Anti-oxidant mechanisms involved in gastroprotective effects of quercetin.
The anti-ulcerogenic and anti-oxidant effects of various flavonoids have been frequently reported. We investigated the cytoprotective properties of quercetin, a natural flavone, in gastric mucosal injury induced by 50% ethanol, since in this experimental model the pathogenesis of the lesions has been related with production of reactive oxygen species. The involvement of neutrophil infiltration ...
متن کاملAnti-Oxidant, Pro-Oxidant and Anti-Inflammatory Effects of Unpolished Rice Relevant to Colorectal Cancer
Colorectal cancer (CRC) is a major worldwide health problem owing to its high prevalence and mortality rates. Carcinogenesis in the colon is a multistage and multifactorial process. An imbalance between free radical exposure and anti-oxidant defense systems may leads to oxidative stress and attack of macromolecules which can alter signal transduction pathways and gene expression. Consequently, ...
متن کاملAntioxidant and Pro-oxidant Effects of Aminoguanidine on HepG-2 Hepatocellular Carcinoma Cell Line
Background and purpose: Hepatocellular carcinoma (HCC) is one of the most fatal cancers, so, proposing new anticancer agents is highly valuable. Production of reactive oxygen species (ROS) is increased in majority of cancers. Increase in ROS leads to cell damage and death. Aminoguanidine (AG) (pimagedine) is one of the compounds that can produce ROS at high concentrations. The present study was...
متن کاملComparative Effects of Copper, Iron, Vanadium and Titanium on Low Density Lipoprotein Oxidation in vitro
Oxidation of low density lipoprotein (LDL) has been strongly implicated in the phathogenesis of atherosclerosis. The use of oxidants in dietary food stuff may lead to the production of oxidized LDL and may increase both the development and the progression of atherosclerosis. The present work investigated the effects of some elements including: copper (Cu), iron (Fe), vanadium (V) and titanium (...
متن کاملOn the pro-oxidant effects of haemozoin.
Haemozoin (Hz) is a haem aggregate produced in some blood-feeding organisms. There is a general belief that Hz formation would be a protective mechanism against haem toxicity. Here we show that when aggregated into Hz, haem is less deleterious than its free form. When haem was added to phosphatidylcholine (PC) liposomes, there was an intense stimulation of oxygen consumption, which did not occu...
