Test animals
- Species:
- guinea pig
- Strain:
- Dunkin-Hartley
- Sex:
- male
Study design: in vivo (non-LLNA)
Inductionopen allclose all
- Route:
- intradermal and epicutaneous
- Vehicle:
- polyethylene glycol
- Concentration / amount:
- The interdermal induction of sensitization in the test group was performed in the nuchal region with a 10% dilution of the test item in PEG 300 and in an emulsion of FCA/physiological saline. The epidermal induction of sensitization was conducted for 48hours under occlusion with the test item at 50% in PEG 300 one week after the intradermal induction. The animals of the control group were intradermally induced with PEG 300 and FCA/physiological saline and epidermally induced with PEG 300 under occlusion.
Two weekd after epidermal induction the control and test animals were challenged by epidermal application of the test item at 1% in PEG 300 and PEG 300 alone under occlusive dressing.
