Any other information on results incl. tables

A dose of 200 mg/kg body weight was tolerated by male rats without mortalities, clinical signs, effects on weight development and gross pathological findings. In females of the 200 mg/kg dose group the motility was decreased, breathing labored, and diarrhea and lateral position were observed. Additionally to the signs described, at 2,000 mg/kg piloerection, decreased reactivity, uncoordinated gait, narrowed palpebral fissures, and abdominal position, and in one female each, temporary tonical cramps and spasmodic state were detected. The signs observed started 2 hours after administration and lasted up to day 3. All females of the 2,000 mg/kg dose group and one female of the 200 mg/kg dose group died.
