The effects of oxygen inhalation for 48 h on the antioxidant capacity of lungs, livers, and brains in normal and vitamin E-deficient rats at various ages were examined. The activity levels of catalase, glutathione peroxidase, and superoxide dismutase, and the level of vitamin E in tissue homogenates were assayed as the indices of antioxidant capacity. Oxygen inhalation mostly decreased antioxid...

this study was designed to elucidate the effect of ascorbic acid on salivary total antioxidant capacity in smokers. in this single blind crossover clinical trial, the whole unstimulated saliva of 30 smokers, who were randomly divided into two groups, was collected. in the first phase after the saliva collection, one group of patients took 500 mg of vitamin c powder, for 3 weeks. then, saliva of...

background ducrosia anethifolia (da) is a medicinal plant traditionally used to treat a wide spectrum of illnesses. da contains a series of antioxidant compounds, including alpha-pinene, which give it a sedative and relaxing effect. in spite of these effects of da, the effects of da essential oil on anxiety and locomotor activity in open field tests have not yet been studied. in the present stu...

Thirty-seven China wines, produced from different geographical origins, were examined in this study. The antioxidant activity of wines was measured by different analytical methods: oxygen radical absorbance capacity (ORAC), reducing power, 2,2-azino-di-(3-ethylbenzothialozine-sulphonic acid) (ABTS), 2,2diphenyl-1-picrylhydrazyl (DPPH ), hydroxyl radical-scavenger activity, superoxide radical-sc...

Methanol 70% extract of Bauhinia racemosa aerial parts was tested for antimicrobial activity against different bacterial and fungal strains and for antioxidant activity and also total content of polyphenols with phytochemical analysis of the extract was determined. The results have showed that the extract has a significant antimicrobial activity, it inhibited the growth of Bacillus subtilis and...
