background myocardial injury caused by ischemia-reperfusion leads to cardiac dysfunction, tissue injury and metabolic changes. the production of reactive oxygen species (ros) and lipid peroxidation are accompanied by ischemia-reperfusion injury. objectives the aim of this study was to assess the cardio protective potential effects of crocin in comparison with vitamin e on antioxidant capacity i...

The effect of vitamin E on the contact sensitization responses induced in mice by 2,4-dinitrochlorobenzene (DNCB) was studied. Mice were fed a vitamin E-adequate or a vitamin E-deficient diet for 5 weeks. The amounts of thiobarbituric acid-reactive substances in the spleens and draining auricular lymph nodes of mice were decreased by dietary vitamin E. Dietary vitamin E prevented lipid peroxida...

Chronological changes of gonadotropin (FSH and LH) and testosterone concentrations in the serum were measured in vitamin E deficient rats to investigate the effects of vitamin E deficiency on the pituitary-gonadal function in rats. The receptor sites and association constant (Ka) for LH and the formation of cyclic AMP in the Leydig cells were also investigated. The results obtained in the prese...

abstract          background and objective: vitamins c and e are  the two main antioxidants involved in prevention of type 2 diabetes, by reducing oxidative stress. the aim of this study was to evaluate the effects of vitamins c and e supplementation independently, on serum levels of insulin, high sensitivity c-reactive protein (hs-crp) and resistin in people with type 2 diabetes.         metho...

apoptosis, a physiologic mechanism to eliminate unwanted cells, is also induced by ionizing irradiation, through production of free radicals. it has been demonstrated that antioxidants such as vitamin e are able to protect cells from damage caused by free radicals. taken together we found it reasonable to make an attempt to evaluate the protective effect of vitamin e against apoptosis. the irra...

one of the most important problems of fish is the short shelf lifebecause of the high unsaturated fatty acids. so, with the help of antioxidant compounds can be increased shelf life of fish. the aim of this study was to investigate the effect of vitamin e as a natural antioxidant to increase shelf life of rainbow trout fillet during storage at refrigerator temperature (4±1 0c). treatments were ...

to investigate the effect of vitamin e supplementation on the response of intercellular adhesion molecule-1 (icam-1) to exhaustive exercise, 16 active men were selected and divided into supplementation and placebo groups based on vo2max. the subjects in each group completed 65 minutes of exhaustive exercise after14 days of supplementation. blood samples were collected before supplementation and...

the purpose of this study was to evaluate the probable effects of the vitamin e addition in different levels to the extender of chicken semen on spermatozoa quality during storage of semen at 4°c for 0, 3, 6, 10 and 24 hours. eight young ross broiler breeder strain 308 roosters were used in this experiment. the collected semen from all roosters was mixed together and diluted with modified a rin...

320 one-day male broilers (ross 308) were divided in 4 treatments (with 4 replicate and 20 chicks for a replicate). all of broilers reared under a cold environmental temperature to induce ascites .experimental treatments were included 1: was fed a commercial corn-soybean meal- based diet meeting nrc (1994) including 1.2% arg and 40 iu of vitamin e/kg (control), 2: control with 400 iu of vitamin...

Vitamin D resistant rickets with alopecia is a rather rare heritable disease probably caused by a different variety of metabolic disorder of this vitamin. Disturbances of protoplasmic and unclear receptors for vitamin D metabolites in bones and intestinal cells have been proposed as basic mechanism; Alopecia is attributed to hypersensitivity to vitamin D; very much like what usually appears in ...
