Изучить ультрамикроскопические особенности хромаффинных клеток мозгового вещества надпочечников крыс после 60-суточного воздействия тартразина.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Эксперимент проведен на 18 белых половозрелых крысах самцах. Животным контрольной группы ежедневно на протяжении 60 суток внутрижелудочно вводили 1 мл физиологического раствора, а крысам 1- и 2-й групп – эквивалентное количество тартразина в дозировке 750 и 1500 мг/кг. В соответствии с протоколом для электронно- микроскопического исследования проводили обработку образцов надпочечников. </p></sec><sec><title>Результаты</title><p>Результаты. Во 1-й группе в ядре темных и светлых эндокриноцитов преобладал гетерохроматин, распределенный в кариоплазме в виде умеренно плотных мелкозернистых скоплений; в цитоплазме выявлялись малого размера секреторные гранулы и слабо выраженная гранулярная эндоплазматическая сеть. В части митохондрий наблюдались разрушенные кристы и мембрана. В 2-й группе к вышеописанным изменениям добавлялось больше участков цитоплазмы с разрушенным содержимым между митохондриями.</p></sec><sec><title>Заключение</title><p>Заключение. Электронно-микроскопические изменения хромаффинных клеток мозгового вещества надпочечников, вызванные 60-суточным воздействием тартразина, указывают на снижение их функциональной активности, которая имеет прямую зависимость от его вводимой дозы тартразина.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. To study the ultramicroscopic features of chromaffin cells of the adrenal medulla of rats after 60-day exposure to tartrazine.</p></sec><sec><title>Material and methods</title><p>Material and methods. The experiment was carried out on 18 white mature rats. One ml of saline solution was administered in- tragastrically to animals of the control group daily for 60 days, while the rats of groups I and II were given an equivalent volume of tartrazine at a dosage of 750 and 1500 mg/kg, respectively. In accordance with the protocol for electron microscopy, the samples of adrenal glands were processed.</p></sec><sec><title>Results</title><p>Results. In the nucleus of dark and light endocrinocytes, heterochromatin predominated, distributed in the karyoplasm in the form of moderately dense fine-grained accumulations; in the cytoplasm, small secretory granules and a weakly developed rough endoplasmic reticulum were detected in group I. Some mitochondria have destroyed cristae and membrane. In group II, in addition to the changes described above, more areas of the cytoplasm with destroyed contents between the mitochondria were recorded.</p></sec><sec><title>Conclusion</title><p>Conclusion. Electron-microscopic changes in chromaffin cells of the adrenal medulla, caused by 60-day exposure to tartrazine, indicate a decrease in their functional activity which is directly dependent on the administered dose.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>надпочечник</kwd><kwd>мозговое вещество</kwd><kwd>хромаффинные клетки</kwd><kwd>ультраструктура</kwd><kwd>тартразин</kwd></kwd-group><kwd-group xml:lang="en"><kwd>adrenal gland</kwd><kwd>medulla</kwd><kwd>chromaffin cells</kwd><kwd>ultrastructure</kwd><kwd>tartrazine</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">Toxicological and Teratogenic Effect of Various Food Additives: An Updated Review / S.
