Alpha amanitin and phalloidin are powerful hepatotoxins that belong to the main classes of toxins namely, amatoxins and phallotoxins, isolated from the deadly poisonous mushroom Amanita phalloides. It is well known that disruptions of antioxidant enzyme defense that include superoxide dismutase (SOD), catalase, glutathione peroxidase lead to generation of reactive oxygen species, followed by in...

The mechanism of protective effects of Liv-52, a multiherbal hepatoprotective drug, on ethanol induced hepatic damage has been investigated. The results indicate that Liv-52 treatment prevents ethanol induced increase in the activity of the enzyme gamma-glutamyl transpeptidase. Concomitantly there was also a decrease in ethanol accentuated lipid peroxidation in liver following Liv-52 treatment....

Previous studies demonstrated a significant reduction of ultimate infarct size in the canine heart by the combined administration of superoxide dismutase plus catalase. This study was performed to assess the independent effects of each enzyme on ultimate infarct size due to ischemia/reperfusion. Dogs received 2-hour infusions of superoxide dismutase, catalase, or albumin (controls) via the left...

Arbuscular mycorrhizal fungi (AMF) have been used to enhance the plant growth and yield maintain good health fertility that contributes great extents a sustainable product. The study was undertaken identify responses of antioxidant enzymes activities in tomato (Solanum lycopersicum L.Var PMK 1 Vaibhav) inoculated with AM fungi. increased enzyme such as Superoxide dismutase (SOD) Catalase (CAT) ...

The activity of antioxidant enzymes, copper-zinc superoxide dismutase (CuZnSOD), manganese superoxide dismutase (MnSOD) and catalase (CAT), as well as that of the mitochondrial FAD-dependent alpha-glycerophosphate dehydrogenase (alpha-GPD) in the rat interscapular brown adipose tissue (IBAT) were studied after the treatment with methimazole (MMI) for three weeks or with iopanoic acid (IOP) for ...

Formaldehyde is the illegal chemical substance used for food preservation in fish and vegetable. It can promote carcinogenesis. Superoxide dismutases are the important antioxidative enzymes that catalyze the dismutation of superoxide anion into oxygen and hydrogen peroxide. The resultant level of oxidative stress in formaldehyde-treated lymphocytes was investigated. The formaldehyde concentrati...

The reconstitution of Cu,Zn-superoxide dismutase from the copper-free protein by the Cu(I)*GSH complex was monitored by: (a) EPR and optical spectroscopy upon reoxidation of the enzyme-bound copper; (6) NMR spectroscopy following the broadening of the resonances of the Cu(I)*GSH complex after addition of Cu-free,Zn-superoxide dismutase; and (c) NMR spectroscopy of the Cu-free,Co(II) enzyme foll...

Background: This study examined the effect of grape seed proanthocyanidin extract (GSPE) on lipid peroxidation content and activity of tissue antioxidant enzymes, including catalase, superoxide dismutase and glutathione peroxidase in diabetic rats. Methods: Thirty male rats were divided into three groups of 10 rats each: control, diabetic and diabetic groups that received 500 mg/kg GSPE for 6 w...
