background: para-nonylphenol (p-np) is one of the environmental pollutants which cause reproductive system disorders. objective: the effects of vitamin e on ovary structure during its development in rats treated with p-np. materials and methods: 32 wistar female rats after mating were divided into 4 groups; control vitamin e (100mg/kg/day) p-np (250mg/kg/day) and p-np + vitamin e. the rats were...

background: vitamin e is an effective antioxidant, protecting cells against oxidative stress. objective: in this investigation the protective effect of vitamin e on the testis during development and spermatogenesis in rats exposed to sodium arsenite was evaluated. materials and methods: pregnant wistar rats were divided into 4 groups (n=8) control, sodium arsenite (8 mg/kg/day), sodium arsenite...

background: para-nonylphenol (p-np) is able to induce malformations in male reproductive system. objective: the aim of this study was to investigate the preventing role of vitamin e (vit.e) on sperm parameters and reproductive hormones in developing rats. materials and methods: pregnant rats were divided into 4 groups: control p-np vit.e and p-np+vit.e. treatments were performed on day 7 of ges...

background: bisphenol a (bpa), an environmental pollutant, can generate free radicals which damages the reproductive system. vitamin c is an antioxidant which may prevent the adverse effects of free radicals.objective: the aim was to investigate the effect of vitamin c on the ovary tissue in rats treated with bpa.materials and methods: in this experimental study, 24 female wistar rats (200±20 g...

the specificity of gentamicin for vitamin e deficiency-associated oxidative stresses in the renal proximal convoluted tubules is apparently related to its ability to increasingly facilitate generation of radical species in mitochondria. to determine the ways in which vitamin e manage the currently processes, we conducted a prospective study aimed to investigate the tubular preserving effect of ...

this investigation aimed to examine the protective function of vitamin e on rat bone marrow mesenchymal stem cells (mscs) treated with cadmium chloride. rat bone marrow mscs were extracted using flashing-out and cultured in dmem containing 10% fbs and 100 u/ml pen/strep. at the end of the third passage, cells were divided into 4 groups including control, cadmium chloride, cadmium chloride + vit...

conclusions according to the results of this study, vitamin e probably improves the harmful effects of formaldehyde on rat kidney tissue. results comparison of the control and formaldehyde groups with the vitamin e group revealed that there were significant differences in lumen size and nuclear color of proximal tubules in rats treated by vitamin e (p < 0.05). cell degeneration, lumen size, num...

background and objectives: vitamin e is a fat-soluble vitamin with antioxidant properties, which prevents tissue damages induced by free radicals by their neutralization. the aim of this study was to determine the effect of vitamin e on burn wound healing in rats. methods: in this study, 16 mature male rats weighing 260±10g were used in two groups of 8 each. after induction of anesthesia and sh...

This investigation aimed to examine the protective function of vitamin E on rat bone marrow mesenchymal stem cells (MSCs) treated with cadmium chloride. Rat bone marrow MSCs were extracted using flashing-out and cultured in DMEM containing 10% FBS and 100 U/ml Pen/Strep. At the end of the third passage, cells were divided into 4 groups including control, cadmium chloride, cadmium chloride + vit...
