- Age at study initiation: 8-12 weeks
- Weight at study initiation: males 264-280 gr; females 200-242 gr
- Fasting period before study: overnight before dosing and 2 hr after dosing
- Housing: animals were housed in groups of up to five by sex in solid-floor polypropylene cages furnished with woodflakes.
- Diet (e.g. ad libitum): mouse and rat No 1 special diets services Limited WithamEssex (UK) was allowed during the study
- Water (e.g. ad libitum): mains drinking water.
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 19-22
- Humidity (%): 44-58
- Air changes (per hr): 15
- Photoperiod (hrs dark / hrs light): 12-12
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- unchanged (no vehicle)
- Details on oral exposure:
- All animals were dosed once by gavage using metal cannula attached to graduated syringe.
The volume administrated to each animal was calculated according to its fasted bodyweight at the time of dosing. - Doses:
- Range finder: Dose level 5000 mg/kg, Concentration 500 mg/ml, Dose volume 10 ml/kg
Main test: Range finder: Dose level 5000 mg/kg, Concentration 500 mg/ml, Dose volume 10 ml/kg - No. of animals per sex per dose:
- Range finder, one male and one female
Main test: five males and five females - Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: range finder 5 days; main study 14 days
- Frequency of observations and weighing: 0.5, 1,2 and 4 hr after dosing and subsequently once daily for 5/14 days . Range finder: Individual bodyweights were recorded on the day of dosing to allow calculation of individual treatment volumes.
Main study: individual bodyweights were recorder prior to dosing on day 0 and on day 7 and 14.
- Necropsy of survivors performed:Range finder: no; Main test: yes
- Other examinations performed: clinical signs, body weight,organ weights, histopathology, other: Main test: gross pathological examination, e.g external examination and opening of the abdominal and thoractic cavities for examination of major organs.
