To assess the potential role of salidroside in CLP-induced ALI, the mRNA and protein expression levels of PPAR-γ, NF-κβ p65 and Iκβ in the lung tissue of the lipopolysaccharide (LPS)-induced ALI rats were determined using qPCR and western blot analysis at 24 h after the CLP challenge. This evidence concerns the gene NFKB1 and acute respiratory distress syndrome.
