In order to gain insight into the antioxidant effect of cinnamon (Cinnamomum verum; Lauraceae) and cardamom (Amomum subulatum; Zingiberaceae) hepatic and cardiac antioxidant enzymes, glutathione (GSH) content and lipid conjugated dienes were studied in rats fed high fat diet along with cinnamon or cardamom. The antioxidant enzyme activities were found to be significantly enhanced whereas GSH co...

In the present study, the effect of long-term salt stress (NaCl with 0, 0.1, 0.4 and 0.7 MPa)-temperature (25±2 oC and 35±2 oC) interaction on some antioxidant enzyme activities (ascorbate peroxidase, glutathione reductase and peroxidase) in six soybean cultivars (Glycine max L. Merr.) was investigated. The leaves of twenty-three-day old plants were used for the analysis of enzyme activities. S...

In the present study, the effect of seed priming with magnetic field (MF; 45, 90, 200 and 250mT for 5, 10, 20 and 30 min) was evaluated in 60-day-old Hyssopus officinalis plants grownunder 8 days irrigation intervals. The assessments were consisted of biomass, membranestability, photosynthetic pigments concentrations, polyphenols content, antioxidant enzymesactivities an...

Background: Withania somnifera L. Dunal, (Ashwagandha) belongs to the family Solanaceae and is known as ‘Indian ginseng’ in the traditional system of medicine. Objectives: In the present investigation, comparative analysis was carried out between two different ecotypes of W. somnifera related to total soluble protein and antioxidant enzyme activity [catalase (CAT), s...

Phytohormones such as auxin are known to be involved in alleviating the detrimental effects of salinity by modulating the activity of enzymatic antioxidants and improving antioxidant system, which help in sustaining plant growth. The present study envisaged revealing the role of exogenous application of indole-3-acetic acid (IAA) in improving defense mechanisms in two genotypes (FL485 and IR29,...

 The effect of sodium silicate (Si) and potassium (K) were investigated on the major antioxidant enzyme activities in two different grapevine cultivars (Vitis vinifera L., cvs Yezandai and Malinger Ramfi) under drought stress. The traits included superoxide dismutase (SOD, EC 1.15.1.1), catalase (CAT, EC 1.11.1.6), peroxidase (POD, EC 1.11.1.7), guaiacol peroxidase (GPX, EC 1.11.1.7), ascorbate...

Abstract Objective: Electro-magnetic radiation (EMR) is emitted from mobile phones. Various researches have shown relationships between mobile phone EMR exposure to cancer and neurologic damages. This study aims to investigate the effects of mobile phone EMR on brain antioxidant enzyme activity and the learning process. Methods: Rat pups and their dames were exposed to EMR for 3 h per day from ...

The aim of this study was to investigate the effects of IcarisideII(ICAII) on the prevention of streptozotocin (STZ) induced spermatogenic dysfunction. Forty male Sprague-Dawley rats received intraperitoneal injection of STZ (55 mg/kg) and were equally randomized to gavage feeding of vehicle (the vehicle group) or ICAII (0.5, 1.5 or 4.5 mg/kg/day, respectively). Ten normal rats received vehicle...

Cisplatin (CP) is an anticancer drug that enhances renal generation of reactive oxygen metabolites, lipid peroxidation and inflammation. This study examined the effect of hydrogen sulfide on lipid peroxidation content, tissue antioxidant enzyme activities and tumor necrosis factor (TNF-α) in cisplatin nephrotoxic rats. Thirty male Sprague-Dawley rats were divided into three groups of 10 rats in...
