- RANGE FINDING TESTS:
The following concentrations have been examined on separate animals for the evaluation of the primary irritant potential and the maximum subirritant concentration of the test article:
30 and 10 % in vaseline. The tested concentrations did not induce erythema reactions. 30 % was, therefore, selected for the epidermal induction application.
10 % was used as subirritant concentration for the challenge application, because highest concentrations may lead to nonspecific reactions in adjuvant treated animals (Magnusson B., Contact Dermatitis 6, 46-50, 1980).
The concentration for the intradermal injections was selected on account of the solubility of the test article in standard vehicles. Concentration: 5 %
Vehicle: sesame oil.
MAIN STUDY
A. INDUCTION EXPOSURE
The induction was a two-stage operation. First, intradermal injections (into the neck region); second, closed patch exposure over the injection sites one week later.
First Induction, intradermal application:
Three pairs of intradermal injections (0.1 ml per injection) were made simultaneously into the shaved neck of the guinea pigs as follows:
- adjuvant/saline mixture 1:1 (v/v)
- test article in sesame oil (w/v)
- test article in the adjuvant saline mixture (w/v)
Second Induction, epidermal application:
One week later the test article was incorporated in vaseline (w/w) and applied on a filterpaper patch to the neck of the animals (patch 2x4 cm; approx. 0.4 g paste per patch; occluded administration for 48 hours).
The application sites were pretreated the day before with 10 % sodium lauryl sulfate (open application).
B. CHALLENGE EXPOSURE
Two weeks after the epidermal induction application the animals were tested on the flank with the test item in vaseline (w/w) and the vehicle alone (patch 2x2 cm; approx. 0.2 g paste per patch; occluded administration for 24 hours).
A control group was treated with adjuvant and the vehicle during the induction period. During the challenge period the group was treated with the vehicle as well as with the test article (at least 10 animals) to check the maximum subirritant concentration of the test article in adjuvant treated animals. - Positive control substance(s):
- yes
- Remarks:
- 2,4-dinitrochlorobenzene, paraphenylene- diamine or potassium-dichromate
