The effect of treatment with 1 µg of SMAs 12b and 11a on days −1, 4 and 5 on ear thickness was assessed following sensitisation and challenge with oxazolone. A non-sensitised control group was also included. The data are obtained from a single experiment, which is representative of two (11a) and three (12b) independent experiments. **p < 0.01, ***p < 0.001. ** and *** represent a significant difference between 12b − (Oxa + 12b) or 11a − (Oxa + 11a) treated and PBS-treated mice sensitised and challenged with oxazolone (Oxazolone). Results are expressed as ear thickness in micrometres.
