Abstract/OtherAbstract:
BACKGROUND: Activation of the complement system during myocardial ischemia and reperfusion results in its injury by multiple processes. The aim of this study was to evaluate contribution of innate, humoral mechanisms of nonspecific immune response in the myocardium subjected to infarction. Complement components and inhibitors were analyzed.
MATERIALS AND METHODS: Myocardial specimens from the archives of Chair and Department of Pathology, Medical University of Warsaw from 2010-2013, were used in the study. The examined proteins were evaluated using immunohistochemistry and immunofluorescence techniques. Tissues from 36 men and 14 women, mean age 65.02±14.65, were used in the study. The control group comprised healthy myocardial tissue collected from 10 subjects.
RESULTS: Statistical analysis of IHC reaction for proteins and inhibitors of the complement system and membrane attack complex demonstrated markedly higher immunoreactivity level in the myocardium with ischemic necrosis versus healthy myocardial tissue. A correlation analysis demonstrated statistically significant positive correlation between the examined proteins and inhibitors of the complement system and protectin and membrane attack complex. A significant correlation was not found between immunoreactivity of the examined proteins and clinical and morphological parameters of the analyzed cases.
CONCLUSIONS: Studies have shown that of the complement proteins presence on the surface of the myocardium subjected to ischemic destruction exacerbate.
