Effect of Caerulein with Haloperidol on Monoamine Contents in Rat Brain Regions Treated with Methamphetamine
1986
Abstract To elucidate the mechanism of the antagonistic effect of caerulein on amphetamine-induced hyperactivity, monoamine contents in rat brain regions were measured by HPLC. With a combination of caerulein and haloperidol, dopamine contents in methamphetamine treated-rats were significantly decreased in the striatum, Noradrenaline contents were significantly decreased in the haloperidol-methamphetamine group, but caerulein restored it to the normal levels. Serotonin contents didi not change in any of the groups tested. These results may indicate that caerulein as a neuromodulator in rat brain and causes suppression of hyperactivity induced by metamphetamine.
