OTHER EXAMINATIONS
A preliminary toxicity test was carried out with the concentrations ranging from 0.08 to 5000 µg/plate. Thereafter, the Ames test was performed with 20, 78, 313, 1250 and 5000 µg/plate test article (with and without microsomal activation). The substance precipitated in soft agar at and above a concentration of 20 µg/plate.
MUTATION TEST
Mutation assays with and without microsomal activation were performed twice in triplicate per strain and per group (standard plate test).
Each Petri dish contained approximately 20 ml of minimum agar, 0.1 ml of the test substance or the vehicle and 0.1 ml of a bacterial culture (in nutrient broth) in 2.0 ml of soft agar. Experiments with microsomal activation contained additionally 0.5 ml of an activation mixture, consistent of S9 fraction of liver from Aroclor 1254 induced rats and co-factors. The plates were incubated for about 48 hours at 37 ± 1.5°C in darkness.
EVALUATION CRITERIA
Arithmetic mean of revertant colonies was calculated. The test substance is considered to be non-mutagenic if the colony count in relation to the negative control is not doubled at any concentration. - Statistics:
- No statistical analysis
