Impact of fecal microbiota transplantation on TGF-β1/Smads/ERK signaling pathway of endotoxic acute lung injury in rats

摘要

HE staining of lung tissue of rats (× 200). In the NS group (a), there was no damage to alveolar structure, inflammation or hemorrhage. In the LPS group (b), lung tissue is severely damaged, massive hemorrhage of alveoli and alveolar septum, numerous erythrocytes. In the LPS + FMT group (c), there were less lung tissue destruction and less inflammatory cell infiltration
