In vivo test system
Test animals
- Species:
- mouse
- Strain:
- NMRI
- Sex:
- female
Study design: in vivo (LLNA)
- Vehicle:
- acetone/olive oil (4:1 v/v)
- Concentration:
- Test item: 0 % (vehicle control), 2 %, 10 % and 50 %.
Positive control: 40 % Alpha Hexyl Cinnamic Aldehyde - No. of animals per dose:
- The modified Local Lymph Node Assay (IMDS) was performed on 24 female NMRI mice of the strain HsdWin:NMRI (6 animals/test item group and 6 control animals) to determine if there is any specific (sensitizing) or non-specific (irritant) stimulating potential of the test item N-Phenyl-N-[(trichloromethyl)thio ]benzenesulphonamide. A concurrent control of 6 animals treated with Alpha Hexyl Cinnamic Aldehyde was included.

Any other information on results incl. tables
Compared to vehicle treated animals there were clear increases in weights of the draining lymph nodes and in the cell counts at all dose groups. These changes are of statistical significance. The "positive level" of index 1.4 [6, 8, 9] was exceeded for the cell counts in all
dose groups.
The "positive level" of ear swelling which is 2x 10·2 mm increase [8, 9], i.e. about 10% of the control values, has been exceeded in all dose groups (Appendix 11.2.2.). These changes are of statistical significance. A significant increase compared to vehicle treated animals regarding ear weights was detected in all dose groups as well. An increase in these parameters would point to an acute irritating (inflammatory) response. However, such an irritant property could also be combined with a strong skin sensitizing
potential of a test compound.
In conclusion, these results show that the test item N-Phenyl-N[( trichloromethyl)thio]benzenesulphonamide has a strong sensitizing potential in mice after dermal application of a 2 % concentration. Although it is not possible to calculate an exact EC value from the data obtained, it is clear that the EC value is in any case below 1%.
