- Housing: The rabbits were housed individually in plastic cages with perforated floors
- Diet: Each rabbit was offered 125 g of a standard laboratory rabbit diet (Rabbit GD Diet Pellets supplied by Highgate Farm) per day. The animals were given a dietary supplement of hay.
- Water (ad libitum): Drinking water
- Acclimation period: At least 14 weeks prior to the start of the study.
During the acclimatisation and study period the animals were given small soft white untreated wood blocks for environmental enrichment.
ENVIRONMENTAL CONDITIONS
- Temperature: 16 to 20°C
- Relative humidity: 40 to 70%
- Photoperiod (hrs dark / hrs light): 12/12 - Type of coverage:
- semiocclusive
- Preparation of test site:
- clipped
- Vehicle:
- water
- Controls:
- no
- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied (volume or weight with unit): The treatment site was ‘wetted’ with 0.5 mL of reverse osmosis water and approximately 0.5 g of the test
substance was applied. - Duration of treatment / exposure:
- One animal (acted as a preliminary screen): three minutes, one or four hour exposure
Two additional animals: 4 hour exposure - Observation period:
- Examination of the treated skin was made on removal of the dressings (for 3 minute or one hour exposures) and approximately 1, 24, 48 and 72 hours later.
- Number of animals:
- 3 male rabbits
- Details on study design:
- A single animal received three exposures (of three minutes, one or four hours duration) in a step-wise manner and acted as a preliminary screen. In the absence of a severe effect on removal of the dressings the next exposure was initiated.
Two additional animals were treated with the test item for four hours.
TEST SITE
On the day before application of the test substance, hair was removed with clippers from the dorso-lumbar region of each rabbit exposing an appropriate sized area of skin. The treatment site was ‘wetted’ with the vehicle and the test substance was applied under a 2-ply 25 mm x 25 mm porous gauze pad secured with ‘blenderm’ surgical tape to intact skin sites on three animals. An additional site was similarly treated with the exception of test substance and acted as a control.
For exposures of one hour or more each treatment site was covered with cotton wool and "Tubigrip" elasticated bandage dressing for the duration of the exposure period. The animals were returned to their cages immediately after treatment.
REMOVAL OF TEST SUBSTANCE
- Washing (if done): Treatment site was washed with lukewarm water (30-40°C) to remove any residual test substance. The treated area was blotted dry with absorbent paper.
- Time after start of exposure: At the end of the exposure period

- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied (volume or weight with unit):0.1 ml of the test substance, weighing approximately 85 mg, was instilled into the right eye by pulling the lower eyelid away from the eye ball to form a cup into which the test substance was dropped. The eyelids were then gently held together for one second before releasing; the left eye remained untreated. The untreated eye was used as a comparison with the treated eye during assessment of ocular lesions. - Duration of treatment / exposure:
- Not applicable
- Observation period (in vivo):
- Ocular reactions to treatment were assessed 1, 24, 48 and 72 hours after treatment.
- Number of animals or in vitro replicates:
- 3 female rabbits
- Details on study design:
- The eyes of each animal were examined prior to instillation of the test substance to ensure that there was no pre-existing corneal damage, iridial inflammation or conjunctival irritation. A sentinel animal was used in this study with two additional animals.
SCORING SYSTEM: Draize scoring system
TOOL USED TO ASSESS SCORE: An ophthalmoscope or pencil beam torch was available for use to facilitate inspection of the eyes.
OBSERVATIONS:
Clinical signs: The behaviour of each rabbit was observed immediately following instillation of the test substance to allow assessment of the initial pain response (for criteria for assessment of pain response see "Any other information on materials and methods incl. tables" below).
The animals were checked at least twice during the first hour after dosing and at regular intervals throughout the day to ensure no severe injury passed unnoticed.
