Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): negative
Under the study conditions it is concluded that HCA is neither clastogenic nor aneugenic. - Executive summary:
In an in vivo micronucleus assay (Wild et al., 1983), performed similarly to the OECD guideline No. 474 with minor deviations, male/female NMRI mice were exposed to alpha-Hexylcinnamaldehyde (HCA) diluted in olive oil by a single intraperitoneal dose. Different concentrations (324, 540, 756 mg/kg bw) were tested (8 animals per dose). 30 hours after the injection, the bone marrow cells were collected and one thousand polychromatic erythrocytes were observed in order to quantify the number of micronucleated polychromatic erythrocytes. Concurrent vehicle animals were used as negative control, no data was available on positive control.
Under the test conditions, there was no significant increase of micronucleated plychromatic erythrocytes, if compared with the concurrent control. No mortality was observed.
Therefore, under the study conditions it is concluded that HCA is neither clastogenic nor aneugenic.
