Исследование проведено на 86 биоптатах опухоли пациентов с клинически установленным диагнозом «новообразование конъюнктивы». Контролем служила здоровая ткань из того же глаза. Проведено спектрофотометрическое определение оптической плотности реакционной смеси, содержащей биогенные наночастицы, сформированные в присутствии опухолей конъюнктивы и соответствующих парных образцов здоровой ткани из группы контроля. Полученные данные позднее подтверждались патогистологическим заключением.</p></sec><sec><title>Результаты</title><p>Результаты. Зафиксирован достоверно более высокий уровень формирования in situ биогенных наночастиц серебра в реакционной смеси со злокачественными опухолями конъюнктивы 3,0 ± 1,1 (n = 32), чем с доброкачественными 1,3 ± 0,2 (n = 54). Различий между разными типами доброкачественных опухолей не обнаружено. В образцах злокачественных опухолей показатели восстановительной активности у меланомы — 3,4 ± 1,0 (n = 14) и лимфомы — 2,8 ± 1,0 (n = 7) были достоверно выше, чем при плоскоклеточном раке — 2,0 ± 0,6 (n = 11), но достоверных различий между этими двумя типами опухолей не выявлено.</p></sec><sec><title>Заключение</title><p>Заключение. Метод спектрофотометрического определения восстановительной активности опухолей конъюнктивы может быть использован в дооперационной или интраоперационной диагностике благодаря быстроте получения результатов, что позволит оперативно определить объем хирургического вмешательства и оптимизировать тактику лечения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose: to compare the regenerative activity of benign and malignant conjunctival tumors.</p></sec><sec><title>Material and methods</title><p>Material and methods. The study was performed on 86 tumor biopsies from patients with a clinically diagnosed conjunctival neoplasm. Healthy tissues from the same eye were taken as a control sample. The optical density of the reaction mixture containing biogenic nanoparticles formed in the presence of conjunctival tumors and the corresponding paired healthy tissue samples from the control group was measured by spectrophotometry. The data obtained were later verified by a pathohistological analysis.</p></sec><sec><title>Results</title><p>Results. A significantly higher level of in situ formation of biogenic silver nanoparticles was recorded in the reaction mixture with malignant tumors of the conjunctiva (3.0 ± 1.1, (n = 32) compared to benign tumors (1.3 ± 0.2, n = 54). No differences were found between various types of benign tumors. In samples of malignant tumors, the indicators of recovery activity in melanoma (3.4 ± 1.0, n = 14) and lymphoma (2.8 ± 1.0, n = 7) were significantly higher than in squamous cell carcinoma (2.0 ± 0.6, n = 11), but no significant differences were found between the two types of tumors.</p></sec><sec><title>Conclusion</title><p>Conclusion. The method of spectrophotometric measurement of the regenerative activity of conjunctival tumors can be used in preoperative or intraoperative diagnostics thanks to the fact that the results can be obtained rapidly, which will help to quickly determine the extent of surgical intervention needed and optimize the treatment tactics.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>опухоль</kwd><kwd>конъюнктива</kwd><kwd>биогенные наночастицы</kwd><kwd>спектрофотометрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tumor</kwd><kwd>conjunctiva</kwd><kwd>biogenic nanoparticles</kwd><kwd>spectrophotometry</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">Бровкина А.Ф.
