Figure 5: (a) Initial study of the effect of 0.5 mg myeloperoxidase (MPO)/mouse on survival depicted as Kaplan-Meier survivor curves for naïve BALB/c female mice over a 5-day period following IP injection of an 90% lethal dose (LD90) (0.4 mg lipopolysaccharide (LPS)/mouse; i.e., about 22 mg/kg) dose on day 1. (b) Follow-up study showing Kaplan-Meier survivor curves using 2.5 and 5.0 mg MPO/mouse and also 2.5 and 5.0 mg eosinophil peroxidase (EPO)/mouse.
