В ходе исследования «случай-контроль» у детей в условиях аэрогенной экспозиции бенз(а)пиреном установлены признаки угнетения фагоцитарной активности лейкоцитов и формирования специфической гаптенной гиперсенсибилизации (IgG к бенз(а)пирену), сопряжённые с контаминацией крови бенз(а)пиреном. Выявленные изменения иммунного профиля и ксенобиального состава биосред у детей в условиях аэрогенной экспозиции бенз(а)пиреном в дозе 0,00761 мкг/(кг*день) на субарктической урбанизированной территории являются сопоставимыми со значениями данных показателей у детей, проживающих в условиях внешнесредового воздействия бенз(а)пирена в дозе 0,08689 мкг/(кг*день) на урбанизированной территории в умеренном климатическом поясе (p&gt;0,05). Результаты экспериментального исследования иммунотропных эффектов пероральной экспозиции бенз(а)пиреном в среднесуточной дозе 0,175 мкг/кг*день и воздействия холодового фактора in vivo также демонстрируют признаки угнетения фагоцитоза у мышей. При этом минимальные значения показателей процента фагоцитоза, фагоцитарного числа и фагоцитарного индекса наблюдаются при сочетанном воздействии бенз(а)пирена и холодового фактора, что подтверждает гипотезу модификации иммунотоксического действия бенз(а)пирена под воздействием холодового фактора.</p></abstract><trans-abstract xml:lang="en"><p>The comparative assessment of immune profile indicators in children under = benzo(a)pyrene and cold factor influence in a case-control study with the modeling and verification of obtained results in an in vivo experiment was performed. In the course of a case-control study in children under airborne benzo(a)pyrene exposure the signs of phagocytic leukocyte activity inhibition and specific haptenic hypersensitivity formation (IgG to benzo(a)pyrene) associated with blood contamination with benzo(a)pyrene were established. The changes revealed in the immune profile and xenobial biomedia composition in children under airborne benzo(a)pyrene exposure at a dose of 0.00761 mcg/(kg*day) in the subarctic urbanized area, it is comparable to its level in children living under the conditions of external environmental benzo(a)pyrene exposure at a dose of 0.08689 mcg/(kg*day) in an urbanized area in a temperate climate zone (p&gt;0.05). The results of the experimental study of the immunotropic effects of oral benzo(a)pyrene exposure at an average daily dose of 0.175 mcg/kg*day and cold factor influence in vivo also show the signs of phagocytosis inhibition in mice. At the same time, the minimum values of phagocytosis percentage, phagocytic number and phagocytic index are observed with the combined benzo(a)pyrene and cold factor effect which confirms the hypothesis of immunotoxic benzo(a)pyrene exposure effect modification by a cold factor.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бенз(а)пирен</kwd><kwd>холодовой стресс</kwd><kwd>дети</kwd><kwd>иммунный профиль</kwd><kwd>фагоцитоз</kwd><kwd>эксперимент in vivo</kwd></kwd-group><kwd-group xml:lang="en"><kwd>benzo(a)pyrene</kwd><kwd>cold stress</kwd><kwd>children</kwd><kwd>immune profile</kwd><kwd>phagocytosis</kwd><kwd>in vivo experiment</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">Аликина И.
