| Research Abstract |
In the brain tissue (nucleus accumbens and hippocampus) of phencyclidine-treated mice which is an animal model of schizophrenia, the L-tryptophan (L-Trp)concentration was significantly decreased. This result suggested that dysregulation of L-Trp metabolism occurred in these brain regions.
In the present study, a significant gender difference was observed, namely, L-Trp concentration in the sera of male healthy subjects was higher than that of female healthy subjects. A significant correlation was observed between L-Trp and L-KYN concentrations in male, but not in female subjects. The serum levels of L-Trp, KYN, and serotonin were significantly different between controls and schizophrenia patients, suggesting that determinations of L-Trp, KYN, and 5-HT in serum might be crucial for clinical diagnosis.
