Материалы и методы. Эксперимент проведен на девяноста белых крысах-самцах зрелого возраста. На протяжении 60 суток крысам ежедневно внутрижелудочно вводили 1 мл физиологического раствора (группа Физ+Деф) или аналогичный объем раствора тартразина в дозе 750 мг/кг изолированно (группа Т750+Деф) или сочетанно с внутримышечным введением селеназы (группа Т750Сел+Деф). На 61-е сутки эксперимента выполняли моделирование перелома большеберцовой кости путем нанесения сквозного дефекта. Гистологическое строение костного регенерата изучали методом световой микроскопии и морфометрии. Определение содержания воды, органических, минеральных веществ в регенерате осуществляли весовым методом, а содержания кальция, магния, цинка в костной золе - методом атомно-абсорбционной спектрометрии. Результаты. В группе Т750+Деф наиболее выраженные изменения относительно данных группы Физ+Деф зарегистрированы на 15-е и 24-е сутки эксперимента: площадь грануляционной ткани регенерата была больше на 118,06% и 84,89%, площадь грубоволокнистой, пластинчатой тканей - меньше на 28,79% и 24,13%, 24,56% и 22,00%. Содержание воды было выше на 4,50% и 12,91%, содержание органических веществ - меньше на 7,00% и 7,49%, кальция - на 6,67% и 5,89%, цинка - на 16,04% и 10,56%. В группе Т750Сел+Деф значения параметров восстанавливались до контрольных быстрее, чем в группе Т750+Деф: установлено увеличение площади грубоволокнистой и пластинчатой тканей на 23,37% и 24,90% на 24-е сутки, содержания кальция, цинка на 7,14%, 10,13% и 5,35%, 10,35% на 15-е и 24-е сутки. Заключение. Шестидесятисуточное воздействие тартразина в дозе 750 мг/кг изменяет гистологическое строение, химический, элементный состав регенерата в разные сроки его формирования, а введение с ним селеназы уменьшает их выраженность.</p></abstract><trans-abstract xml:lang="en"><p>Objective - to study the histological structure, chemical and elemental composition of the tibial regenerate after 60-day exposure to tartrazine at different times of bone healing, as well as to establish the possible effectiveness of sodium selenite. Materials and methods. The experiment was carried out on ninety mature white male rats. For 60 days, rats were daily intragastrically injected with 1 ml of saline solution (Fiz+Def group) or a similar volume of tartrazine solution at a dose of 750 mg/kg in isolation (T750+Def group) or combined with intramuscular administration of selenase (T750Sel+Def group). On the day 61 of the experiment, a tibial fracture was simulated by applying a through defect. The histological structure of bone regenerate was studied by light microscopy and morphometry. The content of water, organic, and mineral substances in the regenerate was determined by the weight method. The content of calcium, magnesium, and zinc in bone ash was determined by atomic absorption spectrometry. Results. In the T750+Def group, the most pronounced changes relative to the Fiz+Def group were recorded on the 15th and 24th days of the experiment. The area of the regenerate granulation tissue was higher by 118,06% and 84,89%, the area of woven bone, lamellar bone was lower by 28,79% and 24,13%. The water content was higher by 4,50% and 12,91%, the organic matter content - by 7,00% and 7,49%, calcium content - by 6,67% and 5,89%, zinc content - by 16,04% and 10,56%. In the T750Sel+Def group, the parameter values rose to the control values faster than in the T750+Def group. An increase in the area of woven and lamellar bones was found by 23,37% and 24,90% on 24th day, the content of calcium and zinc - by 7,14%, 10,13% and 5,35%, 10,35% on 15th and 24th days. Conclusion. Sixty-day exposure to tartrazine at a dose of 750 mg/kg changes the histological structure, chemical, and elemental composition of the regenerate at different times of its formation, and the introduction of selenase with it reduces their severity.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>большеберцовая кость</kwd><kwd>регенерат</kwd><kwd>гистологическое строение</kwd><kwd>химический и элементный состав</kwd><kwd>тартразин</kwd><kwd>селеназа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tibia</kwd><kwd>regenerate</kwd><kwd>histological structure</kwd><kwd>chemical and elemental composition</kwd><kwd>tartrazine</kwd><kwd>selenase</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Токтаров Е.Н., Жанаспаев М.А., Тлемисов А.С., Джунусов Т.Г., Мысаев А.О., Касымов К.Т.
