the aim of this study was to investigate the effects of administering antioxidants, including vitamin c and chitosan on oxidative stress markers in muscle as edible tissues of cyprinus carpio exposed to cadmium chloride. in this experiment, by exposing to 0.2 mg/l cadmium chloride for 21 days, fish were fed a normal diet, diet containing chitosan (1000 mg/kg diet), vitamin c (1000 mg/kg diet) o...

plant tissue culture technique could provide sterile and controllable condition in order to assay direct effect of different compounds on plant growth accurately. in this study, the effects of aqueous extracts prepared from roots and shoots of goosefoot (chenopodium album l.), redroot pigweed (amaranthus retroflexus l.), fennel (foeniculum vulgare), and wormwood (artemisia absinthium l.) were e...

germination is one of the most effective processes to improve the quality of legumes. vitamins and some other compounds that might be considered beneficial as antioxidants, often change dramatically during the course of germination. antioxidants might be defined as compounds which are capable of preventing, delaying or retarding the development of rancidity or other flavor deterioration in food...

the antibacterial and antioxidant activities of methanol and acetone extracts of three marine algae, including hypnea hamulosa, gracilaria corticata and enteromorpha intestinalis wereinvestigated.antioxidant activities were determined by means of total antioxidant capacity, total phenolic compounds, dpph radical scavenging activity and ferric reducing antioxidant power. antibacterial activity w...

background: cancer has the highest disease-related mortality rate in iran. reduced activity of paraoxonase reported in patients with cancer may be due to a reduction in its antioxidant properties and a subsequent increased risk of developing cancer. we aimed to assess antioxidant and oxidative status in patients with cancer through measuring the activity of pon1 as an antioxidant enzyme and det...

Medicinal plants have attracted global attention due to their high levels of antioxidant components for prohibiting or improving various diseases including brain and memory disorders. This study was designed to investigate if the antioxidant effect of Sidr (Zizyphusspina-christi) extract can help to improve the scopolamine induced impairment of memory in Wistar rats. Animals were randomly...

six hundred 1-d-old male broilers (ross 308) were assigned to four experimental groups; each was composed of 5 floor pen replications of 30 birds including control (no enalapril), 15, 30 and 60 ppm enalapril in the drinking water. from d 21 to 49, all the chicks were exposed to low ambient temperature to induce ascites. mortalities were inspected to determine the cause of death and diagnose of ...

Background and objectives: The Mullein genus is the largest genus of Scrophulariaceae family which has extensive natural habitat in southwest of Iran. Mullein contains compounds such as phenolic compounds, mucilage, saponins and anthocyanin. The aim of this study was to evaluate the total flavonoid content and antioxidant activity of mullein ecotypes in Iran. Methods: <...

the present study was carried out to evaluate the antioxidant and free radical scavenging activity of methanolic extract of ervatamia coronaria leaves (apocynaceae) in various systems. dpph radical, superoxide anion radical, nitric oxide radical and hydroxyl radical scavenging assays were carried out to evaluate the antioxidant potential of the extract. the antioxidant activity of methanolic ex...
