Mortality: 13/40 mice
Clinical signs:
The treated mice showed compound-related symtoms up to 72 hours including apathy, roughened fur, pallor, prone position, spasm, twitching, shivering, difficulty in breathing, breathing sounds.
Micrroscopic evaluation:
The ratio between normochromatic and polychromatic cells vary in comparison to the negative control,
The positive control, cyclophosphamide, was functional.
