Фотобиологический эффект обусловлен фотодинамическими процессами с участием синглетного кислорода, генерируемого триплетно возбужденным сенсибилизатором. Вид зависимости выживаемости клеток от энергетической дозы указывает на то, что сенсибилизатором выступает билирубин, а не его фотопродукты.</p></abstract><trans-abstract xml:lang="en"><p>The studies performed in this work have shown that the radiation exposure to LED sources with an emission band maximum of about 465 nm corresponding to the absorption spectrum of bilirubin is able to cause damaging effects on animal cells in culture, being in a logarithmic growth stage, that have been pre-incubated with bilirubin. The photobiological effect is caused by photo dynamic processes with participation of singlet oxygen generated by a triplet-excited sensitizer. The type of cell survival depending on an energy dose indicates that the sensitizer serves as bilirubin but not its photoproducts. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>гипербилирубинемия</kwd><kwd>билирубин</kwd><kwd>фотосенсибилизатор</kwd><kwd>жизнеспособность клеток</kwd><kwd>МТТ -тест</kwd><kwd>фототерапия</kwd><kwd>синглетный кислород</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hyperbilirubinemia</kwd><kwd>bilirubin</kwd><kwd>photosensitizer</kwd><kwd>cell viability</kwd><kwd>MTT-test</kwd><kwd>phototherapy</kwd><kwd>singlet oxygen</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">The side effects of phototherapy for neonatal jaundice: what do we know?
