Results and discussion

Preliminary study:
One female rat was dosed with 10 ml/kg oral gavage with the 200mg/ml of the test material in arachis oil giving a total initial dose of 2000mg/kg body weight. No mortality was observed so a further 4 female rats were treated to the same dose.

Mortality:
None
Clinical signs:
other: Hunched posture on day of dosing in three rats. Nothing after that.
Gross pathology:
No abnormalities were noted at necropsy
