Results and discussion
Results of examinations
- Details on results:
- Clinical observations:
At 30 mg/kg/day: salivation and facial staining in both
sexes before dosing and during the Functional Observation
Battery (FOB) clinical assessment.
At 15 mg/kg/day: salivation or stains around the nose
during the latter part of the study were seen, but only in
one of each sex. These findings were also recorded during
the FOB.
Laboratory findings:
At 30 mg/kg/day: lower bodyweight and food consumption in
males. Landing foot splay was smaller than control for
males, however, in the absence of other changes in the FOBs,
this finding is considered not to be adverse.
At 15 mg/kg/day, landing foot splay was smaller than control
in males, however, in the absence of other changes in the
FOBs, this finding is considered not to be adverse.
Effects in organs:
None at any dose level.
