Cultured quail myocytes were much more resistant to H2O2 toxicity than cultured mouse myocytes. The intracellular concentration of glutathione ([GSH]i) and the activity of gamma-glutamylcysteine synthetase (gamma-GCS) in quail heart cells were about five and three times higher, respectively, than in mouse heart cells, although catalase and glutathione peroxidase (GSHpx) activity was similar in ...

The study was designed to assess the relationship between red cell glutathione peroxidase and serum selenium as well as lipids and lipoprotein in HIV positive blood donors. Thirty five subjects consisting of twenty HIV positive blood donors with a mean age of 34±2.18 years and fifteen HIV negative blood donors with a mean age of 43±2.18 years controls were selected for this study. Erythrocyte g...

Purified enzymes were mixed to form a cell-free system that simulated the conditions for removal of hydrogen peroxide within human erythrocytes. Human glutathione peroxidase disposed of hydrogen peroxide (H2O2) at a rate that was only 17% of the rate at which human catalase simultaneously removed hydrogen peroxide. The relative rates observed were in agreement with the relative rates predicted ...

OBJECTIVE We aimed to determine the relationship between serum glutathione peroxidase and febrile seizure. MATERIALS & METHODS In this case-control study, 43 children with simple febrile seizure (case group) were compared with 43 febrile children without seizure (control group) in terms of serum glutathione peroxidase level, measured by ELISA method. This study was conducted in Qazvin Childre...

We conducted a comparative analysis of biochemical parameters for the ascorbate-glutathione cycle in non-transgenic and transgenic Nicotiana tabacum, plants cultivated heavy metal polluted soils. Transgenic had their genome bacterial acdS-gene encoding 1-aminocyclopropane-1-carboxylate deaminase (ACC-deaminase) enzyme. The introduction elevated concentrations copper, chromium, lead ions into so...

To the Editor: Ambade et al1 conducted an observational study to evaluate the potential serum biomarkers in subjects with COPD. The authors assessed superoxide dismutase-3, glutathione peroxidase, catalase, ceruloplasmin ferroxidase activity, C-reactive protein, and surfactant protein D in the serum of subjects with COPD and reported that ceruloplasmin ferroxidase activity and glutathione perox...

Introduction: Antioxidant enzymes protect cells against reactive oxygen species. This study investigated the effects of Curcumin and L-Carnitine supplementation on antioxidant enzymes in the body of basketball players after an acute bout of exercise. Methods: 30 female basketball players participated in this quasi-experimental study. After obtaining written consents, the participants were rand...

We determined selenium concentrations and activities of the selenoenzyme, glutathione peroxidase (EC 1.11.1.9), in the plasma and erythrocytes of 38 apparently healthy women. We determined selenium concentrations directly by polarized Zeeman-effect flameless atomic absorption spectroscopy. Within-run precision studies for the assays gave CVs of 5.6% for a mean erythrocyte selenium concentration...
