The mechanism of Fe(2+)-initiated lipid peroxidation in a liposomal system was studied. It was found that a second addition of ferrous ions within the latent period lengthened the time lag before lipid peroxidation started. The apparent time lag depended on the total dose of Fe(2+) whenever the second dose of Fe(2+) was added, which indicates that Fe(2+) has a dual function: to initiate lipid p...

       The study was designed with an aim to evaluate the protective effects of reduced glutathione on cyclophosphamide induced lipid peroxidation and also changes in cholesterol content. Goat liver and white New Zealand rabbit were used as lipid source for the models. Lipid peroxidation study was performed by measuring the malondial...

The study was designed with an aim to evaluate the antiperoxidative potential of ascorbic acid on flutamide-induced lipid peroxidation. The study was performed in vitro using goat liver as lipid source. This evaluation was done by measuring the malondialdehyde and reduced glutathione content of the tissue as markers of lipid peroxidation. The study reveals the lipid peroxidation induction capac...

The brain is known to be sensitive to oxidative stress and lipid peroxidation. While lipid peroxidation has been shown to contribute to many disease processes, its role in psychiatric illness has not been investigated until recently. In this paper, we provide an overview of lipid peroxidation in the central nervous system as well as clinical data supporting a link between lipid peroxidation and...

the antioxidant properties of ruta graveolens l. were evaluated by two different methods; free radical scavenging using dpph and inhibition of lipid peroxidation by the ferric thiocyanate method. the ic50 value of the methanol extract in dpph inhibition was 200.5 μg/ml which was acceptable in comparison with bht (41.8 μg/ml). in thiocyanate method, the plant extract demonstrated activity as muc...

Peroxides are often used as models to induce oxidative damage in cells in vitro. The aim of the present study was to elucidate the role of lipid peroxidation in peroxide-induced cell death. To this end (i) the ability to induce lipid peroxidation in C6 rat astroglioma cells of hydrogen peroxide (H2O2), cumene hydroperoxide (CHP) and t-butyl hydroperoxide (t-BuOOH) (ii) the relation between pero...

background: lipid peroxidation is known to cause various impairments to sperm cells and may play a major role in the etiology of male infertility. asthenospermia is the main factor of male infertility and has significantly higher level of peroxidation than in normozoospermic males. materials and methods: using thiobarbituric acid (tba) assay procedure, we have determined the level of lipid pero...

The effect of alveolar oxygen tension on lung lipid peroxidation during lung ischemia was evaluated by using isolated rat lungs perfused with synthetic medium. After a 5-min equilibration period, global ischemia was produced by discontinuing perfusion while ventilation continued with gas mixtures containing 5% CO2 and a fixed oxygen concentration between 0 and 95%. Lipid peroxidation was assess...
