- [S9 fraction]
Species : Rat
Sex : Male
Strain : Sprague-Dawley
Supplier : Molecular Toxicology, Inc.
Storage condition : Freeze(-15 °C below)
Product No. : 11-01L
Lot No. : 4365
Inductive material : Aroclor 1254-induced rat liver S-9
[S9 cofactor]
Name : Cofactor Ⅰ
Manufacturer : Genogen Co., Ltd.
Lot No. : 201215-I, 210203-I
Storage condition : Deep freeze(-70±20 °C) - Test concentrations with justification for top dose:
- Dose levels: 6.9, 20.6, 61.7, 185.2, 555.6, 1666.7 and 5000 μg/plate
In result of dose range finding study, turbidity and precipitation of test substance were not observed at all dose in the all strains in the treatment mixture. Also, when revertants were counted at the end of the incubation period, precipitation was not observed at all dose in the all strains. There was no cytotoxicity or increases in mean number of revertants at all dose in the all strains both in the presence and absence of the metabolic activation system.
In the positive control group, increases of mean number of revertant was observed more than twice compared to the negative control group.
According to results of dose range finding study, the highest dose in the main study was selected as 5000 μg/plate and serially diluted to consist of five dose levels(61.7, 185.2, 555.6, 1666.7 and 5000 μg/plate) by the common ratio of 3. - Vehicle / solvent:
- Dimethyl sulfoxide(DMSO)
Controls
- Negative solvent / vehicle controls:
- yes
- Remarks:
- Dimethyl sulfoxide(DMSO)
- Positive controls:
- yes
- Positive control substance:
- 2-acetylaminofluorene
- 9-aminoacridine
- 2-nitrofluorene
- sodium azide
- benzo(a)pyrene
- other: N-Methyl-N’-nitro-N-nitrosoguanidine
- Evaluation criteria:
- If the test substance meets the following criteria, it was judged as negative.
- When there is no dose-dependent increase of mean number of revertants in the test substance-treated group and mean number of revertants is less than 2 times the number of negative control group.
If the test substance meets all the following criteria, it was judged to be positive.
Regardless of the application of the metabolic activation system to the test substance exposure, the test substance was judged to induce a reverse mutation in the bacteria strains when the following results are obtained in at least one strain. At this time, biological relevance was considered.
- When there is dose-dependent increase of mean number of revertants in the test substance-treated group.
- When mean number of revertants in the test substance-treated group is 2 times or more than the number of revertants in negative control group at one or more dose.

Applicant's summary and conclusion
- Conclusions:
- All validity criteria of this test were fulfilled. No increases in mean number of revertants were observed at all dose in the all strains both in the presence and absence of the metabolic activation system compared to the negative control group.
In conclusion, the test substance, FCCA-04, was considered as not having reverse mutagenic potential on bacterial strains under the present study conditions.
