methylsulfonylmethane (msm) is a sulfur-containing compound commonly found in diet and known to reduce oxidative stress. this trial was conducted to determine whether single dose supplementation with msm attenuates post-exercise oxidative stress in healthy untrained young men. sixteen untrained men volunteered for this study. participants were randomized in a double-blind placebo-controlled fas...

this study aimed to investigate the effect of different levels of silymarin against lead induced oxidative stress in broiler chickens. therefore, 240 broiler chickens of ross 308 allocated to 24 experimental units in a completely randomized design with factorial 2x3 arrangements and four replicates of 10 birds. the experimental diets containing silymarin at 3 levels (0, 100, 200 mg/kg) and 2 le...

to study the effect of salinity stress on some physiological attributes of four grape cultivars in vineyards of urmia in iran, an experiment was carried out as factorial arrangement in randomized complete block design with four replications. experimental factors included: grape cultivars qazel ozum, qareh shireh, tabrzeh and dizmari, and salt concentrations 0, 25, 50 and 100 mmol l-1 and locati...

Vitamin E (毩-tocopherol) is fat soluble organic compound and commonly present in the cell membranes. This vitamin has the strong antioxidant properties and inhibits the lipid peroxidation created by the free hydroxyl and superoxide radicals. This vitamin protects the cell membrane of sperm cell from damages of ROS. In vitro studies have proved that the use of vitamin E improves the motility and...

Zinc is a necessary micronutrient in plants whose deficiency can alter essential functions in plant metabolism. High concentrations of Zn can be potentially toxic to plants causing phytotoxicity by the formation of reactive oxygen species. On the other hand, sodium nitroprusside (SNP), a donor of nitric oxide (NO) can protect cells from oxidative damage produce by reactive oxygen species. In th...

objective(s):long-term treatment with antipsychotics causes serious side effects such as tardive dyskinesia that characterized by abnormal movements in the orofacial region. oxidative stress in the brain specific area is implicated in the pathophysiology of tardive dyskinesia. in this study the protective effect of crocin on haloperidol-induced orofacial dyskinesia was evaluated. materials and ...

Objective(s): In this study, the effects of crocin against subchronic toxicity of diazinon (DZN) on systolic blood pressure (SBP) and heart rate (HR) were evaluated in rats. Materials and Methods: Rats were equally divided into 7 groups; control (corn oil), DZN (15 mg/kg), crocin (each group received 12.5, 25 or 50 mg/kg crocin plus DZN), vitamin E (200 IU/kg plus DZN) and crocin (50 mg/kg) tre...

Introduction: The aim of this study was to evaluate effects of 7 day glutamine supplementation on exercise-induced oxidative stress and muscle damage. Methods: Nineteen healthy, nonsmoking, young men were recruited to participate in this study. Participants were randomized in a double-blind placebo-controlled fashion into 2 groups: Glutamine (G group) (n=9) and placebo (P group) (n=10). Subj...
