Role of DEX on the levels of inflammatory molecules in lung sample and BALF from WT rats with CLP-stimulated ALI. Rats were infused continuously with DEX or NS through the femoral vein cannula 30 min after CLP. Lung sample and BALF were harvested at 24 h after CLP to determine inflammatory molecules TNF-α (A, D), IL-1β (B, E), and IL-6 (C, F). *P<0.05, #P<0.01 CLP vs. CLP+DEX. DEX, dexmedetomidine.
