Abstract: Purpose: To study the mutagenicity of Cultured Calculus Bovis. Methods: The studies were conducted with Ames test, micronuclei test and in vitro chromosome aberration test on human lymphocyte. Results: ① The results of Ames test showed no mutagenic effects with the concentration ranged from 1 250 μg / plate to 10 000 μg / plate. ② In micronuclei test, the mice orally received 50, 150, 500 mg / kg respectively per day for 2 days, no mutagenic effects were observed; and no significant reduction was observed on PCE / NCE ratio, compared with that of the negative control group(P>0.05). ③ The in vitro chromosome aberration test on human lymphocyte showed a negative result with the sample concentration ranged from 1 μg / ml to 100 μg / ml. Conclusion: No mutagenicity was found with Cultured Calculus Bovis in this experimentation.

Key words: Cultured Calculus Bovis, Mutagenicity, Chromosome aberration
