- Pretest
For detecting a possible influence on irritating effects of previous intradermal treatment with Freund's adjuvant, animals pretreated with Freund's adjuvant / 0.9% aqueous NaCl-solution (1 : 1) each, in the same manner as intradermal induction about 3 weeks prior to the application of the test substance were used. In the preliminary test after two 24-hour percutaneous occlusive applications within 96 hours the minimum irritant concentratian was found to be a 50% test substance preparation in olive oil DAB 9 and the maximum non-irritant concentration a 25% test substance preparation in olive oil DAB 9 (48 hours after the beginning of application).
Applicability: it was possible to inject a 5% test substance preparation in olive oil DAB 9 resp. in Freund's adjuvant / 0.9%. aqueous NaCl-salution (1 :1) with a syringe.
INTRADERMAL induction: 13 intradermal injections in groups of two per animal
Injections for the test group:
A) front row: 2 injections each of 0.1 ml Freund's adjuvant without test substance emulsified with 0.9% aqueous NaCl-solution in a ratio of 1 :1.
B) middle row: 2 injections each of 0.1 ml of the test substance formulation.
C) back row: 2 injections each of 0.1 ml Freund's adjuvant / 0.9% aqueous NaCl-solution (1 :1) with test substance.
Injections for control groups 1 and 2: The animals were given the same injections but without test substance, only with the formulating agent.
Site of application: shoulder.
Readings: about 24 h and 48 h after the beginning of application.
Percutaneous induction was carried out one week after intradermal induction.
Amount applied: 2 x 4 cm filter paper strips were applied to the skin of the shoulder under an occlusive dressing (the bandage consist of rubberized linenpatches 4 x 4 cm from Russka and Fixomull Stretch (adhesive fleece) from Beiersdorf AG). In the case of liquids the filter paper strip was soaked in the test substance formulation; thus, the animals were exposed to about 0.3 g of the test substance formulation. The control groups were treated analogously to the test group but only with the solvent without the test substance.
Duration of exposure: 48 hours. Site of application: shoulder, same area as in the case of the previous intradermal application. Readings: 48 h after the beginning of application.
Assessment of the skin findings: according to Draize, 1959 (analogous to the pretest)
CHALLENGE
Test concentration: maximum non-irritant concentration. Challenge 21 days after intradermal induction.
Amount applied: 2 x 2 cm filter paper strips were applied to the skin of the flank under an occlusive dressing (the bandage consist of rubberized linenpatches 4 x 4 cm from Russka and Fixomull Stretch (adhesive fleece) from Beiersdorf AG). In the case of liquids the test filter paper strip was soaked in the test substance formulation; thus the animals were exposed to about 0.15 g of the test substance formulation.
Challenge: treatment of the test group and of control group 1 with the test substance formulation. Additionally olive oil DAB 9 was applied as a vehicle. Control group 2 only received olive oil DAB 9.
Duration of exposure: 24 hours. Site of application: intact clipped flank. Readings: 24 and 48 h after the removal of the patch. Assessment of skin findings: according to Draize, 1959 (analogous to the pretest) - Positive control substance(s):
- yes
- Remarks:
- 1-chlor-2,4-dinitro-benzol
Results and discussion
- Positive control results:
- Reading 24 hours after the challenge with 1% of the positive control substance in ethanol in postive skin reaction was observed in 10/10 tested animals.

Any other information on results incl. tables
One animal of the test group died after percutaneous induction.
Observation after intradermal induction:
Well-defined erythema and slight edema were observed at the injection sites of the control and test animals, at which only Freund's adjuvant/0.9% aqueous NaCl-solution (1:1) was applied.
Injection of the test substance in olive oil DAB 9 resp. in Freund's adjuvant/0.9%/ aqueous NaCl-solution (1 :1) caused well-defined erythema and slight edema in the test animals. The control animals injected with olive oil DAB 9 (vehicle) showed well-defined erythema.
Observation after percutaneous induction:
Incrustation partially open (caused by the intradermal induction) in addition to well-defined erythema and slight edema were observed in the test and control animals.
