Фотодинамическая терапия – один из методов лечения, применяемых в  современной онкологии. Оценка эффективности фотосенсибилизаторов in vivo на  моделях опухолей является общепринятой, однако методика проведения  фотодинамической терапии у мышей не лишена недостатков. </p><p>Цель исследования – оценить эффективность фотодинамической терапии у мышей на модели опухоли Эрлиха при подкожной и внутрикожной инъекции опухолевых клеток. </p></sec><sec><title>Материал и методы</title><p>Материал и методы. Исследование проведено на мышах BalB/c обоего пола. В качестве фотосенсибилизаторов использовали препараты Фотодитазин и Радахлорин.  Для фотоактивации применяли лазерный аппарат Алод с длиной волны 662 нм. </p></sec><sec><title>Результаты</title><p>Результаты. Проведено сравнение фотодинамической терапии при подкожной и внутрикожной локализации опухоли Эрлиха. Показано, что в зависимости от  локализации и глубины инъекции опухоли Эрлиха в значительной степени различаются фармакокинетика (как интенсивность флуоресценции во времени, так и контрастность по отношению опухоль/окружающие ткани) и фармакодинамика (торможение роста  опухоли, выживаемость животных) фотосенсибилизаторов. Большая контрастность опухоль/окружающие ткани наблюдается при внутрикожной локализации опухоли. </p></sec><sec><title>Заключение</title><p>Заключение. Модель с внутрикожной локализацией опухоли Эрлиха может быть рекомендована для первичной оценки эффективности и позволяет использовать меньшее число животных в эксперименте. При планировании экспериментов по изучению фотосенсибилизаторов и оценке их результатов должны учитываться преимущества и недостатки разных способов моделирования опухоли у мышей.  </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Photodynamic Therapy is one of the treatment methods used in modern oncology. Evaluation of the efficacy in vivo of photosensitizers on tumor models is generally accepted, but the photodynamic  therapy technique in mice is not without drawbacks.</p><p>The purpose of the study was evaluation of the efficacy of photodynamic therapy in mice with Ehrlich tumor model after subcutaneous and intracutaneous injection of tumor cells.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. The study was conducted on BAL B/C mice of both sexes. Fotoditazin® and Radachlorin® were used as photosensitizers. For photoactivation, the Alod laser apparatus with a wavelength of 662 nm was used.</p></sec><sec><title>Results</title><p>Results. A comparison of photodynamic therapy with subcutaneous and intracutaneous localization of Ehrlich tumor was performed. It was shown that depending on the location and depth of inoculation of Ehrlich tumor, the pharmacokinetics (both the fluorescence intensity over time and the contrast ratio of the tumor/surrounding tissue) and pharmacodynamics (tumor growth inhibition, survival) of photosensitizers are significantly different. Higher contrast of the tumor/surrounding tissue is observed with intracutaneous localization of the tumor.</p></sec><sec><title>Conclusion</title><p>Conclusion. A model with intracutaneous localization of Ehrlich tumor can be recommended for a primary assessment of efficacy; it allows the use of fewer animals in the experiment. When planning experiments to study photosensitizers and evaluating their results, the advantages and disadvantages of different methods for modeling tumors in mice should be taken into account.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фотодинамическая терапия</kwd><kwd>опухоли Эрлиха</kwd><kwd>фотосенсибилизатор</kwd><kwd>модель</kwd><kwd>фотодитазин</kwd><kwd>радахлорин</kwd><kwd>мышь</kwd></kwd-group><kwd-group xml:lang="en"><kwd>photodynamic therapy</kwd><kwd>Ehrlich tumor</kwd><kwd>photosensitizer</kwd><kwd>model</kwd><kwd>Fotoditazin</kwd><kwd>Radachlorin</kwd><kwd>mice</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского фонда фундаментальных исследований (проект № 18-315-00224).</funding-statement><funding-statement xml:lang="en">The study was supported by a grant from the Russian Foundation for Basic Research (project No. 18-315- 00224).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Миронов А.Н., Бунатян Н.Д., Васильев А.Н., Верстакова О.Л., Журавлева М.В., Лепахин В.К., Коробов Н.В., Меркулов В.А., Орехов С.Н., Сакаева И.В., Утешев Д.Б., Яворский А.Н.
