Reproducibility of the results of physicochemical parameters of native material was assessed using thin-layer chromatography. Calibration of methods and scaling was implemented using exogenous surfactant solution.</p> <p><bold>Results.</bold> It was detected that for identification of phosphatidylcholine in the samples, it is necessary to introduce not less than 0.15 mcg of exogenous surfactant and for dipalmitoylphosphatidylcholine – from 0.5 mcg and more. The efficiency of PS sampling with the method of exhaled air barbotage varies from 30 % to 50 % from the volume of surfactant, excreted with one average statistical human expiration.</p> <p><bold>Conclusions.</bold> Sampling of native material using the method of exhaled air barbotage was performed. Tensiometric and chromatographic scales were compiled. Variability of sampling degree was noted. It was shown that if the conditions of storage and transport are observed, there are no marked changes in the material.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель.</bold> Изучить влияние условий сбора и хранения биопроб легочного сурфактанта (ЛС) в барботате выдыхаемого воздуха на его поверхностную активность и биохимическую структуру для разработки клинических рекомендаций по оценке состояния ЛС.</p> <p><bold>Материалы и методы. </bold>Исследованы емкости из стекла, фторопласта и пяти полимерных контейнеров методами тензиометрии. Оценка воспроизводимости результатов физико-химических параметров нативного материала проводилась с помощью тонкослойной хроматографии.

Эффективность сбора ЛС методом барботирования выдыхаемого воздуха варьируется в пределах от 30 до 50 % от объема сурфактанта, выделяемого при одном среднестатистическом выдохе человека.</p> <p><bold>Выводы.</bold> Осуществлен сбор нативного материала методом барботирования выдыхаемого воздуха. Составлены тензиометрическая и хроматографичекая шкалы. Отмечена вариативность степени сбора. Показано, что при соблюдении условий хранения и транспортировки в материале не происходит заметных изменений.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Pulmonary surfactant</kwd><kwd>pulmonary tuberculosis</kwd><kwd>methods for surface tension study</kwd><kwd>automatization of diagnostic methods</kwd><kwd>tensiometry</kwd><kwd>thin-layer chromatography</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Легочный сурфактант</kwd><kwd>туберкулез легких</kwd><kwd>методы исследования поверхностного натяжения</kwd><kwd>автоматизация диагностических методов</kwd><kwd>тензиометрия</kwd><kwd>тонкослойная хроматография</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was supported by the grant of the Russian Foundation for Basic Research 17-41-590095 p_a.</funding-statement><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке гранта РФФИ 17-41-590095 р_а.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Кейтс M.
