We examined the protective effect of Brazilian propolis against liver damage with cholestasis in rats treated with α-naphthylisothiocyanate (ANIT) in comparison with that of vitamin E (VE). Rats orally received Brazilian propolis ethanol extract (BPEE) (25, 50, or 100 mg/kg), VE (250 mg/kg) or vehicle at 12 h after intraperitoneal injection of ANIT (75 mg/kg) and were killed 24 h after the inje...

This experiment was carried out to determine the effects of putrescine and methyl jasmonate on lipid peroxidation and altering the peroxide hydrogen of peel and pulp of Valencia orange fruit. Orange fruits were treated with 0 (control), 2.5 and 5 mM putrescine, and 0 (control), 10 and 20 µM methyl jasmonate, then stored at 5±1 °C, 85-90% relative humidity for four months. Oranges treated with 5...

Abstract Cystoseira mediterranea (Sauv.) extract was tested for its ability to restore barley ( Hordeum vulgare ) growth under salt stress (350 mM NaCl), shoot growth; membrane integrity; lipid peroxidation and hydrogen peroxide determination were performed. In normal conditions, the obtained data revealed of stimulate most parameters. However, it showed significant effect on parameters (plant ...

To directly examine the role of hydrogen peroxide in the killing of bacteria after ingestion by granulocytes, we have studied some of the events of phagocytosis of a mutant strain of pneumococci which is relatively deficient in peroxide production. The hydrogen peroxide-deficient pneumococci and the otherwise identical wild type were grown with [(14)C]arachidonic and [(3)H]palmitic acid labels ...

The leaves or seeds powder of fenugreek (Trigonella foenum-graecum) were orally administered in the diet to hypercholesterolemic male rats for 8 weeks to test their effect on lipid profile, antioxidants enzymes and lipid peroxide. Twenty four male rats weighing 150-170 gm were divided into four groups. The first group is untreated (control group), fed basal diet, the second group, fed on 2% cho...

OBJECTIVE Oxidative stress or free radical activity may contribute to the pathophysiology of atherosclerosis and other chronic diseases associated with aging. Because psychosocial stress has been shown to increase oxidative stress, we conducted an exploratory study to investigate the effects of stress reduction with the Transcendental Meditation program on serum lipid peroxide levels in elderly...

Hydrogen peroxide is a commonly used oxidizing agent with a variety of uses depending on its concentration. Ingestion of hydrogen peroxide is not an uncommon source of poisoning, and results in morbidity through three main mechanisms: direct caustic injury, oxygen gas formation and lipid peroxidation. A case of a 39-year-old man who inadvertently ingested 250 mL of unlabelled 35% hydrogen perox...
