Апоптоз («апоптотическую лестницу») определяли в четырех клеточных популяциях лимфоузлов:</p><p>– в лимфоузлах с метастазами, не подвергавшихся ФДТ;</p><p>– в тех же лимфоузлах с метастазами после ФДТ;</p><p>– в лимфоузлах без метастазов, не подвергавшихся ФДТ;</p><p>– в тех же лимфоузлах без метастазов после ФДТ. Дизайн исследования включал интраоперационное разделение лимфоузлов на две части, одна из которых была сразу удалена и не подвергалась воздействию ФДТ, а вторая оставалась неудаленной и подвергалась ФДТ, затем через 60–90 мин после сеанса ФДТ также была удалена и исследована на апоптоз. В результате оказалось, что апоптоз обнаруживается только в лимфоузлах с метастазами, облучённых во время ФДТ. Полученные результаты указывают на тот факт, что в лимфоузлах зоны абдоминальной лимфодиссекции в результате местной интраоперационной ФДТ при злокачественных новообразованиях желудочно-кишечного тракта злокачественные клетки избирательно гибнут путём апоптоза, а незлокачественные клетки при этом в апоптоз не вступают (р&lt;0,01). Таким образом, полученные клинические данные позволили оценить таргетный эффект ФДТ и подтвердить безопасность фотодинамического воздействия на здоровые ткани лимфоидной системы, находящихся в зоне облучения.</p></abstract><trans-abstract xml:lang="en"><p>The method of DNA-electrophoresis was used to study apoptosis in the lymph nodes of the abdominal lymphodissection zone after local intraoperative photodynamic therapy (PDT) for the gastrointestinal cancers. Apoptosis (apoptotic ladder) was determined in the four cell populations of lymph nodes:</p><p>– in the lymph nodes with metastases that have not been irradiated;</p><p>– in the irradiated during PDT lymph nodes with metastases;</p><p>– in the lymph nodes without metastases that have not been irradiated;</p><p>– in the irradiated during PDT lymph nodes without metastases.</p><p>The implementation of this study was possible due to intraoperative division of lymph nodes into two parts, one of which was removed while another one intentionally wasn’t removed and was irradiated (in human). It was also removed 60-90 minutes after PDT treatment and examined for apoptosis. As a result, it was found that apoptosis is detected in the irradiated during PDT lymph nodes with metastases. The obtained results show the fact that in the lymph nodes of the abdominal lymphodissection zone tumor cells selectively die by apoptosis as a result of the local intraoperative photodynamic therapy (PDT) for the gastrointestinal cancers while in non-malignant cells apoptosis doesn’t occur after PDT (p &lt;0.01). Thus, the obtained clinical and experimental data made it possible to evaluate the target PDT effect and confirm the safety of the photodynamic effect on healthy tissues of the lymphoid system located in the irradiation zone.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фотодинамическая терапия</kwd><kwd>апоптоз</kwd><kwd>фотосенсибилизатор</kwd><kwd>цитологическое исследование</kwd><kwd>ДНК-электрофорез</kwd></kwd-group><kwd-group xml:lang="en"><kwd>photodynamic therapy</kwd><kwd>apoptosis</kwd><kwd>photosensitizer</kwd><kwd>cytopathological examination</kwd><kwd>DNA electrophoresis</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">Dougherty T.J.
