conclusions the administration of 75 mg/kg/day cinnamon significantly increased the sperm population, motility and viability, which supports the theory that in mammalians, cinnamon has a beneficial effect on spermatogenesis. results sperm quality parameters, total serum testosterone, sod, cat, and gpx levels were significantly increased in the cinnamon group in comparison to controls (p < 0.05)...

conclusions consumption of ole after tumor transplantation reduced the tumor growth. on the other hand, owing to its highly-packed polyphenols, catalase and superoxide dismutase activities in tumor tissue were increased. results treatment with 150 and 225 mg/kg/day of ole reduced the tumor volume and weight (p < 0.05) compared to the first group significantly. it also increased the cat activity...

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...

cadmium is considered as a common residue in water and sediments which could readily enter aquatic organisms. the aim of this study was to evaluate the time- and concentration-dependent changes in antioxidant enzymes (sod and cat) activities as well as concentration of mda as a bi- product of lipid peroxidation in the liver of persian sturgeon, acipenser persicus , following cdcl 2 exposure at ...

Survival of rats exposed to 100% oxygen was increased from 69.5 +/- 1.5 to 118.1 +/- 9.9 h (mean +/- SEM, P less than 0.05) when liposomes containing catalase and superoxide dismutase were injected intravenously before and during exposure. The increased survival time in 100% oxygen was also associated with significantly less fluid in the pleural cavity. Rats injected with catalase- and superoxi...

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...

The distribution of catalase and superoxide dismutase has been examined in various micro-organisms. Strict anaerobes exhibited no superoxide dismutase and, generally, no catalase activity. All aerobic organisms containing cytochrome systems were found to contain both superoxide dismutase and catalase. Aerotolerant anaerobes, which survive exposure to air and metabolize oxygen to a limited exten...

trichosanthes kirilowii, an important economic plant in china, is sensitive to chilling. to investigate the effect of abscisic acid (aba) treatment on the chilling tolerance of trichosanthes kirilowii maxim, different concentrations of aba were sprayed on trichosanthes kirilowii leaves and the resulting catalase (cat) and superoxide dismutase (sod) activities and the malondialdehyde (mda) conte...

selenium is an essential element for humans, therefore, adding it to plants is convenient for biofortification. thus, the aim of this work was to analyze experimentally the ability of sodium selenite to increase the concentration of se and modify the antioxidant activity in tomato plants. we used plants of the toro hybrid variety and applied three treatments: 0, 2 and 5 mg l-1 of selenium as so...
