title: [Plasma levels of mediator amino acids in patients with Parkinson disease].
abstract: Content of neurotransmitter amino acids before and after treatment with He-Ne-laser was measured in blood of two groups of the Parkinson's disease patients distinguished by low (first group) and high (second group) activity of monoamine oxidase B and Cu/Zn-superoxide dismutase. An increase in taurine level at the early stage of the disease (first group of patients) suggests that taurine may be a marker of compensatory abilities of the organism. The violation of the glutamate/taurine balance at the later stages of the disease and its normalization following the laserotherapy accompanied improvement of neurological symptoms.
