Carboxymethylated glucan inhibits lipid peroxidation in liposomes.
Protective capabilities were studied of carboxymethylated (1-->3)-beta-D-glucan from Saccharomyces cerevisiae cell wall against lipid peroxidation in phosphatidylcholine liposomes induced by OH radicals produced with Fenton's reagent (H2O2/Fe2+) and also by microwave radiation using absorption UV-VIS spectrophotometry. A significant decrease in the conjugated diene production, quantified as Kle...
متن کاملDynamics of lipid peroxidation and antioxidion of alpha-tocopherol in membranes.
The dynamics of initiation and inhibition of lipid peroxidation by alpha-tocopherol (alpha-Toc) in membranes were investigated under biological conditions using phosphatidylcholine liposomes. First, I examined how superoxide generated in the bulk water phase is able to induce lipid peroxidation in the inner hydrophobic region of the membrane. Second, I studied the localization of the antioxidan...
متن کاملLiposomes as a Tool to Study Lipid Peroxidation in Retina
In living organisms, the oxidative stress is associated with several physiopathological affections (e.g. atherosclerosis, cancer, aging, neurodegenerative diseases). The oxidative stress is generally initiated by generation of reactive oxygen (ROS) and nitrogen species (RNS) (Halliwell & Gutteridge, 1990). ROS are continuously formed during cellular metabolism and are removed by antioxidants de...
متن کاملEffects of alpha-tocopherol on bacterial translocation and lipid peroxidation in rats with intestinal obstruction1
Purpose: Investigate if alpha-tocopherol has a protective effect on intestinal mucosa after obstruction and to evaluate the potential relations between lipid peroxidation and bacterial translocation. Methods: Ten rats were submitted to a sham laparotomy and six served as control group. A small bowel obstruction was done in sixteen animals and among them eight were pretreated with alpha-tocopher...
متن کاملEffect of alpha-tocopherol on lipid peroxidation in isoproterenol induced myocardial infarction in rats.
The effect of alpha-tocopherol pretreatment on lipid peroxidation and antioxidant status in isoproterenol induced myocardial infarction was studied in rats. Isoproterenol administered rats showed a significant increase in lipid peroxides in serum, heart and aorta. A significant increase in serum iron level with a significant decrease in iron binding capacity was also observed. The levels of ant...
