鉴于间歇发作的精神错乱与药物产生的卟啉症(Porphyria)的致幻症状相似,乃研究精神失常患者的丝氨酸与甘氨酸的排泄。发现患者粪便中合成卟啉的前体排泄增加,尿中也有卟啉类物质存在。在精神症状发作时,丝氨酸排泄减少,而甘氨酸排泄增加。 Given that intermittent episodes of delirium are similar to the hallucinogenic symptoms of the drug-producing Porphyria, serotonin and glycine excretion are studied in patients with mental disorders. Found in patients with excretion of porphyrin excretion in the excrement increase, there is also the presence of porphyrins in the urine. In the onset of psychotic symptoms, serine excretion decreased, while glycine excretion increased.
