Оценена их способность индуцировать синтез фотоактивного протопорфирина IX  в здоровых тканях мочевого пузыря кролика при инстилляции растворов препаратов в различных концентрациях. Исследования показали, что ГЭ 5-АЛК вызывает индукцию и накопление ППIX в эпителии мочевого пузыря кролика в значительно меньших концентрациях, чем 5-АЛК. Так, достоверное увеличение интенсивности флуоресценции по сравнению с контролем удалось достичь при инстилляции в мочевой пузырь кролика раствора ГЭ 5-АЛК в концентрации всего 0,0001% (интенсивность флуоресценции 2,20±0,60 усл.ед.), а для 5-АЛК – только при использовании раствора в концентрации 0,3% (интенсивность флуоресценции 2,60±1,02 усл.ед.).</p></abstract><trans-abstract xml:lang="en"><p>A comparative experimental study of the specific activity of drugs based on 5-aminolevulinic acid (5-ALA) and its hexyl ester (5-ALA HE) was carried out. Their ability to induce the synthesis of photoactive protoporphyrin IX in the healthy tissues of the rabbit bladder when instilling the drug solutions at various concentrations has been estimated. It was shown that 5-ALA HE results in the induction and accumulation of PPIX in the rabbit bladder epithelium at much lower concentrations than 5-ALA. Thus, a significant increase in the fluorescence intensity in comparison with the control was achieved by instillation of 5-ALA HE solution in the rabbit’ bladder at a concentration of only 0.0001% (fluorescence intensity 2.20±0.60 a.u.), and for 5-ALA – only when using a solution at a concentration of 0.3% (fluorescence intensity 2.60±1.02 a.u.).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>флуоресцентная диагностика</kwd><kwd>протопорфирин IX</kwd><kwd>5-аминолевулиновая кислота</kwd><kwd>гексиловый эфир 5-аминолевулиновой кислоты</kwd><kwd>мочевой пузырь</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ﬂuorescence diagnosis</kwd><kwd>protoporphyrin IX</kwd><kwd>5-aminolevulinic acid</kwd><kwd>hexyl ester of 5-aminolevulinic acid</kwd><kwd>bladder cancer</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">Соколов В.В., Чиссов В.И., Филоненко Е.В. и др.
