Antioxidant enzymatic systems and oxidative stress in erythrocytes with G6PD deficiency: effect of deferoxamine.

In the present study we have assayed the effect of divicine in G6PD-deficient red blood cells in the presence of deferoxamine (iron-chelating drug) and NaN3 (inhibitor of catalase). The effect of divicine has been compared to oxidative stress by H2O2; haemolysis is regarded as an index of cellular toxicity. In addition, we have tested antioxidant enzymatic systems. No significant change in antioxidant enzymatic systems was found in RBCs from subjects with G6PD deficiency when compared to the control group, either in oxidative haemolysis by divicine or by H2O2; a significant decrease in oxidative haemolysis by H2O2 was observed in the presence of deferoxamine, whereas no change was found in oxidative haemolysis by divicine. The replacement of incubation medium by homologous plasma or the supplementation with bovine serum albumin resulted in a marked decrease of percentage of haemolysis by divicine.[1]
