Materials and methods
Test guideline
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 405 (Acute Eye Irritation / Corrosion)
- Principles of method if other than guideline:
- This test was designed to detennine the ocular irritation potential of substances in the non-rinsed
eyes of three (3) rabbits. The procedure is a modification of that desciibed by J.H. Draize (J.H. Draize, "Deimal Toxicity", Appraisal of the Safety of Chemicals in Foods, Drugs and
Cosmetics, (The Association of Food and Drug Officials of the United States, 1959), pp. 49 - 51.). This protocol was designed to satisfy the requirements of the Japanese Ministry of Health and
Welfare. - GLP compliance:

Test animals / tissue source
- Species:
- rabbit
- Strain:
- New Zealand White
- Details on test animals or tissues and environmental conditions:
- Three (3), female, New Zealand white rabbits weighing approximately two (2) kilograms and
about three (3) months of age, were used for each test atiicle. The animals were obtained
through a suitably licensed dealer. The animals were checked carefully upon receipt for ocular
defects, diarrhea and dehydration, respiratory difficulties, postural deficiencies, and general
condition. Any animal exhibiting visible ocular defects or irritation, or poor condition, was
rejected.
The animals were acclimated for five (5) days prior to test initiation. They were individually
housed in stainless steel cages, in a temperature controlled room, with a 12 hour light/dark cycle
and identified through individual markings on the outer ear of each animal, as well as a cage
label. The room temperature was controlled to comply with Animal Welfare Regulations with an
approximate range of 65° to 15° F. The humidlity was also monitored. Diet consisted of Lab
Diet Certified Rabbit Diet #5322, at 100 grams per day per animal. Water was provided ad
libitum.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the conditions of this test, Nomcort HK-P elicited mild, reversible, conjunctival initation to the eyes of rabbits. However the effects are not sufficient for meeting the classification criteria.
- Executive summary:
Three (3) New Zealand white rabbits, free from visible ocular defects, each
received a single intraocular application of one-tenth of one milliliter (0.1 ml) of
the test article in one (1) eye. The contralateral eye, remaining untreated, served as
a control. The eyes of all animals remained unwashed for 24 hours. Observations
of corneal opacity, iritis, and conjunctivitis were recorded one (1), 24, 48, and 72
hours after treatment, and at four (4) and seven (7) days, if initation persisted. The
test article was uJed as a 20% suspension in distilled water, that had been heated at
approximately 70° C for 30 minutes. The mixture was allowed to cool prior to
dosing.
