Wet lung weights (an indicator of edema and congestion associated with pneumonitis) among 14.6 Gy WTLI female CBA/J mice. Error bar represents the standard error in each study group. Analysis by pairwise comparison among groups was performed considering 0.05 as the level of significance. There was significant difference between the WTLI-alone group (mean = 346.0, SEM = 23.20) and both the WTLI-AEOL 10150, 25 mg/kg (mean = 244.0, SEM = 18.8, P = 0.002) group and WTLI-AEOL 10150, 40 mg/kg (mean = 261.0, SEM = 23.9, P = 0.046) group. The average wet lung weight of all sham-irradiated cohorts was 143.5 mg.
