animals were necropsied and assessed by gross pathology.
ORGAN WEIGHTS
The following weights were determined in all animals sacrificed on schedule: Anesthetized animals, Adrenal glands, Brain, Heart, Kidneys, Liver, Spleen, Testes, Thymus

Fixation was followed by histotechnical processing, examination by light microscopy and assessment of findings on following organs: Adrenal glands, Aorta, Skeletal muscle, Brain, Cecum, Uterus, Coagulating glands, Colon, Duodenum, Epididymis (left), Esophagus, Heart, Ileum, Jejunum, Kidneys, Liver, Lung, Lymph nodes (mesenteric and axillary lymph nodes), Pancreas, Tounge, Pituitary gland, Prostate, Salivary gland, Seminal vesicles, Skin, Semen vesicles, Spleen, Forestomach, Testis, Thymus, Thyroid glands, Trachea, Uterus - Statistics:
- - A comparison of inter-group differences (clinical chemistry, hematology and body weight) was performed using the t-test.
- DUNNETT's test was used to test the hypothesis of equal means.
- Steel-test was used to evaluate the inter-group differences relating to organ weights of each dose group. - Clinical signs:
- no effects observed
- Description (incidence and severity):

- Mortality:
- no mortality observed
- Description (incidence):
- In the present study no animal died ahead of schedule.
- Body weight and weight changes:
- no effects observed
- Description (incidence and severity):
- No test substance-related findings were observed in all parameters under investigation.
- Food consumption and compound intake (if feeding study):
- no effects observed

- Ophthalmological findings:
- no effects observed
- Description (incidence and severity):
- No test substance-related findings were observed in all parameters under investigation.
- Haematological findings:
- effects observed, non-treatment-related
- Description (incidence and severity):
- A decrease of the haematocrit (HCT) value in the male groups 2 - 4 was observed. The decrease of the HCT seems to be compound-and partially dose-related. Additionally the intermediate analysis showed slightly reduced Red Blood Cell (RBC)-value for the male group 4. The observed deviation of the HCT is considered to be incidental/ because the diagnosed values are within the ranges of the historical control. In addition to this, there are no corresponding deviations of the RBC- or MCV-values to prove the biological relevance of this findings.
- Clinical biochemistry findings:
- no effects observed
- Description (incidence and severity):
- No test substance-related findings were observed in all parameters under investigation.
- Urinalysis findings:
- not examined
- Behaviour (functional findings):
- no effects observed
- Immunological findings:
- not examined
- Organ weight findings including organ / body weight ratios:
- no effects observed
- Description (incidence and severity):
- - Absolute organ weights: No test substance-related findings were observed in all parameters under investigation.
- Relative organ weights: No test substance-related findings were observed in all parameters under investigation. - Gross pathological findings:
- no effects observed
- Description (incidence and severity):
- The macroscopical examination of the organs displayed some observations like discolouration of the thymus deformation of the spleen, cyst of the kidney, hydronephrosis, atrophy of the testes, hydrometra and necrosis of the fatty tissue which were considered to be spontaneous. Compound-related macroscopical effects were not observed. The male and female animals of the recovery group 4 (recovery period 33 days) showed no macroscopical compound-related alterations.
- Neuropathological findings:
- not examined
- Histopathological findings: non-neoplastic:
- effects observed, non-treatment-related
- Description (incidence and severity):
- No test substance-related findings were observed in all parameters under investigation. However, in the male and female animals of all groups (including the recovery group 1 and 4) the livers, the heart and the mandibulary lymph node showed effects which were due to a bacteriosis of unknown etiology. The observed germinal hyperplasia of the mandibulary lymph node can be interpreted as a consequence of this bacteriosis.

It is argueable whether the effects observed in the study are sufficient to conclude on a NOAEL of 100 mg/kg bw/d. According to a recent publication by Hall et al., the variation of liver weights without histological evidence or distinct alterations in clinical chemistry is not considered to be an adverse effect. Hall et al. reach the conclusion that only a 2-3-fold increase in ALT (GPT) or a biologically significant change in other biomarkers is considered to be an adverse effect. In the study at hand, the only remarkable alteration in liver parameters was an ALT increase in the highest dose group of males and females, but it was less than 2-fold. Regarding the observed degradations in the kidney, they were not accompanied with relevant biochemical changes (urea, creatinie, sodium, potassium) and were reversible in the recovery group. The absence of adverse effects in the 90-day study further supports the argumentation that the alterations found in the 28-day study were temporary and rather a non-adverse adaptation than an evidence for a toxicological action.
