AOLT-induced ALI was attenuated by propofol application. Rats were exposed to propofol (50 mg/kg, intraperitoneally) or DMSO for 3 days before AOLT and all samples were obtained 8 h after reperfusion. a, b Cx43 expression of lungs determined with immunohistochemisty and western blotting. c Pathological damage of lungs (H&E staining; original magnification 200×). d Water content of the lung tissues. e–i Levels of LPS, TNF-α, IL-1β, IL-6 and IL-8 alternation. Vehicle control of propofol was fat milk, n = 6, *P < 0.05 vs Sham; ^#P < 0.05 vs AOLT
