Figure 1From: Mechanical ventilation modulates TLR4 and IRAK-3 in a non-infectious, ventilator-induced lung injury modelRepresentative histopathologic features of lungs from all animal groups. Left panel: normal, unventilated lung; Middle panel: low tidal volume (6 mL/kg): lungs did not exhibit significant changes compared to healthy, unventilated lungs. Right panel: high tidal volume (20 mL/kg): inflammatory infiltrates and perivascular edema (hematoxylin & eosin staining; original magnification ×200).Back to article page
