Results and discussion
Results of examinations
- Details on results:
- Clinical observations:
At a dose level of 1000mg Lactam 204,636/kg/day there were
no compound-related clinical changes and no effects on
bodyweight or food consumption.
Laboratory findings:
At a dose level of 1000mg Lactam 204,636/kg/day there were
minimal changes in some clinical chemistry parameters,
namely an increase in creatinine and plasma glucose.
At a dose level of 250mg Lactam 204,636/kg/day there was a
minimal reduction in plasma cholesterol.
Effects in organs:
At a dose level of 1000mg Lactam 204,636/kg/day there was a
slight reduction in brain and spleen weights (of
approximately 15 and 5% respectively). There were no
compound-related changes in macroscopic or microscopic
histopathology.
