MAIN STUDY
ANIMAL ASSIGNMENT AND TREATMENT
- Name of test method: non-radiolabelled LLNA
- Criteria used to consider a positive response: The results of the LLNA were evaluated according to the following criteria.
The following thresholds were determined by Ulrich (2007) from analysis of historical data:
Ear weight index: 1.05
LN weight: 1.2
LN cell count: 1.3
1. Values which exceed these thresholds were considered positive
- when a statistically significant increase in one of the parameters occurs and a clear
concentration-dependence can be derived
- or with no statistical significance, but a clear concentration-dependence.
2. Values which are below these thresholds were considered positive
- when a statistical significant occurs in one of the parameters together with a clear
concentration dependence.
TREATMENT PREPARATION AND ADMINISTRATION: Before start of application the suspension was mixed for 5 minutes with a
magnetic stirrer and then were still mixed during application. - Positive control substance(s):
- other: Dinitrochlorobenzene
- Statistics:
- For statistical calculations the software Statgraphic® Centurion (version XV, USA) was used. At first the global comparison of all three values of the concentration groups with vehicle control was perforrned by applying the non-parametric Kruskal-Wallis test, and then the non-parametric two-group Mann-Whitney rank test (probability level 0.05) was applied to all two-group comparisons.
