Antioxidant potential of leaves of three different species of Annona was studied by using different in vitro models eg., 1,1-diphenyl-2-picryl hydrazyl (DPPH), 2,2-azinobis-(3-ethylbenzothizoline-6-sulphonate) (ABTS), nitric oxide, superoxide, hydroxy radical and lipid peroxidation. The ethanolic extract of A. muricata at 500 microg/ml showed maximum scavenging activity (90.05%) of ABTS radical...

Ceruloplasmin (CP) was found to inhibit xanthine oxidase and ferritin-dependent peroxidation of phospholipid liposomes, as evidenced by decreased malondialdehyde formation. Ceruloplasmin was also shown to inhibit superoxide-mediated mobilization of iron from ferritin, in a concentration-dependent manner, as measured spectrophotometrically using the iron(II) chelator bathophenanthroline sulfonat...

The aim of the study was to investigate the antiperoxidative potential of ascorbic acid on cisplatin-induced lipid peroxidation, using some common laboratory markers. Goat liver was used as the lipid source. This in vitro evaluation was done by measuring the malondialdehyde, 4-hydroxy-2-nonenal, reduced glutathione, and nitric oxide content of tissue homogenates. The results suggest that cispla...

In an effort to understand the properties of asbestos fibres that might contribute to their being toxic, we incubated three different varieties of asbestos with phospholipid emulsions and looked for evidence of lipid peroxidation. Although all three types of asbestos were able to catalyse lipid peroxidation in the native state, this catalytic activity was inhibited by pre-washing of the asbesto...

Variation in lipid peroxidation levels are observed in different diseases. Many studies have shown that increased lipid peroxidation is associated with occurrence of some diseases. The aim of present effort was to review the role of lipid peroxidation in different clinically important diseases like diabetes, renal failure and hypothyroid function. This review showed that there is possible assoc...

The anthracenedione antineoplastic agents mitoxantrone and ametantrone are potent inhibitors of basal and drug-stimulated lipid peroxidation in a variety of subcellular systems (Kharasch, E. D., and Novak, R. F. (1983) J. Pharmacol. Exp. Ther. 226, 500-506). The mechanism by which these compounds function as antioxidants has been investigated using enzymic and chemical systems. Mitoxantrone and...

This study aims to investigate the biological activities related to hair loss of Equisetum debile extracts, including 5α-reductase inhibition, interleukin-6 (IL-6) secretion reduction, and anti-oxidation. E. debile extracts were obtained by maceration in various solvents. Crude extract (CE) was obtained by maceration in 95% ethanol. Chlorophyll-free extract (CF) was the CE which of the chloroph...
