To date, burn injury remains a complex type of damage to skin tissues. Along with local destructive and dystrophic phenomena, systemic changes in the body are observed. The aim of the study was the experimental study of the immune reactivity of the body of nonlinear rats under conditions of “burn” stress formed as a result of contact thermal trauma. Materials and Methods. The study was carried out on non-linear male rats with an average mass of 220 gr. The functional activity of the immune system of laboratory animals was evaluated on the basis of standard tests assessing the adaptability of the immune system. Results and Discussion. In an experimental study, it was found that in the dynamics of burn injury in laboratory animals, variable changes in the body’s immune reactivity were observed at the level of the cellular and humoral links of immunity, which was manifested by a decrease in the WGST index and an increase in the following indicators - antibody titer, phagocytic index (FI), phagocytic number (FF), leukocytic coefficient and number of leukocytes. The increased content of stick-n uclear forms indicated the activation of granulocytopoiesis, which determined the deregenerative nuclear shift of neutrophil granulocytes to the left. Along with these changes, a decrease in the mass of immune organs (thymus and spleen) was observed, which can be explained by the expression of accidental involution caused by intoxication against the background of a thermal burn. Conclusion. Under conditions of “burn” stress, an immune imbalance occurs in the form of activation of some and suppression of other links at different observation times. Thus, during the burn process, systemic immune changes taking place at the body level have a multi-d irectional dynamic character, which indicates the adaptive capabilities of the immune system.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Актуальность. На сегодняшний день сложным видом повреждения тканей кожи остается ожоговая травма. Наряду с локальными деструктивными и дистрофическими явлениями наблюдаются системные изменения в организме. Цель исследования - экспериментальное изучение иммунной реактивности организма нелинейных крыс в условиях «ожогового» стресса, сформированного в результате контактной термической травмы. Материалы и методы. Исследование проводили на нелинейных крысах-с амцах средней массы 220 гр. Функциональную активность иммунной системы лабораторных животных оценивали на основании стандартных тестов оценки адаптивности иммунной системы. Результаты и обсуждение . В ходе экспериментального исследования установлено, что в динамике ожоговой травмы у лабораторных животных наблюдались вариабельные изменения иммунной реактивности организма на уровне клеточного и гуморального звеньев иммунитета, что проявлялось снижением индекса РГЗТ и увеличением следующих показателей - титра антител, фагоцитарного индекса, фагоцитарного числа, лейкоцитарного коэффициента и количества лейкоцитов. Повышенное содержание палочкоядерных форм указывало на активацию гранулоцитопоэза, что определяло дерегенеративный ядерный сдвиг нейтрофильных гранулоцитов влево. Наряду с указанными изменениями наблюдали снижение массы иммунных органов (тимуса и селезенки), что можно объяснить выражением акцидентальной инволюции, вызываемой интоксикацией на фоне термического ожога. Выводы. В условиях «ожогового» стресса происходит иммунный дисбаланс в виде активации одних и супрессии других звеньев в разные сроки наблюдений. Таким образом, в ходе ожогового процесса происходящие на уровне организма системные иммунные изменения имеют разнонаправленный динамический характер, что свидетельствует об адаптивных возможностях иммунной системы.</p></trans-abstract><kwd-group xml:lang="en"><kwd>thermal injury</kwd><kwd>“burn” stress</kwd><kwd>cellular and humoral immune units</kwd><kwd>immune imbalance</kwd><kwd>activation</kwd><kwd>suppression</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>термическая травма</kwd><kwd>«ожоговый» стресс</kwd><kwd>клеточное и гуморальное звенья иммунитета</kwd><kwd>иммунный дисбаланс</kwd><kwd>активация</kwd><kwd>супрессия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Makhneva NV.
