(step 1: 1/3 on day 3, 2/3 on day 5; step 2: 2/3 on day 3, 1/3 on day 4)
- 300 mg/kg bw: 0/6 animals died - Clinical signs:
- other: - 2000 mg/kg bw: decrease in spontaneous activity (6/6), decrease in muscle tone (1/6), decrease in righting reflex (1/6), and piloerection (4/6) (all signs from 48 hours post-treatment) - 300 mg/kg bw: No clinical signs related to the administeration of
- Gross pathology:
