Methods. Apoptosis of lymphocytes was estimated by method of a flow laser cytofluorimetry. Definition of concentration of cytokins and mediators of apoptosis to blood was carried out by method of the solid-phase enzyme-linked immunosorbent assay. In dabs of blood stain across Romanovsky's - Giemsa studied a limfocytogramma. The maintenance of phenotypes of lymphocytes was determined by method of a double peroxidase tag with use of monoclonal antibodies. Research type retrospective, selections casual, one-stage. Population - inhabitants of the North of the European territory of Russia. Borders of normal distribution of quantitative indices defined by means of Shapiro - Wilk test statistics. Reliability of distinctions between groups was estimated by means of parametrical t-criterion of Student's and Uilkokson's test. The research was conducted with respect for the main standards of biomedical ethics. Results. For realization of a goal two groups of the examined persons have been allocated: with normal (2,5-4,0 х 109 c/l, n = 44) and lowered (&lt;1,5 х 109 c/l, n = 32) the level of lymphocytes in blood. Groups were almost equivalent on age and a sex. Reliability of distinctions between groups was estimated by means of parametrical t-criterion of Student's and Uilkokson's test. It is established that the lack of maintenance of lymphocytes of blood of almost healthy inhabitants of the Arctic is associated with an inhibition of processes of proliferation in system of lymphocytes with decrease in quantity of CD10+ and the IL-2 level. At the examined people concentration of pro-inflammatory cytokins, cytotoxic cells and a transferrin grow. Conclusions. Level of activity of apoptosis of lymphocytes against the background of a limfopenia doesn't change, but prevalence of a mitochondrial way of his initiation is registered that is interconnected with insufficiency of power providing a cell.</p></abstract><trans-abstract xml:lang="ru"><p>Цель - изучить показатели апоптоза (программируемой гибели) лимфоцитов крови при лимфопении у практически здоровых людей в возрасте от 20 до 60 лет, проживающих и работающих в Архангельской области Российской Федерации. Методы. Апоптоз лимфоцитов оценивали методом проточной лазерной цитофлюориметрии. Концентрацию цитокинов и медиаторов апоптоза в крови определяли методом твердофазного иммуноферментного анализа. В мазках крови, окрашенных по Романовскому - Гимзе, изучали лимфоцитограмму. Содержание фенотипов лимфоцитов устанавливали методом двойной пероксидазной метки с использованием моноклональных антител. Тип исследования - ретроспективный, выборки случайные, одномоментные. Генеральная совокупность - жители севера европейской территории России. Границы нормального распределения количественных показателей выявляли при помощи критерия Шапиро - Уилка. Значимость различий между группами оценивали с помощью параметрического t-критерия Стьюдента и критерия Уилкоксона. Исследование проводили с соблюдением основных норм биомедицинской этики. Результаты. Для реализации поставленной цели выделили две группы обследуемых лиц: с нормальным (2,5-4,0 х 109 кл/л, n = 44) и пониженным (&lt;1,5 х 109 кл/л, n = 32) уровнями лимфоцитов в крови. Группы были практически равноценны по возрасту и полу. Установлено, что недостаток содержания лимфоцитов в крови практически здоровых жителей Арктики ассоциирован с ингибицией процессов пролиферации в системе лимфоцитов со снижением количества CD10+ и уровня IL-2. У обследованных людей растут концентрации провоспалительных цитокинов, цитотоксических клеток и трансферрина. Вывод. Уровень активности апоптоза лимфоцитов на фоне лимфопении не меняется, но регистрируется преобладание митохондриального пути его инициации, что взаимосвязано с недостаточностью энергетического обеспечения клетки.</p></trans-abstract><kwd-group xml:lang="en"><kwd>apoptosis of lymphocytes</kwd><kwd>lymphopenia</kwd><kwd>cytokins</kwd><kwd>inhabitants of the Arctic</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>апоптоз лимфоцитов</kwd><kwd>лимфопения</kwd><kwd>цитокины</kwd><kwd>жители Арктики</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Добродеева Л.
