Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): negative
Under the test conditions, test material was found to be non-mutagenic. - Executive summary:
A micronucleus test on mouse bone marrow was conducted to evaluate the mutagenic potential of the test material.
Male and female NMRI mice were used for the study. Feed and water were provided ad libitum. 4 animals (2 male, 2 female) were used in each treatment and control groups. 86.3, 57.5 and 28.8 mg/kg doses were administered i.p. at 0 and 24 h. Bone marrow smears were prepared at 30 h. 1000 polychromatic erythrocytes were scored per mouse. Significance was calculated according to the Kastenbaum-Bowman tables.
Under the test conditions, test material was found to be non-mutagenic.
