Results and discussion
Results of examinations
- Details on results:
- Clinical observations:
No systemic toxicity was observed in body weights or food
consumption.
Laboratory findings:
No real treatment-related trends occurred.
Effects in organs:
Statistically significant increases in relative liver
weights in the males were observed in the 500 and 1000 mg/kg
groups but no increases were seen in the absolute weights
and were thus considered to be biologically significant.
No histopathology occurred which was compound-related.
