- Details on exposure:
- Tolerability test:
A preliminary test was conducted to determine the highest dosage of the test material to be applied in the mutgenicity test (Doses / Concentrations:
200, 1000 and 5000 mg/kg bw). Three groups of 4 chinese hamsters were treated with 3 different single doses. The observation period corresponded to the interval between administration and sacrifice of the animals in the mutagenicity test, plus one day. The highest dose survived by all animals was used in the second part of the tolerability test.
In the second part, the animals were treated according to the scheme used in the mutagenicity test with consecutive doses. The observation period corresponded to the interval between administration and sacrifice of the animals in the mutagenicity test, plus one day. Depending on the outcome the highest dose causing no deaths was used as the highest in the mutagenicity test.
Mutagenicity test:
The test material was administered orally to groups of 6 female and 6 male animals each. Treatment consisted of daily one application on 2 consecutive days. 24 h after the second application the animals were sacrificed. - Duration of treatment / exposure:
- 48 h
- Frequency of treatment:
- two treatments on 2 consecutive days
- Post exposure period:
- 24 h after the second application

Examinations
- Details of tissue and slide preparation:
- Bone marrow was harvested from the shafts of both femurs and homogenized. Small drops were transferred on the end of a slide and spread out. 3 h later, the slides were stained in undiluted May-Grünwald solution/water for 2 min and in Giemsa´s 40 % for 20 min. After being rinsed in methanol 55 % for 5-8 sec and washed with water, the slides were cleaned in xylene and mounted in Eukitt.
The slides of three female and three male animals each of the negative and positive control group and of the groups treated with various doses of the test material were examined. 1000 bone marrow cells each were scored per animal and the following anomalies were registered: single jolly bodies, fragments of nuclei in erythrocytes, micronuclei in leucopoietic cells and polyploid cells. - Statistics:
- The significance of difference was assessed by x2-test.
Results and discussion
Test results
- Sex:
- male/female
- Genotoxicity:
- negative
- Toxicity:
- no effects
- Vehicle controls validity:
- valid
- Negative controls validity:
- valid
- Positive controls validity:
- valid
- Additional information on results:
- In all dose groups the percentage of cells displaying anomalies of nuclei did not differ significantly from the negative control (0.1 %).
By contrast, the positive control yielded in a marked increase of the percentage of cells with anomalies (9.48 %).
