- Weight at study initiation: mean weight of 6 animals: 177.7 g
- Fasting period before study: 16 hours before administration
- Housing: Makrolon cage, type III, single housing with Bedding: H 15005-29; Ssniff, Spezialitäten GmbH (Experimental Animal Diets Inc., 59494 Soest, Germany) and Enrichment: Wooden gnawing blocks (Type NGM E-022) ; ABEDD® LAB & VET Service GmbH, Hasnerstraße 84/6; 1160 Wien – Austria

- Water: Tap water, ad libitum
- Acclimation period: at least 5 days before
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 22 ± 3
- Humidity (%): 30 - 70
- Air changes (per hr): approx. 10
- Photoperiod (hrs dark / hrs light): 12/12
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- CMC (carboxymethyl cellulose)
- Remarks:
- 0.5% solution in deionized water
- Details on oral exposure:
- VEHICLE
- Concentration in vehicle: 20 g/mL
- Amount of vehicle (if gavage): 10 mL/kg bw
- Justification for choice of vehicle: A good homogeneity in water could not be guaranteed, because the test item preparation was a suspension. Therefore a 0.5% solution of CMC in deionized water was applied - Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- 6
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 d
- Frequency of observations and weighing: Individual body weights shortly before administration (day 0), weekly thereafter and on the last day of observation. Clinical signs for each animal were recorded several times on the day of administration and at least once during each workday thereafter. A check for any dead or moribund animals was made at least once each workday.
- 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. No histological examinations were performed.
Results and discussion
Effect levels
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Mortality:
- No mortality occurred.
- Clinical signs:
- other: All animals of the first 2000 mg/kg bw. test group showed a red discoloration of feces from study day 1 until day 3 and red discolored urine from day 2 until day 3. In addition, two of these animals showed impaired general state and piloerection from hour
- Gross pathology:
- There were no macroscopic pathological findings in all animals sacrificed at the end of the observation period.
