It was found that after 6 months of modeling of mild and moderate CRF, lamina propria of the oral cavity mucous membranes was diffusely infiltrated with leukocytes. At the same time, relative density of the distribution of the components of blood and lymphatic vascular bed was increased. In severe CRF, the atrophy and hyperkeratosis of the epithelium of the oral cavity mucous membrane developed, while the lamina propria demonstrated sclerosis and significant increase of leukocyte (primarily neutrophil and monocyte) and macrophage numerical density with the formation of small leukocyte infiltrates. In addition, in moderate and severe CRF, the number of eosinophils and plasma cells was increased in the lamina propria which indicates the possible presence of allergic component in the initiation and maintenance of its inflammation.</p></abstract><trans-abstract xml:lang="ru"><p>Методами световой микроскопии изучены морфологические изменения слизистой оболочки полости рта у крыс (n=48) при хронической почечной недостаточности (ХПН) различной степени. Обнаружено, что через 6 мес после моделирования ХПН легкой и средней степени собственная пластинка слизистой оболочки полости рта диффузно инфильтрирована лейкоцитами, возрастает относительная плотность расположения компонентов кровеносного и лимфатического русла. При тяжелой ХПН у крыс происходит атрофия и развивается гиперкератоз эпителия слизистой оболочки ротовой полости, собственная пластинка слизистой оболочки склерозируется, в ней значительно увеличивается численная плотность лейкоцитов (в первую очередь, нейтрофилов, моноцитов), макрофагов, и формируются мелкие лейкоцитарные инфильтраты. Кроме того, при ХПН средней и тяжелой степени в собственной пластинке слизистой оболочки возрастает количество эозинофилов и плазматических клеток, что указывает на возможное присутствие аллергического компонента в инициации и поддержании в ней воспаления.</p></trans-abstract><kwd-group xml:lang="en"><kwd>oral cavity mucosa</kwd><kwd>leukocytic infiltration</kwd><kwd>sclerosis</kwd><kwd>eosinophilia</kwd><kwd>chronic renal failure</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>слизистая оболочка полости рта</kwd><kwd>лейкоцитарная инфильтрация</kwd><kwd>склероз</kwd><kwd>эозинофилия</kwd><kwd>хроническая почечная недостаточность</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ландышев Ю.
