Histological examination of this model shows fibrin deposition on the surface of the synovial membrane, leukocyte infiltration of the synovial membrane and adjacent tissues, proliferation of the granulation tissue, and emergence of angioid areas, characteristic of RA. The cell response appears as an increase in the plasma cell count and development of follicle-like lymphoid infiltrates; erosion of the articular surface of the cartilage, frequently with deep cartilage destruction over large areas; and epiphysiopathy. The high reproducibility of arthritis induction in this RA model has been demonstrated. The proposed model is promising for the assessment of anti-arthritis preparations and dosage regimens.</p></abstract><trans-abstract xml:lang="ru"><p>Предложена модель ревматоидного артрита, индуцируемого у беспородных морских свинок однократной инъекцией полного адъюванта Фрейнда подкожно в стопу задней конечности. В этой модели гистологически выявляются характерные для ревматоидного артрита в острой фазе отложения фибрина на поверхности синовиальной оболочки, лейкоцитарная инфильтрация синовиальной оболочки и окружающих тканей, разрастания грануляционной ткани и появление участков ангиоматоза. Клеточная реакция выражается увеличением количества плазмоцитов и образованием фолликулоподобных лимфоидных инфильтратов, эрозивным поражением суставной поверхности хряща, нередко с его глубокой деструкцией на больших участках, и поражением эпифизов костей. Показана высокая воспроизводимость индукции артрита в данной модели. Сделано заключение о перспективности использования этой модели для оценки противоартритных препаратов и схем их применения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>rheumatoid arthritis</kwd><kwd>adjuvant-induced arthritis</kwd><kwd>guinea pig</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>адъювант-индуцированный артрит</kwd><kwd>морская свинка</kwd><kwd>ревматоидный артрит</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was financially supported by the Russian Science Foundation (grant No. 14-15-00050).</funding-statement><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Российского научного фонда (грант № 14-15-00050).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>[1] Orlovskaya I.A., Tsyrendorzhiev D.D., Shchelkunov S.N. // Meditsinskaya Immunologiya. 2015, V.17, P.203-210</mixed-citation></ref><ref id="B2"><label>2.</label><mixed-citation>[2] Bolon B., Stolina M., King C., Middleton S., Gasser J., Zack D., Feige U. // J.
