Relative Effects of α- and γ-Tocopherol on Low-Density Lipoprotein Oxidation and Superoxide Dismutase and Nitric Oxide Synthase Activity and Protein Expression in Rats

Abstract
Background: Increasing evidence suggests that vitamin E prevents the progression of ath erosclerosis by inhibiting platelet aggregation, monocyte adhesion. and improving plaque stability and vasomotor function. Recently, controversy has arisen as to the relative effects of α- and γ-tocopherol in modulating some mediators of atherosclerosis.
