Results and discussion

Effect levels
Sex:
female
Dose descriptor:
LD50
Effect level:
> 300 - < 2 000 mg/kg bw
Based on:
test mat.
Mortality:
All animals of the 2000 mg/kg bw test group died at hour 5 or on study day 1 or 2.
No mortality occurred in both 300 mg/kg bw test groups.
Clinical signs:
other: 2000 mg/kg (first test group): Impaired general state, poor general state in one animal, dyspnoea, piloerection, abdominal position in one animal, cowering position, stagger in two animals, exsiccosis in one animal, lack of defecation in one animal, saliv
Gross pathology:
There were no macroscopic pathological findings in the surviving animals of both 300 mg/kg test groups sacrificed at the end of the observation period.
2000 mg/kg bw: Macroscopic pathological findings in all animals that died: Ascites: reddish clear or cloudy liquid; Stomach: gasified; red discolored; black discolored liquid contents; Glandular stomach: dark red discolored (no structure visible) or plane hemorrhage; Small intestine: red discolored; red or black-red discolored contents; Congestion of the kidneys; Dark or light spotted liver; Spleen: black or black-spotted discolored.
