Applicant's summary and conclusion
- Conclusions:
- NOAEL was considered to be 616mg/kg/day for F0 and F1 geneartion when CFE-S female rats were treated with test material orally.
- Executive summary:
In a Teratology study,CFE-S female rats were treated with test material in the concentration of 0, 195 and 616 mg/kg/day orally in diet fromday 6 to day 15 of gestation. No adverse effect onaverage number of implantation sites, live pups or in the number of females with one or more resorption sites were observed in treated female rats. No effect on fetuses weight were observed in treated female rats. In addition, No were gross abnormalities, visceral and skeletal abnormalities were observed in fetusesoftreated female rats. Therefore, NOAEL was considered to be 616mg/kg/day for F0 and F1 geneartion when CFE-S female rats were treated with test material orally in diet for 10 days.
