Number of animals: 20 females (nulliparous and non-pregnant), five females per group.
In the main study, three groups of five experimental animals were treated with test substance concentrations of 5%, 25% or 50% on three consecutive days, by open application on the ears. Five vehicle control animals were similarly treated, but with vehicle alone (Dimethyl sulphoxide).
Three days after the last exposure, all animals were injected with 3H-methyl thymidine and after five hours the draining (auricular) lymph nodes were excised.
After precipitating the DNA of the lymph node cells, radioactivity measurements were performed. The activity was expressed as the number of Disintegrations Per Minute (DPM) and a stimulation index was subsequently calculated for each group. - Positive control substance(s):
- other: Dimethyl Sulfoxide
Results and discussion
- Positive control results:
- The DPM values calculated was 430.
The SI values calculated was 1.0.

- Parameter:
- SI
- Remarks on result:
- other: The SI values calculated for the substance concentrations 5, 25 and 50% were 9.4, 8.9 and 12.9 respectively. These results show that the test substance elicits an SI >= 3. The EC3 value was established to be between 0 and 5%.
- Parameter:
- other: disintegrations per minute (DPM)
- Remarks on result:
- other: The DPM values calculated for the substance concentrations 5, 25 and 50% were 4038, 3835 and 5550 respectively.
