(A) Frequency of cough in 4 min. (B) Latent period of cough was measured in the model group treated with the PEC and positive drug asmeton. Values are presented as mean ± SD. ^^p < 0.01, ^^^p < 0.001 compared with the sham group; #p < 0.05, ##p < 0.01, ###p < 0.001 compared with the ovalbumin-induced airway inflammation model with cough group.
