Данные литературы последних лет показывают, что воздействие тяжелых металлов является важным и недооцененным фактором риска, связанным с развитием атеросклероза и его последствий.</p></sec><sec><title>Ц е л ь</title><p>Ц е л ь . Изучение влияния хронической интоксикации солями различных тяжелых металлов (сульфат кадмия, нитрат никеля и нитрат кобальта) на показатели липидного обмена при экспериментальном атеросклерозе.</p><p>М а т е р и а л ы  и  м е т о д ы . Эксперименты проводились на 110 белых беспородных крысах-самцах. Атеросклероз моделировался по И.В. Савицкому. После моделирования атеросклероза животные подвергались хроническому воздействию солей тяжелых металлов (сульфат кадмия – 1 мг/кг, нитрат никеля – 2 мг/кг и нитрат кобальта – 2 мг/кг) через питьевую воду в течение 60 сут в четырех опытных сериях. Группой сравнения служили животные в исходном состоянии. Для оценки состояния липидного обмена изучали уровень общего холестерина(ОХ), триглицеридов (ТГ), липопротеидов низкой плотности (ЛПНП), липопротеидов высокой плотности (ЛПВП)и значения коэффициента атерогенности (КА).</p></sec><sec><title>Р е з у л ь т а т ы</title><p>Р е з у л ь т а т ы . После интоксикации различными тяжелыми металлами экспериментальных крыс с моделированным атеросклерозом отмечается выраженное усугубление нарушений липидного обмена – значительное увеличение уровня ОХ, ТГ, ЛПНП и КА с одновременным снижением уровня ЛПВП в сыворотке крови. Максимальные изменения изученных показателей липидного обмена отмечаются к 60-м суткам после интоксикации на фоне экспериментального атеросклероза.</p></sec><sec><title>З а к л ю ч е н и е</title><p>З а к л ю ч е н и е . Длительное воздействие тяжелых металлов (сульфата кадмия, нитрата никеля и нитрата кобальта) усугубляет нарушения липидного обмена, имеющие место при экспериментальном атеросклерозе. По степени выраженности патологических сдвигов в убывающем порядке следуют: сульфат кадмия → нитрат никеля →нитрат кобальта. Несмотря на то, что кобальт является одним из необходимых микроэлементов, его длительное поступление также приводит к усугублению нарушений липидного обмена при экспериментальном атеросклерозе.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>I n t r o d u c t i o n</title><p>I n t r o d u c t i o n . Recent literature shows that exposure to heavy metals is an important and underestimated risk factor related to the development of atherosclerosis and its consequences.</p></sec><sec><title>A i m</title><p>A i m . To study the effect of chronic intoxication with different heavy metal salts (cadmium sulfate, nickel nitrate, and cobalt nitrate) on lipid metabolism in experimental atherosclerosis.</p><p>M a t e r i a l s  a n d  m e t h o d s . The experiments were conducted on 110 outbred male albino rats. Atherosclerosis was modeled according to I.V. Savitsky. After modeling atherosclerosis, the animals were chronically exposed to heavy metal salts (cadmium sulfate – 1 mg/kg, nickel nitrate – 2 mg/ kg and cobalt nitrate – 2 mg/kg) via drinking water for 60 days in four experimental series. The comparison group consisted of intact animals. To assess lipid metabolism, total cholesterol (TCH), triglycerides (TG), low-density lipoproteins (LDL), high-density lipoproteins (HDL) and the values of the atherogenic coefficient (AC) were determined.</p></sec><sec><title>R e s u l t s</title><p>R e s u l t s . After intoxication with various heavy metals of rats with modeled atherosclerosis, a marked aggravation of lipid metabolism disturbances – a significant increase in the level of TCH, TG, LDL and AC with a simultaneous decrease in the level of HDL in the blood serum is revealed. The maximal changes in the parameters of lipid metabolism are observed by the 60th day after intoxication in experimental atherosclerosis.</p></sec><sec><title>C o n c l u s i o n</title><p>C o n c l u s i o n . Long-term exposure to heavy metals (cadmium sulfate, nickel nitrate and cobalt nitrate) exacerbates lipid metabolism disorders occurring in experimental atherosclerosis. According to the severity of pathological changes, the following are in descending order: cadmium sulfate → nickel nitrate → cobalt nitrate. Despite the fact that cobalt is one of the essential microelements, long-term exposure to it also leads to an aggravation of lipid metabolism disorders in experimental atherosclerosis.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>экспериментальный атеросклероз</kwd><kwd>тяжелые металлы</kwd><kwd>обмен липидов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>experimental atherosclerosis</kwd><kwd>heavy metals</kwd><kwd>lipid metabolism</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">Kobiyama K., Ley K.
