Results and discussion
Effect levels
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Remarks on result:
- other: According to OECD Guideline 423, Annex 2d, a cut-off value of 5000 mg/kg bw was derived based on a limit test with 2000 mg/kg bw, since no mortality occurred in any step.
- Mortality:
- No mortality occurred.
- Clinical signs:
- other: At 300 mg/kg bw hunched posture and piloerection were noted for all animals between Days 1 and 4. At 2000 mg/kg bw hunched posture and piloerection were noted in 3/6 animals on Day 1.
- Gross pathology:
- At 300 mg/kg bw macroscopic post mortem examination did not reveal any abnormalities.
At 2000 mg/kg bw abnormalities of the liver (several, beige, focus/foci) were found in two animals, at macroscopic examination. Macroscopic examination of the other animals did not reveal any abnormalities.
