Commiphora mukul commonly known as Guggul is one of the oldest and commonly consumed herb for promoting heart and vascular health. Present study was undertaken to evaluate cardioprotective potential of Commiphora mukul against isoprenaline-induced myocardial necrosis in rats. Wistar albino rats were divided into three main groups: sham (saline only), isoprenaline control (saline and isoprenalin...
Raspberry waste, obtained from two cultivars, Meeker (ERM) and Willamette (ERW) was subjected to evaluation antioxidants and antitumour activities as a potential source of phenolics. Some phenolic acids and flavonoids were identified and quantified by HPLC. Antioxidant activity was tested by measuring ability to scavenge DPPH• and •OH by ESR spectroscopy. IC50DPPH• varied from 0.67 for ERM to 0...
Aging is related to the accumulation of reactive oxygen species (ROS)-mediated oxidative damage. Considering the heterogeneity of age-related changes and the involvement of muscles in different functions, we compared the aging process in different functional muscles. We studied age-related changes in rectus abdominis (RA) and vastus lateralis (VL) in subjects of different age (18-48- and 66-90-...
OBJECTIVE The aim of this study was to determine the possible association of oxidant/antioxidant status and recurrent aphthous stomatitis (RAS). STUDY DESIGN The study consisted of thirty-one patients with RAS and thirty-two healthy controls from whom saliva and blood samples were collected. Superoxide dismutase (SOD), glutathione peroxidase (GSHPx) and catalase (CAT) were measured in erythro...
introduction: the fate of xenobiotics that is present, increasing day by day. the increasing fates altered or inhibit the metabolic activities like detoxification and biotransformation. methods: the present study highlights this slow biotransformation and detoxification on the basis of specific enzymes which have a say in assessment of mercuric chloride toxicity and modulation by panax ginseng ...
The objective of this study was to determine if bupivacaine has any effects on the antioxidant defence system and in lipid peroxidation as thiobarbituric acid substance (TBARS) of spinal fluid. The experiment was carried out on 15 male clinically healthy, 3-4 years old, male Tuj ram weighing an average 56±5 kg. Eight ml of 0.5% bupivacaine was used for the induction of spinal anesthesia (SA). T...
The protective effect of sesamin (SES) from sesame meal on NIT-1 pancreatic β-cells damaged by streptozotocin (STZ) in vitro was investigated. The cell viability, insulin secretion, the activity of superoxide dismutase(SOD), glutathione peroxidase (GSHpx) and the content of reduced glutathione (GSH) increased significantly when incubated with SES (400, 200 µg mL-1). The content of malondialdehy...
Antioxidant enzymatic pathways form a critical network that detoxifies ROS in response to myocardial stress or injury. Genetic alteration of the expression levels of individual enzymes has yielded mixed results with regard to attenuating in vivo myocardial ischemia-reperfusion injury, an extreme oxidative stress. We hypothesized that overexpression of an antioxidant network (AON) composed of SO...
The BIO 14.6 cardiomyopathic Syrian hamster is a well-known animal model of congestive cardiomyopathy. To evaluate the role of free radicals and antioxidant protection in the pathogenesis of cardiomyopathy in this animal, we studied the concentration of heart mitochondrial free radicals, the activities of glutathione peroxidase (GSHPx) and superoxide dismutase (SOD), and the effect of alpha-toc...
Malondialdehyde (MDA), Cu,Zn-superoxide dismutase (Cu,Zn-SOD) and selenium-dependent glutathione peroxidase (GSPHx) are currently considered to be basic markers of oxidative stress. MDA is one of the end-products of the peroxidation of membrane lipids, whereas enzymes Cu,Zn-SOD and GSHPx belong to the natural antioxidants. The role of oxygen free radicals in the pathogenesis of many diseases is...
