Изучение клеточных кластеров в условиях воздействия экзогенных гаптенов in vivo с использованием в качестве модельного объекта белых нелинейных мышей позволяет расширить наши знания о механизмах и особенностях иммунотропных эффектов бенз(а)пирена, что определяет актуальность данного исследования. В эксперименте участвовали 12 самок беспородных (нелинейных) белых мышей. Концентрация бенз(а)пирена при однократном поступлении составила 6 мкг/л, в качестве нейтрализатора его эффектов и адаптогена использован концентрат Chlorella growth factor (CGF), последовательно поступавший в течение 4 недель в количестве 60-70 млн/мл живых клеток, оба вещества вводились через пероральный зонд в объеме 1 мл. Исследование фагоцитарной активности клеток проводили по методике Каплина В.Н. Анализ общего количества лейкоцитов и лимфоцитов проводили с использованием унифицируемых общеклинических методов анализа на гематологическом анализаторе. Изучение кластеров клеточной дифференцировки проводилось методом проточной цитометрии (CD25, CD95, CD11а, CD309). Для статистической обработки результатов исследования применяли методы математической статистики с помощью программы Microsoft® Office Excel, Statistica 6.0. Установлено, что субхроническая (подострая) интоксикация бенз(а)пиреном в условиях эксперимента in vivo приводила к значимой модификации клеточного иммунитета по сравнению с контролем, фенотипом которой выступали дефицит факторов врожденного клеточного иммунитета (система гранулоцитарного фагоцитоза) и дисбаланс адаптивного клеточного иммунитета с преимущественным угнетением апоптотической активности (CD95+) и моделированием интегрин- и VEGF-опосредованных сценариев (CD11a, CD309). Причем последовательное поступление природного модификатора Chlorella growth factor характеризовалось нормализацией фагоцитарной активности и отменой индуцированных бенз(а)пиреном эффектов. Ограничения исследования, полученных результатов и выводов обусловлены малым (ограниченным) объемом выборки. В результате изучения in vivo особенностей фагоцитоза и кластеров клеточной дифференцировки иммуноцитов мышей, в условиях последовательной экспериментальной субхронической экспозиции техногенных и природных модификаторов, выявлен дисбаланс показателей неспецифического и адаптивного клеточного иммунитета, сопряженный с формируемыми бенз(а)пиреном гранулоцитарной альтерацией и нарушением контроллинга клеточной пролиферации, отменяемые CGF. Последовательное поступление комплекса CGF приводило к оптимизации работы иммунной системы по ряду его показателей, позитивной модификации иммунотропных эффектов бенз(а)пирена, снимая супрессию гранулоцитарного и сопряженного с интегрином лимфоцитарного ростков крови, оказывая преимущественно фагоцитоз-протективные эффекты, а также антиапоптотическое и интегрин-миметическое действие.</p></abstract><trans-abstract xml:lang="en"><p>Benz(a)pyrene is a first hazard class aromatic compound which exerts carcinogenic, mutagenic, hematotoxic, and immunotropic effects. The study of cell clusters influenced in vivo by exogenous haptens using laboratory mice as a model object allows us to expand knowledge about the mechanisms and features of immunotropic effects induced by benzo(a)pyrene. The experimental series involved 12 female outbred white mice. The concentration of benzo(a)pyrene for a single dose was 6 μg/L, To neutralize its effects, the Chlorella growth factor (CGF) concentrate was used as an adaptogen, which was consistently administered over 4 weeks at a dose of 60-70 mlns/mL of living cells. Both substances were administered via oral tube in a volume of 1 mL. The study of cell phagocytosis was carried out by the method of V.N. Kaplin. Analysis of the total number of leukocytes and lymphocytes was carried out using a hematology analyzer. The study of cell differentiation clusters was carried out using flow cytometry. Microsoft® Office Excel and Statistica 6.0 programs were used for statistical evaluation. Results: subchronic intoxication with benzo(a) pyrene under the in vivo experimental conditions led to significant modification of cellular immunity, exhibiting a phenotype of deficient innate cellular immunity factors, and imbalance of adaptive cellular immunity with a predominant inhibition of apoptotic activity (CD95+) and modeling of integrin- and VEGFmediated events (CD11a, CD309). Sequential intake of the natural modifier (CGF) was characterized by normalization of phagocytic activity and alleviation of benzo(a)pyrene-induced effects. Conclusions of the study are limited by small number of experimental sample, The in vivo experiment have shown an imbalanced pattern of nonspecific and adaptive cellular immunity, associated with granulocyte changes caused by benzo(a)pyrene along with disturbed control of cell proliferation alleviated by CGF. The intake of the CGF complex led to optimization of immune system as shown by a number of indexes, along with positively modified immunotropic effects of benzo(a)pyrene with cancelled suppression of granulocytic and integrin-associated lymphoid lineages, which provides, mostly, phagocytosis protection, as well as antiapoptotic and integrin-mimetic effects.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бенз(а)пирен</kwd><kwd>токсичность</kwd><kwd>фактор роста хлореллы</kwd><kwd>эксперимент in vivo</kwd><kwd>фагоцитоз</kwd><kwd>иммунорегуляция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>benzo(a)pyrene</kwd><kwd>toxicity</kwd><kwd>Chlorella growth factor</kwd><kwd>in vivo experiment</kwd><kwd>phagocytosis</kwd><kwd>immunoregulation</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">Гребенкина А.С., Свидерский Н.Г.
