the naturally occurring antioxidants: vitamin e, β-carotene and vitamin c are known to ameliorate theoxidative stress generated during various physiological and pathological conditions. the oxidative stress mayoccur at different sites, different times, and by different mechanisms in the animal system. lower levels ofthe anti-oxidant vitamins are associated with poor fertility and production lev...

background: the extremely low-frequency electromagnetic field (elf-emf), mainly emitted by electric transmission lines and household electronic appliances, is becoming a worldwide health risk. it is imperative to investigate the biological impacts of elf-emf and to identify products that are resistant to the radiation from 50 hz elf-emf. in this study, we investigated the biological impacts of ...

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:...

The objective of this study was to investigate the propensity of permethrin (PTN) to induce oxidative stress and changes in enzyme activities in liver of rainbow trout and its possible attenuation by vitamin C. Forty-eight fish were randomly assigned to 1 of 6 treatment groups and their livers were used for liver perfusion method: control (0 μgL-1 permethrin and 0 mgL-1 vitamin C), PTN-0.16 (0....

Emulsified systems are widely used for topical delivery with the aim of optimizing cutaneous absorption and offering a pleasant sensory. They also may provide protection active molecule against oxidation and/or degradation. The oil phase o/w emulsions consist liquid crystalline structures, especially lamellar structures which similar to those found in stratum corneum lipids. In present work, co...

purpose: to compare the efficacy and safety of topical mitomycin- c 0.01% versus dexamethazone phosphate 0.1% in patients with refractory vernal keratoconjunctivitis (vkc). methods: in this double blind randomized clinical trial, patients with refractory vkc were randomly assigned to treatment with topical mitomycin-c 0.01% eye drops (n=27) or dexamethazone phosphate 0.1% (n=27), four times dai...

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...

Pathophysiological mechanisms of cataract formation include deficient glutathione levels contributing to a faulty antioxidant defense system within the lens of the eye. Nutrients to increase glutathione levels and activity include lipoic acid, vitamins E and C, and selenium. Cataract patients also tend to be deficient in vitamin A and the carotenes, lutein and zeaxanthin. The B vitamin riboflav...
