Figure 5From: Sex differences in the impact of ozone on survival and alveolar macrophage function of mice after Klebsiella pneumoniae infectionIn vivophagocytosis ofK. pneumoniaeby alveolar macrophages from mice, exposed to ozone. Experimental design was as described in the legend for Figure 1 and the Methods section except that a dose of ~1.2 × 107 CFU/mouse of K. pneumoniae was used, and the mouse lungs were lavaged 1 h post-infection, as described in Methods. Alveolar macrophages were prepared, applied to slides by cytocentrifugation and stained for phagocytosis assessment by light microscopy (see Methods). Results were considered to be significant if p < 0.05 with t-test. (*) significant differences between males and females of the same group (i.e. O3 or FA); (**) significant differences between FA and O3 groups of mice of the same sex. The number of independent experiments was 5 and the number (n) of mice in each group that survived after the procedure is shown in the figure.Back to article page
