Test animals
- Species:
- rat
- Strain:
- other: CD
- Sex:
- male/female
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Source: Charles River UK Limited, Margate, Kent, England
- Age at study initiation: 4-6 weeks
- Weight at study initiation: 108-142 g
- Fasting: overnight prior to dosing and for approximately 4 hours after dosing.
- Housing: grouped by sex in metal cages with wire mesh floors.
- Diet: Standard laboratory rodent diet (Labsure LAD-1) ad libitum (see Appendix 1, attached)
- Water: ad libitum (see Appendix 2, attached, for results of routine chemical examination of water at source (Grafham Final Water) as conducted by Anglian Water Authority)
- Acclimation period: 8 days prior to start of study
ENVIRONMENTAL CONDITIONS
- Temperature: 21-24 ºC
- Humidity: mean value 67 %
- Air changes: approximately 15 per hour
- Photoperiod: controlled by a time switch to provide 12 hours artificial light in each 24 hour period.
Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- unchanged (no vehicle)
- Details on oral exposure:
- The appropriate dose volume of the test substance was administered to each rat using a syringe and plastic catheter (8 choke)
- Doses:
- Single dose
- No. of animals per sex per dose:
- 3 males and 3 females
- Control animals:
- no
- Details on study design:
- - Each animal was identified by cage number and ear punching.
- Each cage was identified by a coloured label displaying the dose level, study schedule number and the initials of the study director.
- Animals were observed soon after dosing and at frequent intervals for the remainder of day one (a minimum period of five hours).
- On subsequent days the animals were observed once in the morning and again at the end of the experimental day.
- The latter observation was at approximately 16:30 hours on weekdays or 11:30 hours on Saturday and Sunday.
- Clinical signs were recorded at each observation.
- All animals were observed for 14 days after dosing.
- Nature, severity, approximate time of onset and duration of each toxic sign was recorded.
- Individual bodyweights of rats were recorded on days 1, 8 and 15.
- All animals were killed on day 15 by cervical dislocation and were subjected to a macroscopic post mortem examination, which consisted of opening the abdominal and thoracic cavities.
- Macroscopic appearance of abnormal organs when present was recorded.
