The amount of medication was kept constant throughout the study. Three of the 7 patients treated with VPA and 1 of the 5 with cyproheptadine showed improvement. HVA levels significantly decreased and cAMP and cGMP levels significantly increased. MHPG levels increased significantly during the treatment with VPA but declined during cyproheptadine treatment. There were no significant correlations between the degree of improvement in TD and the changes of amine metabolites or cyclic nucleotides. None of the pre-treatment values for CSF amine metabolites or cyclic nucleotides were different from those of 15 chronic schizophrenics without TD as controls. Decrease in HVA and increase in cGMP during the treatment might indicate the normalization of dopaminergic-cholinergic imbalance in the brain. Furthermore, amine metabolites and cyclic nucleotides were measured in 5 chronic schizophrenics with parkinsonian tremor. Low HVA and 5HIAA levels and high cAMP levels were observed in tremor group. However, only 5HIAA levels in tremor group were significantly lower than those in age-matched control group. It is suggested that neuroleptic-induced tremor may be attributed to serotonergic dysfunction in the brain. No potential conflict of interest relevant to this article was reported.

岡山医学会 Acta Medica Okayama 0030-1558 92 5-6 1980 遅発性ジスキネジア患者のアミン代謝 ―Oxypertine及びHydroxyzine Pamoateの効果より― 567 573 EN Takuo Nagao Cerebrospinal fluid HVA, MHPG, 5HIAA, cAMP and cGMP were measured in 12 chronic schizophrenic patients with tardive dyskinesia before and after the administration of oxypertine, hydroxyzine pamoate or placebo. Lumbar puncture was performed after probenecid administration. HVA levels significantly decreased and cAMP levels significantly increased after oxypertine treatment. Three of the four patients treated with oxypertine showed improvement in tardive dyskinesia. 5HIAA levels significantly decreased during hydroxyzine administration. Two of the four patients improved in tardive dyskinesia showed decrease of HVA after hydroxyzine treatment. There were no significant alterations of amine metabolites and cyclic nucleotides in the patients with placebo. Decrease of HVA may indicate the normalization of hyperdopaminergic state. It has been recognized that oxypertine is a noradrenaline depleting agent and hydroxyzine has an antiserotonic and antihistaminic properties. Noradrenaline and/or serotonin may have an effect on dopaminergic function in the central nervous system. No potential conflict of interest relevant to this article was reported.
