ИЗМЕНЕНИЕ СОДЕРЖАНИЯ НЕКОТОРЫХ НЕЙРОМЕДИАТОРНЫХ АМИНОКИСЛОТ У ПАЦИЕНТОВ С ХРОНИЧЕСКИМИ ГЕПАТОПАТИЯМ

Abstract

Glycine, Gamma-aminobutyric acid (GABA), Glutamate, and Aspartate are neurotransmitter amino acids. It was examined 24 patients with chronic hepatopathy: 12 patients with chronic HBV infection (group I) and 12 patients with hepatic steatosis (group II), the control group (CG) consisted of 12 practically healthy individuals. Quantitative determination of Aspartate, Glutamate, Glycine and GABA in blood serum was carried out using liquid chromatography. In I-st group of patients the level of Glycine was 18.76±1.45, GABA - 0.83±0.06, Aspartate – 5.56±0.97, and Glutamate – 6.34±0.70 mcM/dL. In II-nd group: the level of Glycine was 22.37±0.91, GABA - 0.77±0.03, Aspartate – 5.16±0.74, and Glutamate – 7.87±1.47 mcM/dL. In CG: the level of Glycine y was 22.93±2.21, GABA – 0.55±0.06, Aspartate – 2.69±0.45, and Glutamate – 12.46±1.92 mcM/dL. A violation of neurotransmitter amino acids metabolism is found in chronic hepatopathy. A decrease in glycine and glutamate was observed in patient’s blood serum, with an increase in GABA and aspartate. These disorders are most profound in individuals with chronic viral infection B.
