Effect of crocin on lung permeability in LPS-induced ARDS mice. Following the process shown in Fig. 1a, lung permeability was determined by FITC-albumin osmosis analysis (a, magnification ×200, scale bar 50 µm) and lung W–D ratio (c). b Fluorescence intensity analysis of a. All data are presented as means ± SD of three independent experiments. ^#p < 0.05 vs. control group, *p < 0.05 vs. LPS group
