22343. Ascorbic acid and total vitamin C concentrations in plasma, gastric juice, and gastrointestinal mucosa: effects of gastritis and oral supplementation. Full Text available with Trip Pro

Ascorbic acid and total vitamin C concentrations in plasma, gastric juice, and gastrointestinal mucosa: effects of gastritis and oral supplementation. Epidemiological evidence suggests that high dietary ascorbic acid reduces gastric cancer risk. It may do this by either reducing N-nitroso compound formation in gastric juice, or by scavenging reactive oxygen species in gastric mucosa. The aim of this study was to discover if potential ascorbic acid protection might be increased (...) by supplementation. Thirty two patients were supplemented with ascorbic acid, 500 mg twice daily for two weeks. Gastric juice, plasma, and upper gastrointestinal biopsy ascorbate concentrations were measured and compared with values in 48 unsupplemented patients. It was found that ascorbic acid and total vitamin C concentrations were considerably higher in biopsy specimens from oesophagus, body, antrum, duodenum, and rectum, compared with values in plasma or gastric juice. Plasma and mucosal concentrations were

22348. Potential health economic benefits of vitamin supplementation. Full Text available with Trip Pro

Potential health economic benefits of vitamin supplementation. This study used published relative risk estimates for birth defects, premature birth, and coronary heart disease associated with vitamin intake to project potential annual cost reductions in U.S. hospitalization charges. Epidemiological and intervention studies with relative risk estimates were identified via MEDLINE. Preventable fraction estimates were derived from data on the percentage of at-risk Americans with daily vitamin (...) %, respectively. For the conditions studied, nearly $20 billion in hospital charges were potentially avoidable with daily use of folic acid and zinc-containing multivitamins by all women of childbearing age and daily vitamin E supplementation by those over 50.

22352. Effect of modest vitamin E supplementation on blood glycated hemoglobin and triglyceride levels and red cell indices in type I diabetic patients. (Abstract)

Effect of modest vitamin E supplementation on blood glycated hemoglobin and triglyceride levels and red cell indices in type I diabetic patients. The glycation of proteins and elevated triglyceride (TG) levels are two of the major risk factors in the development of complications of diabetes. Previous studies have found some beneficial effects of supplementation of pharmacological doses (900-2000 IU/day) of vitamin E in Type II diabetic patients. This study examined whether supplementation (...) with a modest dose of vitamin E (100 IU/day) had any effect on blood glucose, glycated hemoglobin (GHb), TG or red cell counts in Type I diabetic patients.35 diabetic patients were supplemented with either DL-alpha-tocopherol (vitamin E) capsules (orally, 100 IU/day) or a placebo for 3 months in a double-blind clinical trial. Fasting blood was collected from each diabetic patient before and after vitamin E or placebo supplementation. Data were analyzed using paired "t" tests and the Wilcoxon Signed Rank

22353. The effects of vitamin C supplementation on biomarkers of oxygen radical generated damage in human volunteers with "low" or "high" cholesterol levels. (Abstract)

The effects of vitamin C supplementation on biomarkers of oxygen radical generated damage in human volunteers with "low" or "high" cholesterol levels. A human volunteer study was conducted to test the effect of vitamin C supplementation on biomarkers of oxygen radical-mediated damage in individuals with a range of serum cholesterol levels. A group of 48 non-smokers, 24 men and 24 women, was selected from a panel of over 100 volunteers to give as wide a range of serum cholesterol levels (...) products and ras p21 protein levels were measured in plasma. Lymphocytes were examined for DNA damage using the Comet assay and chromosome aberration test. The Comet assay was conducted with and without challenge with hydrogen peroxide and the chromosome aberration test with and without challenge with bleomycin. Vitamin C supplementation caused a statistically significant increase in plasma vitamin C concentrations and total antioxidant capacity but did not affect cholesterol levels or ras p21 protein

22354. Vitamin C supplementation and the common cold--was Linus Pauling right or wrong? (Abstract)

Vitamin C supplementation and the common cold--was Linus Pauling right or wrong? In 1970 Linus Pauling claimed that vitamin C prevents and alleviates the episodes of the common cold. Pauling was correct in concluding from trials published up till then, that in general vitamin C does have biological effects on the common cold, but he was rather over-optimistic as regards the size of benefit. His quantitative conclusions were based on a single placebo-controlled trial on schoolchildren (...) in a skiing camp in the Swiss Alps, in which a significant decrease in common cold incidence and duration in the group administered 1 g/day of vitamin C was found. As children in a skiing camp are not a representative sample of the general population, Pauling's extrapolation to the population at large was too bold, erring as to the magnitude of the effect. Nevertheless, Pauling's general conclusion that vitamin C has physiological effects on the common cold is of major importance as it conflicts

22355. Combined calcium and vitamin D supplementation reduces bone loss and fracture incidence in older men and women. (Abstract)

Combined calcium and vitamin D supplementation reduces bone loss and fracture incidence in older men and women. A recent supplementation study of 389 men and women, over the age of 65 years was conducted to address the impact of combined calcium and vitamin D supplementation on nonvertebral fracture incidence and maintenance of bone mass. Daily supplementation with 500 mg calcium and 700 IU vitamin D for 3 years moderately reduced bone loss at several sites and significantly decreased the rate (...) of nonvertebral fractures, compared with a placebo group. Optimal intake of both calcium and vitamin D may be an easily implemented strategy to maintain existing bone mass and reduce the risk of fracture in older men and women.

22356. Neuroendocrine responses to running in women after zinc and vitamin E supplementation. (Abstract)

Neuroendocrine responses to running in women after zinc and vitamin E supplementation. The study was undertaken to determine whether acute supplementation with zinc or vitamin E would modify neuroendocrine responses to physiologic stress.Specifically, the effects of exhaustive running on blood glucose, lactate, ACTH, cortisol, growth hormone, prolactin, catecholamine, and interleukin 6 (IL-6) concentrations were determined in 10 eumenorrheic runners after supplementation with zinc (25 mg (...) ), vitamin E (400 IU), or placebo. Subjects ran at 65-70% of their VO2max, to exhaustion, on a treadmill during the follicular phase of their menstrual cycles over three cycles.There were no significant differences associated with supplementation for any of the hormonal and metabolic measures. Exercise, however, significantly (P<0.05) increased plasma lactate, ACTH, prolactin, and catecholamine concentrations, all of which peaked immediately after exercise (POST). Plasma cortisol concentrations were

Effect of oral vitamin E (alpha-tocopherol) supplementation on vascular endothelial function in Type 2 diabetes mellitus. Vascular endothelial dysfunction, an early marker of atherosclerosis, has been demonstrated in Type 2 diabetes mellitus (DM). Vitamin E preserves endothelial function in animal models of diabetes and reduces cardiovascular risk. We examined endothelial function and the effect of vitamin E supplements in uncomplicated Type 2 DM.Forty-eight subjects with Type 2 DM and 21

22358. Effect of improved vitamin A status on response to iron supplementation in Pakistani infants. Full Text available with Trip Pro

Effect of improved vitamin A status on response to iron supplementation in Pakistani infants. We report an apparently protective effect of vitamin A in infants who received iron supplements (15 mg/d) for 3 mo. Those receiving iron showed increases in hemoglobin (8 g/L), ferritin (3.7 micrograms/L), and the acute-phase protein alpha 1-antichymotrypsin (ACT; 0.06 g/L). In both the placebo and iron-supplemented groups there were increases in plasma retinol, lutein, alpha-tocopherol, immunoglobulin (...) that these observations illustrate the importance of even small increases in dietary vitamin A or differences in vitamin A status in reducing the potentially toxic effects of iron supplements in persons in developing countries. These conclusions should now be confirmed with an intervention study to show that the benefits of vitamin A on iron status are due to reduced levels of infection.

22359. Fish oil supplementation with and without added vitamin E differentially modulates plasma antioxidant concentrations in healthy women. (Abstract)

Fish oil supplementation with and without added vitamin E differentially modulates plasma antioxidant concentrations in healthy women. The purpose of this study was to assess the effect of fish oil with or without vitamin E on plasma vitamin antioxidants. Thirty-three apparently healthy women aged 18-28 yr were recruited from the university environs, and 30 completed the double-blinded, parallel design supplementation trial. Blood samples were collected at baseline (week 0) and following 28 d (...) of supplementation with three capsules/d (0.8 g x 3) of either fish oil (FO) or FO with vitamin E (3 IU/g) (FOE). An additional blood sample was taken at day 91 (washout). Plasma antioxidant vitamins, fatty acid composition, and lipid peroxides were measured. Plasma alpha-tocopherol concentrations were increased significantly in both groups postsupplementation FO (P = 0.018) and FOE (P = 0.003) compared with baseline and washout values. Plasma retinol concentration was significantly increased (P = 0.034

Effect of dietary vitamin E supplementation on murine nasal allergy. Although many studies have reported the effects of dietary vitamin E on the immune response, none so far has assessed its role in nasal allergy.Female BALB/c mice were randomized into two groups and fed a 20% casein diet (control group, 50 mg vitamin E/kg diet) or this diet supplemented with 535 mg vitamin E/kg diet (vitamin E group, 585 mg vitamin E/kg diet) for 4 weeks. During the fifth week, the mice in each group were (...) divided into two subgroups to form a total of four treatment groups: group A (control), group B [control + toluene diisocyanate (TDI) sensitization], group C (vitamin E supplementation), and group D (vitamin E supplementation + TDI sensitization). Groups B and D were treated with two courses of intranasal application of 5% TDI in ethyl acetate, whereas groups A and C were treated with ethyl acetate alone. A week after second sensitization all groups were provoked by applying 2.5% of TDI in the vehicle
