Applicant's summary and conclusion
- Conclusions:
- The negative teratogenic effects on foetal body weight,foetal loss and malformation by the test chemical was observed at dose concentration 1.5 - 5 ml/animal/day (equivalent to 1500 -5000 mg/kg bw/d) in 6-14 or 11-16 days of gestation period. Thus, LOAEL (No observed adversed effect level) for teratogenicity study is considered to be 1.5 - 5 ml/animal/day (equivalent to 1500 -5000 ng/kg bw/d).
- Executive summary:
A teratogenic study was conducted to evaluate the foetal body weight,foetal loss and any kind of malformation by the test chemical to female rats orally dosed on gestational days 6-14 or 11-16 with 1.5 -5 ml/animal/day (equivalent to 1500 -5000 ng/kg bw/d). The test chemical was shown to have negative teratogenic effects as Foetal loss and foetal body weight remained within normal limits and no malformations were observed in rats after administration of dosage 1.5 -5 ml/animal/day (equivalent to 1500 -5000 mg/kg bw/d) of the test chemical. Since LOAEL (Low observed adversed effect level) is 1.5 -5 ml/animal/day (equivalent to 1500 -5000 mg/kg bw), it is regarded that there is no teratogenic effectsin the fetuses at concentrations 1.5 -5ml/animal/day (equivalent to 1500 -5000 mg/kg bw/d) when administered orally.
