Effect level:

> 2 000 mg/kg bw

Mortality:

Male: 2000 mg/kg bw; Number of animals: 5; Number of deaths: 0
Female: 2000 mg/kg bw; Number of animals: 5; Number of deaths: 0

Clinical signs:

Signs of toxicity related to dose levels: Males: The clinical symptoms of intoxication were observed in four animals- from the 4th to the 7th day, in one animal until eighth day after administration. The animals had motional distresses, the distresses in reaction to impulses,the easy effluences from the eyes and nostrils were detected, the intake of food was delimited and the exaggeration was also detected. On the 9th day after application the visible symptoms of health disorder were finished. No animal was died. Female: Negative impact of tested substance was not so strong in the female group. Moderate health disorders were observed in four animals from the 4th to the 6th day and in one animal until 7th day after the application. The animals showed the decreased reactions to the impulses, their breathing was slow and they did not accept the food. No visible clinical symptoms of intoxication were observed on the 8th day after application. No animal died.

Body weight:

Body weight was observed at the begining and at the end of test . Weight increase or decrease was calculated from difference.

Gross pathology:

Effects on organs: During the test no toxic expose was observed. After 14-days of testing period the surviving animals (from the male group) were killed and disemboweled. The morbid- anatomical diagnosis was negative four animals without any change, one animal was partially peaked with liver hyperemis. For the female group the morbid-anatomical diagnosis was negative only for one animal the liver repletion was registered.
