red cells suspended in either defined medium or buffered plasma were oxidatively stressed by incubation in the presence of 1,4-naphthoquinone-2-sulfonate at concentrations which caused less than 50 % methemoglobin accumulation , stimulation of the hexose monophosphate shunt to less than 15 % of capacity , and about a 30 % increase in flux through glycolysis .
