Lead and Zinc Influence on Antioxidant Enzyme Activity and Malondialdehyde Concentrations
نویسندگان
چکیده
The influence of zinc on the activity of antioxidant enzymes in the blood of rats intoxicated with lead was studied. Exposure to lead at the concentration of 500 mg/dm for 6 weeks caused a decrease in the activities of SOD, GSH-PX and GR as well as an increase in MDA concentrations in the serum. Zinc at the concentration of 60 mg/dm administered for a period of 2 weeks after exposure to cadmium reduced the effects of toxic action of lead leading to a normalization of the activities of SOD and GR in the blood as well as MDA concentration in the serum.

The increase of environmental pollutants especially heavy metals derives from human industrial communities. Zinc is one of the natural elements that exist in biotic environment, plants body, and animals in different forms. Zinc has toxic and lethal effects in high concentrations on plants. Also some plants are introduced as accumulators of this element. Therefore, an investigation was carried o...
متن کاملSecondary Metabolite Contents and Antioxidant Enzyme Activities of Cichorium intybus Hairy Roots in Response to Zinc
Hairy root systems are formed by transforming plant tissues with the “natural genetic engineer” Agrobacterium rhizogenes. In most plants such as Cichorium intybus L., hairy root cultures have proven to be an efficient system for secondary metabolites production. The effect of Zinc (ZnSO4), a heavy metal, was investigated at different concentrations (0, 1, 5 and 10 mM) on some secondary metaboli...

This study evaluated the effect of the intermittent light program on serum and brain melatonin concentrations, antioxidant enzyme activities, and homocysteine concentration in broiler chickens. A total of 60 one-day-old broiler chickens (Cobb 500) were distributed in three light-proof controlled rooms (20 chicks per room). All birds were reared in continuous light until 3 days of age. Then, chi...

Introduction: Copper and zinc play a key role in oxidative reactions and in vivo studies have shown their different effects. In this study we examined the influence of exposure to copper and zinc on catalase and superoxide dismutase (SOD) activities in erythrocytes, total serum antioxidant capacity and malondiadehyde (MDA) production of copper industry workers. Methods: In the present study...
