FIG. 1.

Differential effects of P. aeruginosa infection on ELF antioxidant levels. Groups of six to eight wild-type mice were instilled with agarose beads with and without P. aeruginosa, and bronchoalveolar lavage was performed on the third day of infection. Values were corrected for lavage dilution using the urea method and expressed as ELF concentrations. P. aeruginosa infection increased GSH (A) and urate (D) ELF levels three- and twofold, respectively. P. aeruginosa infection had similar effects on the level of GSSG (B) but no effect on ascorbate (C) levels.
