A: The typical electron paramagnetic resonance (EPR) spectrum for a RCA segment exposed to N-tert-butyl-α-phenylnitrone (PBN). B: reactive oxygen species (ROS) production measured with EPR normalized by volume (mm3) of vessel tissue. C: typical time course of ROS formation in arterial tissue with L-012 enhanced chemiluminescence. D: ROS concentration averaged by time and normalized by dry weight of vessel tissue. E: ethidium fluorescence images. F: ROS production represented as area fraction of fluorescence. Values are means ± SD. SM, sham group. PA, PA banding group. *Statistically difference compared with control (P < 0.05).
