- Diet: Rat and Mouse Expanded Diet No. 1 (Special Diet Services Ltd., Witham, Essex, UK), ad libitum
- Water: ad libitum
- Acclimation period: 5 days

ENVIRONMENTAL CONDITIONS
- Temperature (°C): 19-21
- Humidity (%): 40-65
- Air changes (per hr): ca. 15
- Photoperiod (hrs dark / hrs light): 12/12

Administration / exposure

Route of administration:
oral: gavage
Vehicle:
unchanged (no vehicle)
Details on oral exposure:
VEHICLE
- Concentration in vehicle: 500 mg/mL
- Amount of vehicle (if gavage): 10 mL/kg bw

MAXIMUM DOSE VOLUME APPLIED: 10 mL/kg bw

DOSAGE PREPARATION: For the purpose of the study, the test material was freshly prepared as a solution/suspension at the appropriate concentration in arachis oil B.P. The preparation was warmed to aid solubilisation.
Doses:
5000 mg/kg bw
No. of animals per sex per dose:
5
Control animals:
other: not required
Details on study design:
- Duration of observation period following administration: 14 days
- Frequency of observations and weighing: animals were observed 1 and 4 h after dosing and subsequently once daily for 14 days. Deaths and evidence of overt toxicity were recorded at each observation. Individual body weights were recorded on the day of treatment (Day 0) and on Days 7 and 14.
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs, body weight, gross necropsy
