Protection by vitamin E against free radical-induced DNA mutations appears not to be an effective occurrence. On the other hand, in vitro evidence that different tocopherols slow down cell proliferation is an accepted observation. However, such an event may not be sufficient to result in beneficial clinical outcomes. Tocopheryl phosphate, a more active,

Vitamin C,Vitamin E and Flavonoids
2005All inflammatory processes include oxygen-activating processes where reactive oxygen species are produced. Intrinsic radical scavenging systems or compounds administered with food warrant metabolic control within certain limits. Antioxidants, which in many cases are free radical scavengers or quenchers of activated states, comprise a vast number of ...

Vitamin E deficiency in rats is associated with a greater susceptibility to lethal levels of ozone. Exposure of rats to sublethal ozone concentrations produces an accelerated decline in serum vitamin E levels. These findings are consistent with the possibility that lipid peroxidation is a mechanism of ozone toxicity.

[Vitamin A and vitamin E in dermatology].
Acta vitaminologica et enzymologica, 1985Vitamin A is necessary to maintain the integrity and the differentiation of epithelia of the skin and adnexa. Evident deficiency of vitamin A in chronic diseases, malabsorption and liver affections may result in skin xerosis, follicular keratosis, and metaplasia of mucous membranes.

Perhaps not surprisingly, vitamin E which has been touted to be potentially beneficial for a variety of disorders, including cancer, heart disease, and even Alzheimer's disorder, based on its function as an antioxidant has failed to withstand the scrutiny of recent, double-blinded, placebo-controlled clinical trials, including failure to provide ...

Sir—In their report, Mona Boaz and colleagues1 conclude that, in haemodialysis patients who have increased oxidative stress and are at high risk of atherosclerotic complications, 800 IU vitamin E daily reduces the risk of vascular accidents, including myocardial infarction.

The Indian Journal of Pediatrics, 1996
An improved understanding of its physiology has led to better therapeutic use of vitamin E in recent years. It is a physiological membrane bound antioxidant, protecting cell membrane lipids from oxidant damage by free redicals. Cholestatic liver disease, abetalipoproteinemia and ataxia with vitamin E deficiency are the common deficiency states where ...

Molecular Aspects of Medicine, 2007
The aim of this paper is to provide an overview of vitamin E metabolism. The topics covered include: major classes of vitamin E metabolites; their production pathways and route of excretion; possible biological activities of vitamin E metabolites; and use of vitamin E metabolites as markers of oxidant generation.

Clinics in Dermatology
Nutrition is essential for skin care, whether for its rejuvenation, recovery, or regeneration after trauma or surgery; yet it is often overlooked. Although many nutrients have well-demonstrated benefits, others, such as vitamin E, a liposoluble antioxidant used for over 50 years in dermatology, lack research and proof of their photoprotective and anti ...
