The object of this study was to determine the effect of prepartum supplementation of vitamin E with or without injective vitamin E and selenium (Se) on productive and reproductive performances and immune function in dairy cows. Sixty multiparous Holstein dairy cows were divided randomly into three groups at the end of gestation. Cows in each group received one of three treatments: (1) a single ...

1. Dietary supplementation with vitamin E reduces ischaemic events in patients with established coronary artery disease and improves endothelial function in cholesterol-fed rabbits. We examined whether such dietary supplementation with vitamin E improves endothelial function in patients with mild hypercholesterolaemia and coronary artery disease. 2. Twenty patients (total cholesterol 6.8 +/- 1....

The present study was conducted to compare the supplementation of natural (D-α-tocopherol) and synthetic (DL-α-tocopherol acetate) vitamin E on the growth performance, meat quality, muscular antioxidant capacity and genes expression related to oxidative status of broilers. A total of 144 1 day-old Arbor Acres broiler chicks were randomly allocated into 3 groups with 6 replicates of 8 birds each...

Reactive oxygen and nitrogen species are important signal molecules for adaptations to training. Due to the antioxidant properties of vitamin C and E, supplementation has been shown to blunt adaptations to endurance training. In this study, we investigated the effects of vitamin C and E supplementation and endurance training on adaptations in endogenous antioxidants and heat shock proteins (HSP...

The effects of tannic acid (TA) supplementation (0·02 %, wt/wt) were compared with the effects of clofibrate (CF) supplementation (0·02 %, wt/wt) in apo E-deficient (apo E) mice fed a AIN-76 semi-synthetic diet (normal diet) over 20 weeks. The mice were monitored for the modulation of hepatic mRNA expression and the activities of lipid-regulating enzymes. Both TA and CF supplementation lowered ...

Despite convincing in vitro evidence, a vitamin C-E interaction has not been confirmed in vivo. This study was designed to examine the effects of supplementation with either vitamin C or E on their respective plasma concentrations, other antioxidants, lipids and some haemostatic variables. Fasting blood was collected before and after intervention from thirty healthy adults in a double-blinded c...

Vitamin E is an antioxidant and may have a role in the protection of lung tissue against oxidative damage in cystic fibrosis. Previous studies of vitamin E status in cystic fibrosis have used plasma or serum concentrations, which vary with levels of carrier lipoproteins and hence may not reflect the concentration of vitamin E in tissues, where it is found in highest concentration in membranes. ...

The purpose of the research was to evaluate the effect of 4-week vitamin C and E supplementation on the markers of oxidative stress after exercise session in students. 30 non-athlete persons (25.21 ± 1.5 years, 173.42 ± 5.62 cm, 75.6±5.75 kg, VO2 max of 42.26 ± 1.11 ml/kg/min, and waist-hip ratio of 0.91 ±0.02 cm) volunteered for the study and were given vitamin C and E supplementation (1000 mg...

BACKGROUND Vitamin E and beta-carotene affect various measures of immune function and accordingly might influence the predisposition of humans to infections. However, only few controlled trials have tested this hypothesis. STUDY OBJECTIVE To examine whether vitamin E or beta-carotene supplementation affects the risk of pneumonia in a controlled trial. DESIGN AND SETTING The Alpha-Tocopherol...

Various studies have evaluated the antioxidant effects of vitamin E in the prevention or treatment of coronary artery disease (CAD). In vitro data suggest that vitamin E protects against oxidation of low-density lipoprotein and decreases the deposition of atherogenic oxidized low-density lipoprotein in arterial walls. Various observational and epidemiological studies also suggest a relationship...
