- Executive summary:
The evaluation of the delayed cutaneous hypersensitivity of the test article was performed, according to the OECD Guideline 406 (Skin Sensitisation) under GLP-conditions, in albino Hartley guinea-pigs. 30 animals of both sexes were used, one control group of 10 animals (induction: vehicle - challenge: test article) and one treated group of 20 animals (induction and challenge: test article) were used. The applications corresponding to "induction" were performed as follows:
Treated group:
*By intradermal route: 3 series of 2 x 0.1 ml injections
- Freund's complete adjuvant at 50 % (V/V) in an isotonic injectable solution;
- test article in a 0.1 % (W/W) solution in sterile Codex liquid paraffin;
- mixture 50/50 (V/V): test article in a 0.2 % (W/W) suspension in sterile Codex liquid paraffin
+ Freund's complete adjuvant at 50 % (V/V) in an isotonic injectable solution, i.e. a final 0.1 % concentration of the test article.
Injection of the test article in a 0.1 % solution provoked a weak to moderate irritation during the preliminary study.
*By topical occlusive route for 48 hours, with 0.5 ml of the test article as supplied.
As this application provoked a weak to moderate irritation during the preliminary study, no skin painting was performed on Day 8, with 0.5 ml of sodium lauryl sulphate at 10 % (W/W) in Codex paraffin.
Control group :
The intradermal injections and the topical occlusive application for 48 hours were carried out under the same conditions as in the treated group, sterile Codex liquid paraffin replacing the test article.
- The rest period was 11 days without treatment.
- During the "challenge", topical occlusive application for 24 hours was performed in the treated group and in the control group with the test article as supplied and at the dose level of 0.5 ml (Maximum Non-Irritant Concentration: M.N.I.C). The vehicle was also applied during the challenge. The cutaneous macroscopic examinations were performed according to the Magnusson & Kligman scale and to the challenge application sites, 24 and 48 hours after removal of the patches. Histopathologicai examinations of the skin were performed for 4 animals of the treated group which showed doubtful macroscopic reactions at 24 hours.
RESULTS AND CONCLUSION:
- No signs of systemic toxicity and no influence on body weights were noted.
- Signs of irritation were noted during induction after application of the test article in the treated group.
- The macroscopic and histopathologicai examinations revealed pathological lesions of delayed hypersensitivity in 17 out of the 20 treated animals. No cutaneous abnormality was noted in the 9 guinea-pigs examined in the control group. From the results obtained under the experimental conditions employed, the test article provoked a reaction of cutaneous sensitization in 85 % of the animals examined. In conclusion, FAT 92267/A is sensitizing to the guinea pig skin.
