Figure 2 Histologic analysis of stented porcine coronary arteries after 28 days. Control (left), 100 µmol/l intracoronary iopromide paclitaxel (middle), and 200 µmol/l intracoronary iopromide paclitaxel (right). Stented coronary arteries were dissected from the formalin-fixed hearts, immersed in methylmethacrylate, and separated from the blocks with a coping saw, polished, and glued on acrylic plastic slides. Specimens were stained by the hematoxylin-eosin technique.
