Comparison of immunohistochemical findings after warm ischemia experiments. Nitrotyrosine and 4-HNE staining in the myocytes is less expressed in the San 20 (a, b) group when compared to San 5 (c, d), Ang (e, f), and KRS (g, h). Note positive endothelial cells (arrowhead: images (a), (c), and (e)), and a mastocyte (arrow: image (g)) as positive internal control. Original magnification 400x.
