Figure 2

Effect of LPS and hydrogen sulfide inhalation on lung damage. As controls, mice received phosphate buffered saline (PBS, intranasally) and were kept in room air or in 80 ppm H2S for 6 h (plus 1 h pretreatment). LPS-treated mice (LPS treatment, i.n.) were either kept in room air or in 80 ppm H2S for 6 h (plus 1 h pretreatment). Sections from the left lung lobe were stained with hematoxylin and eosin. High power fields were randomly assigned to measure alveolar wall thickness (A), to count total infiltrate numbers (B), and to calculate an acute lung injury (ALI) score (C). Data represent means ± SEM for n = 7-8/group. ANOVA on Ranks (A + B, Dunn`s posthoc test) and ANOVA (C; Student-Newman-Keuls posthoc test), *P < 0.05 vs. PBS + air group; #P < 0.05 vs. PBS + H2S group; §P < 0.05 vs. LPS + H2S group.
