Examinations

- Details of tissue and slide preparation:
- CRITERIA FOR DOSE SELECTION: based on a dose range finding study
TREATMENT AND SAMPLING TIMES: The animals of all treatment groups received a single dose at a volume of 10 mL/kg bw
DETAILS OF SLIDE PREPARATION:
Bone marrow smears from both femurs of each animal were prepared. The slides were air-dried at least overnight and then stained with Giemsa according to modification of Gollapudi and Kamra. The slides were fixed in 100 % methanol for 5 min., then rinsed twice in bidistilled water and thereafter stained in Giemsa solution. After air -drying the back side was cleaned, necessary with ethanol and then dipped for 3 min. in xylol.
METHOD OF ANALYSIS:
From the three slides prepared per animal, one slide was chosen and randomly scored. The slides of five male and five female animals per treatment group were scored microscopically at a magnification of 1000. The number of micronucleated cells was counted in 1000 polychromatic erythrocytes/ per animal. The ratio of polychromatic to normochromatic erythrocytes was determined by counting and differentiating the first 1000 erythrocytes at the same time. Averages and standard deviations were calculated after decoding the complete scoring results. - Evaluation criteria:
- - A micronucleus test is considered acceptable if it meets the following criteria: the positive control substance induced a statistical significant increase in the frequency of micronucleated polychromatic erythrocytes- the incidence of micronuclei should reasonably fall within the historical control data range of the laboratory.
- A test item is considered positive in the micronucleus test if it induced a biologically as well as statistically significant increase (p < 0.05) in the frequency of micronuclei at any dose or at any sampling either in the male or in the female groups.
- A test substance is considered negative in the micronucleus test if none of the tested doses or sampling times showed a statistically significant (p < 0.05) increase in the incidence of micronuclei, neither in male nor in female groups. - Statistics:
- Statistical analysis of data was performed by calculating the statistical significance versus negative controls with the aid of the tables of Kastenbaum and Bowman. The preceding criteria are not absolute and other factors may influence the final evaluation decision.

- Vehicle controls validity:
- valid
- Negative controls validity:
- not examined
- Positive controls validity:
- valid
- Additional information on results:
- RESULTS OF RANGE-FINDING STUDY
- Dose range: the dose range finding study determined 5000 mg/kg bw as final concentration for the main trial.
- Clinical signs of toxicity in test animals: no further signs of toxicity were observed.
- Rationale for exposure: based on the non toxic effect in the dose range finding study.
RESULTS OF DEFINITIVE STUDY
- Induction of micronuclei: no
- Ratio of PCE/NCE: mean of animal 1 - 5 at a dose of 5000 mg/kg bw = 1.24
- Statistical evaluation: The investigated test item did not induce a statistically significant (time-dependent) increase in the number of micronucleated polychromatic erythrocytes in the bone marrow of male or female mice.
