Установлено, что микротубулы и актиновые элементы цитоскелета участвуют в развитии гиперкалиевого и фенилэфрининдуцированного сокращений, а также в расслаблении гладкой мышцы, индуцированном цАМФ. Цитохалазин В более эффективно, чем колхицин, угнетает оба вида сокращений гладкой мышцы аорты. Сократительные реакции при изоосмотической стрикции угнетаются только цитохалазином. Эффективность оперирования цАМФ-опосредованной сигнальной системы зависит от целостности актинового цитоскелета.</p></abstract><trans-abstract xml:lang="en"><p>Influence of cytoskeleton modulation by Colchicine and Cytochalasine B on contractile reactions of smooth muscle segments of rat's aorta caused by physiologically active substances, the membrane's depolarization and cells' striction was investigated by mechanographical method. Microtubules and actinic elements of the cytoskeleton were established to participate in the development of hyper-potassic and phenylephrine -induced contractions as well as in the smooth muscle relaxation induced by cAMP. Cytochalasine B suppresses both kinds of aortic smooth muscle contractions more effectively than Colchicine. Contractile reactions at isoosmotic striction are suppressed only by Cytochalasine. Efficacy of cAMP signal system operating depends on actinic cyto-skeleton integrity.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гладкомышечные клетки</kwd><kwd>цитоскелет</kwd><kwd>цАМФ-опосредованная сигнальная система</kwd></kwd-group><kwd-group xml:lang="en"><kwd>smooth muscle cells</kwd><kwd>cytoskeleton</kwd><kwd>cAMP signal system</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">Баскаков М.Б., Медведев М.А., Ковалев И.В. и др.
