Background: Varicocele (VCL) impacts the testicular tissue partly by down-regulating the antioxidant status accomplished with reducing the intra-testicular endocrine potential. It has been reported that the HSP70 families play a critical role in spermiogenesis. Therefore, current study was aimed to evaluate the protective effect of exogenous testosterone and vitamin E administration on VCL-indu...

thyrotoxicosis is a condition in which tissues are stimulated by increased secretion of thyroid hormone. the most common cause is diffuse toxic goiter and toxic multi-nodular goiter. for more reviews on this disease, the effects of hyperthyroidism on liver enzyme levels were studied. a total of 30 adult male wistar rats weighing about 190 g were purchased from the pasteur institute of iran. in ...

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...

the affinity of low density lipoprotein (ldl) to its receptor is very important, because most of ldl-uptake pathway is done by the ldl receptor and the change in size of ldl particle and the modification in its components may affects the ldl affinity for its receptor. in this study, the effects of lipophilic agents such as vitamin e and seven volatile oils: anethol, eugenol, geraniol, limonene,...

strenuous aerobic exercise is associated with oxidative stress and tissue damage. therefore, we have investigated the effects of exercise and eicosapentaenoic acid supplementation, with or without vitamin e, on the plasma levels of vitamin c, e and a, il-6, and glutathione peroxidase activity in basketball players. thirty four male basketball players, enrolled in the study. subjects received 2g...

Background: Free radical formation and oxidative stress might play an important role in the pathogenesis of Parkinson's disease (PD). In vitro data indicate that neuromelanin (NM) pigment is formed the excess cytosolic catecholamine that is not accumulated into synaptic vesicles via the vesicular monoamine transporter 2 (VMAT2). We designed this study to investigate the neuroprotective effects ...
