Evidence shows that there is a rapid increase in the production of markers of oxidative damage immediately following acute stroke and that endogenous antioxidant defences are rapidly depleted, thus permitting further tissue damage. Several studies point to an antioxidant effect of B-group vitamins and a pro-oxidant effect of elevated plasma tHcy (total homocysteine). In the present study, we as...

Present experiment examined the supplementary effect of a tailor-made supplement to farmers’-based diet in crossbred calves. Male calves (15) were randomly allocated 3 dietary treatments consisting 5 each. The were: Control- cereal straw-based with concentrate mixture as per farmers’ practices; CS (customised supplement)- control additional customised @ 0.25% BW; SD-standard diet. Serum glucose...

BACKGROUND/OBJECTIVES The objective of this study was to measure and/or estimate the total antioxidant capacity of the Korean diet. MATERIALS/METHODS Eighty-one plant foods that were expected to exhibit rather high antioxidant activities were selected from the Korean diet using the Fifth Korean National Health and Nutrition Survey (KNHANES V). These foods were categorized into 11 food groups:...

I read the recent publication on evaluation of iron deficiency anemia via total antioxidant capacity with great interest [1]. It concluded that, “increased oxidative stress may play a role in the pathogenesis of iron deficiency anemia” and that ,“the automated assay is a reliable and easily applied method for measurement of serum total antioxidant capacity in iron deficiency anemia” [1]. There ...

The objective of this article was to review the effects of xenobiotics on total antioxidant capacity (TAC). Measurement of TAC is appropriate for evaluation of the total antioxidant defenses of blood, cells, and different kinds of tissues and organs. TAC is reduced by alcoholism, smoking, and exposure to radiation, herbicides, carbon monoxide, carbon tetrachloride, lead, arsenic, mercury, cadmi...

Objectives Oxidative stress consequent to cigarette smoking may alter the salivary antioxidant defense system and lead to oral cancer. Green tea, with antioxidant properties, interacts with saliva upon entering the mouth. This experimental study explored the preventive effect of green tea on cigarette smoke-induced oxidative damage over 3 weeks. Methods In this clinical trial study sixty volun...

introduction: free radicals are molecules or atoms with single electron that results in reactions thus causing severe damages to the body’s macromolecules. by preventing the formation of free radicals, repairing damages caused by radical’s activities, increasing the excretion of the damaged molecules and minimizing the cellular mutation, the antioxidant defense system contrasts the damages caus...
