Mortality:

Male: 2037 mg/kg bw; Number of animals: 5; Number of deaths: 0
Female: 2037 mg/kg bw; Number of animals: 5; Number of deaths: 0

Clinical signs:

Signs of toxicity related to dose levels: During 14 days observantion period the percentage of the mortality was accounted. Futher the body weight was found out at the beginning and at the end of the experiment and from the difference the increase and the loss were calculated. The clinical symptoms of intoxication were observed next the application, in 30 minutes, in 3 hours, next morning and in the afternoon and further days once a day for 14 days. The clinical diagnistic was concentratedon the observation of skin appearance, fell, visible mucouses, nutrition state, mental and motor activity, reaction to the impulses and the examination of the function of aspirative,digestive, urogenital and circulatory apparatus. All the animals survived the testing period without any symptoms of intoxication.

Body weight:

The animals were weighted in 1., 8., and 15. day.
On the base of body weight of rats at the beginning and at the end of test, weight increase or decrease was calculated.

Gross pathology:

Effects on organs:
After 14 days the surviving animals were killed and
disemboweled, their apparatuses and their muscles were
macroscopicly considered. Their size, colour, shape,
structure and consistency were considered.

No toxic effect on the organs were found after sacrifice on
day 15.

Other findings:

Signs of toxicity (local):
The light local effects of the substance were fully lost at

the end of the test.
