title: Concentrations of neopterin and biopterin in the cerebrospinal fluid of patients with Parkinson's disease.
abstract: The concentrations of neopterin and biopterin in CSF of 18 younger and 10 older, control patients and of 18 patients with Parkinson's disease were measured by high-performance liquid chromatography with fluorescence detection. Both neopterin concentrations and the neopterin to biopterin ratios in CSF were lower in 50-year or younger group than in 51-year or older group. Biopterin concentrations were also decreased but not significantly in the older group. The concentrations of neopterin and biopterin in CSF of patients with Parkinson's disease were lower than those of the age-matched older control group. However, the neopterin/biopterin ratios tended to be lower but not change significantly as compared to the age-matched older control group.
