Materials and methods

Principles of method if other than guideline:
Four groups of 3 male rabbits were exposed to the test substance under occlusive conditions at dose rates of 730, 1450, 2900 and 5800 mg/kg bw. The volume of administration as well as the area covered was not mentioned. Clinial signs and mortalities were observed for 10 days. At the end of observation period, all animals were sacrificed and necropsy was performed.

Results and discussion

Effect levels
Sex:
male
Dose descriptor:
LD50
Effect level:
2 550 mg/kg bw
Mortality:
0/3, 0/3, 2/3 and 3/3 animals died at doses of 730, 1450, 2900 and 5800 mg/kg bw, respectively. The death occured at 7, 5.5-7 hours at the dose levels of 2900 and 5800 mg/kg bw, respectively.
Clinical signs:
Reactions to percutaneous treatment were minimal, with varying degrees of skin irritation. Depression increased during the 7 hours of immobilization. 
Body weight:
Not indicated
Gross pathology:
Necropsy showed constricted kidneys and spleens.
Other findings:
- Histopathology: microscopic examination of tissues of 2 rabbits was normal.
