- Remarks on result:
- not determinable because of methodological limitations
- Remarks:
- There is no demonstration that the substance has reached the target cells.
- Additional information on results:
- Results toxicity study: in a preliminary experiment 4 animals (2 males and 2 females) were treated with 2000 mg/kg and observed for 48 hours. All the animals did not express toxic reactions.
Mutagenicity study: CPA induced 1.38 % of MN compared with the percentage of 0.075 of the animals treated with the deionised water. The test item did not induce MN in a frequency higher than the deionized water-treated animals (vehicle control). The study is considered inadequate for the evaluation as there is no demonstration that the substance has reached the target cells.
Applicant's summary and conclusion
- Conclusions:
- The study is considered inadequate for the evaluation as there is no demonstration that the substance has reached the target cells.
- Executive summary:
An in vivo mammalian erythrocyte micronucleus test was performed on NMRI mice. The test item was administered at the dose levels of 500, 1000 and 2000 mg/kg. The treatment lasted 24 hours for the 500 and 1000 mg/kg doses and 48 hours for the 2000 mg/kg dose. The test item did not induce MN in a frequency higher than the deionized water-treated animals (vehicle control). Nevertheless, the study is considered inadequate for the evaluation as there is no demonstration that the substance has reached the target cells.
