Use of a peroxynitrite scavenger prevented the stressor-induced increase in microbicidal activity. (A) The number of E. coli remaining alive in the cultures at the 90-min time point was significantly lower in the presence of splenic macrophages from SDR-exposed mice compared to nonstressed controls. (B) When the peroxynitrite scavenger FeTPPS was added to the cultures, there was no difference in E. coli levels in cultures containing cells from SDR exposed or from HCC control mice (*, P < 0.05; n = 7 HCC and n = 10 SDR from two different experiments).
