DETERMINATION OF CYTOTOXICITY
- Method: other: reduction of background lawn - Evaluation criteria:
- The assay was considered valid if the following criteria were met:
1. the negative control counts fell within the historical ranges.
2. the positive control chemicals induced clear increases in revertant numbers confirming discrimination between different strains, and an active S-9
preparation
3. no more than 5% of the plates were lost through contamination or some other unforeseen event.
The test article was considered to be mutagenic in this assay if:
1. the assay is valid (see above)
2. Dunnett's test gives a significant response (p ? 0.01) and the data set(s) shows a significant dose correlation - Statistics:
- Individual plate counts from all experiments were recorded separately and the mean and standard deviation of the plate counts for each treatment were determined. Control counts were compared with historical controls. Dunnett's test was used to compare the counts at each concentration with the control. The presence a concentration response was checked by non-statistical analysis, up to limiting levels (for example toxicity, precipitation or 5000 μg/plate).

RANGE-FINDING/SCREENING STUDIES:
An initial toxicity Range-Finder Experiment was carried out ± S9 in strain TA100 only, using final test substance concentrations of 1.6, 8, 40, 200, 1000 and 5000 μg/plate, plus negative (vehicle) and positive controls. Following these treatments, no evidence of toxicity was observed. Strain TA100 was included in Experiment 1 to investigate an increase in revertant numbers observed.
COMPARISON WITH HISTORICAL CONTROL DATA:
The mean numbers of revertant colonies on negative control plates all fell within acceptable historical ranges, and were significantly elevated by positive control treatments. One experiment in one strain showing variations was repeated.
