- Fasting period before study: overnight (prior to dosing) until approximately 3.5 hours after administration
- Housing: individually in polycarbonate cages containing purified sawdust as bedding material
- Diet: standard pelleted laboratory animal diet (RMH-B, Hope Farms, Woerden, The Netherlands)
- Water: tap-water, ad libitum

Administration / exposure

Route of administration:
oral: gavage
Vehicle:
unchanged (no vehicle)
Doses:
2000 mg/kg bw
No. of animals per sex per dose:
5
Control animals:
no
Details on study design:
- Duration of observation period following administration: 14 days
- Frequency of observations and weighing: The animals were observed for any signs of toxicity approximately once every two hours after dosing and once daily thereafter for 14 days. Individual bodyweights were measured weekly.
- Necropsy of survivors performed: Yes, at the end of the study (day 14), all animals were anaesthetised by CO2/O2 inhalation, subsequently killed by CO2 and subjected to necropsy
- Other examinations performed: clinical signs, body weight

Results and discussion

Effect levels
Sex:
male/female
Dose descriptor:
LD50
Effect level:

Based on:
test mat.
Mortality:
No mortality occurred.
Clinical signs:
other: No signs of systemic toxicity were observed during the 14 day observation period.
Gross pathology:
