For morphological study prepared paraffin sections, which were stained for morphological studies were prepared paraffin sections, which were stained with hematoxylin and eosin, by Van Gieson, Masson, on lipids with Sudan black B, according to Van Cossu. .To determine apoptosis, TUNEL method used in paraffin sections.

In process of progressing of atherosclerosis intensity and prevalence of apoptosis of coronary artery wall cells decreases, and processes of necrosis becomes predominant. Apoptosis of coronary artery wall cells is valuable in increasing the zones of atheromatosis, plaque destabilizations, and also increases the risk of thrombosis and ulcerations.</italic></p><p> </p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Цель исследования</italic></bold><italic>: изучить апоптоз отдельных клеточных компонентов сосудистой стенки коронарных артерий на различных морфологических стадиях атеросклероза.</italic><bold><italic> Материал и методы исследования</italic></bold><italic>. Исследования проводили на коронарных артериях, взятых от 52 умерших больных с атеросклерозом и ишемической болезнью сердца на различных стадиях атерогенеза.

Для определения апоптоза использовали метод TUNEL на парафиновых срезах.

По мере прогрессирования атеросклероза выраженность и распространенность апоптоза клеток коронарных артерий снижается, и преобладают процессы некроза. Апоптоз клеток коронарных артерий способствует расширению зоны атероматоза, дестабилизации бляшки, увеличивает риск развития тромбозов и образования изъязвлений.</italic></p><p> </p></trans-abstract><kwd-group xml:lang="en"><kwd>apoptosis</kwd><kwd>atherosclerosis</kwd><kwd>endothelial cells</kwd><kwd>smooth muscle cells</kwd><kwd>macrophages</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>апоптоз</kwd><kwd>атеросклероз</kwd><kwd>эндотелиоциты</kwd><kwd>гладкомышечные клетки</kwd><kwd>макрофаги</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
