Этанольный, ацетоновые и гексан-ацетоновый экстракты (1 % в диметилсульфоксиде) эффективно поглощают диапазон УФ с наибольшей индукцией эритемы. На 4-е сутки после облучения УФ-А/Б наблюдаются выра женные бурые ожоги кожи спины, сильная эритема и отеки, образование струпа. В сыворотке крови значимо изменяются биохимические параметры – повышаются прооксидантная емкость, уровень нитрат- и нитрит-ионов NOx, окислительно модифицированных протеинов АОРР, активность глутатионпероксидазы GPx, снижается уровень SH-групп. Растворы экстрактов (5 %) в диметилсульфоксиде в разной степени проявляют фотопротекторное действие: морфологически – в минимизации отеков, эритемы, струпа; биохимически – в регуляции указанных параметров на уровне контроля. По совокупности биохимических и морфометрических па раметров наиболее перспективными фотопротекторами проявили себя ацетоновые экстракты. Прооксидантная емкость, GPx, АОРР (во всех случаях снижаются) и NOx показали неспецифичность и довольно высокую чувствительность и больше пригодны для оценки воспалительных и окислительных процессов. Наибольшую эффектив ность и адекватность поставленным задачам показал уровень протеиновых SH-групп.</p></abstract><trans-abstract xml:lang="en"><p>The reactivity of biological systems to UV-A/B and the photoprotective potential of skin applications of lichen extracts Hypogymnia physodes according to the biochemical parameters of blood and morphometric parameters of the skin were evaluated in vivo in laboratory mice. Ethanol, acetone and hexane–acetone extracts (1 % in dimethylsulfoxide) effectively absorb the UV range inducing the most erythema. On the 4th day after UV-A/Вirradiation, severe brown burns of the back skin, severe erythema and edema, scab formation were observed. In serum, there were significantly changed biochemical parameters – the prooxidant capacity, the level of nitrate/nitrite-ions NOx, advanced oxidation protein products AOPP, glutathioneperoxidase activity GPx increased, the level of SH-groups reduced. Solutions of extracts (5 %) in dimethylsulfoxide at  a different degree exhibited the photoprotective effect: morphologically – in minimizing the burn symptoms of the skin (edema, erythema, scab); biochemically – in the regulation of these parameters at the control level. According to the set of biochemical and morphometric parameters, the most promising photoprotectors were acetone extracts. The prooxidant capacity, GPx, AOРР (in all cases reduced) and NOx showed a non-specificity and rather high sensitivity and are more suitable for estimating inflammatory and oxidative processes. The highest efficiency and the adequacy to the tasks and the specifications are shown by the level of protein SH-groups.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ультрафиолетовое излучение</kwd><kwd>фотопротекторы</kwd><kwd>Hypogymnia physodes</kwd><kwd>прооксидантная емкость</kwd><kwd>глутатион</kwd><kwd>окислительная модификация протеинов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ultraviolet radiation</kwd><kwd>photoprotectors</kwd><kwd>Hypogymnia physodes</kwd><kwd>prooxydant capacity</kwd><kwd>glutathione</kwd><kwd>oxidative modification of proteins</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">Хлебникова, А.
