- TREATMENT AND SAMPLING TIMES ( in addition to information in specific fields): Groups, each of seven mice, were dosed once only via the intraperitoneal route with the test material at 200, 100 or 50 mg/kg. One group of mice from each dose level was killed by cervical dislocation 24 hours following treatment and a second group dosed with test material at 200 mg/kg was killed after 48 hours. In addition, three further groups of mice were included in the study; two groups (seven mice) were dosed via the intraperitoneal route with the vehicle alone (distilled water) and a third group (five mice) was dosed orally with cyclophosphamide. The vehicle controls were killed 24 or 48 hours following dosing and positive control group animals were killed 24 hours following dosing.
DETAILS OF SLIDE PREPARATION: Immediately following termination (i.e. 24 or 48 hours following dosing), both femurs were dissected from each animal, aspirated with foetal calf serum and bone marrow smears prepared following centrifugation and re-suspension. The smears were air-dried, fixed in absolute methanol, stained in May-Grünwald/Giemsa, allowed to air-dry and a cover slip applied using mounting medium.
METHOD OF ANALYSIS: Stained bone marrow smears were coded and examined blind using light microscopy at x1000 magnification. The incidence of micronucleated cells per 2000 polychromatic erythrocytes (PCE-blue stained immature cells) per animal was scored. Micronuclei are normally circular in shape, although occasionally they may be oval or half-moon shaped, and have a sharp contour with even staining. In addition, the number of normochromatic erythrocytes (NCE-pink stained mature cells) associated with 1000 erythrocytes was counted; these cells were also scored for incidence of micronuclei.
The ratio of polychromatic to normochromatic erythrocytes was calculated together with appropriate group mean values and standard deviations. - Evaluation criteria:
- A comparison was made between the number of micronucleated polychromatic erythrocytes occurring in each of the test material groups and the number occurring in the corresponding vehicle control group.
A positive mutagenic response was demonstrated when a statistically significant, dose responsive, toxicologically relevant increase in the number of micronucleated polychromatic erythrocytes was observed for either the 24 or 48-hour kill times when compared to their corresponding control group.
If these criteria were not fulfilled, then the test material was considered to be non-genotoxic under the conditions of the test.
A positive response for bone marrow toxicity was demonstrated when the dose group mean polychromatic to normochromatic ratio was shown to be statistically significantly lower than the concurrent vehicle control group.
All data were statistically analysed using appropriate statistical methods as recommended by the UKEMS Sub-committee on Guidelines for Mutagenicity Testing Report, Part III (1989). The data was analysed following a √(x +1) transformation using Student's t-test (two tailed) and any significant results were confirmed using the one way analysis of variance.

Insufficient evidence of toxicity was observed in animals dosed with test material via the oral route and, therefore systemic absorption could not be confirmed using this dose route.
In animals dosed with the test material via the intraperitoneal route premature deaths occurred at and above 500mg/kg, and clinical signs were observed at and above200 mg/kg as follows: Hunched posture, ptosis, extremities blue in colour, faeces stained blue, urine stained blue, ataxia, tiptoe gait and diarrhoea.
The test material showed no marked difference in its toxicity to male or female mice; it was therefore considered to be acceptable to use males only for the main test. Adequate evidence of test material toxicity was demonstrated via the intraperitoneal route of administration; therefore, this was selected for use in the main test. The maximum tolerated dose (MTD) of the test material, 200 mg/kg, was selected for use in the main test, with 100 and 50 mg/kg as the lower dose levels.

Mortality Data and Clinical Observations
There were no premature deaths seen in any of the dose groups. Clinical signs were observed in animals dosed with the test material at and above 50 mg/kg in both the 24 and 48-hour groups where applicable, these were as follows: Hunched posture, ano-genital area stained blue, fur stained blue, extremities blue in colour, faeces stained blue and urine stained blue.

Individual and group mean data are presented in Tables 2 to 8 found in Attachment 1 below.
A modest but statistically significant decrease in the PCE/NCE ratio was observed in the 24-hour 200 mg/kg test material dose group when compared to the concurrent control groups. This decrease, together with the observation of clinical signs in both the 24 and 48-hour test material dose groups, was taken to indicate that systemic absorption had occurred and exposure to the target tissue had been achieved.
There was no statistically significant increase in the frequency of micronucleated PCE in the 48-hour 200 mg/kg test material dose group. Very modest but statistically increases in the frequency of micronucleated PCE were observed in the 24-hour 100 and 50 mg/kg dose groups. However, there was no evidence of a statistically significant increase in the 24-hour 200 mg/kg dose group, the group means of micronucleated PCE were within the acceptable range for vehicle controls, and the statistical significance was considered to be due to the comparison to the very low concurrent vehicle control group mean. Therefore, the responses were considered to be spurious and of no toxicological significance.
The positive control group showed a marked increase in the incidence of micronucleated polychromatic erythrocytes hence confirming the sensitivity of the system to the known mutagenic activity of cyclophosphamide under the conditions of the test.
The test material was found not to produce a toxicologically significant increase in the frequency of micronuclei in polychromatic erythrocytes of mice under the conditions of the test.
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): negative
The test material was considered to be non-genotoxic under the conditions of the test. - Executive summary:
Introduction. The study was performed to assess the potential of the test material to produce damage to chromosomes or aneuploidy when administered to mice. The method was designed to comply with the 1997 OECD Guidelines for Testing of Chemicals No.474 "Micronucleus Test", Method B12 of Commission Regulation (EC) No. 440/2008 of 30 May 2008, the USA EPA, TSCA and FIFRA guidelines and the Japanese METI/MHLW guidelines for testing of new chemical substances.
Methods. A range-finding test was performed to find suitable dose levels of the test material, route of administration and to investigate to see if there was a marked difference in toxic response between the sexes. There was no marked difference in toxicity of the test material between the sexes; therefore the main test was performed using only male mice. The micronucleus test was conducted using the intraperitoneal route in groups of seven mice (males) at the maximum tolerated dose (MTD) 200 mg/kg and with 100 and 50 mg/kg as the two lower dose levels. Animals were killed 24 or 48 hours later, the bone marrow extracted, and smear preparations made and stained. Polychromatic (PCE) and normochromatic (NCE) erythrocytes were scored for the presence of micronuclei.
Further groups, each of 7 mice, were given a single intraperitoneal dose of distilled water or dosed orally with cyclophosphamide (5 mice), to serve as vehicle and positive controls respectively. Vehicle control animals were killed 24 or 48 hours later, and positive control animals were killed after 24 hours.
Results. There were no premature deaths seen in any of the dose groups. Clinical signs were observed in animals dosed with the test material at and above 50 mg/kg in both the 24 and 48-hour groups where applicable, these were as follows: Hunched posture, ano-genital area stained blue, fur stained blue, extremities blue in colour, faeces stained blue and urine stained blue.
A modest but statistically significant decrease in the PCE/NCE ratio was observed in the 24-hour 200 mg/kg test material dose group when compared to the concurrent control groups. This decrease, together with the observation of clinical signs in both the 24 and 48-hour test material dose groups, was taken to indicate that systemic absorption had occurred and exposure to the target tissue had been achieved.
There was no statistically significant increase in the frequency of micronucleated PCE in the 48-hour 200 mg/kg test material dose group. Very modest but statistically increases in the frequency of micronucleated PCE were observed in the 24-hour 100 and 50 mg/kg dose groups. However, there was no evidence of a statistically significant increase in the 24-hour 200 mg/kg dose group, the group means of micronucleated PCE were within the acceptable range for vehicle controls, and the statistical significance was considered to be due to the comparison to the very low concurrent vehicle control group mean. Therefore, the responses were considered to be spurious and of no toxicological significance.
The positive control group showed a marked increase in the incidence of micronucleated polychromatic erythrocytes hence confirming the sensitivity of the system to the known mutagenic activity of cyclophosphamide under the conditions of the test.
Conclusion. The test material was considered to be non-genotoxic under the conditions of the test.
