From: Comparison of direct and indirect models of early induced acute lung injury
Representative images of a–e hematoxylin and eosin-stained lung tissue sections. Evidence of lung injury was observed in LPS and HCl-LPS rats (c and d) while no lung injury was detected in HCl, CLPor 0.9% NaCl rats (a, b, e). f Histological score in animals 24 h after induction of the injury. Data are presented as mean ± SEM. LPS or HCl-LPS: ***p < 0.0001 vs 0.9% NaCl, HCl, CLP; CLP: **p < 0.001 vs 0.9% NaCl or HCl
