摘要：

An acute intraperitoneal injection of phencyclidine (PCP) caused a tetrodotoxin-reversible increase in extracellular release of 3,4-dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA) in the dialysates from the medial frontal cortex of the rat. Moreover, there was an increase in the tissue content of DOPAC and HVA with acceleration of dopamine (DA), but not noradrenaline, utilization in the cortical area after systemic administration of PCP. These results suggest that PCP facilitates DA metabolism in the medial frontal cortex by increasing impulse flow in the DA neurons projecting to the prefrontal region. © 1990.
