Fig. 1. Effect of fennel on lactate dehydrogenase (LDH) activity in BALF of LPS-treated mice. Mice were intratracheally administered LPS (1.5 mg/kg) 1 h after intraperitoneal injection of 1% Tween 80-saline (vehicle), fennel (125, 250, 500µl/kg), or DEX (1 mg/kg). The activity of LDH in BALF was measured to evaluate cell damage. Data are reported as mean±S.E.M. (n=7~10 per group). ^###p<0.001 compared with vehicle group; ^**p<0.01, ^***p<0.001 compared with the vehicle+LPS group.
