The effects of physostigmine and procyclidine, as a combinational prophylactic regimen for organophosphate poisoning, on learning and memory process were examined in rats administering subcutaneously. Procyclidine at doses of 3 through 10 ㎎/㎏ produced significant impairment of learning and memory process in step-through passive avoidance test. However, this harmful effect of procyclidine (3 and 5 ㎎/㎏) was reversed by simultaneous injection of physostigmine (0.1 ㎎/㎏). Procyclidine at doses of 7 and 10 ㎎/㎏ produced reversible inhibition of learning and memory process in Morris water maze test. Physostigmine (0.1 ㎎/㎏) recovered the memorial impairment induced by procyclidine in this test. In conclusion, procyclidine can affect learning and memory process at the doses not less than 3 ㎎/㎏, and the dose of procyclidine to influence the learning and memory process in rats might be increased to more than 5 ㎎/㎏ by the simultaneous administration of physostigmine (0.1 ㎎/㎏).
