the present study aimed to evaluate the protective effect of crocin on gastric mucosal lesions caused by ischemia-reperfusion (i/r) injury in rats.forty male rats were randomly divided into sham, control (i/r injury) and three crocin-pretreated groups. to induce i/r lesions, the celiac artery was clamped for 30 min and then the clamp was removed to allow reperfusion for 3 h. pretreated-rats rec...

background: non-steroidal anti-inflammatory drugs (nsaid) have been associated with antioxidant property and have been shown to improve the circulating antioxidant status on daily dosing in different inflammatory conditions. the present study was conducted to investigate the antioxidant role of meloxicam in aluminum induced oxidative stress in rat brain. methods: in the in vivo experiments, spr...

a valuable composition of mentha piperita l. essential oil is menthol that is widely used fordifferent industries. the plants were treated with different concentrations of methyl jasmonate (meja) and after 24 h were evaluated for total soluble proteins, chlorophylls (a, b, and total), malondialdehyde, carbohydrates and antioxidant enzymes (superoxide dismutase and guaiacol peroxidase). variance...

background: there is growing evidence that damage to spermatozoa by reactive oxygen species (ros) play a key role in male infertility. objective: the aim of the present study was to assess the antioxidant status of seminal plasma by measuring total antioxidant capacity (tac) and activities of catalase and superoxide dismutase (sod) in men with asthenozoospermia, asthenoteratozoospermia and olig...

trichosanthes kirilowii, an important economic plant in china, is sensitive to chilling. to investigate the effect of abscisic acid (aba) treatment on the chilling tolerance of trichosanthes kirilowii maxim, different concentrations of aba were sprayed on trichosanthes kirilowii leaves and the resulting catalase (cat) and superoxide dismutase (sod) activities and the malondialdehyde (mda) conte...

selenium is an essential element for humans, therefore, adding it to plants is convenient for biofortification. thus, the aim of this work was to analyze experimentally the ability of sodium selenite to increase the concentration of se and modify the antioxidant activity in tomato plants. we used plants of the toro hybrid variety and applied three treatments: 0, 2 and 5 mg l-1 of selenium as so...

subclinical mastitis is considered as one of the most prevalent diseases in dairy cows, causing drasticloss in the dairy industry. oxidative stress, induced by reactive oxygen species (ros), is believed to be aprimary factor in various cattle diseases including mastitis, but there are few studies regarding the role ofros in subclinical mastitis. this study was undertaken to i) study the changes...

objective: electro-magnetic radiation (emr) is emitted from mobile phones. various researches have shown relationships between mobile phone emr exposure to cancer and neurologic damages. this study aims to investigate the effects of mobile phone emr on brain antioxidant enzyme activity and the learning process. methods: rat pups and their dames were exposed to emr for 3 h per day from p2 to p1...

diabetes mellitus (dm) is a chronic heterogeneous disorder and oxidative stress is a key participant in the development and progression of it and its complications. anti-oxidant status can affect vulnerability to oxidative damage, onset and progression of diabetes and diabetes complications. superoxide dismutase 2 (sod2) is one of the major antioxidant defense systems against free radicals. sod...
