Administration / exposure

Route of administration:

oral: gavage

Vehicle:

other: sesame oil

Details on oral exposure:

VEHICLE: The animals received the compound as a 20 % solution in sesame oil.
MAXIMUM DOSE VOLUME APPLIED: 10 mL/kg bw
DOSAGE PREPARATION: The test substance was dissolved in the stated concentration in sesame oil and distributed homogeneously by means of a magnetic stirrer. The stability and the homogeneity of the test substance in the vehicle was determined by analytical methods.

Doses:

2000 mg/kg bw

5

Control animals:

no

Details on study design:

- Duration of observation period following administration: 14 days
- Frequency of observations: Symptoms were recorded twice every day (in the morning and in the afternoon), on weekends and public holidays only once.
- Frequency of weighing: once a week
- Necropsy of survivors performed: yes
