Incubation with l-carnitine and baicalin restored hyperoxia-induced reduction of migration in cultured lung endothelial cells. Cells were exposed to hyperoxia (50% O₂/5% CO₂, 95% O₂/5% CO₂) or air (21% O₂/5% CO₂) for 24 h followed by normoxia for 16 h. Cells were incubated with l-carnitine (LCT, 40 and 80 mg/L) and baicalin (BLN, 22.5 and 45 mg/L) for 12 h during the air recovery phase. Migration was measured using scratch assay. N = 6. *P < 0.05, ***P < 0.001 vs air. ^†P < 0.05, ^††P < 0.01, vs corresponding O₂/veh group using one-way ANOVA followed by Tukey's multiple comparison test
