BACKGROUND One of the effects of burn injury is production of reactive oxygen species increasing general-structural damage. Such a condition is called oxidative stress. The purpose of this research was to find out whether oxidative stress is present in burnt children treated routinely and, if so, in which phase of the disease it is the most severe and how long it persists. MATERIAL AND METHOD...

The objective of this study was to investigate the effects of administration methods for on Garcinia cambogia on blood Garcinia cambogia concentration and antioxidative levels. Rats were divided into three groups: G1 (normal group), G2 (one administration of Garcinia cambogia extract 2,800 mg/kg b.w.), G3 (three separate administrations every 6 h of Garcinia cambogia extract 750, 850, and 1,200...

The aim of the present study was to assess whether BAY 11-7082, a nuclear factor-kappaB (NF- κ B) inhibitor, influences the level of reactive oxygen species (ROS), tumor necrosis factor alpha (TNF- α), and NF- κ B related signaling pathways in the liver. The animals were divided into 4 groups: I: saline; II: saline + endothelin-1 (ET-1) (1.25 μg/kg b.w., i.v.); III: saline + ET-1 (12.5 μg/kg b....

Systemic oxidative stress plays a role in many degenerative diseases. Although regular physical activity has been known as the most effective nonpharmacological intervention to alleviate the oxidative stress, the beneficial effect varies between individuals. We investigated whether NADPH oxidase p22phox gene C242T and A640G polymorphisms are associated with systemic oxidative stress level respo...

INTRODUCTION Salivary TBARS are a potential marker of oxidative stress in the oral cavity. Previous studies have found increased levels of salivary TBARS in various diseases. The aim of this study was to assess the variability of salivary TBARS in both genders. SUBJECTS & METHODS Saliva samples from thirty-eight healthy volunteers (18F & 20M) were collected every day during 30 day period. TBA...

enhanced oxidative stress in diabetes mellitus may contribute to the pathogenesis of diaetic complications. in this article, the stress oxidative generation has been studied in experimental diabetes by ferric reducing ability of plasma assay, a sensitive and simple method, and by other oxidative damage markers. the ferric reducing ability of plasma values as a total antioxidant capacity were si...

The effect of organic selenium feed supplements on the activities of antioxidant enzymes and on lipid peroxidation was investigated in the chicken heart muscle during fattening. The experiment was carried out on Ross 308 broiler chickens of both sexes, either on standard diet (control group, n = 30) or receiving organic selenium supplementation (Sel-Plex, Alltech) in the standard diet (experime...

The aim of this study was to compare the indices of glutathione antioxidant system and oxidative damage level in resistance trained and untrained subjects and to assess the antioxidant action of alpha-lipoic acid in trained men exposed to muscle-damaging exercise. Thirteen trained and twenty untrained men (NT) participated in the comparative study. Then trained men were randomly assigned to T(C...

BACKGROUND Systemic oxidative stress in horses with recurrent airway obstruction (RAO) is poorly characterized. OBJECTIVES The goal of this study was to investigate whether equine RAO is associated with systemic disturbances in the oxidant-antioxidant equilibrium. ANIMALS Seven healthy horses and 7 horses with symptomatic RAO. METHODS A prospective study. Healthy and RAO-affected horses w...

Borage meal exerted a concentration-dependent antioxidant activity in a meat model system. At 2% (w/w), it inhibited (p 0.05) 2-thiobarbituric acid-reactive substances (TBARS), hexanal and total volatile formation in meat by 26.5, 30.5 and 18.6%, respectively. Antioxidant compounds in the meal were concentrated at optimum extraction conditions (in 52% ethanol at 74 C for 62 min) predicted by re...
