Concentration of oxyhemoglobin and methemoglobin (μmol/10¹⁰ cells) in (A) supernatant and (B) pellet at 4 h of incubation of erythrocytes. Erythrocyte suspension at 5% hematocrit was incubated at 37 °C in the absence or presence of 50 mmol/L AAPH. Values are expressed as mean ± standard deviation (n = 5). Significantly different in relation to AAPH: *p < 0.05; **p < 0.01 (t-test).
