Results and discussion
Results of examinations
- Clinical signs:
- effects observed, treatment-related
- Description (incidence):
- Two male rats in the 1 .O% dietary group developed bronchopneumonia and were killed on Days 23 and 58, respectively. No other deaths occurred in any group during the test period
- Body weight and weight changes:
- effects observed, treatment-related
- Description (incidence and severity):
- Growth was normal in the 0.1% group, slightly reduced in the 0.5% group, and moderately reduced in those animals consuming 1.0 or 2.0% Lauramide DEA.
- Description (incidence and severity):
- Growth retardation was associated with reduced food intake, at and above the 0.5% level
- Haematological findings:
- effects observed, treatment-related
- Description (incidence and severity):
- Hematological values were normal except for lower hemoglobin, hematocrit, and red blood cell count values in the rats fed 1 .O and 2.0% Lauramide DEA. Serum glutamic oxaloacetate transaminase activities were increased in animals fed diets of 0.5, 1 .O, and 2.0% Lauramide DEA
- Details on results:
- no other effects observed
Effect levels
