title: Determination of N-acetylaspartic acid in human cerebrospinal fluid by gas chromatography-mass spectrometry.
abstract: N-Acetyl-L-aspartic acid was identified and determined in human cerebrospinal fluid. The concentration in lumbar fluid was about 2 nmol/ml and about 20 nmol/ml in ventricular fluid. There was no difference between healthy subjects and schizophrenic patients.
