The objective of this study was to determine if competition intensity would have an effect on antioxidant status in horses before and during a three-day event. Body weight, body condition score, and blood was sampled from CCI2* (n = 19) and CCI3* (n = 23) horses before the start of dressage, 20 to 30 min following cross-country, and 18-24 h after cross-county. Data were analyzed using a PROC MI...

this study was performed to investigate the effect of ag+ as an elicitor on the activity of antioxidant enzymes, content of h2o2, accumulation of total tocopherol and antioxidant activity in hairy root cultures of silybum marianum (l.) gaertn. the hairy roots were treated with 2 mm ag+. the treated and non-treated hairy roots were harvested in the same time and data on h2o2 content, dpph, tocop...

the present study investigated the effects of e. coli lipopolysaccharide (lps) induced mastitis model in rat on the activity of antioxidant enzyme systems. to achieve this purpose, e. coli lps were infused into the mammary gland of 12 rats 72 hr postpartum and compared with 12 rats in control group infused intramammary placebo sterile pyrogene – free, physiological saline. the antioxidant activ...

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)]...

nitric oxide (no) is a highly reactive signaling molecule and plays a variety of physiological roles in plants. the research on the application of no to postharvest preservation of flowers and fruits shows great promise in recent years. however, the physiological mechanism of exogenous no to affect cut flowers is not very clear, and no donor treatment protected plants from damage by increasing ...

UNLABELLED  Objective. This study was aimed at identifying factors that affect the healing of foot ulcers among patients with type 2 diabetes, focusing on the evaluation of oxidative stress-one marker of the inflammatory response. METHODS A cross sectional study comprised of 96 subjects who were divided into 6 groups (16 subjects in each group). The groups were classified as non-diabetic con...

objective: oxygen free radicals may be implicated in the pathogenesis of ischemia reperfusion damage. the beneficial effects of antioxidant nutrients, as well as complex plant extracts, on cerebral ischemia-reperfusion injuries are well known. this study was conducted to determine the effects of the hydro-alcoholic root extract of withania coagulans on ca1 hippocampus oxidative damages followin...

In asthmatic patients, antioxidant defence is decreased. Although inhaled corticosteroids decrease asthmatic inflammation and modulate reactive oxygen species (ROS) generation, little is known of their effect on cellular antioxidant levels. The aim of this study was to evaluate the effect of inhaled beclomethasone dipropionate (BDP; 1,000 microg x day(-1)) on erythrocyte antioxidant levels in s...

A comparison of the erythrocyte (RBC) antioxidant metabolites and enzymes in nine marsupial and two monotreme species was carried out. Reduced glutathione (GSH) concentrations were comparable with those reported for other marsupial and eutherian species. An important finding was that the erythrocytes of the southern hairy nosed wombat regenerated GSH faster than the erythrocytes from its close ...

It has been believed that overproduction of free radicals and/or deficiency of antioxidant systems, and stress hormones may play a role in etiopathogenesis of many diseases, including gastric ulcer. This study evaluated whether there was an effect of adrenalectomy on lipid peroxidation [malondialdehyde (MDA)] and antioxidant [superoxide dismutase (SOD), glutathione peroxidase (GPX) and glutathi...
