- No. of animals per sex per dose:
- 6
- Control animals:
- yes, concurrent vehicle
- Positive control(s):
- Mitomycin C (0,5 mg/kg bw)
Examinations
- Tissues and cell types examined:
- 2,000 polychromatic erythrocytes of bone marrow (PCEs, reticulocytes; immature erythrocytes) were scored per animal for the frequency of micronucleated cells in each of the 6 animals per dosage group
- Details of tissue and slide preparation:
- Bone marrow cells were obtained from the femurs immediately following sacrifice.
- Evaluation criteria:
- Cells were considered to be micronucleated when they neatly contained defined chromatin corpuscles with a diameter of less than one-third the diameter of the cell nucleus and stained equal or lighter than the nucleus of the cell from which the micronucleated cell was developed with a DNA specific fluorescence dye.
- Statistics:
- The experimental and control micronucleus frequency within and between the different dose groups were compared with the One Way ANOVA test and the Kruskal-Wallis tests (α=0.05).
