The purpose of this study was to identify the effect of combinations of immunomodulating beta-glucan with immunodepresive preparation cycklophosphamide in organotypic immune tissue of kidney and thymus of 5-months rats.</p> <p><bold>Material and methods.</bold> The method of organotypic cultivation of immune tissues of kidney and thymus was used for rapid screening of the biological activity of the studied beta-glucan.</p> <p><bold>Results.</bold> It has been established that by the combined use of beta-glucan and cycklophosphamide the immunodepresive effect is eliminated.</p> <p><bold>Conclusion. </bold>The data obtained create the basis for beta-glucan usage as a protector by the immunodepresive action of different substances. The base is created for creation of new drugs for treatment of the oncological and infection deseases.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение. </bold>Одной из актуальных проблем в биологии и медицине является идентификация биологически активных молекул, которые влияют на клеточные процессы пролиферации и апоптоза в различных тканях организма.</p> <p><bold>Цель </bold>исследования. Целью настоящего исследования было выявление действия сочетаний иммуномодулирующего бета-глюкана с иммунодепрессивным препаратом циклофосфамидом в органотипической культуре иммунной ткани селезенки и тимуса 5-месячных крыс.</p> <p><bold>Материал и методы. </bold>Метод органотипического культивирования иммунной ткани селезенки крыс использовался для быстрого скрининга биологической активности исследуемых веществ.</p> <p><bold>Результаты. </bold>Установлено, что при совместном применении бета-глюкана с циклофосфамидом устраняется угнетающее действие иммунодепрессантов. Полученные данные создают базу для разработки новых лекарственных средств с использованием бета-глюкана в качестве стимулятора иммунной системы при заболеваниях, связанных с иммуносупрессией, а также при действии цитостатиков, использующихся при лечении онкологических заболеваний.</p></trans-abstract><kwd-group xml:lang="en"><kwd>beta-glucan</kwd><kwd>cycklophosphamide</kwd><kwd>organotypic tissue culture</kwd><kwd>kidney</kwd><kwd>thymus</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>бета-глюканы</kwd><kwd>циклофосфамид</kwd><kwd>органотипическая культура ткани</kwd><kwd>селезенка</kwd><kwd>тимус</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Du B., Meenu M., Liu H., Xu B.
