AEL induces rat paw edema. AEL(100 and 200 μg/paw) was injected in the animal right hind paws (s.c. intraplantar). Edema was measured 0.5, 1, 2, 3, 4, 5 and 6 h after AEL injection and expressed as the mean ± S.D. (n = 6) of the increase in paw volume (mL). ** p < 0.01 compared with animals injected with saline only (Sal).
