TABLE 5.

Myeloperoxidase (MPO) analysis

Group (n) Median 25% 75% p < 0.05 vs.
Normoxia		 p < 0.05 vs.
Saline
Normoxia (n = 5) 0 0 0 - no
24-hr hyperoxia (n = 5) 0 0 0 no no
24-hr saline (n = 4) 1.9 0.6 4.4 no -
24-hr LPS (n = 5) 9.6 3.1 20.0 yes no

Numbers of MPO positive cells per field were counted by reviewers blinded to the treatment group and compared by ANOVA on ranks. n is the number of rats. Images from LPS-treated rats exhibited more MPO cells than normoxia rats, consistent with neutrophil infiltration.
