BACKGROUND Nitrite is a nitric oxide (NO) metabolite in tissues and blood, which can be converted to NO under hypoxia to facilitate tissue perfusion. Although nitrite is known to cause vasodilation following its reduction to NO, the effect of nitrite on platelet activity remains unclear. In this study, the effect of nitrite and nitrite+erythrocytes, with(More)
Artemisinin exerts the antimalarial activity through activation by heme. The hemolysis in malaria results in the elevated levels of plasma heme which may affect the activity of artemisinin. We hypothesized that the extracellular heme would potentiate the antimalarial activity of artemisinin. Hemin (ferric heme) at the pathologic concentrations enhanced the(More)
