the present study investigated the effects of e. coli lipopolysaccharide (lps) induced mastitis model in rat on the activity of antioxidant enzyme systems. to achieve this purpose, e. coli lps were infused into the mammary gland of 12 rats 72 hr postpartum and compared with 12 rats in control group infused intramammary placebo sterile pyrogene – free, physiological saline. the antioxidant activ...

Hypercholesterolemia is one of the leading causes cardiovascular disease. Probiotics can help to improve high blood lipid levels in hypercholesterolemia patients. Lactobacillus paracasei has been reported have beneficial effects several subjects; however, there a lack studies on Thai hypercholesterolemic subjects. Thus, this study was conducted order investigate effect L. HII01 cholesterol, oxi...

Immune defense involves inflammatory reactions in which immune cells produce reactive oxygen species (ROS) to fight pathogens. ROS may however cause damage to the host if they are not balanced by antioxidant defenses. Therefore, one should expect individuals undergoing an immune reaction to use antioxidants to prevent oxidative stress. Antioxidants are vital compounds that provide important pro...

nigella sativa (ns) ( ranunculaceae ) used as a protective and therapeutic traditional medicine. this study evaluates the effect of ns on inflammation-induced myocardial fibrosis, serum and tissue inflammatory markers, and oxidative stress status in male rats. fifty male wistar rats were divided into five groups: (1) control; (2) lipopolysaccharide (lps), 1 mg/kg/day; (3) lps + ns (hydroalcohol...

background : methamphetamine (ma) is an illegal amphetamine-like which stimulate the central nervous system. in recent years, ma has been widely abused worldwide. previous studies have suggested that oxidative stress (os) plays an important role in ma-induced toxicity. from this view, antioxidant therapy could be considered as a potential drug therapy in ma abusers. therefore, the objective of ...

objective(s): buthionine sulfoximine (bso) inhibits synthesis of glutathione as the main intracellular antioxidant. the aim of the present study is to investigate the effect of bso-induced oxidative stress on histological structure of testis, testosterone secretion and semen parameters. materials and methods: thirty male balb/c mice were divided into 3 groups. in control group, the mice did not...

objective(s) oxidative stress plays an important role in diabetic nephropathy pathogenesis. rosmarinic acid, a plant phenolic compound, was first used as an antioxidant agent for inhibition of diabetic nephropathy. material and methods forty male rats were uninephrectomized from the left flank.the rats were divided in four groups randomly; group one as control, group two diabetic untreatment, g...

objective(s) nonenzymatic glycosylation (glycation) occurs in many macromolecules in aging and diabetes due to exposure of biomolecules to high level of glucose. glycation can changes function, activities and structure of many biomolecules. considering this important role of transferrin (trf) in iron transport and antioxidant activity in plasma this study was carried out to investigate the effe...

objectives:vagal pathways in gastrointestinal tract are the most important pathways that regulate ischemia/reperfusion (i/r).  gastrointestinal tract is one of the important sources of melatonin production. the aim of this study was to investigate probable protective effect of the interaction between vagus nerve and melatonin after i/r. materials and methods:this study was performed in male rat...

objective(s):to evaluate the effect of graptophyllum pictum on lipid peroxidation and tissue antioxidant enzymes in liver and kidney of gentamicin induced nephrotoxic rats. materials and methods: animals were grouped into 6: group 1 received gum acacia, group 2 received g. pictum ethanol extract (300 mg/kg), group 3 received gentamicin, groups 4, 5, 6 received gentamicin along with g. pictum at...
