Table 1. Histopathological lung injury score, interalveolar septal thickness and the number of neutrophils in alveolar spaces in mice at 24 h during LPS-induced lung injury.

Measure	Untreated control	LPS and PBS	LPS and CXCR4 antagonist
Lung injury score	1.1±0.1	3.3±0.1	2.5±0.2*
Septal thickness (µm)	1.6±0.1	2.9±0.1	2.5±0.1*
No. of neutrophils in 100 alveoli	1.2±0.3	68.3±4.6	48.5±2.9*

Abbreviations: LPS, lipopolysaccharide; PBS, phosphate-buffered saline.

Data are represented as mean±s.e.m. n=6 per group.

*P<0.01 versus LPS and PBS group.
