ВГПН представляют особую психологическую и медицинскую проблему, связанную с обширным неэстетичным изменением кожного облика пациента. В настоящее время существуют многочисленные методы их лечения, в т. ч. с использованием лазерного излучения. Однако они часто неэффективны и приводят к неудовлетворительным клиническим и эстетическим результатам, при этом частота осложнений в виде рубцовой деформации и рецидива иногда достигает 41%. В связи с этим проблема эффективного и корректного лечения данной патологии остаётся актуальной и требует дальнейшего исследования. Целью работы является экспериментальное медико-биологическое исследование особенностей воздействия «синего» лазерного излучения с длиной волны (λ) 450 нм на ткани лабораторных животных для его использования при лечении пигментных невусов, включая ВГПН. В работе использовали «синее» лазерное излучение (λ — 450 нм), генерируемое лазерным аппаратом «Лазермед 10-03» (ООО «Русский инженерный клуб», г. Тула, Россия). Экспериментальное медико-биологическое исследование in vitro выполнено на охлаждённых образцах печени и мышцах мини-свиньи и in vivo на пигментированной коже живой лабораторной крысы с изучением динамики регенеративного раневого процесса участков воздействия на разные сроки — сразу после воздействия и до 90 сут. Проведена морфометрическая оценка зон воздействия: глубина проникновения, характер коагуляционных изменений. На основании результатов выполненного экспериментального исследования определены оптимальные режимы «синего» лазерного излучения (λ — 450 нм) для прецизионного удаления различных пигментных образований кожи. Лазерное излучение с длиной волны 450 нм является перспективным для эффективного лечения пигментных образований кожи, включая ВГПН.</p></abstract><trans-abstract xml:lang="en"><p>Benign pigmented skin lesions, including congenital giant pigmented nevi (CGPN), are pathological formations located in various skin layers and consisting of melanocyte clusters. CGPN represent a serious psychological and medical problem associated with extensive unaesthetic changes in the patient’s skin appearance. These lesions are currently treated by various methods, including laser radiation. However, such methods often render ineffective and lead to unsatisfactory clinical and aesthetic results, with the incidence of complications in the form of scarring and recurrence sometimes reaching 41%. Therefore, the problem of effective and appropriate treatment of this pathology is relevant, deserving further research. In this work, we conduct an experimental biomedical study into the effect of blue laser radiation with a wavelength (λ) of 450 nm on the tissues of laboratory animals in order to determine its prospects in the treatment of pigmented nevi, including CGPN. Blue laser radiation (λ — 450 nm) was generated by an Lasermed 10-03 device (Russian Engineering Club, LLC, Tula, Russia). An experimental biomedical in vitro research was performed on chilled samples of the liver and muscles of mini-pigs and in vivo on the pigmented skin of live laboratory rats. The dynamics of the regenerative wound process in the exposure areas was studied at different periods, i.e., immediately after exposure and following up to 90 days. A morphometric assessment of the exposure areas was carried out in terms of penetration depth and coagulation changes. The results obtained allowed determination of optimal parameters of 450 nm blue laser radiation for a precision removal of various pigmented skin formations. Laser radiation with a wavelength of 450 nm is a promising treatment approach for pigmented skin lesions, including CGPN.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>«синее» лазерное излучение с длиной волны (λ) 450 нм</kwd><kwd>пигментные образования кожи</kwd><kwd>врождённый гигантский пигментный невус</kwd><kwd>экспериментальное исследование</kwd><kwd>морфологическое исследование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>450 nm blue laser radiation</kwd><kwd>pigmented skin formations</kwd><kwd>congenital giant pigmented nevus</kwd><kwd>experimental study</kwd><kwd>morphological study</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">Вулф К.
