Examinations
- Observations and examinations performed and frequency:
- CAGE SIDE OBSERVATIONS: Yes
A cageside examination was conducted at least once daily for any signs of morbidity, pertinent behavioral changes and signs of overt toxicity.
The littering and lactation behavior of the dams was generally evaluated in the mornings in combination with the daily clinical inspection of the dams.
On weekdays (except public holidays) the parturition behavior of the dams was inspected in the afternoons in addition to the evaluations in the mornings.
DETAILED CLINICAL OBSERVATIONS: Yes
Detailed clinical observations (DCO) were performed in all animals prior to the administration period and thereafter at weekly intervals. The animals were transferred to a standard arena (50 × 37.5 cm with sides of 25 cm high).
The following parameters were examined: abnormal behavior when handled, fur, skin, posture, salivation, respiration, activity/arousal level, tremors, convulsions, abnormal movements, impairment of gait, lacrimation, palpebral closure, exophthalmus, feces (appearance/consistency), urine, pupil size
BODY WEIGHT: Yes
Body weight was determined before the start of the administration period in order to randomize the animals. During the administration period body weight was determined on study day 0 (start of the administration period) and thereafter once a week at the same time of the day (in the morning).
The body weight change of the animals was calculated from these results.
The following exceptions are notable for the female animals:
- During the mating period the parental females were weighed on the day of positive evidence of sperm (GD 0) and on GD 7, 14 and 20.
- Females with litter were weighed on the day of parturition (PND 0) and on PND 4.
- Females without a litter and without positive evidence of sperm in the vaginal smear were weighed weekly. These body weight data were solely used for the calculations of the dose volume.
FOOD CONSUMPTION:
Generally, food consumption was determined once a week for male and female parental animals, with the following exceptions:
- Food consumption was not determined during the mating period (male and female F0 animals)
- Food consumption of the F0 females with evidence of sperm was determined on GD 0-7, 7-14, 14-20.
- Food consumption of F0 females, which gave birth to a litter, was determined for PND 1-4.
Food consumption was not determined in females without positive evidence of sperm (during the mating period of dams used in parallel) and females without litter (during the lactation period of dams used in parallel).

- Description (incidence and severity):
- On study day 7 (premating) mean body weight of male animals in test group 3 (1000 and 600 mg/kg bw/d) was significantly decreased (-6%). Although not significantly altered, mean body weight loss in female animals was observed after 7 days of treatment.
Mean body weight change values during premating were significantly decreased in male animals of test group (1000 and 600 mg/kg bw/d) between study days 0-7 (-84%) and 0-13 (-48%).

These findings were assessed as being related to treatment with the test substance by irritating the upper digestive tract.
No other findings were observed for male and female animals in test group 1 and 2 (100 and 300 mg/kg bw/d) nor for male and female animals of test group 3 (1000 and 600 mg/kg bw/d) after reducing the dose level. - Water consumption and compound intake (if drinking water study):

- no effects observed
- Description (incidence and severity):
- No test substance-related effects.
- Gross pathological findings:
- effects observed, treatment-related
- Description (incidence and severity):
- Treatment of male and female Wistar rats with up to 1000 and 600 mg/kg bw/d of the test substance led to treatment-related findings in the upper digestive tract (starting at 100 mg/kg bw/d in males and 300 mg/kg bw/d in females). The hyperplasia, hydropic degeneration of squamous cells and inflammatory cell infiltrates, occasionally with multinucleated giant cells in the forestomach as well as the hyperemia, eosinophilic cytoplasmic change, increased mitotic figures, submucosal edema and inflammatory cell infiltrates in the glandular stomach were regarded to be signs of a slight irritating effect of the test substance. These findings were almost exclusively observed around or at the margo plicatus and in the glandular stomach in the fundic area. They were regarded to be adverse. The increase in thickness in the duodenum (only males >= 300 mg/kg bw/d) was also regarded to be treatment-related and as the specific mechanism could not be determined, it was also judged to be adverse in nature. All these adverse findings described above are regarded to be local irritating effects but no systemic toxicity.
- Histopathological findings: non-neoplastic:
- effects observed, treatment-related
- Description (incidence and severity):
- Treatment of male and female Wistar rats with up to 1000 and 600 mg/kg bw/d of the test substance led to treatment-related findings in the upper digestive tract (starting at 100 mg/kg bw/d in males and 300 mg/kg bw/d in females).

The increase in thickness in the duodenum (only males >= 300 mg/kg bw/d) was also regarded to be treatment-related and as the specific mechanism could not be determined, it was also judged to be adverse in nature. All these adverse findings described above are regarded to be local irritating effects but no systemic toxicity.
- Other effects:
- effects observed, non-treatment-related
- Description (incidence and severity):
- Findings which occurred either individually or were biologically equally distributed over control and treatment groups, were considered to be incidental or spontaneous in origin and without any relation to treatment.
