Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 406 (Skin Sensitisation)
- Deviations:
- no
- GLP compliance:
- yes
- Type of study:
- guinea pig maximisation test
- Justification for non-LLNA method:
- In recently published articles in peer reviewed journals, it is clearly demonstrated that surfactants are more likely to give rise to false positives in the LLNA.
Consequently, in the evaluation of such substances for sensitizing properties the LLNA test is not an appropriate assay and would not represent an optimum use of test animals. It is therefore recommended that the Guinea Pig Maximisation Test (GPMT) is used instead. This is also supported by the TG OECD 406 " In addition, test substance classes or substances containing functional groups shown to act as potential con founders (Basketter et al., 2009) may necessitate the use of guinea pig tests".

- Executive summary:
At the request of CECA SA, Paris-la-Défense, France, the potential of the test item DINORAMOX S3 (batch No. 6751) to induce delayed contact hypersensitivity was evaluated in guinea pigs according to the maximization method of Magnusson and Kligman and to OECD (No. 406, 17th July 1992) and EC (96/54/EEC, B.6, 30 July 1996) guidelines.
The study was conducted in compliance with the principles of Good Laboratory Practice Regulations.
Methods
Thirty guinea pigs were allocated to two groups: a control group of five males and five females and a treated group of ten males and ten females.
On day 1, three pairs of intradermal injections were performed in the interscapular region of all animals:
- Freund's complete adjuvant (FCA) diluted to 50% (v/v) with 0.9% NaCl (both groups),
- test item at the concentration of 0.1% in corn oil (treated group) or vehicle alone (control group),
- test item at the concentration of 0.1% in a mixture FCA/0.9% NaCl (50/50, w/w) (treated group) or vehicle at the concentration of 50% (v/w) in a mixture FCA/0.9% NaCl (50/50, v/v) (control group).
On day 8, the animals of the treated group received a topical application of the test item at the concentration of 25% (w/w) in ethanol/water (80/20) to the same test site, which was then covered by an occlusive dressing for 48 hours. The animals of the control group received an application of the vehicle under the same experimental conditions.
On day 22, all animals of both groups were challenged by a cutaneous application of the test item at the concentration of 5% (w/w) in acetone to the right flank. The test item was maintained under an occlusive dressing for 24 hours. The vehicle was applied to the left flank under the same experimental conditions.
Skin reactions were evaluated approximately 24 and 48 hours after removal of the dressing.
At the end of the study, animals were killed without examination of internal organs.
Results
No systemic clinical signs and no deaths related to treatment were noted during the study.
After the challenge application, no cutaneous reactions were observed in the animals of the control group.
In the treated group, at the 24-hour reading, a discrete erythema was noted in 5/19 animals. At the 48-hour reading, a discrete or moderate erythema was recorded in 3/19 and 2/19 animals, respectively. Dryness of the skin, which masked the evaluation of the erythema in one animal, was also observed in 5/19 animals at the 48-hour reading.
The cutaneous reactions observed at the 48-hour reading in 5/19 animals of the treated group were attributed to delayed contact hypersensitivity.
Conclusion
Under our experimental conditions and according to the maximization method of Magnusson and Kligman, the test item DINORAMOX S3 (batch No. 6751) induces delayed contact hypersensitivity in 5/19 (26%) guinea pigs and therefore should be considered as a mild sensitizer.
However, according to the classification criteria laid down in Council Directive 67/548/EEC (and subsequent adaptations), the test item should not be considered as a skin sensitizer.
