PURPOSE This study was intended to investigate the effect of dexmedetomidine on oxidative stress response in pneumoperitoneum established in rats. METHODS Animals were randomized into three groups, group S: with no pneumoperitoneum, group P: with pneumoperitoneum established, and group D: given 100 mcg intraperitoneal dexmedetomidine 30 min before establishment of pneumoperitoneum. Plasma tot...
Periodontitis is a common inflammatory disease, which is initiated by bacterial infection and subsequently progressed by aberrant host response. It can result in the destruction of teeth supporting tissues and have an influence on systemic health. When periodontitis occurs, reactive oxygen species, which are overproduced mostly by hyperactive neutrophils, could not be balanced by antioxidant de...
Heat stress (HS) often blamed for suboptimal reproductive efficiency and is a worldwide problem, which inflicts heavy economic losses reflected in limiting the breeding season of rabbits to be normally from September to May in northern hemisphere and subtropical regions. The present experiment was conducted to study the effect of summer heat stress and the alleviating effect of some antioxidant...
Oxidative stress is related to an imbalance between the production of reactive species and the antioxidant defenses. In essence, oxidative stress has been defined as a disturbance in the pro-oxidant/antioxidant balance, leading to potential damage. It has been suggested that oxidative stress is involved in the etiology of several chronic diseases including cardiovascular disease, diabetes, canc...
Quetiapine, an atypical antipsychotic, has been employed to treat alcoholic patients with comorbid psychopathology. It was shown to scavenge hydroxyl radicals and to protect cultured cells from noxious effects of oxidative stress, a pathophysiological mechanism involved in the toxicity of alcohol. This study compared the redox status of the liver and the brain regions of prefrontal cortex, hipp...
Spermatozoa are very special cells and constantly exposed to the interphase between oxidative stress through high amounts of reactive oxygen species (ROS) and leukocytes, and reduction by means of scavengers and antioxidants. Considering the very special functions of spermatozoa as being the only cells with such high polarization and exerting their functions outside the body, even in a differen...
Rheumatoid arthritis (RA) is an autoimmune inflammatory disease whose pathogenic mechanisms remain to be elucidated. The oxidative stress and antioxidants play an important role in the disease process of RA. The study of oxidants and antioxidants biomarkers in RA patients could improve our understanding of disease pathogenesis; likely determining the oxidative stress levels in these patients co...
BACKGROUND Oxidative stress is a major mediator in the pathophysiology of several kidney diseases. The cellular damage is mediated by an alteration in the antioxidant status, which increases the concentration of reactive oxygen species (ROS) in the stationary state (oxidative stress). Therefore, interventions favoring the scavenging and/or depuration of ROS should attenuate or prevent the oxida...
background: this study aims to investigate the effect of antioxidants supplement on clinical outcomes and antioxidant parameters in rheumatoid arthritis (ra). methods: the pre‑post study was conducted on 40 female patients with ra in 12 weeks that taken daily one “selenplus” capsule contained 50 μg selenium, 8 mg zinc, 400 μg vitamin a, 125 mg vitamin c, and 40 mg vitamin e. about 5 ml venous b...
Article history: Received on: 20/04/2015 Revised on: 24/05/2015 Accepted on: 19/06/2015 Available online: 27/07/2015 Imbalance oxidative status occurs when oxidative stress is higher in the body due to the production of reactive oxygen species. Thus, antioxidants are needed to counteract the production of free radicals. Reoccurrence of oxidative stress in the lung cells will eventually lead to ...
