Объектом исследования явилась цельная кровь 5 больных БА легкой и средней степени тяжести контролируемого течения и 6 здоровых человек. Эксперимент in vitro проводили в стимулированной липополисахаридом (ЛПС) крови после инкубации в течение 30 минут. Затем вносили экспериментальное вещество N-ацил-этаноламин эйкозапентаеновой кислоты (NAE 20:5) в концентрациях 1,0, 5,0 и 10,0 µМ и инкубировали при 37ºС в течение 6 часов в режиме плавного перемешивания. Уровень оксилипинов исследовали методом иммуноферментного анализа.</p></sec><sec><title>Результаты</title><p>Результаты. Экспериментальное воздействие N-ацилэтаноламинов эйкозапентеновой кислоты имело следующие эффекты. Под действием этаноламина эйкозапентаеновой кислоты в концентрации 1 µМ снизился уровень PGE2 на 51% (p&lt;0,001) и увеличилось количество 15-HEPE на 32% (p&lt;0,05) в ЛПС-индуцированной плазме крови относительно значений до воздействия этаноламина. Также EPEA в данной дозировке показал тенденцию к увеличению уровня 18-HEPE. Воздействие EPEA в дозе 5µМ способствовало значительному снижению уровней LTB4 на 34% (p&lt;0,001), PGE2 на 51% (p&lt;0,001), а также увеличению уровней 12-HEPE на 33% (p&lt;0,01), 15-HEPE на 36% (p&lt;0,05) и 18-HEPE на 87% (p&lt;0,01). Под действием EPEA в дозировке 10 µМ было выявлено статистически значимое воздействие на весь спектр исследуемых оксилипинов. Так, применение данной дозы этаноламида в ЛПС-индуцированной крови продемонстрировало снижение концентрации LTB4 на 37% (p&lt;0,001), LXA4 на 22% (p&lt;0,05), PGE2 на 50% (p&lt;0,001), и увеличение концентрации 5-HEPE на 25% (p&lt;0,05), 12-HEPE на 76% (p&lt;0,001), 15-HEPE на 75% (p&lt;0,001), 18-HEPE на 155% (p&lt;0,001) относительно значений до воздействия EPEA.</p></sec><sec><title>Заключение</title><p>Заключение.

The search for new highly effective methods for the treatment and control of bronchial asthma is an urgent task in pathophysiology and pharmacology. A promising substance for the regulation of systemic chronic inflammation is N-acylethanolamine (EPEA) of eicosapentaenoic acid, which exhibits immunoregulatory properties.</p></sec><sec><title>Aim</title><p>Aim. To study the dose-dependent effect of eicosapentaenoic acid ethanolamine on the synthesis and metabolism of oxylipins by blood cells in patients with asthma under in vitro conditions.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The object of the study was the whole blood of 5 patients with controlled mild-to-moderate asthma and 6 healthy people. The in vitro experiment was carried out in lipopolysaccharide-stimulated blood after incubation for 30 minutes. Then the experimental substance N-acyl-ethanolamine of eicosapentaenoic acid (NAE 20:5) was added at concentrations of 1.0, 5.0 and 10.0 µM and incubated at 37ºC for 6 hours in gentle mixing mode. The level of oxylipins was studied by enzyme immunoassay.</p></sec><sec><title>Results</title><p>Results. Experimental exposure to N-acylethanolamines of eicosapentenoic acid had the following effects. Under the influence of ethanolamine of eicosapentaenoic acid at a concentration of 1 µM, the level of PGE2 decreased by 51% (p&lt;0.001) and the amount of 15-HEPE increased by 32% (p&lt;0.05) in lipopolysaccharide-induced blood plasma relative to the values before exposure to ethanolamine. Also EPEA at this dosage showed a tendency to increase the level of 18HEPE. Exposure to EPEA at 5µM resulted in a significant decrease in LTB4 levels by 34% (p&lt;0.001), PGE2 levels by 51% (p&lt;0.001), as well as an increase in 12-HEPE levels by 33% (p&lt;0.01), 15-HEPE by 36% (p&lt;0.05) and 18-HEPE by 87% (p&lt;0.01). Under the influence of EPEA at a dosage of 10 µM, a statistically significant effect on the entire spectrum of the studied oxylipins was revealed. Thus, the use of this dose of ethanolamide in LPS-induced blood showed a decrease in the concentration of LTB4 by 37% (p&lt;0.001), LXA4 by 22% (p&lt;0.05), PGE2 by 50% (p&lt;0.001) and an increase in 5HEPE concentration by 25% (p&lt;0.05), 12-HEPE by 76% (p&lt;0.001), 15-HEPE by 75% (p&lt;0.001), 18-HEPE by 155% (p&lt;0.001) relative to pre-EPEA values.</p></sec><sec><title>Conclusion</title><p>Conclusion. Further study of NAE fatty acids opens up new perspectives in the study of targeted methods for correcting the inflammatory response in bronchial asthma.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>бронхиальная астма</kwd><kwd>воспаление</kwd><kwd>этаноламины жирных кислот</kwd><kwd>оксилипины</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bronchial asthma</kwd><kwd>inflammation</kwd><kwd>fatty acid ethanolamines</kwd><kwd>oxylipins</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">Global Initiative for Asthma (GINA).
