[Receptor antagonist of NMDA and animal models of schizophrenia].

Schizophrenia is one of the common mental diseases. Because the mechanism of the schizophrenia is significantly complicated, the cause is still unknown. N-methyl-D-aspartate receptor antagonist can simulate the positive and negative symptoms, as well as the cognitive disorder of schizophrenia. Thus it has been widely used to establish the animal models of schizophrenia. The relationship of the three blocking agents of ion channels (phencyclidine, MK-801, ketamine) and the establishment of schizophrenia animal models is reviewed in this article.
