background: this study has been undertaken to find out the possible radioprotective potential of the alstonia scholaris extract (ase). materials and methods: for experimental study, healthy swiss albino male mice were selected from an inbred colony and divided in four groups. group i (normal) did not receive any treatment. group ii was orally supplemented ase once daily at the dose of 100 mg/ k...

objective: this study was designed to investigate the antinociceptive effect of curcumin in diabetic rats by using the formalin and hot tail immersion tests. methods: wistar rats were divided into the following six groups:  control; curcumin-treated control (50 mg/kg); diabetic; sodium salicylate (ss)-treated diabetic; and two curcumin-treated diabetic groups (10 and 50 mg/kg). curcumin was ad...

Antioxidant capabilities of scoparone, the component of Artemisia scoparia and other medicinal plants, against lipid peroxidation induced by ultraviolet radiation or Fenton reaction have been analyzed. Lipid peroxidation was monitored by measuring the absorption spectra of the conjugated dienes and quantified by the Klein oxidation index. Obtained results imply that scoparone is a very efficien...

Studies were carried out to determine the actions of and interactions between ascorbate, NADPH, Fe2+, and Fe3+ on lipid peroxidation in adrenal and testicular microsomes. Ascorbate-induced malonaldehyde production was maximal in adrenal and testicular microsomes at an ascorbate concentration of 1 X 10(-4)M. Fe2+, at levels between 10(-6) and 10(-3)M, produced concentration-dependent increases i...

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 malondialdehyde, 4-hydroxy-2-nonenal, reduced glutathione and nitric oxide con...

The goal of this study was to test the hypothesis that antioxidant estrogens, by a mechanism independent of the estrogen receptor, protect phospholipids residing in the plasma membrane of vascular smooth muscle cells from peroxidation and peroxidation-induced cell growth and migration. Peroxidation of membrane phospholipids was assessed by HPLC analysis of phospholipids extracted from rat aorti...

The present study deals with exploration of lipid peroxidation induction capacity of flutamide, an anticancer drug, and in vitro evaluation of water extract of Spirulina platensis as a suppressor of flutamide-induced lipid peroxidation. Goat liver homogenate has been used as the lipid source. This evaluation was done by measuring the malondialdehyde and reduced glutathione content of the tissue...

We analyzed the protective effect of garlic oil on hepatic and blood lipid peroxidation and the antioxidant status during buccal pouch carcinogenesis induced by 7,12dimethylbenz[a]anthracene (DMBA) in male Syrian hamsters. Enhanced lipid peroxidation in the liver and blood of tumor-bearing animals was accompanied by a significant decrease in antioxidant levels. Topical application of garlic oil...

Lipid peroxidation can be described generally as a process under which oxidants such as free radicals attack lipids containing carbon-carbon double bond(s), especially polyunsaturated fatty acids (PUFAs). Over the last four decades, an extensive body of literature regarding lipid peroxidation has shown its important role in cell biology and human health. Since the early 1970s, the total publish...

The effect of various fatty acids on lipid peroxidation of liver microsomes induced by different methods in vitro was studied using oxygen uptake and malonaldehyde (MDA) production. It was observed that fatty acids with a single double bond are effective inhibitors of peroxidation. Stereo and positional isomers of oleic acid were equally effective as oleic acid. There was an absolute requiremen...
