- Source: Japan SLC Inc., Shizuoka, Japan),
- Age at study initiation: 6-8 weeks old
Study design: in vivo (LLNA)
- Vehicle:
- other: 20% ethanol
- Concentration:
- 25 microliters of 10% test chemical
- No. of animals per dose:
- 3
- Details on study design:
- TREATMENT PREPARATION AND ADMINISTRATION:
Groups of mice (n=3) were treated with the indicated concentrations of metal salts or vehicle (20% ethanol
solution) by applying 25microliters to the dorsum of both ears for three consecutive days. Prior to the test chemicals
treatment, the ears of each mouse were gently abraded using a 19-g needle. Four days following the initial application, draining lymph nodes were excised. A single cell suspension of LNC was prepared and incorporation of [3H]TdR was measured. - Positive control substance(s):
- not specified
- Statistics:
- The incorporation of [3H]TdR was measured using a liquid scintillation counter and expressed as mean counts per min (cpm) + standard deviation per node of three animals for each test group. Increases in [3H]TdR incorporation relative to vehicle-treated controls were calculated for each test group and expressed as stimulation indices (SI).

- Parameter:
- SI
- Value:
- 0.82
- Test group / Remarks:
- test group
- Remarks on result:
- other: no reactions observed
- Cellular proliferation data / Observations:
- CELLULAR PROLIFERATION DATA/observation
CELLULAR PROLIFERATION DATA: [3H]TdR incorporation
(mean cpm ± SD (x 10-3)) = 1.26 + 0.08
Applicant's summary and conclusion
- Interpretation of results:
- other: not sensitizing
- Conclusions:
- The SI value of the test chemical was 0.82. Since the SI value was below 3, EC3 value couldnot be calculated. Hence, the test chemical was considered to be not sensitizing to skin
- Executive summary:
LLNA was performed to evaluate the contact sensitivity of the test chemical.
Groups of female BALB/c mice (n=3) were treated with 10% of the test chemical in 20% ethanol or ethanol alone by applying 25 microliters to the dorsum of both ears for three consecutive days. Four days following the initial application, draining lymph nodes were excised. A single cell suspension of LNC was prepared. Incorporation of [3H]TdR was measured, and recorded as mean cpm ± standard deviation (SD) per node of three mice for each group.The incorporation of [3H]TdR was measured using a liquid scintillation counter and expressed as mean counts per
min (cpm) + standard deviation per node of three animals for each test group. Increases in [3H]TdR incorporation relative to vehicle-treated controls were calculated
for each test group and expressed as stimulation indices (SI).
The SI value of the test chemical was 0.82. Since the SI value was below 3, EC3 value couldnot be calculated. Hence, the test chemical as considered to be not sensitizing to skin
