Из-за способности вируса гриппа мутировать необходимо осуществлять постоянный поиск новых лекарственных препаратов, обладающих профилактическим и прямым противовирусным действием.</p><p>Цель исследования — изучение протективных противовирусных свойств препарата «Тимоген®», спрей назальный дозированный, на модели летальной гриппозной пневмонии у лабораторных животных.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Для эксперимента по изучению противовирусной активности тестируемых образцов лекарственных препаратов в отношении вируса гриппа H1N1 на белых половозрелых мышах были сформированы следующие группы (по 30 особей в каждой): две группы отрицательного контроля; две группы, получавшие Тимоген®, спрей (до и после заражения); одна группа животных, получавших Тамифлю®, и одна — Гексорал®. Оценивали летальность животных в ходе гриппозной пневмонии, а также проводили гистологический и морфометрический анализ.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Морфологическая картина лёгких животных коррелировала с их протективной активностью при анализе выживаемости животных. В наибольшей степени нормализация структуры ткани была выражена в группе животных, инфицированных вирусом, предварительно инкубированным с препаратом Тимоген®, спрей, назальный дозированный, и в группе с препаратом Тамифлю®. При этом в группе с препаратом Тимоген®, спрей вирусная нагрузка в лёгких была ниже на 1,5 и 1,2 порядка по сравнению с группой отрицательного контроля (3-и и 6-е сутки опыта, соответственно), что соответствует снижению интенсивности вирусной репродукции в 31,6 и 15,8 раз</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Due to the ability of the influenza virus to mutate, it is necessary to constantly search for new drugs with preventive and direct antiviral effects.</p><p>The aim of the study is to investigate the protective antiviral properties of the drug Thymogen®, a dosed nasal spray, on a model of lethal influenza pneumonia in laboratory animals.</p></sec><sec><title>Material and methods</title><p>Material and methods. White mature mice were selected for the experiment on the antiviral activity of the tested drug samples against H1N1 influenza virus; the mice were divided into the following groups (30 animals each): two negative control groups; two groups receiving Thymogen®, a dosed nasal spray (before and after infection); one group of animals received Tamiflu®, and one received Hexoral®. The mortality of animals with influenza pneumonia was assessed; histological and morphometric analyses were also carried out.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. The morphological picture of the lungs of animals correlated with their protective activity when analyzing the survival of animals. The normalization of tissue structure was pronounced the most in the group of animals infected with the virus, pre-incubated with Thymogen®, a dosed nasal spray, and in the group receiving Tamiflu®. Moreover, the viral load in the lungs was lower by 1.5 and 1.2 orders of magnitude in the group receiving Thymogen®, dosed nasal spray, compared to the negative control group (the 3rd and the 6th days of the experiment, respectively), which corresponds to a decrease in the intensity of viral reproduction by 31.6 and 15.8 times</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Тимоген®</kwd><kwd>назальный спрей</kwd><kwd>грипп</kwd><kwd>противовирусное действие</kwd><kwd>вирусная пневмония</kwd><kwd>вирус гриппа</kwd><kwd>мыши</kwd><kwd>доклиническое исследование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Thymogen</kwd><kwd>nasal spray</kwd><kwd>influenza</kwd><kwd>antiviral effect</kwd><kwd>viral pneumonia</kwd><kwd>influenza virus</kwd><kwd>mice</kwd><kwd>preclinical study</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках научно-исследовательской работы в ФБУН «Санкт-Петербургский научно-исследовательский институт эпидемиологии и микробиологии им.
