Биохимические исследования крови и мочи при этом позволяют описать общую картину состояния животного, проследить динамику изменения лабораторных показателей — маркеров повреждений органов при многократном введении препарата как для группы животных, так и индивидуально. Патоморфологические исследования органов и тканей позволяют на клеточном уровне представить характер повреждений. В ходе системного анализа полученных данных возможно однозначно выявить системы организма, наиболее подверженные токсическому действию препарата, а также оценить степень воздействия и обратимость эффектов. Учитывая высокую ценность получаемой фармакологической информации, необходимо уделять особое внимание надлежащему методологическому выполнению всех этапов подготовки и проведения упомянутых исследований, а также соответствующему анализу и интерпретации данных. Цель работы — методическое обобщение опыта проведения биохимических и патоморфологических исследований, накопленного в лаборатории лекарственной токсикологии ФГБНУ «НИИ фармакологии имени В.В. Закусова» при проведении хронических токсикологических экспериментов.</p></abstract><trans-abstract xml:lang="en"><p>Chronic toxicity studies are an integral part of the overall toxicological evaluation of drug candidates. Biochemical studies of blood and urine serve to describe the general picture of the animal’s condition and to trace the dynamics of laboratory markers of organ damage after repeated administration of the drug — both for a group of animals, as well as individually. Pathomorphological studies of organs and tissues make it possible to understand the nature of damage at the cellular level. A systemic analysis of the data obtained allows for accurate identification of the body systems that are most susceptible to the toxic effect of the drug, as well as for assessment of the degree of impact and the reversibility of effects. Considering the great importance of the obtained pharmacological information, it is necessary to pay special attention to proper methodological implementation of all the stages of preparation and performance of the mentioned studies, as well as to proper analysis and interpretation of the data. The aim of the paper was to summarise the methodology of biochemical and pathomorphological studies based on the experience obtained in the Drug Toxicology Laboratory of the Federal State Budgetary Institute «Zakusov Institute of Pharmacology» when conducting chronic toxicity studies.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>доклинические токсикологические исследования</kwd><kwd>хроническая токсичность</kwd><kwd>клинико-лабораторные исследования</kwd><kwd>биохимические исследования</kwd><kwd>патоморфологические исследования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>preclinical toxicology studies</kwd><kwd>chronic toxicity</kwd><kwd>clinical laboratory studies</kwd><kwd>pathomorphological studies</kwd><kwd>biochemical studies</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">Сорокина АВ, Алексеева СВ, Еремина НВ, Дурнев АД.
