Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- 6.06 other: g/kg body weight
- 95% CL:
- 5.64 - 6.51
- Remarks on result:
- other: Authors calculated the LD50 value based on mortality-figures
- Mortality:
- The number of male deaths in the 3.00, 3.60, 4.32, 5.19, or 6.21 g/kg body weight groups was 0, 0, 0, 1, and 4 animals, respectively. The number of female deaths in the 3.00, 3.60, 4.32, 5.19, or 6.21 g/kg body weight groups was 0, 0, 0, 1, and 3 animals, respectively. Deaths occurred between 5 and 21 hours after treatment. Afterwards the survivors recovered gradually and looked quite healthy again at the end of the observation period.
- Clinical signs:
- Within a few hours after dosing the rats showed sluggishness, humpback behaviour and severe diarrhoea.
- Body weight:
- Individual body weight measurements were not reported. A range of body weights was reported only at the beginning of the study.
- Gross pathology:
- Macroscopic examination of the survivors at autopsy revealed no treatment-related gross alterations.
Applicant's summary and conclusion
- Interpretation of results:
