- PREPARATION OF DOSING SOLUTIONS:
The test substance was weighed out and thoroughly mixed with a small amount of food in a beaker. Subsequently, a premix was prepared in a BOSCH household mixer by adding an appropriate amount of food and mixing for about 3 minutes. Then corresponding amounts of food, depending on the dose group, were added to this premix in order to obtain the desired concentrations, and mixing was carried out for about 10 minutes in a GEBR. LÖDIGE laboratory mixer.
DIET PREPARATION

- Storage temperature of food: room temperature - Analytical verification of doses or concentrations:
- yes
- Details on analytical verification of doses or concentrations:
- The stability of the test substance in the diet at room temperature was proven for 4, 8 and 32 days. The homogeneous distribution of the test substance in the diet was checked in samples of the high and low concentration drawn at the beginning of the study. These analyses served also as concentration controls for low and high concentration. Further concentration control analyses were performed in samples drawn at the start of the administration period (mid concentration) and towards the end of the administration period (all concentrations).

HISTOPATHOLOGY: Yes - Statistics:
- The statistical evaluation and calculation of the data were carried out on the computer systems of the Department of Toxicology of BASF AG:
For the parameters body weight and body weight change a parametric one-way analysis of variance was done via the F-test (ANOVA). If the resulting p-values were equal or less than 0.05, a comparison of each dose group with the control group was carried out. These comparisons were performed simultaneously via DUNNETT's test for the hypothesis of equal means. If the results of this test were significant, labels (* for p < 0.05, ** for p < 0.01) were printed together with the group means in the tables. Both tests were performed two-sided.
For all clinical chemistry and hematology parameters, excepting the differential blood count, a parametric one-way analysis of variance was done via the F-test (ANOVA). If the resulting p-value was equal or less than 0.05, a comparison of each dose group with the control group was carried out. These comparisons were performed simultaneously via DUNNETT's test for the hypothesis of equal means. If the results of this test were significant, labels (* for p < 0.05, ** for p < 0.01) were printed together with the group means in the tables. Both tests were performed two-sided.
With the exception of volume, color, turbidity, pH and specific gravity the scale for the urine parameters is divided into 4 sections (0, 1, 2, 3). For the parameter "Nitrite" only a division in two sections (0, 1) is made. The parameters were sorted into 2 classes. This was done for the statistical analysis. A pairwise comparison of each dose group with the control was carried out using FISHER's exact test for the hypothesis of equal proportions. If the results of this test are significant, labels (* for p < 0.05, ** for p < 0.01) were printed in the tables.
Results and discussion
Results of examinations
- Clinical signs:
- no effects observed
- Mortality:
- no mortality observed
- Body weight and weight changes:
- effects observed, treatment-related
- Description (incidence and severity):
- - 15000 ppm: the body weight values of the high dose group were slightly decreased in comparison to the control values. At the end of the administration period values of body weight were 6% below controls in males and 8% below controls in females. Although statistically significant only in females on days 63 to 91, the effects in both sexes were assessed as being substance-related. Corresponding body weight change values at the end of the administration period were 11% below controls in males and 17% below controls in females. Statistical significance was obtained for males on day 7 and for females on several days from day 42 onwards. This was assessed as being substance-related.

- Description (incidence and severity):
- - 15000 ppm: at the end of the administration period statistically significantly decreased hemoglobin concentrations were found in the peripheral blood of the high dose animals of either sex. Furthermore, in the high dose males statistically significantly decreased hematocrit values (-5.1%) and increased platelet counts were observed (+20%). In the high dose females mean corpuscular hemoglobin (MCH) was statistically significantly decreased (-5.2%); in the males only a trend towards reduced mean corpuscular hemoglobin was seen.
- 2500 ppm: no statistically or biologically relevant changes
- 500 ppm: no statistically or biologically relevant changes - Clinical biochemistry findings:
- effects observed, treatment-related
- Description (incidence and severity):
- - 1500 ppm: the blood chemistry examinations revealed statistically significantly decreased chloride concentrations (-2.5% and -3%) and increased albumin levels in the high dose males and females, respectively. However, in the females of the highest dose group only a trend towards increased albumin concentrations was seen. Furthermore, a statistically significant decrease in triglycerides was found in the high dose males (-43%); in the sera of the females statistically significantly increased creatinine concentrations (+9%) and decreased glucose levels (-12.5%) were detected. After 3 month, alkaline phosphatase activities were statistically significantly increased in the sera of the high dose males and females. Moreover, a marked increase in cyanide-insensitive palmitoyl-CoA-oxidation was detected in the liver of the high dose animals of either sex (+824% in male, +680% in females). No other statistically or biologically relevant changes were noted.
- 2500 ppm: statistically significant increases in magnesium (9%) and liver cyanide-insensitive palmitoyl-Coenzyme A-oxidation (47%) in females and a statistically significant increase in albumin (6%) in males. No other statistically or biologically relevant changes were noted.

- 2500 ppm: increase in absolute liver weight in females and relative liver weight in males
- 500 ppm: no treatment-related weight changes - Gross pathological findings:
- no effects observed
- Neuropathological findings:
- not examined
- Histopathological findings: non-neoplastic:
- effects observed, treatment-related
- Description (incidence and severity):
- - 15000 ppm: liver cell hypertrophy due to peroxisome proliferation in both sexes, increase of basophilic (thyreotrophic cells in the anterior part of the pituitary gland in male rats (8/10), hypertrophy of the follicular epithelium of the thyroid glands in both sexes
- 2500 ppm: liver cell hypertrophy in one male, increase of basophilic (thyreotrophic cells in the anterior part of the pituitary gland in male rats
(3/10), hypertrophy of the follicular epithelium of the thyroid glands in 8 males and 4 females
- 500 ppm: no treatment-related changes - Histopathological findings: neoplastic:

- Description (incidence and severity):
- There were some additional statistically significant inter-group differences in the results of clinical pathology testing. These deviations are marginal, incidental or inconsistent, when compared with the other sex, or lack dose-response relationship. Accordingly, these findings are considered to be of no toxicological significance.
