Abstract
C57BL/6N were orally administered ACE at 20 mg/kg (with reference to LOAEL in general pharmacology test of the central nervous system) and their blood was collected over time. It was analyzed quantitatively using LC-MS/MS. Then, we exposed mice to ACE at 20 mg/kg or 7.1 mg/kg (with reference to NOAEL to rats), and their behavior was observed using openfield (OF) test 1 hour after the administration at the former concentration, and using elevated plus maze (EPM) test 1 hour after the administration at the latter concentration. In addition, C57BL/6J were administered ACE at 30 mg/kg (with reference to NOAEL in the subacute toxicity test) and Nicotine, which is the typical agonist of nAChR, at 1.6 mg/kg (with reference to 1/2 LD50), and the neuronal activity in somatosensory cortex was observed over time by using two-photon microscope.
