- Fasting period before study: food was removed 1 day before test substance administration (Day -1) and then redistributed 4 h after treatment.
- Housing: rats were housed in groups of 3 in solid-bottomed clear polycarbonate cages with a stainless steel mesh lid. Each cage contained sawdust bedding.
- Diet: pelleted diet M20 (SDS), ad libitum
- Water: tap-water from the public distribution system, ad libitum
- Acclimation period: at least 5 days

ENVIRONMENTAL CONDITIONS

Administration / exposure

Route of administration:
oral: gavage
Vehicle:
olive oil
Details on oral exposure:
VEHICLE
- Amount of vehicle (if gavage): 10 mL/kg bw
Doses:
2000 mg/kg bw
No. of animals per sex per dose:
3 (for each step)
Control animals:
other: not required
Details on study design:
- Duration of observation period following administration: 14 days
- Frequency of observations and weighing: each animal was weighed on Day 0 (before test substance administration), 2, 7 and 14. Systemic examinations were carried out daily during the 14-day observation period.
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs, body weights, necropsy included macroscopic examination of animals
Statistics:
For body weights, mean values and standard deviations were calculated for all animals.
