Phencyclidine (PCP) is a dissociative drug and an antagonist of N-methyl-D-aspartate (NMDA) receptor. The effects of PCP treatment on neuropeptide Y (NPY) system in the arcuate nucleus of the rat hypothalamus were examined both by immunocytochemistry and in situ hybridization. In acute PCP-treated rats, the NPY-immunoreactive perikarya appeared in the arcuate nucleus but no perikarya were...
Phencyclidine (PCP) is a dissociative drug and has been known to be an antagonist of N-methyl-D-aspartate (NMDA) receptor. We examined possible effects of acute treatment with PCP on neuropeptide Y (NPY) immunoreactive nerve fibres and cell bodies in rat forebrain by immunocytochemistry combined with morphometric analysis. Following the treatment, significant alterations were observed...
