Clinical symptoms:

400 - 500 mg/kg: within 5 min staggering gait, within 13 min paraparesis, within 20 min tetraparesis

700 mg/kg: maximum tolerable dose

> 700 mg/kg: death occurring more or less rapid by respiratory depression

Applicant's summary and conclusion

Conclusions:
For intraperitoneal application the maximal tolerable dose was found to be 700 mg/kg bw in mice. At higher concentrations death occured by respiratory depression with a LD50 of 1,070 mg/kg and a LD100 of 1,600 mg/kg. The target of the acute toxic action of acetophenone was the nervous system.
Executive summary:

Acetophenone was applied by intraperitoneal injection (vehicle olive oil) to mice and clinical symptoms and mortality was investigated. In the dose range of 400-500 mg/kg depression of the nervous system occurred within 5 min indicated by symptoms as staggering gait followed by paraparesis and tetraparesis. The maximal tolerable dose was found to be 700 mg/kg bw. At higher concentrations death occured by respiratory depression with a LD50 of 1,070 mg/kg and a LD100 of 1,600 mg/kg.
