Background
Oxidative stress has been considered as a potential pathogenic
mechanism for initiation and progression of atherosclerotic
disease [1]. Excessive production of reactive
oxygen species, a mediator of the oxidative stress cascade,
leads to release of inflammatory cytokines, oxidation of
LDL and prothrombotic state, and finally results in
endothelial dysfunction and atherosclerotic vascular
lesions [2-4]. Adequate dietary, enzymatic and nonenzymatic
