摘要目的 初步探讨血清犬尿喹啉酸(KYNA)含量及犬尿喹啉酸/色氨酸(TRP) 比值(KA/T)在精神分裂症患者抗精神药物治疗中的意义.方法 测定并比较了健康对照组、初始发病未用药SCH患者(SCH I组)、坚持用药SCH患者(SCH II组)血清KYNA、TRP含量及KA/T值.结果 与健康对照组血清KYNA (23.30±8.31)μmol/L、TRP(47.59±10.43)μmol/L比较,SCH I组患者血清KYNA(29.47±12.01)μmol/L和TRP(54.50±9.56)μmol/L含量均升高; SCH II组血清KYNA含量及KA/T比值下降.结论 抗精神药物治疗可能使血清KYNA含量和KA/T比值降低.

abstractsObjective To explore the clinical significance of serum value of kynurenic acid(KYNA) and KYNA/tryptophan (TRP) ratio (KA/T) in patients with schizophrenia(SCH). Methods The SCH patients (n=73) were divided into two groups (drug-naive, first episode patients, patients undergoing antipsychotic treatment) and the concentrations of serum KYNA, TRP in the Sch and health control(n=108) were measured. Results Compared with healthy control, there were significantly increased concentrations of serum KYNA and TRP in the drug-naive, first episode patients, and the serum KYNA and KA/T ratio were significantly decreased in patients undergoing antipsychotic treatment. Conclusion It showed that antipsychotic treatment may decrease the concentration of KYNA and value of KA/T.
