PURPOSE The vitamin E compound alpha-tocopherol inhibits fibroblast growth in vitro. To evaluate its potential benefit in preventing failure of glaucoma filtration surgery, we prospectively investigated the outcome of filtering surgery with postoperative dietary alpha-tocopherol supplementation. PATIENTS AND METHODS Thirty-nine patients (39 eyes) with primary open-angle glaucoma or pseudoexfo...

1. Light-grown cells of Euglena gracilis strain Z, var. bacillaris and 1224/5g contain phylloquinone, plastoquinone, alpha-tocopherol, alpha-tocopherolquinone and ubiquinone-9 (i.e. ubiquinone with 9 isoprene units/mol.). 2. The concentration (per g. dry wt.) of plastoquinone (and chlorophyll) in light-grown cells of strain Z was governed by the composition of the culture medium and age of the ...

BACKGROUND Vitamin E is well known as an antioxidant, and numerous studies suggest that it has a preventive role in atherosclerosis, although the mechanism of action still remains unclear. METHODS AND RESULTS The original aim of this study was to establish whether alpha-tocopherol (the most active form of vitamin E) acts at the earliest events on the cascade of atherosclerosis progression, th...

OBJECTIVE Alpha-tocopherol is the main vitamin E compound in humans, and has important antioxidative and immunomodulatory properties. The aim of this study was to study alpha-tocopherol concentrations and their relationship to disease activity in Norwegian multiple sclerosis (MS) patients. METHODS Prospective cohort study in 88 relapsing-remitting MS (RRMS) patients, originally included in a ...

The aim of this study was to examine associations between vitamin E status and cognitive performance in elderly people. The study subjects were a group of 34 men and 86 women, aged 65-91 y, who were free of significant cognitive impairment. Dietary intake was monitored using a "weighed food record" for 5 consecutive days including a Sunday. Serum levels of alpha-tocopherol and cholesterol were ...

BACKGROUND The incidence of obesity is increasing worldwide. The neuropathy associated with obesity, that is evident from disturbed nerve conduction, is one of the complications for which a number of treatment options are being considered. In this study, Simvastatin, a hydroxyl methyl glutaryl coenzyme A reductase inhibitor and alpha-tocopherol, a dietary antioxidant are compared for their effe...

BACKGROUND Evidence indicates that vitamin E has anticarcinogenic properties for gastrointestinal cancers; however, few studies have examined this with respect to exocrine pancreatic cancer. OBJECTIVE The objective was to examine whether vitamin E intake and serum alpha-tocopherol concentrations were prospectively associated with exocrine pancreatic cancer. DESIGN We conducted a cohort anal...

The serum vitamins A, E, and C (antioxidant vitamins) of 112 priest subjects, compared with 90 males and 119 females in a control group, were investigated. Subjects for the study were Thai volunteers who attended the Outpatient Department, Priest Hospital, Bangkok, for a physical check-up from July to September 2003. There was no age difference between the priest group and the controls. All ser...

Vitamin E (alpha-tocopherol or alphaT) has long been recognized as a classic free radical scavenging antioxidant whose deficiency impairs mammalian fertility. In actuality, alpha-tocopherol is one member of a class of phytochemicals that are distinguished by varying methylation of a chroman head group. Early studies conducted between 1922 and 1950 indicated that alpha-tocopherol was specific am...
