Hematoxylin and eosin (H&E) staining of lung tissues following lipopolysaccharide (LPS)-induced lung injury. (A) Protective effects of baicalin against LPS-induced lung injury at various concentrations. A histopathological examination revealed blood capillary congestion, necrosis and exfoliation epithelium of the pulmonary alveoli, and the extravasation of fluid in lungs. (B) Immunohistochemical analysis of CX3CL1 expression in lung tissue following LPS-induced lung injury.
