Background: Helicobacter pylori infection and non-steroidal anti-inflammatory drugs are two major causes of gastric ulceration but interactions between H pylori and these drugs in gastric mucosal injury are unclear. Aims: We studied the influence of experimental H pylori infection on gastric mucosal injury induced by aspirin. Subjects: Male Mongolian gerbils free of specific pathogens were used...

effects of catechin for preventing black spots forming in whiteleg shrimp (litopenaeus vannamei) were evaluated. for processing whole shrimp, catechin was used at a concentration of 0.2 and 0.3 % for 15 minutes. sodium metabisulfite was used at a concentration of 3 % for 10 minutes as control samples. without antioxidant shrimp were used as control samples too. treatments quality was evaluated ...

The metabolism of ethanol gives rise to the generation of excess amounts of reactive oxygen species and is also associated with immune dysfunction. We examined the efficacy of resveratrol and vitamin E on the immunomodulatory activity and vascular function in mice with liver abnormalities induced by chronic ethanol consumption by measuring the protein, liver-specific transaminase enzymes, antio...

Problem statement: The present study was carried out to examine the effectiveness of Camel’s milk in alleviating aluminum chloride (AlCl3)-induced oxidative stress and lipid peroxidation in rat testes. Approach: White albino male rats (230-250 g) were divided into three groups of 10 rats: A control group, treated with normal saline and two experimental groups, the AlCl3 treated group and the Ca...

Ethanol metabolites may directly or indirectly induce oxidative stress as a result of disturbed balance between proand antioxidative processes. An indirect effect of ethanol on the generation of oxidative stress is associated with the attenuation of intracellular defensive enzymatic antioxidants, e.g. gluthatione peroxidase, catalase, superoxide dismutase as well as waterand/or fat-soluble low-...

The study assessed the effect of some highly active antiretroviral therapies (HAART), used in the management of HIV/AIDS in Cameroon, on oxidative stress markers such as malondialdehyde (as TBARs), albumin, protein carbonyl content and protein sulfhydryls groups. 85 HIV positive patients (34.8 +/- 9.3 years) were on three different highly active antiretroviral therapies (HAART patients). 65 HIV...

The extract of Mangifera indica L. (Vimang) is able to prevent iron mediated mitochondrial damage by means of oxidation of reduced transition metals required for the production of superoxide and hydroxyl radicals and direct free radical scavenging activity. In this study we report for the first time the iron-complexing ability of Vimang as a primary mechanism for protection of rat liver mitocho...

this study was conducted to determine the effect of dietary turmeric rhizome powder (trp) as a natural antioxidant, and soybean oil, canola oil and tallow on lipid metabolism, blood metabolites, immune system, and antioxidant status of broiler chickens before (bhs, 28 d) and after exposure to heat stress (ahs, 42 d). seven hundred and ninety two d-old male arian broilers were randomly allotted ...

Copper alloy surfaces are passive antimicrobial sanitizing agents that kill bacteria, fungi, and some viruses. Studies of the mechanism of contact killing in Escherichia coli implicate the membrane as the target, yet the specific component and underlying biochemistry remain unknown. This study explores the hypothesis that nonenzymatic peroxidation of membrane phospholipids is responsible for co...

Oxidant stress is one of the factors proposed to be responsible for damaged erythrocytes observed during and after exercise. The impact of exertional oxidant stress after acute exhaustive treadmill running on erythrocyte damage was investigated in sedentary (Sed) and exercise-trained (ET) rats treated with or without antioxidant vitamins C and E. Exhaustive exercise led to statistically signifi...
