Amino acid
neurotransmitters represent a major class of compounds that are involved in
neuronal communication at CNS
synapses, which can provide the basis for a variety of disease diagnosis and
treatments and the study of the mechanism of mental illness. An analytical
method for the determination of several amino acids in saliva was established
with reversed-phase high performance liquid chromatography (RP-HPLC) with UV detector.
About ten kinds of amino acids were detected in saliva. Nine subjects have participated in the
stress experiments which have undergone a 50-min three-dimensional cartoon
watching. The result of the experiment has proved that four kinds of salivary amino
acids respond to the vision stress experiment obviously
