Time course of the effect of EA on the behaviour of TNBS-induced mice. a Effect of EA on the mechanical withdrawal threshold of TNBS-induced mice. b Effect of EA on body weight (body weight divided by the baseline *%). c Effect of EA on colon length. d Effect of EA on diarrhoea score. EA treatment was applied 1 day after TNBS injection once daily for 7 consecutive days. Data were expressed as the means ± SEM (n = 10 mice per group). ^*P < 0.05, compared with the control group; ^#P < 0.05, compared with the TNBS group; ^△P < 0.05, compared with the TNBS+EA group
