introduction: iron deficiency anemia (ida) is the most common form of anemia and one of the most important health problems. iron supplementation for high risk groups can prevent ida and its complications in the community. we need to have a holistic approach to control ida with minimum cost and complications. considering the high prevalence rate of ida in iran, assessment of the effects of micro...

background: the aim of this study is to investigate the effect of vitamin a and c, as the agents that improve wound healing, on the adhesion formation process. materials and methods: sixty male wistar rats were used. they underwent midline laparotomy, for repair of a peritoneal injury, and were then assigned to four groups. group 1 (vitamin a) received 2000 units/kg intramuscular injection of v...

BACKGROUND AND OBJECTIVE Vitamin D is known to modulate thyroid neoplastic and autoimmune disease. We investigated the role of the vitamin D receptor (VDR) in normal thyroid development and function (thyrocytes and C cells). METHODS The thyroid phenotype of VDR knockout mice was studied in comparison to wild-type controls. The mice were fed a normal diet or a calcium-rich diet to circumvent e...

OBJECTIVES To test the hypothesis that antioxidant therapy would improve endothelial function in smokers. BACKGROUND Several studies have documented a beneficial effect of short-term oral or parenteral vitamin C on endothelial physiology in subjects with early arterial dysfunction. Possible long-term effects of vitamin C on endothelial function, however, are not known. METHODS We studied th...

Cultured skin substitutes have become useful as adjunctive treatments for excised, full-thickness burns, but no skin substitutes have the anatomy and physiology of native skin. Hypothetically, deficiencies of structure and function may result, in part, from nutritional deficiencies in culture media. To address this hypothesis, vitamin C was titrated at 0.0, 0.01, 0.1, and 1.0 mM in a cultured s...

In order to study the interaction of glutathione, vitamin C and vitamin E under hyperoxia (95 % oxygen) and hyperbaric oxygen (2.5 atmospheric pressure), 20 days old male Guinea pigs were fed with basal vitamin C free diet, while receiving a vitamin C supplement of either high concentration (50 mg/day) or low concentration (1 mg/day) for two weeks. Animals were than exposed to hyperoxia and hyp...

vitamin e is a potent reactive oxygen metabolites (rom) scavenger. it is a lipid-soluble vitamin and its main function is to protect polyunsaturated fatty acids against oxidative stress. twenty-five mechanically ventilated intensive care unit (icu) adult patients participated in a prospective randomized clinical trial receiving either placebo (10 patients) or 3 im doses (1000 iu each) of vitami...
