and represent an essential part of aerobic life and our metabolism. They are continuously produced by the body’s normal use of oxygen such as respiration and some cell mediated immune functions. Naturally, there is a dynamic balance between the amount of free radicals generated in the body and antioxidants to quench and/or scavenge them and protect the body against their deleterious effects. Th...

Oxidative stress is present in the liver of humans with steatosis and nonalcoholic steatohepatitis (NASH) and is a plausible mediator of cellular injury, inflammatory recruitment, and fibrogenesis. CYPs 2E1 and 4A are the microsomal oxidases involved with fatty acid oxidation. Both enzymes can reduce molecular oxygen to produce prooxidant species, which, if not countered efficiently by antioxid...

Background. Peptic ulcer disease has a leading place in the overall structure of digestive diseases: its prevalence is 6.00–10.0 % population developed countries, and mortality ranges from 6 to 9.7 per 100 thousand population. An important etiological factor this pathology neuropsychological background, prima­rily stress, which under repeated exposure becomes initiating physiological imbalance ...

Introduction: the imbalance between formation of reactive oxygen species (ROS) and ability cells to neutralize them is characterized as oxidative stress occurs in almost any pathological condition. Reactions convert ethanol acetic acid are accompanied by an increase ROS production. Given prevalence alcohol abuse contribution development conditions, we formulated aim our work: assess impact chro...

The present study was designed to assess the balance between antioxidant and prooxidant components and the oxidative stability of beef from cattle fed exclusively grazed pasture (PAS) or a barley-based concentrate offered indoors (CONC) for 11 mo, or fed grass silage indoors for a 5-mo winter period, followed for the remaining 6-mo summer period by grazed pasture (SiP) or by grazed pasture plus...

This is an in vivo study detailing the effects of catalase (CAT), superoxide dismutase (SOD) and the level of lipid peroxidation (LPO) products in liver homogenates from mice treated with alpha amanitin or phalloidin. Spectrophotometry was the main method used in this study. Our results showed that both toxins increased SOD activity, confirming an earlier in vitro study. In addition, our presen...
