Twenty-five BALB/C mice were randomly devided into five groups. Negative control received only CMC-Na 1.5 % and Tween 80 0.5% also aquadest an hour after the first administration; Positive control group that administered CMC-Na 1.5 % and Tween 80 0.5% then continued received 20 mg/kgBW of lead acetate, Treatment group was received 200; 400 and 800 mg/kgBW of propolis first and then an hour after that received 20 mg/kgBW of lead acetate.
