuclein in their bodies, as well as by significant loss of dopamine cells in the rostral part of the s.nigra. Rotenone produced bilateral local destruction of brain tissue with surrounding activated astrocytes in the dorsal parts of the striatum bilaterally. One may conclude that a parkinsonian model induced by rotenone is characterized by degenerative changes of dopamine neurons in the s. nigra, with α-synuclein aggregation and local and symmetrical injury of the striatum (with the involvement of dopaminergic fibers, neurons, neuroglia and cerebral vessels), which presumably reflects rotenone-induced mitochondrial dysfunction.</p>  <p> </p> <p> </p></abstract><trans-abstract xml:lang="ru"><p>Для исследования одного из наиболее распространенных заболеваний нервной системы – паркинсонизма – у крыс Вистар моделировали данное состояние путем длительного введения пестицида ротенона, после чего методами иммуноморфологии и компьютерной морфометрии изучали изменения нейронов и нейроглии в нигростриатных образованиях мозга. Обнаружили, что под влиянием ротенона у животных снижалась двига-тельная активность и появлялись симптомы экспериментального паркинсонизма, что сопровождалось уменьшением в черной субстанции интенсивности окрашивания на тирозингидроксилазу в отростках нейронов и накоплением α-синуклеина в телах нейронов, а также значимым уменьшением числа дофаминовых нейронов в ростральном отделе черной субстанции. В дорсальном отделе стриатума обоих полушарий мозга ротенон вызывал очаги деструкции, окруженные валом активированных астроцитов. Таким образом, модель паркинсонизма, индуцированного ротеноном, характеризуется дегенеративными изменениями дофаминовых нейронов черной субстанции с отложением в них агрегатов α-синуклеина, локальной и симметричной деструкцией структур стриатума с вовлечением в процесс дофаминергических волокон, нейронов, нейроглии и церебральных сосудов, что, вероятно, является следствием нарушения митохондриального дыхания, вызываемого ротеноном.</p></trans-abstract><kwd-group xml:lang="en"><kwd>parkinsonism</kwd><kwd>brain</kwd><kwd>striatum</kwd><kwd>substantia nigra</kwd><kwd>mitochondrial toxins</kwd><kwd>immunohistochemistry</kwd><kwd>tyrosine hydroxylase</kwd><kwd>glial fibrillary acid protein</kwd><kwd>α-synuclein</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>паркинсонизм</kwd><kwd>головной мозг</kwd><kwd>стриатум</kwd><kwd>черная субстанция</kwd><kwd>митохондриальные токсины</kwd><kwd>иммуногистохимия</kwd><kwd>тирозингидроксилаза</kwd><kwd>глиофибриллярный кислый астроцитарный белок</kwd><kwd>α-синуклеин</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Степанова М.С., Беляев М.С., Стволинский С.Л.
