in the present study, free-radical-scavenging and antioxidant activities of angipars™, an herbal extract which has been registered as a therapeutic drug for diabetic foot ulcer, were examined. we investigated the protective effect of angipars™ on cytotoxicity produced by exposure to h2o2 (300 µm) in hepg2 and a549 cell lines, using mtt assay, glutathione (gsh) content analysis, and lipid peroxi...

propionic acid (pa) is a short chain fatty acid, a common food preservative and metabolic end product of enteric bacteria in the gut. the present study was undertaken to investigate the effect of pa on liver injury in male rats. male western albino rats were divided into two groups. the first group served as normal control, the second was treated with pa. the activities of serum hepatospecific ...

background: oxidative stress plays an important role in the pathogenesis and progression of γ-irradiation-induced cellular damage, lung is a radiosensitive organ and its damage is a dose-limiting factor in radiotherapy. the administration of dietary antioxidants has been suggested to protect against the succeeding tissue damage. the present study aimed to evaluate the radioprotective efficacy o...

Introduction: The functions of the endoplasmic reticulum (ER) are important, particularly in the proteins’ synthesis, folding, modification, and transport. Based on traditional medicine and our previous studies on Zanthoxylum alatum in lipopolysaccharide-induced depressive behavior and scopolamine-induced impaired memory, the present study explored the role of hydroalcoholic extract of Z. alatu...

results the results revealed that metal urine concentration in welders was higher than controls but only the difference in chromium concentration was significant (p < 0.002). in the range of metals exposure, induction of oxidative stress for exposed group was observed by increase in urine mda (11.17 ± 4.23 and 4.83 ± 1.82 mm in welders and controls, respectively; p < 0.01). information of the m...

In this study we investigated the anti-inflammatory effects of chronic ethanol (EtOH) treatment on lipopolysaccharide (LPS)-stimulated C6 glioma cells. The cells were chronically treated with 200mM EtOH; coincubation with LPS and EtOH was obtained upon addition of 2μg/ml LPS to the incubation medium in the last 24h of EtOH exposure. We found that EtOH prevented the LPS-induced production of tum...

background: a high percentage of patients admitted to the intensive care unit (icu) have systemic inflammatory response syndrome (sirs) criteria. free radicals play an important role in initiation and development of sirs. the purpose of this study was to assess and compare the molecular changes of cellular antioxidant power in patients with sirs who received enteral nutrition (en) or en combine...

zno nps (zinc oxide nanoparticles) has generated significant scientific interest as a novel antibacterial and anticancer agent. since oxidative stress is a critical determinant of zno nps-induced damage, it is necessary to characterize their underlying mode of action. different structural and physicochemical properties of zno nps such as particle surface, size, shape, crystal structure, chemica...

OBJECTIVE Volume replacement in septic patients improves hemodynamic stability. This effect can reduce the inflammatory response. The objective of this study was to evaluate the effect of 7.5% hypertonic saline solution versus 0.9% normal saline solution for volume replacement during an inflammatory response in endotoxemic rats. METHODS We measured cytokines (serum and gut), nitrite, and lipi...

AIMS Oxidative stress mediated by reactive oxygen species (ROS) plays a striking role in the pathogenesis of heart failure, and antioxidants have been shown to attenuate cardiac remodelling in experimental models of cardiac damage. We recently showed that fibroblast growth factor 21 (Fgf21) is produced by the heart and exerts protective effects, preventing cardiac hypertrophy development. The a...
