Контрольную группу составили 30 «условно» здоровых недоношенных. У обследуемых наиболее низким уровень оксида азота в пуповинной крови был в группе недоношенных с сочетанием внутриутробной пневмонии и респираторного дистресс синдрома (24,0±2,9 микроМ/л) и респираторным дистрессом (25,7±5,8 микроМ/л), (р&lt;0,05). Наиболее высокое содержание эндотелина-1 в пуповинной крови было у недоношенных тех же групп: 4,13±0,69 фМоль/мл и 3,02±0,28 фМоль/мл соответственно (р &lt; 0,05). На 7-е сутки уровень оксида азота венозной крови увеличился в 2 раза по сравнению с содержанием его в пуповинной крови, а уровень эндотелина-1 в венозной крови снизился. Полученные данные подтверждают наличие персистирующей легочной гипертензии у недоношенных новорожденных с заболеваниями легких.</p></abstract><trans-abstract xml:lang="en"><p>The main mediators of endothelial dysfunction (nitrogen oxide and endothelin-1) in premature newborns with respiratory disorders were researched: I group - 90 infants with congenital pneumonia, II group - 90 infants with respiratory distress syndrome, III group - 90 patients with congenital pneumonia and respiratory distress syndrome. The control group involved 30 ‘conditionally’ healthy premature infants. The lowest level of nitrogen oxide in cord blood was in the group of examined prematures with congenital pneumonia and respiratory distress syndrome (24.0±2.9 microM/l) and respiratory distress syndrome (25.7±5.8microM/l), (р &lt; 0.05). The highest content of endothelin-1 in cord blood was in prematures with congenital pneumonia and respiratory distress syndrome: 4.13±0.69 f Mole/mL and 3.02±0.28 fMole/mL respectively (р &lt; 0.05). On the 7th day of life the level of nitrogen oxide in venous blood increased twice in comparison with that in the cord blood. The level of endothelin-1 in venous blood became less as opposed to cord blood. These findings confirm the presence of long-lasting pulmonary hypertension in premature newborns with pulmonary disease.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дыхательные расстройства</kwd><kwd>недоношенные</kwd><kwd>эндотелиальная дисфункция</kwd><kwd>respiratory disorders</kwd><kwd>premature newborns</kwd><kwd>endothelial dysfunction</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">Баженов Д.В., Иванов С.Л., Мельне И.О.
