Активное использование редкоземельных элементов, в том числе и тулия (Tm), в различных технологических процессах повышает риски нарушения здоровья, связанные с профессиональной деятельностью работника.</p><p>Цель исследования — изучить особенности иммунного профиля работников предприятия цветной металлургии в условиях контаминации биосред редкоземельными элементами (на примере тулия).</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Обследованы 35 работников предприятия цветной металлургии. Группу сравнения составили работники с уровнем концентрации тулия в крови в границах референтного интервала (n=17), группу наблюдения — работники, в крови которых содержание тулия в 2 раза превышает верхний предел референтных значений (n=18). Методом масс-спектрометрии с индуктивно связанной плазмой изучено содержание тулия в биосредах (кровь). Методом проточной цитометрии выполнена детекция Annexin V-FITC+7AAD+-лимфоцитов (поздний апоптоз/некроз), иммуноферментным — IL6, TNF, IgE общий, аллергосорбентным — специфический IgG к лантаноидам.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что у работников группы наблюдения в 2,3 раза повышено содержание общего IgE и в 2,0 раза экспрессия специфического IgG к лантаноидам по отношению к результатам группы сравнения (р&lt;0,05). Обнаружено, при избыточном содержании тулия в крови отмечается ингибирование клеточной гибели на 15% относительно значений группы сравнения.</p></sec><sec><title>Ограничения исследования</title><p>Ограничения исследования.

The active use of rare earth elements, including thulium (Tm), in various technological processes increases the risks of health problems associated with the professional activities of the employee.</p><p>The purpose of the study is to study the characteristics of the immune profile of workers at a non-ferrous metallurgy enterprise under conditions of contamination of biological media with rare earth elements (using the example of thulium).</p></sec><sec><title>Materials and methods</title><p>Materials and methods. 35 employees of a non-ferrous metallurgy enterprise were examined. The comparison group consisted of workers with the level of thulium concentration in the blood within the reference interval (n=17), the observation group — workers whose blood thulium content was 2 times higher than the upper limit of the reference values (n=18). The content of thulium in biological media (blood) was studied using mass spectrometry with inductively coupled plasma. Flow cytometry was used to detect Annexin V-FITC+7AAD+-lymphocytes (late apoptosis/necrosis), enzyme immunoassay — IL6, TNF, general IgE, allergosorbent — specific IgG to lanthanides.</p></sec><sec><title>Results</title><p>Results. It was found that the workers in the observation group had a 2.3-fold increase in the content of total IgE and a 2.0-fold increase in the expression of specific IgG to lanthanides in relation to the results of the comparison group (p&lt;0.05). It was found that with an excess thulium content in the blood, there is an inhibition of cell death by 15% relative to the values of the comparison group.</p></sec><sec><title>Limitations of the study</title><p>Limitations of the study.
