This study was conducted to find out the effects of Woohwangchungsimwon on learning and memory in the NOS inhibitor treated rats. The Morris water maze was used in evaluating them. The result of the study was summarized as follows. 1. In the learning test, three groups have showed a gradual improvement of learning ability by repeating the trials in Morris water maze. WHCS group have showed statistical improvement than control group at 4,5,6 trial(p<0.05, p<0.01, p<0.01). 2. In the memory test, the first latency of WHCH group was statistically shortened than that of control group(p<0.05). 3. In the memory test, there was no statistical difference in the entry number between WHCH group and control. 4. In the memory test, there was no statistical difference in the memory score between WHCH group and control. The result of this experimental study presents that Woohwangchungsimwon has the improving effect on impaired learning and memory in NOS inhibitor treated rats, and implies that Woohwangchungsimwon may be one of the useful prescription for the treatment of vascular dementia after cerebral ischemia.
