MAIN STUDY
A. INDUCTION EXPOSURE
Approximately 24 hours prior to the epidermal application the test area was pre-treated with 10 % Sodium-Lauryl-Sulfat (SLS) in petrolatum-oil, because no primary irritation concentration could be determined in the corresponding pre-test. The SLS was massaged into the skin with a glass rod without bandaging. This SLS-concentration enhances sensitization by provoking a mild inflammatory reaction.
- No. of exposures: Three pairs of intradermal injections; 2 x 4 cm patch of filter paper (saturated with the test article)
- Exposure period: 48 h (occulsive)
- Test groups:
- Control group: The guinea-pigs of the control group were treated with the omission of test article.
- Site: dorsal skin from the scapular region
- Frequency of applications: Three pairs of intradermal injections, once occulsive patch
- Duration: 48 hrs
B. CHALLENGE EXPOSURE
- No. of exposures: once
- Day(s) of challenge: guinea-pigs were challenged two weeks after the epidermal induction application
- Exposure period: 24 hrs
- Test groups:
- Control group: The control animals were treated in the same way
- Site: left and right flank
- Evaluation (hr after challenge): The sites were assessed for erythema and edema immediately, 24 and 48 hours after removal of the dressing,
using the numerical scoring system as described under preliminary study
- Challenge controls:
- yes, 25% of the substance applied
- Positive control substance(s):
- yes
- Remarks:
- HCHO
Study design: in vivo (LLNA)
- Statistics:
- Fisher-Test (The Exact Fisher Test for comparison of the basic probability of two binomial distributions. L. Sachs, Statistische Auswertungsmethoden, Georg Thieme Verlag, Stuttgart 1971).
For calculation of p-values the 24-hour reading of the animals from the control and test group was used.
