Assessments of the Neurotransmitter Disturbances
The neurotransmitter disturbances, including the alterations of acetylcholine (ACh), gamma aminobutyric acid (GABA), and monoamine oxidase (MAO; total MAO, MAO-A, MAO-B)), were indirectly performed by measuring the suppression activities of acetylcholinesterase (AChE), GABA-transaminase (GABA-T), and all forms of monoamine oxidase (MAO) by using the modified method of Srichomphu and colleagues, as previously mentioned [
