Abstract: Aim To explore the protective effects of dl-praeruptorin ( Pd-Ia) against acute lung injury induced by lipopolysaccharide ( LPS ) .Methods Acute lung injury model was induced by intranasal instillation LPS, and Pd-Ia was administered by intraperitoneal in-jection after 1 h of LPS exposure .Lung tissue samples were collected after 24 h of LPS administration to in-vestigate the role of Pd-Ia in acute lung injury .Results Pathomorpholoy showed a marked improvement of in-flammatory cell infiltration in Pd-Ia treated group , cel-lular staining also indicated a marked decrease of in-flammatory cells in BALF, and quantitative PCR and ELISA revealed a significant inhibition of cytokine IL-6,TNF-α, IL-1β, and chemokine MIP-1α, MIP-2 ex-pression .Pd-Ia attenuated LPS-induced histological se-verities and TNF-α, IL-6, IL-1β,MIP-1αand MIP-2 production .Conclusion Pd-Ia can alleviate the lung injury by ameliorating inflammation in lung .
