Животных (n=4–6) выводили из эксперимента на 1, 2, 4 и 6-й неделе от его начала. После получения печеночной ткани проводили гистологическое исследование, а с помощью полимеразной цепной реакции в реальном времени (ПЦР-РВ) выполняли анализ содержания мРНК генов, ассоциированных с развитием фиброза печени: трансформирующего ростового фактора β1 (TGF-β1), коллагена 1α1 (Coll1α1), матриксной металлопротеиназы-13 (ММР-13), тканевого ингибитора матриксной металлопротеиназы (TIMP-1) и гладкомышечного α-актина (α-SMA). Кровь забирали для измерения активности печеночных ферментов (АсАТ и АлАТ). HGF человека вводили в ткань печени методом гидропорации. Содержание в печеночной ткани мышей человеческого HGF определяли с помощью ПЦР. Для оценки степени развития фиброза печени использовали индекс Кноделя и морфометрический анализ.Результаты. На сновании расчета индекса Кноделя установлено формирование CCl4-индуцированного фиброза печени к 4-й неделе эксперимента. Цирроз печени формировался к 6-й неделе эксперимента. Эти данные согласовывались с результатами ПЦР-РВ и оценки активности печеночных ферментов. Морфометрический анализ показал, что после терапии HGF в исследуемой группе животных степень выраженности фиброза (%) была ниже по сравнению с контрольной группой. Эффективность трансфекции комплементарной ДНК HGF при использовании метода гидропорации была выше, чем при прямом способе введения в паренхиму органа.Выводы. Полученные результаты позволяют рассматривать генную терапию фактором роста гепатоцитов в составе невирусных векторов как один из перспективных методов лечения хронических заболеваний печени.</p></abstract><trans-abstract xml:lang="en"><sec><title>Aim of investigation</title><p>Aim of investigation. Studying of efficacy of genetic therapy of liver fibrosis at mice by human hepatocyte growth factor (HGF) and evaluation of potentials of hydroporation method for delivery of genetic complexes to the liver.</p></sec><sec><title>Material and methods</title><p>Material and methods. During experiment male mice of Balbc line received intraperitoneal injections of 30% perchloromethane (CCl4) diluted in oil in a dose of 1 ml/kg once per week. Animals (n=4–6) dropped from the experiment at the 1, 2, 4 and 6-th week from its onset. After obtaining liver tissue samples, histological study was carried out, and by real time polymerase chain reaction (RT-PCR) contents of mPNA of liver fibrosis-associated genes were analyzed: transforming growth factor β1 (TGF-β1), collagen 1α1 (Coll1α1), matrix metalloproteinase-13 (ММР-13), tissue inhibitor of matrix metalloproteinase (TIMP-1) and smooth-muscle actin α (α-SMA). A blood was extracted for assessment of liver enzymes activity (AST and ALT). Human HGF was injected into liver tissue by hydroporation method. Contents of human HGF in mice liver tissue was detected by PCR. For evaluation of stage of liver fibrosis Knodell index and morphometrical analysis was used.</p></sec><sec><title>Results</title><p>Results. According to Knodell index development of CCl4-induced liver fibrosis at the 4-th week of experiment was found. Liver cirrhosis developed at the 6-th week of experiment. These data correlated well to the RT-PCR results and evaluation of liver enzymes activity. Morphometrical analysis demonstrated, that after HGF therapy in the main group of animals the degree of fibrosis (%) was lower in comparison to that in the control group. Efficacy of transfection of complementary HGF DNA at application of hydroporation method was higher, than at direct method of injection into parenchyma of the organ.</p></sec><sec><title>Conclusions</title><p>Conclusions. Obtained results allow to consider gene therapy by hepatocyte growth factor in composition of non-viral vectors as one of perspective methods of treatment of chronic liver diseases.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фиброз печени</kwd><kwd>цирроз печени</kwd><kwd>генная терапия</kwd><kwd>трансфекция</kwd><kwd>фактор роста гепатоцитов</kwd><kwd>гидропорация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>liver fibrosis</kwd><kwd>liver cirrhosis</kwd><kwd>genetic therapy</kwd><kwd>transfection</kwd><kwd>hepatocyte growth factor</kwd><kwd>hydroporation</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">Внутренние болезни по Тинсли Р.Харрисону: В 7 т: Кн. 5: Болезни пищеварительной системы; Болезни иммунной системы, соединительной ткани и суставов: Учебное пособие для вузов /Под ред.
