Сахарный диабет (СД) ведет к увеличению риска развития гипертензии и сердечно-сосудистых заболеваний, поэтому целью исследования явился анализ сократительной функции предсердий мыши в ответ на аппликацию L-цистеина и H2S. Сократительную активность миокарда в эксперименте in vitro исследовали на изолированных предсердиях мыши. Для моделирования СД использовали аллоксан. Внутрибрюшинная инъекция аллоксана приводила к достоверному повышению концентрации глюкозы в крови, которая при инъекции физиологического раствора достоверно не увеличивалась. В контроле добавление NaHS приводило к достоверному дозозависимому снижению амплитуды сокращения миокарда, тогда как в условиях моделирования СД отрицательный инотропный эффект NаHS был достоверно ниже, чем в контрольных условиях. В контроле L-цистеин достоверно уменьшал амплитуду сокращения, тогда как в условиях моделирования СД L-цистеин в тех же концентрациях не приводил к достоверным изменениям амплитуды сокращения. Полученные данные свидетельствуют о том, что чувствительность предсердия мыши к H2S и субстрату его синтеза L-цистеину заметно снижается в условиях моделирования СД.</p></abstract><trans-abstract xml:lang="en"/><kwd-group xml:lang="ru"><kwd>предсердия мыши</kwd><kwd>L-цистеин</kwd><kwd>сахарный диабет</kwd><kwd>аллоксан</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hydrogen sulfide</kwd><kwd>mouse atrium</kwd><kwd>L-cysteine</kwd><kwd>diabetes</kwd><kwd>alloxan</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">Ситдикова Г.Ф., Зефиров А.Л.
