Applicant's summary and conclusion
- Conclusions:
- The administration of up to 189 mg/kg (body weight) of the
test material to pregnant mice for 10 consecutive days had
no clearly discernible effect on nidation or on maternal or
fetal survival. The number of abnormalities seen in either
soft or skeletal tissues of the test groups did not differ
from the number occurring spontaneously in the sham-treated
controls.
