Внутримозговое кровоизлияние (ВМК) часто сопровождается осложнениями со стороны дыхательной системы. Одним из методов, способствующих коррекции постинсультных осложнений, является применение иммуносупрессивного препарата финголимода. Цель исследования – изучить нереспираторные функции легких при экспериментальном ВМК на фоне применения финголимода. Материалы и методы. Животные были разделены на 3 группы: 1-я – ВМК, 2-я – ВМК на фоне введения финголимода, 3-я – контроль. ВМК моделировали введением 160 мкл аутологичной крови в латеральный желудочек мозга (P=0,6; D=1,5; V=3,5). Финголимод (FTY 720, Sigma) вводили спустя 1 ч после ВМК (внутрибрюшинно, 1 мг/кг). У животных исследовали биохимические и функциональные параметры сурфактанта легких: методом тонкослойной хроматографии оценивали фракционный спектр фосфолипидов, методом Вильгельми изучали поверхностную активность сурфактанта. Гравиметрическим методом определяли показатели водного обмена, кровенаполнения легких. По количеству стабильных конечных метаболитов – нитратов и нитритов – оценивали уровень NO крови. Результаты. Показано, что экспериментальное ВМК вызывает снижение на 9 % индекса стабильности альвеол, уменьшение на 25 % общего содержания альвеолярных фосфолипидов, а также изменение их фракционного состава: на 68 % снижается уровень основной поверхностно-активной фракции – фосфатидилхолина, на 151 % возрастает количество фосфатидной кислоты, на 163 % – лизофосфатидилхолина. Помимо этого, экспериментальное ВМК сопровождается отеком легких на фоне повышения органного кровенаполнения и увеличения NO крови. Введение финголимода не влияет на поверхностную активность сурфактанта, но полностью коррегирует водный баланс, кровенаполнение легких и содержание NO крови.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. Intracerebral hemorrhage (ICH) is frequently accompanied by respiratory system complications. One of the correction method of post stroke complications is administration of immunosuppressive drug fingolimod. Theobjective of the study is to investigate non-respiratory lung functions in experimental ICH during fingolimod treatment. Materials and methods. Animals were divided into 3 groups: group 1 with ICH, group 2 with ICH receiving fingolimod and group 3 as reference group. Intracranial hemorrhage was modelled by 160 μl autologic blood injection into lateral brain ventricle (P=0.6; D=1.5; V=3.5). Fingolimod (FTY 720, «Sigma») was administered within 1 hour after ICH (intraabdominal, 1 mg/kg). Biochemistry and functional parameters of the lung surfactant in animals were studied. Phospholipids fractions spectrum was assessed by thin-layer chromatography, superficial surfactant activity by Wilhelmi method. Parameters of water metabolism, pulmonary blood filling were studied by gravimetric method. Level of blood nitric oxide was estimated by amount of nitrates and nitrites stable terminal metabolites. Results. We revealed that experimental ICH causes a decrease of alveolar stability index by 9 %, decrease of total alveolar phospholipids content by 25 % and change of its fraction composition, i.e. decrease of major surface active fraction (phosphatidylcholine) by 68 %, increase of phosphatidic acid amount by 151 % and increase of lisophosphatidylcholine by 163 %. Besides that, experimental ICH is followed by lung edema on the lung blood filling background and increase of blood NO. Fingolimod administration does not affect surfactant surface activity but totally corrects water balance, lung blood filling and blood NO content.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>внутримозговое кровоизлияние</kwd><kwd>сурфактант</kwd><kwd>оксид азота</kwd><kwd>отек легких</kwd><kwd>финголимод</kwd></kwd-group><kwd-group xml:lang="en"><kwd>intracerebral hemorrhage</kwd><kwd>surfactant</kwd><kwd>pulmonary edema</kwd><kwd>nitric oxide</kwd><kwd>fingolimod</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">An SJ, Kim TJ, Yoon BW.
