Study of plant extracts that have the ability to neutralize cytotoxic activity of hemolysin. Materials and methods. Preparations of purified and recombinant V. cholerae eltor hemolysin as well as supernatants of V. cholerae strains were used. Determination of cytotoxic activity of hemolysin and neutralizing activity of plant extracts were carried out by using cell cultures СНО-К1 and CaCo2. Results. Out of 9 water extracts only 3 - extracts of Rhei rhizome, Limonium gmeli-nii and Quercus robur neutralized hemolysin in cell culture CHO-K1 and CaCo2, whereas the other extracts - Humulus lupulus, Ocimum basilicum, Chelidonium majus, Juglans regia, Achillea milefolium and Hypericum perforatum did not have anti-cytotoxic effect. Neutralizing properties of extracts are exhibited during their co-incubation with hemolysin preparations and supernatants of V. cholerae strains already within 10 minutes. Conclusion. Plant extracts that have anti-cytotoxic activity against hemolysin are perspective for development of therapeutic-prophylaxis preparations.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Изучение экстрактов растений, обладающих способностью нейтрализовать цитотоксическую активность гемолизина. Материалы и методы. Использованы препараты очищенного и рекомбинантного гемолизина V.cholerae eltor, а также супернатанты штаммов V.cholerae. Определение цитотоксической активности гемолизина и нейтрализующей активности растительных экстрактов проводили с помощью культур клеток СНО-К1 и CaCo2. Результаты. Из 9 водных экстрактов только три - экстракты ревеня, кермека и дуба нейтрализовали гемолизин в культуре клеток СНО-К1 и CaCo2, тогда как остальные экстракты (хмеля, базилика, чистотела, грецкого ореха, тысячелистника и зверобоя) не обладали антицитотоксическим эффектом. Нейтрализующие свойства экстрактов проявляются при их совместном инкубировании с препаратами гемолизинов и супернатантами штаммов V.cholerae уже в течение 10 минут. Заключение. Экстракты растений, обладающие антицитотоксической активностью в отношении гемолизина, перспективны для разработки лечебно-профилактических препаратов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Vibrio cholerae</kwd><kwd>hemolysin</kwd><kwd>plant extracts</kwd><kwd>cell culture</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гемолизин</kwd><kwd>растительные экстракты</kwd><kwd>культура клеток</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Власов В.П., Монахова Е.В., Ушакова И.Е. и др.
