background: diabetes is a major cause of death. oxidative stress mainly caused by hyperglycemia is the primary reason of related complications. omega-3 fatty acids are prescribed in diabetes but the effect on antioxidant defense is controversial. this study investigated effects of omega-3 supplementation on antioxidant enzymes activity in type 2 diabetic patients. methods: a randomized, placebo...

lead (pb) is one of the most hazardous heavy metal that caused serious problems for ecosystem at recent years. in this study, the effect of pb on seed germination, incipient growth and antioxidant enzymes of six common used turfgrasses was investigated. the results showed that after implementation of different concentrations (0, 1000, 2000 and 3000 µm) of pb, agropyron elongatum exhibited the h...

iron deficiency in soil reduces the quality of durum wheat leading to fe deficiency in human. thus, this experiment investigated the effects of foliar application of nano-iron oxide (2 and 4 g l-1), iron chelate (edta), (4 and 8 g l-1), iron sulfate (4 and 8 g l-1), and the control on grain yield and quality, yield components, chlorophyll and carotenoids contents, peroxidase (pox), catalase (ca...

in the present study, we examined the antioxidative activities of satureja khuzestanica essential oil (ske) and possible protective effect of ske on lipid profile, atherogenic index and liver enzyme markers in alloxan-induced type 1 diabetic rats. thirty male rats were randomly divided into three groups; group one as control, group two diabetic untreatment, and group three treatments with ske b...

in the present study we aimed to evaluate the effects of methanolic extracts of the bulbs of garlic (allium sativum l., alliaceae) and persian shallot (allium ascalonicum l., alliaceae ) and leaves of sage (salvia officinalis l., lamiaceae ), ase, aae and soe respectively, on the antioxidant enzymes such as superoxide dismutase (sod), glutathione peroxidase (gpx) and catalase (cat) activities an...

The chronic effect of environmental methomyl on the antioxidant system in testis Nile tilapia (Oreochromis niloticus) and its recovery pattern was investigated. Tilapia were exposed to sublethal concentrations 0.2, 2, 20 200 ?gL?1 for 30 days thereafter moved methomyl-free water 18 days. Antioxidant levels testis, including glutathione peroxidase, catalase, glutathione-S-transferase, reductase,...

Objectives: This study aimed to evaluate the effect of crocin and treadmill exercise on oxidative stress, sperm parameters, testis structure in streptozotocin (STZ)-induced diabetic rats. Materials Methods: In this experimental study, 64 rats induced by a single intraperitoneal (IP) injection STZ (50 mg/ kg) were assigned following groups (n=8/each): healthy control group, group treated daily w...

objective(s) sickle cell disease is a genetic disorder characterized by chronic haemolytic anaemia. haemoglobin s containing red blood cells may be susceptible to oxidative stress due to imbalance between production of reactive oxygen species and the countering effect of the various antioxidants present in the body. materials and methods we evaluated some antioxidant enzymes which include gluta...

peppermint (mentha piperita l.), a herbaceous and perennial species whichis produced mainly for the medicine and food. the peppermint plants were initiated from 10 cm-long rhizome cuttings followed by transferring into pots. the 48 h-treated plants with methyl jasmonate (mj) concentrations (0, 0.1, 0.5 mm) were assessed for their total soluble proteins, malondialdehyde (mda), chlorophylls a, b ...

catharanthus roseus is a medicinal and ornamental plant with growing attention toward its economical value. cell suspension from c. roseus were treated with 0 to 60mm of cadmium nitrate for 1, 3 and 6 days, then cell viability was determined using trypan blue and mtt assay. cell morphology was investigated using 0, 10, 30 and 50 mm of cadmium nitrate as selected dose for 3 days. callus of c.ros...
