Outline of Final Research Achievements

We tried to develop the quantitative biomarkers reflecting cerebral environment using MRS and MEGA - PRESS method. The metabolites as the targeted substances are glutathione (GSH) which is an antioxidant stress substance, γ-aminobutyric acid (GABA) which is an inhibitory neurotransmitter, glutamate (Glu) which is an excitatory neurotransmitter and its metabolites Glutamine (Gln) etc. GSH in the brain of smokers was significantly lower than non-smokers, suggesting an increase in oxidative stress with smoking. In patients with chronic pain, Glu and Gln were significantly lower than those of healthy subjects, and GABA tended to be higher, and it was considered that there was excessive reaction of the inhibitory nervous system in patients with chronic pain.
