Environmental conditions [Rabbit room No. 2]
The animal room environment was controlled as follows : [temperature (20 ± 3) ℃,relative humidity (50 ± 20) %, the rate of air exchange was (10 ~ 15) times per hourand lighting was automatically controlled to provide 12 hours of artificial light (08:00 ~20:00 hours, 150 ~ 300 Lux)]. The feed and water were supplied for acclimation and test period.
Environmental monitoring
The temperatures and relative humidities were automatically monitored every 30 minutes by a computerized system. The luminous intensity, ammonia concentration and noise of animal room were measured once per quarter periodically. The environmental conditions were considered not to have affected the purpose or integrity of the study.
Housing
Each animal was housed individually in stainless steel cages [380(W) ㎜ × 480(D) ㎜ ×300(H) ㎜, Jeongdo Ltd., Korea].
Feed and water
The animals were fed pellet diet for rabbit (Cargill Agri Purina, Inc., 56-4, Soryong-dong, Gunsan-si, Jeollabuk-do, Korea) and given the filtered and UV irradiated water ad libitum .
Contaminant confirmation of feed and water
The diet was considered not to contain any contaminant based on the periodical analysis results report of manufacturer and water did not contain any contaminant based on periodical analysis in accordance with the SOP of Korea Testing & Research Institute.
Test system
- Vehicle:
- unchanged (no vehicle)
- Amount / concentration applied:
- 0.1 mL/animal
- Duration of treatment / exposure:
- -
- Observation period (in vivo):
- 72hrs
- Number of animals or in vitro replicates:
- 4
- Details on study design:
- The test substance was applied as a volume of 0.1 mL/animal, the dose specified in the test guidelines for test substances. The eyes of the animals were examined one day prior to test substance administration. On the day of treatment, the test substance was applied to the conjunctival sac of the left eye of each animal after gently pulling the lower lid away from the eyeball. The lids were then gently held together for about one second to prevent loss of test substance. The right eye wasremained untreated and served as the reference control.
A single animal was treated first. As neither a corrosive effect nor a severe irritant effect were observed after the examinations, the test was confirmed by using the three remaining animals.

Applicant's summary and conclusion
- Conclusions:
- The present study, to investigate the eye irritation/corrosion of MIRAMER M1086, was conducted with NZW rabbits. After application of test substance 0.1 g in the eye of rabbit, parameters measured during 72 hours observation period were mortality, clinical signs, body weight changes and local irritation for 72 hours after application of test substance.
No mortality was observed in the present study and no treatment-related clinical signs were observed in any treated animals. All tested animals showed normal gains in body weight. After application of test substance, eye irritation was observed as conjunctiva redness and chemosis. But the results of the observed sign were restored within 48 hours.
National Institute of Environmental Research (NIER) Notification No. 2010-25 (August 27, 2010), Korea and Globally Harmonized System of Classification and Labelling of Chemicals (GHS), test substance would not be classified as an dermal irritant.
Based on these results, the test substance (MIRAMER M1086) was considered to be mildly irritating substance in this study. Eye irritation was considered slight and reversible reaction. - Executive summary:
