Inhalation of salmeterol does not influence inflammation in NTHi infected lungs. Mice inhaled vehicle (A, C) or salmeterol (B, D) before intranasal inoculation with 107 CFU NTHi. Mice (n = 4 per group) were sacrificed 6 (A, B) and 48 hours (C, D) post-infection and whole lungs were examined for inflammation. At 6 h post-infection, all mice displayed mild inflammation while at 48 h lung inflammation was more pronounced and diffuse. The inflammation scored did not reveal a difference between vehicle and salmeterol treated animals at both timepoints. H&E staining, magnification 10×.
