| Abstract | Wistar rats were implanted with a probe for brain microdialysis in the striatum, and measured for two major dopamine metabolites, 3,4-dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA). Intraperitoneal chlorpromazine (5 mg/kg) increased the concentrations of both metabolites in the dialysate when the determinations were carried out before 90 min after the administration. An apparent difference between the declines in concentrations of DOPAC and HVA was observed. Although the concentration of HVA maintained higher levels for over 6 h after the administration, DOPAC underwent a decrease in its concentration after the maximum level, which occurred at 90 min after the administration. These results are discussed in terms of the different distributions of two enzymes related to the metabolism of dopamine, catechol-O-methyltransferase and monoamine oxidase. |
