- Fasting period before study: overnight before until 3-4 h after dosing
- Housing: 3 animals/sex/cage in polycarbonate cages, containing purified sawdust as bedding material (Woody SPF, supplied by B.M.I., Helmond, The Netherlands)
- Diet: standard laboratory animal diet, Carfil Quality BVBA, Oud-Turnhout, Belgium, ad libitum
- Water: tap-water ad libitum
- Acclimation period: at least 5 days

ENVIRONMENTAL CONDITIONS
- Temperature (°C): 21
- Humidity (%): 50

Administration / exposure

Route of administration:
oral: gavage
Vehicle:
unchanged (no vehicle)
Details on oral exposure:
MAXIMUM DOSE VOLUME APPLIED: 2.17 mL/kg bw
Doses:
2000 mg/kg bw
No. of animals per sex per dose:
3
Control animals:
no
Details on study design:
- Duration of observation period following administration: 14 days
- Frequency of observations and weighing: animals were observed twice daily for mortality. Individual body weights were determined weekly (Days 1 (pre-administration), 8 and 15). Animals were observed for clinicals signs at periodic intervals on Day 1 and once daily thereafter.
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs, body weight
Statistics:
No statistical analysis was performed (the method used is not intended to allow the calcuation of a precise LD50 value)
