Lung histological sections after a 5-h low tidal volume mechanical ventilation (MV) following either a lipopolysaccharide (LPS) aspiration or vehicle (saline) in wild type (WT) and interleukin-6 knock-out (KO) mice receiving either recombinant human interleukin-6 (rHuIL-6) or vehicle. Lungs underwent fixation (paraformaldehyde 4%), paraffin embedding, staining with hematoxylin and eosin, and examination under a light microscope. Magnification x10 on the two uppers rows of images and X40 on the lower row of pictures. Scale bar: 50μm. N = 6 to 8 animals per group
