Показано, что гипохлоргидрия приводит к увеличению длительности нерегулярной электрической активности и уменьшению времени покоя, что свидетельствует об усилении некоординированных сокращений тонкой кишки. Уменьшение числа мигрирующих миоэлектрических комплексов и, следовательно, частичное подавление пропульсивной перистальтики способствует избыточному бактериальному росту в проксимальном отделе тонкой кишки.</p></abstract><trans-abstract xml:lang="en"><p>Variations in the basic parameters of the electrical activity of the small intestine in rats were studied using an experimental model of hypochlorhydria caused by an intragastric administration of rabeprazole for 16 days. Hypochlorhydria was found to lead to an increased duration of irregular electric activity and a reduction in the period of quiescence, which indicates an increase in uncoordinated contractions of the small intestine. A decrease in the number of migrating myoelectric complexes and, consequently, a partial suppression of propulsive peristalsis contributes to an excessive bacterial overgrowth in the proximal small intestine.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гипохлоргидрия</kwd><kwd>мигрирующий миоэлектрический комплекс</kwd><kwd>тощая кишка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hypochlorhydria</kwd><kwd>migrating myoelectrical complex</kwd><kwd>jejunum</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Грант ФГБНУ НЦ ПЗСРЧ «Молодёжный проект года».</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ардатская М.Д., Минушкин О.Н., Иконников Н.С.
