objective: dm is a major medical problem in developing countries such as iran. blood sugar and lipids levels increase in diabetics exacerbates the onset of diabetes mellitus (dm) late complications. researchers have focused on herbal medicines improve sugar and lipid levels against side decreasing effects and possible inefficacy of chemical drugs. this study has assessed the effect of curcumin ...

background and aims. oral lichen planus is a common chronic inflammatory disease of the oral mucosa with malignant potential, pathogenesis of which is not still well known. free radicals and reactive oxygen species can play an important role in the pathogenesis of oral lichen planus. the aim of this study was to investigate salivary oxidative stress and antioxidant systems in patients with oral...

conclusions ehp was able to both reduce ldl-ch and to significantly decrease markers of oxidative stress and lipid peroxidation induced by hyperlipidemia. therefore, this herb, as a new pharmacological component, could be used to reduce certain blood lipids, lipid peroxidation, and aminotransferase markers. materials and methods thirty-two male rats weighting 200 ± 10 g were randomly divided in...

background: the increasing use of nuclear radiation for human welfare necessitates the search for new, safe, cost effective radio protectors not only for the personnel’s charged with the responsibility of working or testing with radiations in laboratories, but also for general public. with this view the present study has been undertaken to determine the deleterious effects of sub lethal gamma r...

the present study examined the antioxidant defense of glutamine on plasma and liver antioxidant status in broilers under phs with respect to changes in the levels of lipid peroxidation marker malondialdehyde (mda), total antioxidant status (tas) and the activities of anti peroxidative enzymes [superoxide dismutase (sod) and glutathione dependent antioxidant enzymes glutathione peroxidase (gpx)]...

objective: the present study was performed to compare the antioxidant effect of two different doses of zinc on lipid oxidation in type 2 diabetic patients. materials and methods: this double-blind, randomized controlled trial was conducted on 60 type 2 diabetic patients in yazd diabetes research center in 2008. the subjects were randomly allocated to receive zinc sulfate (iran, alhavi) either 2...

objective: oxidative stress is the result of an imbalance between free radical production and antioxidant defenses of the body. the use of antioxidants can have preventive effects in diabetes. the present study aims to show the effects of biarum bovei extracts on lipid profile, lipid peroxidation in streptozocin induced diabetic male rats. materials and methods: animals were randomly assigned t...

background: melatonin is a free radical scavenger. it has also antioxidant effects through its stimulatory actions on antioxidant system. objective: we conducted this study to examine the effect of different oral doses of melatonin on liver tissue. methods: we used 42 rats—6 rats in each group. group i served as the control group; group ii rats were pretreated with only melatonin; group iii was...

reactive oxygen species cause to release of dormancy in many plants such as sunflower seeds. this study investigated in order to evaluation role of reactive oxygen species germination and lipid proxidation in sunflower seeds. this study was performed in two separate experiments, each in a completely randomized design with factorial design with four replications.  in both experiments, uses from ...

background & aim: applications of synthetic antioxidant in food have side effects. in present study, the antioxidant potential of morus alba leaves, as natural antioxidant, was screened with cupric ion reducing assay (cuprac assay) and inhibition of lipid peroxidation. the aim of this study was to determine the total antioxidant activity of morus alba leaves. martial & methods: the fir...
