Rats were treated with physostigamine acutely and subacutely for 7 days. The duration of tremor, striatal acetylcholinesterase(AChE) activity and the occurrences of dopaminal antagonist-induced catalepsy were measured. During the daily treatment with 0.75mg/kg of physostigmine, the durations of tremor were markedly reduced. However, the tremors were ot occurred in the continuous infusion up to 0.20mg/kg/hr. Striatal AChE activities were significantly inhibited(8.25%) early hour, but twenty-four hour after daily administration with physostigmine AChE activities during the continuous infusion with physostigmine were also significantly inhibites (30-60%).
