Lipid peroxidation of ghosts from control, uninfected, and infected erythrocytes. RBC ghosts were assayed for TBARSs before or after induction for 3 hours at 37°C with the pro-oxidant system iron-ascorbate. Results (mean ± SD) are expressed as nanomole TBARS per micromole red cell phospholipids. ○P < .01 versus NRBCs of the same age. ^*P < .01 versus NRBCs and URBCs. (A) TBARSs at basal conditions. (B) TBARSs after iron/ascorbate challenge.
