Geraniol attenuates hydrogen peroxide-induced liver fatty acid alterations in male rats.

Background: Hydrogen peroxide (HO) is an oxidant agent and this molecule naturally occurs in the body as a product of aerobic metabolism. Geraniol is a plant-derived natural antioxidant. The aim of this study was to determine the role of geraniol on hepatic fatty acids alterations following HO-induced oxidative stress in male rats.

The investigation of some bioactive compounds and antioxidant properties of hawthorn (Crataegus monogyna subsp. monogyna Jacq).

Aim: The antioxidant and pharmacological effects of hawthorn have mainly been attributed to the polyphenolic contents. The aim of this research is to determine some bioactive compounds and antioxidant properties of hawthorn aqueous and ethanol extracts of leaves, flowers, and ripened fruits.

Materials And Methods: For this purpose, antioxidant activities of extracts were assessed on DPPH•, ABTS•+, superoxide scavenging, reducing power and ferrous metal chelating activity assays and phenolic content of extracts was determined by Folin-Cioacalteu's reagent.

Total phenolic contents and free-radical scavenging activities of grape (Vitis vinifera L.) and grape products.

Grape is one of the world's largest fruit crops, with an approximate annual production of 58 million metric tons, and it is well known that the grape skins, seeds and stems, waste products generated during wine and grape juice processing, are rich sources of polyphenols. It contains flavonoids, phenolic acids and stilbenes. In this study, we tried to determine antioxidant properties and phenolic contents of grape and grape products (fresh fruit, seed, dried fruit, molasses, pestil, vinegar) of ethanol and water extracts.

Effects of intraperitoneally administered ubiquinone on the level of total lipid and fatty acids in rat liver.

The purpose of the present study was to evaluate the effect of ubiquinone (coenzyme Q-10) on total lipid and fatty acid composition of liver tissues in rats. Twenty male wistar rats were randomly divided into two groups. The first group was used as a control.

A combination of alpha-tocopherol, vitamin C and N-acetyl cysteine increases unsaturated fatty acid levels in hydrogen peroxide-induced Candida tropicalis (ATCC 13803).

This research was aimed at evaluating the antioxidant effects of combinations of alpha lipoic acid (LA), vitamin C (VC), N-acetyl cysteine (NAC) and alpha-tocopherol (TOC) on lipid level and fatty acid composition of C. tropicalis (ATCC 13803) against hydrogen peroxide toxicity. According to the experimental results, the cell density of C.

Effects of certain micronutrients and melatonin on plasma lipid, lipid peroxidation, and homocysteine levels in rats.

Background: Numerous studies suggest an association between high intake of antioxidant vitamins and fish oil and reduced risk of coronary heart disease. Hyperhomocysteinemia has also been identified as an independent risk factor for arteriosclerosis. In this paper, we aimed to evaluate the effects of vitamin E, vitamin C, vitamin C 6 palmitate (VC6P), lipoic acid, fish oil, and melatonin supplementation on lipid peroxidation, plasma lipid, and homocysteine (Hcy) levels in rats.

Effects of intraperitoneally administered lipoic acid, vitamin E, and linalool on the level of total lipid and fatty acids in guinea pig brain with oxidative stress induced by H2O2.

The aim of our study was to investigate the protective effects of intraperitoneally-administrated vitamin E, dlalpha lipoic acid, and linalool on the level of total lipid and fatty acid in guinea pig brains with oxidative stress that was induced by H2O2. The total brain lipid content in the H2O2 group decreased when compared to the H2O2 + vitamin E (p<0.05), H2O2+ linalool (p<0.

Influence of vitamin E on the levels of fatty acids and MDA in some tissues of diabetic rats.

This study was performed to determine whether vitamin E supplementation in streptozotocin-induced diabetic rats treated with insulin could affect the levels of fatty acid composition and malondialdehyde (MDA) of brain, liver and muscle tissues. Thirty Wistar albino rats were used during the experiments. They were randomly divided into three groups, each consisting of six individuals.
