patterns of superoxide dismutase, catalase and peroxidase antioxidant isozymes in seedlings of white beans under salt stress

peroxidase, superoxide dismutase and catalase activities of the pistacia khinjuk seedlings under drought stress

the aims of this study were to assess the effects of drought stress on peroxidase (pod), superoxide dismutase (sod) and catalase (cat) activities as well as free proline content and growth parameters of pistacia khinjuk seedlings under drought stress. therefore, the one-year seedlings of pistacia khinjuk subjected to water stress (25%, 50%, 75%, and 100% field capacity) for 8 months in greenhou...

Action of hypochlorous acid on the antioxidant protective enzymes superoxide dismutase, catalase and glutathione peroxidase.

The neutrophil enzyme myeloperoxidase generates hypochlorous acid (HOCl) at sites of inflammation. Glutathione peroxidase is very quickly inactivated by low concentration of HOCl. Inactivation of catalase is also rapid, but requires higher HOCl concentrations and the haem appears to be degraded. Inactivation of bovine CuZn superoxide dismutase is slower. Hence superoxide dismutase should not be...

Antioxidant Isozymes Activities in Potato Plants (Solanum tuberosum L.) Under Salt Stress

Antioxidant Effect of Lycopersicum esculentum on Plasma Superoxide Dismutase, Catalase and Malondialdehyde in Rat Espoused with Lead Acetate

Background: Lead, an example of heavy metals, has, for decades, being known for its adverse effects on various body organs and systems such that their functions are compromised. Objective: In the present study, the ability of Lycopersicum esculentum on decrease toxic effects of lead acetate on plasma superoxide dismutase, catalase and malondialdehyde in Rat. Lead to adversely affect the Liver ...

CuZn-superoxide dismutase, Mn-superoxide dismutase, catalase and glutathione peroxidase in pancreatic islets and other tissues in the mouse.

Exogenous superoxide dismutase, catalase and scavengers of the hydroxyl radical protect pancreatic-islet cells against the toxic actions of alloxan in vitro [Grankvist et al. (1979) Biochem. J. 182, 17--25]. To test whether the extraordinary sensitivity of islet cells to alloxan is due to a deficiency of endogenous enzymes protecting against oxygen-reduction products, we assayed CuZn-superoxide...

گروه بندی ارقام مختلف گندم از نظر تحمل شوری بر اساس برخی شاخص‌های بیوشیمایی و فیزیولوژیک

In attention to wheat importance in human nutrition and  its production limitations due to salt stress, this study was conducted to evaluate and grouping 52 different wheat varieties for activities of antioxidant enzymes. Seedlings in 4-5 leaf stage, which were grown in aeroponic way, were exposed to salt stress using 200 mM NaCl for 10 days. After that, activities of enzymes of catalase, gluta...
