The antioxidant enzymes like catalase and superoxide dismutase (SOD) were studied in erythrocytes and lens at various stages of cataractogenesis in albino rats. The rate of peroxidation was measured by assessing the malondiadehyde (MDA) in lens and plasma. The insoluble and soluble protein fractions were measured in lens to study the protein crosslinkings in relation to the above said parameter...
background: spindle trees (euonymus japonica thunb.) growing in an industrial complex area containing pollutants is chronically injured thus need to build up their resistance. antioxidant enzymes and cell membrane stability have been widely used to differentiate stress tolerance. materials and methods: leaves of spindle trees from a clean control area (kijang) and an industrial area (onsan) whe...
this study was conducted in acompletely randomized block design with three replications using three concentrations of 107, 105, and 103cfu/ml of azotobacter isolated from the rhizosphere of karun varieties of barley (az. salentris) and standard az.chrococom along with control (zero concentration of bacteria). the aim of this study was to study the reactions of barley plantin response to inocula...
stinging nettle (urtica dioica l.,) is a medicinal herb commonly used by humans. the role of reactive oxygen metabolites on cancer etiology is known. there are some studies about the antioxidant effects of urtica dioica (ud) on therapy of some cancer types. this study aimed to investigate the effects of ud on antioxidant enzyme activities and mammary gland cancer induced by in rats-n-methyl-n-n...
the present study was designed to investigate the protective effect of ethanol extracts from lindera coreana leaves (lce) on uvb-induced oxidative stress in hacat keratinocytes. the hacat cells were pretreated with lce for 24 h and then exposed to uvb (20 mj/cm2) for 2 h. uvb significantly decreased the cell viability (p<0.05). lce did not exhibit significantly cytotoxic effects and increased t...
objective(s):one cause of cigarette smoking is oxidative stress that may alter the cellular antioxidant defense system, induce apoptosis in lung tissue, inflammation and damage in liver, lung, and kidney. it has been shown that chinese green tea (cgt) (lung chen tea) has higher antioxidant property than black tea. in this paper, we will explore the preventive effect of cgt on cigarette smoke-in...
The present study examined the antioxidant defense of glutamine on plasma and liver antioxidant status in broilers under PHS with respect to changes in the levels of lipid peroxidation marker malondialdehyde (MDA), total antioxidant status (TAS) and the activities of anti peroxidative enzymes [superoxide dismutase (SOD) and glutathione dependent antioxidant enzymes glutathione peroxidase (GPX)]...
BACKGROUND The oxidant stress, expected to increase in obese adults, has an important role in the pathogenesis of many diseases. It results when free radical formation is greatly increased or protective antioxidant mechanisms are compromised. The main objective of this study is to evaluate the antioxidant response to obesity-related stress in healthy children. METHODS A hundred and six health...

conclusions gallic acid and csa combination improved antioxidant capacity and cell membrane integrity more than each one alone. therefore, it can be a therapeutic approach to reduce the i/r injury. background myocardial infarction is one of the important causes of death during old ages. gallic acid as an antioxidant or cyclosporine a (csa) as inhibitor of mitochondrial permeability transition p...
