A method is described for measuring lipid peroxides by means of the color reagent of a commercially available test kit for cholesterol estimation. In principle, this assay makes use of the oxidative capacity of lipid peroxides to convert iodide to iodine, which can be measured photometrically at 365 nm. Calibration curves were obtained using peroxides such as H2O2, t-butyl hydroperoxide, and cu...

Studies of ferriheme cyclooxygenase, using two different assay systems, show that a variety of peroxides can trigger a rapid acceleration of cyclooxygenase activity to produce prostaglandins. Lipid hydroperoxides formed by lipoxygenase were the most potent activators tested, followed by prostaglandin Gz, which was slightly less potent. Peroxides nonspecifically generated during arachidonate aut...

objective(s) recent studies revealed the neuroprotective effects of epigallocatechin gallate (egcg) on a variety of neural injury .the purpose of this study was to determine the effects of egcg on the tissue lipid peroxidation after spinal cord injury (sci). materials and methods rats were randomly divided into four groups of 7 rats each as follows: sham-operated group, trauma group, and egcg-t...

background: sohan is an iranian traditional brittle confection which its ingredients are susceptible to oxidation and microbial contamination during storage. this experimental study was designed to determine the effect of damask rose (rosa damascena mill.) extract on some chemical, microbial, and sensory properties of sohan during storage at 25 °c. methods: the sohan ingredients were mixed, bak...

BACKGROUND The epidemiology of plasma lipid peroxides, which may play a role in atherogenesis, has not been well defined. AIM To study the relationships of plasma lipid peroxides to cardiovascular risk factors in a random population sample. DESIGN Random, age- and sex-stratified population sample. METHODS We studied 739 men and women aged 25-74 years. Lipid peroxides were assayed by the t...

We hypothesize tha t prostacyclin (PG I2) is an anti-atherosclerotic hormone and that atherosclerosis develops when endothelial P G I2 synthetase is inhibited by lipid peroxides. Serum lipid peroxides occur in low-density lipoproteins (LDL). LDL lipid peroxides are elevated in common types of hyperlipoproteinaemias, P G I2 generation is im paired in atherosclerosis, and infusion of synthetic P ...

The effect of curcumin administration in reducing the serum levels of cholesterol and lipid peroxides was studied in ten healthy human volunteers, receiving 500 mg of curcumin per day for 7 days. A significant decrease in the level of serum lipid peroxides (33%), increase in HDL Cholesterol (29%), and a decrease in total serum cholesterol (11.63%) were noted. As curcumin reduced serum lipid per...
