Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: OECD 474
- Deviations:
- no
- Principles of method if other than guideline:
- Test procedure:
C3RO was given at doses of 5, 25, and 50 mg/kg to groups of
7 male Wistar Han rats, approximately 9 to 10 weeks old at
dosing; two groups of 7 control rats were given the vehicle
alone. Male rats only were used because there was no data to
indicate a sex difference in response to the toxicity of
C3RO. A group of 3 rats was given the positive control
cyclophosphamide, at 20 mg/kg.
Vehicle: 1% Carboxymethylcellulose / 0.1% Tween 80 in
purified water
Strain: Wistar Hanover, substrain AlpkHsdBrlHan:WIST
Positive control: Cyclophosphamide 2 mg/l in purified water - GLP compliance:
- yes

Results and discussion
- Details on results:
- C3RO induced a statistically and biologically significant
increase in micronucleated immature erythrocytes (MIE) in
the bone marrow of male Wistar Han rats after a single oral
dose of 25 mg/kg, no increase in MIE was seen with 5 mg/kg.
There was no evidence of bone marrow toxicity as the
immature erythrocytes:mature erythrocytes (IE:E) ratio was
similar in the treated and vehicle control groups at both
sampling times.
It was concluded that, 25 mg/kg of C3RO induced a
statistically significant level of micronucleated immature
erythrocytes in the bone marrow of male Wistar Han rats.
Applicant's summary and conclusion
- Conclusions:
- It was concluded that, 25 mg/kg of C3RO induced a
statistically significant level of micronucleated immature
erythrocytes in the bone marrow of male Wistar Han rats.
