The studies were carried out on hybrid pigs at the age of 144 days reared in an industrial pig complex and on Wistar rats aged 5 months with a body weight of 230 - 250 g. For the experiments there was used acaricide insecticide Ivermin (Biovet Drwalew S.A., Poland), which was administered to pigs once subcutaneously in a dose of 0,2 mg / kg and to rats in a tenfold therapeutic dose. Blood samples were taken from pigs either before the administration of Ivermin, and 1, 3, 7, 14 and 30 days after the administration. The level of immunoglobulins (IgG, IgM, IgA) was determined in serum by the method of radial immunodiffusion according to Mancini. To prepare histopreparations, samples of thymus, spleen and lymph nodes were taken from rats 14 days after the administration of the preparation. For statistical processing of experimental data, Student’s T-test for dependent samples has been used.</p><p>When studying pigs’ blood serum, a decrease in the content of IgG was established in all periods of the study. A decrease in level of IgM and IgA was marked in 7 days after the experiment started. At the end of the experiment, the IgG level remained below the background value by 16,4%; IgM - by 15,2%; IgA – by 33%. In the rat thymus, a narrowing of the cortical substance was observed when a toxic dose of Ivermin was injected, with the splenic follicles reduced, and reproduction centers faintly pronounced. Hemosiderin accumulation was detected around the follicles. In the mesenteric lymph nodes, there was found a thickening of the capsule and the expansion of trabeculae. Cortical substance was narrow and paracortical zone was wide. The results of the study indicate a high risk of immunotoxic effect of ivermectin.</p></abstract><trans-abstract xml:lang="ru"><p>Цель работы – выявить иммунотропные эффекты ивермектина у продуктивных и лабораторных животных в реальных и модельных условиях.</p><p>Исследования проведены на свиньях гибридной линии в возрасте 144 дней в условиях промышленного свинокомплекса и крысах линии Вистар в возрасте 5 месяцев с массой тела 230-250 г. В опытах использовали инсектоакарицидный препарат Ивермин (Biovet Drwalew S.A., Польша), который вводили свиньям однократно подкожно в дозе 0,2 мг/кг, крысам – в десятикратной терапевтической дозе. Забор крови у свиней осуществляли до введения Ивермина, через 1, 3, 7, 14 и 30 суток после введения. В сыворотке крови определяли уровень иммуноглобулинов (IgG, IgM, IgA) методом радиальной иммунодиффузии по Манчини. Для приготовления гистопрепаратов брали у крыс кусочки тимуса, селезенки и лимфоузлов через 14 суток после введения препарата. При статистической обработке экспериментальных данных использовали T-критерий Стьюдента для зависимых выборок.</p><p>При исследовании сыворотки крови свиней установлено снижение содержания IgG во все сроки исследования, IgM и IgA – через 7 суток после начала опыта. По окончании эксперимента уровень IgG оставался ниже фонового значения на 16,4%; IgM – на 15,2%; IgA – на 33%. В тимусе крыс отмечено сужение коркового вещества при введении токсической дозы Ивермина, фолликулы селезенки уменьшены, центры размножения в них слабо выражены. Вокруг фолликулов наблюдается скопление гемосидерина. В брыжеечных лимфатических узлах отмечается утолщение капсулы и расширение трабекул. Корковое вещество сужено, паракортикальная зона расширена. Результаты исследования указывают на высокую степень риска иммунотоксических эффектов ивермектина.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Ivermin</kwd><kwd>ivermectin</kwd><kwd>pesticides</kwd><kwd>immunotropic effects</kwd><kwd>rats</kwd><kwd>pigs</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>ивермин</kwd><kwd>ивермектин</kwd><kwd>пестициды</kwd><kwd>иммунотропные эффекты</kwd><kwd>крысы</kwd><kwd>свиньи</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Laing R., Gillan V., Devaney E.
