The effect of blocking abdominal lymphatic flow on histopathological change of lung in AHNP rats. A: Lung in a sham operation animal 6 hr after injection of saline, mild alveolar septum edema and inflammatory infiltrate. B: AHNP group, diffuse pulmonary capillary dilatation and congestion, intense alveolar septum swelling and breakage, part of alveolar structural damage and heavy neutrophils infiltration. C and D: AHNP + ligation and AHNP + drainage group, moderate to severe alveolar septum swelling and neutrophils infiltration (H & E, × 100).
