Recent studies dealing with oxygen free radicals and nitric oxide (NO) have demonstrated their implications in diseases such as inflammation, ischemia–reperfusion injury and several other cardiovascular dysfunctions [1–4].
Activated oxygen species, such as singlet oxygen, superoxide anion (O2–), hydrogen peroxide (H2O2) and hydroxyl radical (OH–) are highly unstable, extremely reactive and highly toxic [4]. Superoxide anions are usually required for the generation of H2O2 and OH–. The generation of free radicals is a normal physiological phenomenon, which is controlled by naturally occurring scavengers produced by the cell such as superoxide dismutase (SOD), glutathione peroxidase (GSHPx), catalase
