Test animals / tissue source
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or tissues and environmental conditions:
- TEST ANIMALS
- Source: Centre Lago S. A., 01540 Vonnas, France
- Age at study initiation: ca. 6 months
- Weight at study initiation: 0: 3.60 kg – 3.70 kg
- Housing: Single housing in stainless steel wire mesh cages with grating, floor area: 3000 cm2.
- Diet (e.g. ad libitum): Kliba-Labordiaet (Kaninchen & Meerschweinchenhaltung “GLP”), Provimi Kliba SA, Kaiseraugst, Basel, Switzerland (about 130 g/animal per day)
- Water (e.g. ad libitum): ad libitum, Tap water
- Acclimation period: at least 5 days before application
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 20 – 24°C
- Humidity (%): 30 – 70%
- Photoperiod (hrs dark / hrs light): 12/12
Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other: untreated eye of the same animal
- Amount / concentration applied:
- 0.1 mL bulk volume (about 74 mg) of the undiluted semi-solid test substance
The solid test substance was heated at about 85°C for better handling. Before application, the test substance was cooled down to body temperature. At this temperature the test substance was semi-solid and could be applied with a sharp spoon. - Duration of treatment / exposure:
- 24 hours
- Observation period (in vivo):
- 7 days
- Number of animals or in vitro replicates:
- 3
- Details on study design:
- Single instillation into the conjunctival sac of the right eyelid.
About 24 hours after application of the test substance the treated eye of the animals was rinsed with 3 to 6 mL of hand-warm tap water for 1 to 2 minutes using a syringe with a blunt probe.
Readings: Approx. 1, 24, 48 and 72 h after application and then in weekly intervals maximally up to day 28.
Body weight determination just before application of the test substance and after the last reading.
A check for any dead or moribund animal was made twice each workday (at the beginning and end of work) and once daily at weekends and on public holidays.
