UFH alleviates LPS-induced acute lung injury in mice. Mice received an intraperitoneal injection of LPS with or without pretreatment with UFH. The mice were sacrificed 6 h post LPS administration, and the lung sections were subjected to hematoxylin and eosin staining for pathological examination. Representative images of each group (n=4/group) are shown. Magnification, ×200. UFH, unfractionated heparin; LPS, lipopolysaccharide.
