Materials and methods

Principles of method if other than guideline:
BASF-Test
Several groups of 1 to 3 female rats were treated by gavage with preparations of the test substance in 1, 10 and 20% tragacanth solutions, respectively. Group-wise documentation of clinical signs was performed over the 7-day study period. Body weight was determined before the start of the study only, as it was needed for determination of dose. The clinical signs and findings were reported in summary form.
3 animals of the high dose group were sacrificed 31 days after gavage and subjected to gross pathological examinations.
GLP compliance:
no
Test type:
standard acute method
Limit test:
no
