Оригинальные суппозитории с витамином D3 в 3-й группе, и 5-АСК в 4-й группе применяли per rectum. Клинику оценивали по шкале Disease activity index. В очаге повреждения толстой кишки определяли экспрессию MPO и TNFa, содержание нейтрофилов, лимфоцитов, эозинофилов, гистиоцитов, плазмоцитов, фибробластов, язвенный дефект, tissue damage index. Исследование проводили на 2-е, 4-е и 6-е сутки.</p><p>При ЭК на все сутки повышается DAI, в очаге повреждения увеличивается MPO и TNFa, фиксируется язвенный дефект, нейтрофильно-лимфоцитарная инфильтрация, увеличивается TDI. При сравнении морфометрических параметров зоны альтерации при ЭК в условиях применения витамина D3 в отличие от применения 5-АСК выявлено на 2-е сутки снижение количества лимфоцитов, увеличение фибробластов, на 4-е сутки уменьшение количества плазмоцитов и увеличение фибробластов, на 6-е сутки увеличение количества гистиоцитов и фибробластов. Диаметр язвенного дефекта и индекс TDI не имеют значимых различий между сравниваемыми группами. При сравнении эффективности применения витамина D3 в отличие от применения с 5-АСК содержание MPO выше на 6-е сутки, содержание TNFa – на 4-е сутки. </p><p>При ЭК эффекты применения ректальных суппозиториев с витамином D3 на клинические признаки, размер язвенного дефекта, содержание MPO и TNFa в очаге повреждения сопоставимы с эффектами от применения ректальных суппозиториев с 50 мг 5-АСК; более выражены в отношении динамики клеточного состава очага повреждения толстой кишки.</p></abstract><trans-abstract xml:lang="en"><p>The pathogenesis of inflammatory bowel diseases has not been fully studied, and the therapies used have side effects that limit their use.</p><p>The purpose of this study is to conduct a clinical and immunological analysis of the effectiveness of vitamin D3 in the original rectal suppositories in experimental colitis (EC).</p><p>EC was modeled with oxazolone. Original suppositories with vitamin D3 in group 3 and 5-ASA in group 4 were used per rectum. The clinic was evaluated on the Disease activity index scale. The expression of MPO and TNFa, the content of neutrophils, lymphocytes, eosinophils, histiocytes, plasmocytes, fibroblasts, ulcerative defect, tissue damage index were determined in the focus of colon injury. The study was carried out on days 2, 4 and 6.</p><p>With EC, DAI increases for the entire day, MPO and TNFa increase in the lesion, ulcerative defect is</p><p>fixed, neutrophil-lymphocytic infiltration increases, and TDI increases. When comparing the morphometric parameters of the alteration zone in EC under the conditions of vitamin D3 use, in contrast to the use of 5-ASA, a decrease in the number of lymphocytes, an increase in fibroblasts was revealed on day 2, a decrease in the number of plasmocytes and an increase in fibroblasts on day 4, an increase in the number of histiocytes and fibroblasts on day 6. The diameter of the ulcerative defect and the TDI index have no significant differences between the compared groups. When comparing the effectiveness of vitamin D3, in contrast to the use of 5-ASA, the MPO content is higher on day 6; the TNFa content is higher on day 4.</p><p>In EC, the effects of using rectal suppositories with vitamin D3 on clinical signs, the size of the ulcerative defect, the content of MPO and TNFa in the lesion are comparable to the effects of using rectal suppositories with 50 mg of 5-ASA; more pronounced with respect to the dynamics of the cellular composition of the lesion of the colon.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>экспериментальный колит</kwd><kwd>витамин D3</kwd><kwd>индекс активности болезни</kwd><kwd>MPO</kwd><kwd>TNF-α</kwd><kwd>5-аминосалициловая кислота.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>experimental colitis</kwd><kwd>vitamin D3</kwd><kwd>disease activity index</kwd><kwd>MPO</kwd><kwd>TNF-α</kwd><kwd>5-aminosalicylic acid</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">Del Pinto R., Ferri C., Cominelli F.
