Introduction The antioxidant capabilities of foods, cosmetics, supplements and pharmaceutical agents has become of particular interest. This is the result of the evidence demonstrating the relationship of reactive oxygen/nitrogen species (ROS) with aging and pathogenesis. [1,2]. Living organisms: use of a fuel (ATP) whose production results in the formation of toxic compounds, and requires that...

Objective: There has been a growing interest in finding plants with biological active ingredients for medicinal application. Materials and Methods: Three colors of petals of Althaea officinalis (A. officinalis) flowers, i.e., pink, reddish pink, and white were examined for total antioxidant activity and flavonoids content. Results: The reddish pink flowers of A. officinalis have more antioxidant...

Peroxisomes are single membrane cell organelles with a diversity of metabolic functions. Here we studied the peroxisomal dysfunction and oxidative stress after 3-nitropropionic acid (3-NP) induced neurotoxicity and the possible protective effects of oxytocin. Adult male and female rats were subjected to Oxt and/or 3-NP treatment. The antioxidant enzymes, Superoxide dismutase (SOD) and Catalase ...

objective: ionizing radiation produces free radicals which induce dna damage and cell death. origanum vulgare leaf extract (ovle) is a natural compound and its capability of scavenging free radicals and its antioxidant activity have been demonstrated by many researchers. in this study, using micronucleus assay, radioprotective effect of ovle against clastogenic and cytotoxic effect of gamma irr...

background and objectives:hormozgan province is located in the south of iran, bordering waters of the persian gulf and oman sea. due to the antioxidant potential of plants which might be responsible for their medicinal properties, the antioxidant properties of four medicinal plants of the region were evaluated. methods: the antioxidant properties of chrozophora obliqua, daphne mucronata, salvia...

Curcumin has many pharmaceutical applications, many of which arise from its potent antioxidant properties. The present research examined the antioxidant activities of curcumin in polar solvents by a comparative study using ESR, reduction of ferric iron in aqueous medium and intracellular ROS/toxicity assays. ESR data indicated that the steric hindrance among adjacent big size groups within a ga...

This study investigated the antioxidant capacity and intestinal bacteria community in a mouse model of DSS-induced colitis. Twenty mice were randomly assigned to two treatments: mice with colitis induced by 5% DSS (DSS group) and mice with colitis induced by 5% DSS that also received melatonin treatment (MEL group). The DSS group showed significantly less antioxidant capability than the MEL gro...

clinical and epidemiological studies have shown that a diet rich in fruits and vegetables is associated with a decreased risk of cardiovascular diseases, cancers and other related disorders. these beneficial health effects have been attributed in part to the presence of antioxidants in dietary plants. therefore screening for antioxidant properties of plant extracts has been one of the interests...
