background and aims. cigarette smoke can induce oral cancer by its free radicals and oxidative damage. salivary antioxidants system is believed to have an important role in defense mechanisms against oxidative stress. this study was compared total antioxidant capacity (taoc) of saliva in smokers and nonsmokers. materials and methods. in this cross-sectional study, 30 male smokers with mean age ...

objective: active and passive smoking lead to the production of a number of oxidants and antioxidants with various adverse health effects compromising the immune system. tobacco use increases the production of free radicals as well. the purpose of this study was to determine the effects of passive smoking on total antioxidant capacity (tac) of serum and saliva in rats. methods: this experimenta...

background: cryopreservation of pre-antral follicles is a hopeful technique to preserve female fertility. the aim of the present study was to evaluate reactive oxygen species (ros) and total antioxidant capacity (tac) levels of mouse vitrified pre-antral follicles in the presence of alpha lipoic acid (ala). methods: isolated pre-antral follicles (140–150 µm in diameter) were divided into vitrif...

inflammation and pain induced by delayed onset muscle soreness (doms) can be induced by eccentric exercise or an unaccustomed activity. the condition can causes problems in exercising and for athletes. the purpose of this study was to assess the effect of 150mg curcumin supplementation immediately after intensive eccentric exercise. evaluations were made for total antioxidant capacity (tac), mu...

This study aimed to compare the antioxidant content and antioxidant capacity of pulp and peel of two varieties of pomelo fruit (Tambun White and Tambun Pink). Antioxidants including total phenolic content, total flavonoid content and ascorbic acid content were determined using Folin-Ciocalteu reagent assay, aluminium chloride colorimetric assay and AOAC method, respectively. Antioxidant capacit...

Ethanolic extract of leaves of Elaeocarpus ganitrus was analyzed for their total antioxidant capacity, reducing power, metal chelating, ABTS+ (2, 2-azinobis-(3-ethylbenzothiazoline-6-sulphonate) radical scavenging and hydroxyl radical scavenging activities. The extract at 500 ?g/ml showed maximum Iron chelating activity (76.70%) followed by the scavenging of the ABTS+ radical (55.77%) at the sa...
