- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Source: Charles River Wiga GmbH, Germany
- Females nulliparous and non-pregnant: yes
- Age at study initiation: approx. 10 weeks
- Weight at study initiation: animals of comparable weight (± 20% of the mean weight of 181.3 g)
- Fasting period before study: Feed was withdrawn from the animals at least 16 hours before administration, but water was available ad libitum.
- Housing: Single housing; Makrolon cage, type III
- Diet: VRF1(P); SDS Special Diets Services, 67122 Altrip, Germany, ad libitum
- Water: Tap water ad libitum
- Acclimation period: Acclimatization period of at least 5 days before the beginning of the experimental phase; during the acclimatization period, the animals were accustomed to the environmental conditions of the study and to the diet.
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 22°C ± 3
- Humidity (%): 30 – 70
- Air changes (per hr): Approx. 10
- Photoperiod (hrs dark / hrs light): 12 h / 12 h (6.00 p.m. – 6.00 a.m. / 6.00 a.m. – 6.00 p.m.)
There were no deviations from these ranges, which influenced the results of the study.
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- corn oil
- Details on oral exposure:
- VEHICLE
- Concentration in vehicle: 20 g/100mL
- Amount of vehicle (if gavage): 10 mL/kg bw
MAXIMUM DOSE VOLUME APPLIED: 2000 mg/kg
DOSAGE PREPARATION (if unusual): The test item was prepared for each test group shortly before administration by stirring with a high speed homogenizer (Ultra-Turrax) and a magnetic stirrer.
The homogeneity of the test item preparation during administration was ensured by stirring with a magnetic stirrer.
CLASS METHOD (if applicable)
- Rationale for the selection of the starting dose: By request of the sponsor a starting dose of 2000 mg/kg bw was chosen in the first step with 3 female animals. Because no mortality occurred, 2000 mg/kg bw were administered to another group of 3 female animals in the second step. - Doses:
- 2000 mg/kg
- No. of animals per sex per dose:
- 6
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Individual body weights shortly before administration (day 0), weekly thereafter and on the last day of observation.
- Necropsy of survivors performed: yes. Necropsy with gross-pathology examination was performed on the last day of the observation period after sacrifice by CO2-inhalation in a chamber with gradually increasing concentrations.
- Other examinations performed:
- clinical signs: Clinical signs for each animal were recorded several times on the day of administration and at least once during each workday thereafter.
- mortality: A check for any dead or moribund animals was made at least once each workday.
