Administration / exposure

Route of administration:
oral: gavage
Vehicle:
other: water/glycerol mixture
Doses:
2000 mg/kg
No. of animals per sex per dose:
3 animals per dose
Control animals:
no
Details on study design:
At the first step, a group of 3 animals was treated with the starting dose of 2000 mg.kg body weight, followed by an additionnal group of 3 animals at the same dose level.
General observation were performed twice on Day 1 (60 min ± 30 min post-dose and again between 3 and 4h post-dose), and then daily for 14 days after administration of the test item. Functional and neurobehavioural tests were performed on Day 1 (60 min ± 30 min post-dose), on Day 7 and on Day 14. Animals were weighted on Days 1, 7, 14 and 15 (day of necroscopy).
Statistics:
All animals surviving ti the end of the 14-day monitoring period were submitted to gross necroscopy.
