a greenhouse experiment was performed in the framework of a completely randomized design and a factorial arrangement to evaluate the effect of arbuscular mycorrhizal fungi (amf) on growth and on root antioxidant enzyme changes of two citrus rootstocks (sour orange and rough lemon). the experimental factors were: mycorrhizal treatments at two levels (inoculation with glomus mosseae vs. control) ...

this study was conducted to investigate the effect of different levels of savory (satureja hortensis) powder and its essential oil on performance and antioxidant status of broiler chickens under heat stress (34±2 ˚c for 8 hours per day). a total of 336 one-day-old male broiler chicks (ross-308) were divided into 6 treatments and 4 replications (14 birds per replicate). experimental diets were a...

a hydroponics study was carried out in order to understand the behavior of antioxidant enzymes, soluble protein content and its effect on cell death in different old leaves of durum wheat. two month after planting, the different old leaves were sampled and the activity of super oxide dismutase (sod), catalase, ascorbat peroxidase and guaiacol peroxidase were measured. furthermore, the rate of c...

Aqueous leaf extract of L. speciosa (banaba) effectively decreased the blood glucose in streptozotocin-induced diabetic mice after 15th day of banaba exposure. Further, banaba leaf extract have the potential to inhibit lipid peroxidation and effectively intercept/neutralize reactive oxygen species such as super oxide, H2O2 and NO based free radicals. The aqueous banaba leaf extract (150 mg/kg b...

introduction: considering the prevalence of epilepsy and the failure of available treatments for many epileptic patients, finding more effective drugs in the treatment of epilepsy seems necessary. oxidative stress has a special role in the pathogenesis of epileptic syndrome. therefore, in the present study, we have examined the anti-epileptic and anti-oxidant properties of the ferula assa foeti...

Approximately 2% of amyotrophic lateral sclerosis (ALS) cases are caused by mutations in the super oxide dismutase 1 (SOD1) gene and transgenic mice for these mutations recapitulate many features of this devastating neurodegenerative disease. Here we show that the amount of anandamide (AEA) and 2-arachidonoylglycerol (2-AG), two endocannabinoids that have neuroprotective properties, increase in...

The aim of the present study was to examine whether endocannabinoids cause PPARγ-mediated vascular actions. Functional vascular studies were carried out in rat aortae. Anandamide and N-arachidonoyl-dopamine (NADA), but not palmitoylethanolamide, caused significant vasorelaxation over time (2 hours). Vasorelaxation to NADA, but not anandamide, was inhibited by CB(1) receptor antagonism (AM251, 1...

this study was conducted to evaluate changes in antioxidants, free proline, relative water content and determination of root colonization of four commercial wheat (triticum aestivum l.) cultivars (azar2, darab2, shiraz, and falat) inoculated with the fungus glomus intraradices, under four water regimes of 100, 75, 50, and 25% of field capacity in the year 2010 at the school of agriculture, shir...

Background: This study was carried out to assess the effects of MnTBAP, a cell permeable antioxidant, on motility, membrane integrity, capacitation status and in vitro fertilization ability of frozen-thawed ram semen. Materials and Methods: Fresh semen ejaculates were collected with artificial vagina from five rams, mixed and divided into five equal fractions, and diluted (1:20 v/v) with commer...
