Measures of alveolar-capillary permeability in mice after acid-induced lung injury. a Total protein content (in g.L−1) of the bronchoalveolar lavage (BAL) fluid and b Permeability index, as calculated as the BAL fluid-to-plasma ratio of the human serum albumin (HSA) concentration, in uninjured (Sham), acid-injured (HCl), and acid-injured mice treated with sevoflurane (HCl + Sevo) from day 0 to day 4 after injury. Values are presented as box and whisker plots with medians and interquartile ranges (n = 4–6 per group). Two-way ANOVA tests were performed; no statistical significance was found in a and b. c Representative images of accumulation on day 2 after injury of an intravenously injected, near-infrared fluorescent dye, as reported as relative fluorescence units (RFU), in isolated lungs and d in the BAL fluid of uninjured (Sham), acid-injured (HCl), and acid-injured mice treated with sevoflurane (HCl + Sevo)
