[Plasma levels of mediator amino acids in patients with Parkinson disease].

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.

[Biochemical and immunological induces of the blood in Parkinson's disease and their correction with the help of laser therapy].

The influence of laser therapy on the course of Parkinson's disease (PD) was studied in 70 patients. This influence appeared adaptogenic both in the group with elevated and low MAO B and Cu/Zn SOD activity. Laser therapy resulted in reduction of neurological deficit, normalization of the activity of MAO B, Cu/Zn-SOD and immune indices.

Laser modification of the blood in vitro and in vivo in patients with Parkinson's disease.

The effect of He-Ne laser radiation on activity of MAO B, Cu/Zn-SOD, Mn-SOD, and catalase in blood cells from patients with Parkinson's disease was studied in vivo and in vitro. The effects of intravenous in vivo irradiation (intravenous laser therapy) were more pronounced than those observed in similar in vitro experiments. It is concluded that generalized effect of laser therapy involves interaction between blood cells.
