chronic urticaria is the most common skin diseases, characterized by chronic cutaneous lesions which severely debilitates patients in several aspects of their everyday life. vitamin d is known to exert several actions in the immune system and to influence function and differentiation of mast cells, central role players in the pathogenesis of chronic idiopathic urticaria. this study was performe...

background: atopic dermatitis is a public health problem worldwide. increment of reactive oxygen species (ros) produc­tion may be one of the contributing factors of tissue damage in atopic dermatitis. the present study was designed to deter­mine the effect of vitamins e and/or d on erythrocyte superoxide dismutase and catalase activities in patients with atopic dermati­tis. methods: in a random...

background: stroke is a leading cause of death in developed countries. however, current therapeutic strategies for stroke have been largely unsuccessful. several studies have reported important benefits on reducing the risk of stroke and improving the post‑stroke‑associated functional declines in patients who ate foods rich in micronutrients, including b vitamins. folic acid, vitamin b6, and vi...

abstract objective: diabetic peripheral neuropathy (dpn) is one of the most common complications of diabetes. beside the known factors such as hyperglycemia in the pathogenesis of this complication, other etiologies may play role in the pathogenesis of this complication. the aim of this study was the evaluation of the role of serum vitamin d and vitamin b12 levels in this process. material and ...

maternal vitamin d deficiency is one of the major risk factors for neonatal vitamin d deficiency followed by neonatal hypocalcaemia. the aim of this study is to determine the relationship between delayed neonatal hypocalcaemia and maternal vitamin d deficiency. this is a descriptive cross-sectional study. target population of this study included all term and preterm neonates with delayed hypoca...

background: renal ischemia reperfusion injury may occur in a variety of clinical situations, following a transient drop in total or regional blood flow to the kidney. this study was performed to investigate the protective effects of different antioxidants such as vitamin c, vitamin e, hydrocortisone and combination of these agents against experimental renal ischemia-reperfusion injury. method:...

abstract background and aims: vitamins are essential constituents of our diet that longley have been known to influence the immune system. vitamin d3 and b9 have received particular attention in recent years as these vitamins have been shown to have an unexpected and crucial effect on the immune response. 1, 25(oh)2d3 metabolizing enzymes and vitamin d receptor (vdr) are present in many cell ty...

conclusion: this study showed positive effect of the 2000 iu/day oral vitamin d on the serum level elevation of this vitamin in reproductive women. results: at baseline the mean serum levels of vitamin d in the control group was 23.34 ± 15.87 nmol/l and in intervention group was 25.13 ± 18.46 nmol/l, that these values didn’t have any significant difference (p = 0.43), while after intervention, ...

the objective of this study was to evaluate quality of frozen-thawed bull semen processed with extenders containing vitamin c and e as antioxidants. pooled semen's were collected from 5 bulls and diluted to a concentration of 30 × 106 sperm/ml with citrate –egg yolk (cey) or tris – egg yolk (tey) extenders. the diluted semen was divided to 5 aliquots including control and 4 experimental groups....
