The material of small intestine was taken from 10 male rats in both the zone of ligature application, and proximal and distal zones, 3 cm distant from the ligation zone. The results of the study demonstrate that in partial intestinal obstruction, the nature of structural and functional SMT transformation was variable depending upon differences in functional and destructive loads. During these changes, the remodeling of smooth myocyte population was shown to be one of the mechanisms of SMT adaptation to the changing conditions of functioning. Immunohistochemical analysis found no changes in the pattern of expression of marker and phenotypic proteins in the intestinal zones studied during the dynamics of an experiment.</p></abstract><trans-abstract xml:lang="ru"><p>При использовании световой, электронной микроскопии и иммуногистохимических методов изучали реактивную трансформацию гладкой мышечной ткани (ГМТ) стенки кишки при развитии острой частичной высокой обтурационной кишечной непроходимости. Исследован материал тонкой кишки 10 крыс-самцов, полученный в зоне наложения лигатуры в проксимальной и дистальной зонах, которые отстояли от нее на 3 см. Исследования показали, что при частичной кишечной непроходимости имеет место неодинаковый характер структурно-функциональной трансформации ГМТ, обусловленной различием функциональных и деструктивных нагрузок. При этом перестройка популяции гладких миоцитов является одним из механизмов адаптации ГМТ к изменяющимся условиям функционирования. Иммуногистохимический анализ не выявил изменения характера экспрессии маркерных и фенотипических белков в исследуемых зонах тонкой кишки в динамике эксперимента.</p></trans-abstract><kwd-group xml:lang="en"><kwd>smooth muscle tissue</kwd><kwd>smooth muscle cells</kwd><kwd>reactivity</kwd><kwd>immunohistochemistry</kwd><kwd>electron microscopy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гладкая мышечная ткань</kwd><kwd>гладкие миоциты</kwd><kwd>реактивность</kwd><kwd>иммуногистохимия</kwd><kwd>электронная микроскопия</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Брумберг В.А. и Певзнер Л.З.
