six- to sixty months old children were studied in sirjan villages, divided into villages with or without a health house (hh). all the 893 children were medically examined and their food intake was assessed, using the 24-hours dietary recall method. ascorbic acid was determined in blood samples of 199 children. the results obtained are as follows: 1; the average vitamin c intake for all the chil...

the aim of this study was to investigate the effect of acute plyometric exercise with and without vitamin c supplementation on serum bdnf concentration in inactive men. in this semi-experimental study, 36 inactive men were randomly divided into four groups: vitamin+exercise (combination), vitamin c, exercise, and control. the exercise and combination groups performed the selected plyometric pro...

Background and Objective: Acrylamide is a highly soluble, widely- produced industrial and cytotoxic material. Some substances with antioxidant properties can ameliorate the deleterious effect of acrylamide. Vitamin C is necessary for the normal functioning of all cells and scavenging the free radicals due to the antioxidant properties. The present study was aimed to evaluate the effect of vitam...

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....

objective: critical macromolecules such as dna maybe damaged by free radicals that are generated from the interaction of ionizing radiation with biological systems. melatonin and vitamin c have been shown to be direct free radical scavengers. the aim of this study was to investigate the in vivo/in vitro radioprotective effects of melatonin and vitamin c separately and combined against genotoxic...

background: ascorbic acid (vitamin c) is one of the most commonly water soluble vitamins. extra energy is necessary for the exercise is not often attributed to intake of vitamin c, long-term and intense exercise can lead to oxidative damage to cellular compounds and also contribute to muscle fatigue and decrease exercise performance. limited data are available regarding to the efficacy of vitam...

Vitamin C, an antioxidant substance soluble in water, can react with amino groups of proteins to form schiff bases. As diabetes leads to glycation of various protein which has effect on structure and biochemical activity of them, the inhibition of this process seems very vital. For several years researches in this field have done their best to recognize the antidiabetics compounds. The aim of t...

this experiment was conducted to evaluate the effects of vitamin c on laying hens performance, egg characteristics and some blood parameters under normal rearing condition. one hundred and ninety two 24 - weeks - old laying hens diet were used in a completely randomized design with 4 treatments (0, 250, 500 and 750 mg vitamin c/kg diet) and 4 replicates for 105 days. although feed consumption, ...

Nitrite intoxication occurs frequently in ruminants and equines. The most common treatment of this disorder is administration of 1% methylene blue, although the use of some antioxidant agents e.g. vitamins and complementary treatment may also be useful. The aim of this study was to evaluate the in vitro antioxidative effects of some vitamins on methemoglobinemia induced by sodium nitrite. For t...
