  Background: Myeloperoxidase (MPO), a heme peroxidase enzyme produced by macrophages, is a marker of oxidative stress associated with increased cardiovascular events in Diabetes Mellitus (DM). In this study we hypothesize that MPO protein and gene expression is associated with increased Intra-Plaque Hemorrhage (IPH), iron deposition, plaque inflammation and neovascularization in DM atheroma. Methods: Twenty-six human aortas with advanced plaques (14 DM vs.12 No-DM) were studied. MPO protein and gene expression were quantified with immunohistochemistry and RT-PCR respectively. IPH was evaluated using H&E stain. Plaque iron was scored using Perl’s stain and graded Inflammatory cells and neovessels were manually counted in parallel sections using with (CD68 and CD3), and (CD34) using immunohistochemistry method.
