It is proposed that superoxide dismutase may protect vascular tissue stimulated to produce superoxide and NO under pathological conditions by preventing the formation of peroxynitrite.

This review surveys cellular sources of free radicals and the reactions they can undergo and discusses cellular defenses and adaptive mechanisms.

Forms of hypertension associated with elevated circulating levels of angiotensin II may have unique vascular effects not shared by other forms of hypertension because they increase vascular smooth muscle .O2- production via NADH/NADPH oxidase activation.
Formation of nitric oxide-derived inflammatory oxidants by myeloperoxidase in neutrophils
The data reveal that NO2− may regulate inflammatory processes through oxidative mechanisms, perhaps by contributing to the tyrosine nitration and chlorination observed in vivo.
Endothelial Regulation of Vasomotion in ApoE-Deficient Mice: Implications for Interactions Between Peroxynitrite and Tetrahydrobiopterin
Reactive oxygen species may alter endothelium-dependent vascular relaxation not only by the interaction of O2·− with NO· but also through interactions between peroxynitrite and tetrahydrobiopterin.

It is shown that continuous NTG treatment is associated with increased vascular .-O2-production and consequent inhibition of NO and mediated vasorelaxation produced by both exogenous and endogenous nitrovasodilators.

Hypertension caused by chronically elevated angiotensin II is mediated in part by .O2-, likely via degradation of endothelium-derived NO, and may contribute to vascular disease in high renin/angiotens in II states.
