Hence, we counted the immune cells (total and M2 macrophages and Treg lymphocytes), quantified pro- and anti-inflammatory cytokines (IL 1-β, IL-6, TNF-α, IL-10), measured parameters of cellular antioxidant enzymes superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx), and determined the levels of lipid peroxidation (TBARS) and protein oxidation (carbonyls) of the left ventricle of infarcted rats treated with PY at day 7 post-MI. This evidence concerns the gene IL6 and myocardial infarction.
