Figure 4

Effect of LPS and hydrogen sulfide inhalation on systemic inflammation. 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). Blood samples were withdrawn by intracardiac punctation. Myeloperoxidase (MPO, A) and IL-1β (B) contents were quantified by ELISA in serum. Graphs represent means ± SEM, n = 6-8/group. ANOVA on Ranks (Dunn`s posthoc test), #P < 0.05 vs. PBS + H2S group.
