Во всём мире отмечается стремительный рост числа людей, страдающих различными формами нарушения углеводного и липидного обмена. Современные исследования показывают, что транспорт, распределение, экскреция и накопление химических элементов при данных видах нарушения обмена изменяются по-разному и неодинаково влияют на дальнейшее состояние организма.</p></sec><sec><title>Цель исследования</title><p>Цель исследования. Оценить уровень макро- и микроэлементов в  сыворотке крови и печени, а также содержание металло-лигандных форм цинка в сыворотке крови у крыс линии Wistar в условиях высококалорийной диеты.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Для проведения эксперимента было отобрано 30 крыс-самцов, из которых были сформированы две группы: контрольная (n = 15) и опытная (n = 15). Животные контрольной группы получали основной рацион (270 ккал/100 г), а животные опытной группы – высококалорийную диету. В ходе эксперимента калорийность диеты опытной группы ступенчато увеличивалась от калорийности общего рациона. В ходе исследования оценивали массу тела, биохимические параметры крови и мочи. Анализ макро- и микроэлементов в образцах проводился с помощью метода массспектрометрии с индуктивно-связанной плазмой. Определение содержания индивидуальных соединений цинка в сыворотке крови проводился на комбинации хроматографа и масс-спектрометра.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что высококалорийная диета приводила к снижению уровня железа, хрома, йода, цинка, калия, кальция и увеличению содержания ванадия в сыворотке крови. В печени отмечалось снижение уровня лития и увеличение уровня кальция, ванадия, хрома, железа, цинка, кобальта. При оценке химических форм цинка в сыворотке крови фиксировалось процентное увеличение альбуминовой фракции на фоне снижения аминокислотных комплексов и низкомолекулярных форм цинка.</p></sec><sec><title>Заключение</title><p>Заключение. Полученные данные позволяют предположить, что высококалорийная диета приводит к дисбалансу химических элементов, что может служить одним из пусковых механизмом дизрегуляции ряда физиологических функций организма. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Worldwide, there is a rapid increase in the number of people suffering from various forms of carbohydrate and lipid metabolism disorders. Modern studies show that the transport, distribution, excretion and accumulation of chemical elements in these types of metabolic disorders change in different ways and affect the further functional state of the body differently.</p></sec><sec><title>The aim</title><p>The aim. To evaluate the level of macro- and microelements in the blood serum and liver, as well as the content of metal-ligand forms of zinc in the blood serum of a Wistar rat in a high-calorie diet.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Thirty male rats were selected for the experiment, from which two groups were formed: control (n = 15) and experimental (n = 15). The animals of the control group received the basic diet (270 kcal/100 g), and the animals of  the experimental group received a high-calorie diet. During the  experiment, the caloric content of the diet of the experimental group gradually increased from the caloric content of the total diet. During the study, body weight, biochemical parameters of blood and urine were evaluated. The analysis of macro- and microelements in the samples was carried out using inductively coupled plasma mass spectrometry. Determination of the content of individual zinc compounds in blood serum was carried out using a combination of a chromatograph and a mass spectrometer.</p></sec><sec><title>Results</title><p>Results. It was found that a high-calorie diet led to a decrease in the level of iron, chromium, iodine, zinc, potassium, calcium, and an increase in vanadium in blood serum. In the liver, there was a decrease in the level of lithium and an increase in  the  level of calcium, vanadium, chromium, iron, zinc, cobalt. When assessing the chemical forms of zinc in the blood serum, a percentage increase in the albumin fraction was recorded against the background of a decrease in amino acid complexes and low-molecular-weight forms of zinc.</p></sec><sec><title>Conclusion</title><p>Conclusion. The data obtained suggest that a high-calorie diet leads to an imbalance of chemical elements, which can serve as one of the triggers for dysregulation of a number of physiological functions of the body. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>микроэлементы</kwd><kwd>цинк</kwd><kwd>высококалорийная диета</kwd><kwd>избыточный вес</kwd><kwd>анализ содержания химических форм элементов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>trace elements</kwd><kwd>zinc</kwd><kwd>high-calorie diet</kwd><kwd>overweight</kwd><kwd>obesity</kwd><kwd>speciation analysis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при поддержке Российского научного фонда (проект № 22-25-00600).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Parhofer KG.
