title: Haemoglobin oxidation in whole blood samples from sheep in relation to glutathione peroxidase activity.
abstract: A high correlation was observed between H2O2-induced oxidation of haemoglobin and glutathione peroxidase activity in whole blood samples from sheep. A role of this enzyme in the prevention of oxidative damage to the erythrocyte and its contents has been previously demonstrated. The possibility of using haemoglobin oxidation in whole blood as an alternative assessment of glutathione peroxidase activity and hence of selenium status is proposed.
