Выполнен морфометрический, цитофотометрический и статистический анализ полученных данных. Установлено, что дисплазия соединительной ткани усугубляет течение хронического гастрита, вызывает деструктивные изменения поверхностно-ямочного эпителия, особенно в донном отделе, снижение в них активности сукцинатдегидрогеназы (без существенного изменения активности лактатдегидрогеназы), повышение активности НАДН-дегидрогеназы и кислой фосфатазы, а также угнетение синтеза мукополисахаридов, что приводит к уменьшению их количества не только в эпителиоцитах, но и в поверхностной слизи. Изменения в главных и особенно в париетальных экзокриноцитах менее выражены. Снижение защитного барьера слизистой оболочки при наличии агрессивных ферментов желудочного сока приводит к более частому развитию эрозий, а иногда и язв у детей с хроническим гастритом, развивающимся на фоне дисплазии соединительной ткани.</p></abstract><trans-abstract xml:lang="en"><p>The aim of this study was to investigate the activity of succinate dehydrogenase, lactate dehydrogenase, NADH-dehydrogenase, and acid phosphatase in biopsies of the bottom and pyloric parts of the stomach in children (6-18 years of age) with chronic gastritis and chronic gastritis at the dysplasia of the connective tissue. Histological and histochemical methods, morphometry, cytophotometry and statistical analysis were used.It was found that the connective tissue dysplasia causes destructive changes in simple columnar epithelium, especially in the bottom part, with inhibition of the synthesis of mucopolysaccharides, which leads to a reduction in the number of epithelial cells not only in the simple columnar, but also in the mucus. Changes in the main and, especially, parietal exocrine cells are less pronounced. So, reducing the mucosal barrier in the presence of aggressive factors juice in children with chronic gastritis at the dysplasia of the connective tissue leads to a higher incidence of erosion and sometimes ulcers with increasing disease severity.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>желудок</kwd><kwd>хронический гастрит</kwd><kwd>дисплазия соединительной ткани</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>stomach</kwd><kwd>chronic gastritis</kwd><kwd>connective tissue dysplasia</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">Гастроэнтерология детского возраста / под ред.
