Effects of the MPBL on acetic acid-induced writhing in mice

Groups	Dose (mg/kg)	No. of writhing	% inhibition
Group I	Vehicle	34.40
Group II	10	10.60	69.19*
Group III	100	19.80	42.44*
Group IV	200	12.27	64.53*

Values are mean±SEM, (n=5);

^*p<0.05 as compared with vehicle control (one-way ANOVA followed by Dunnett’s test). Group I animals received vehicle (1% Tween 80 in water), Group II received diclofenac Na 10 mg/kg body weight, Group III and Group IV were treated with 100 and 200 mg/kg body weight (p.o.) of the MPBL.
