determination of gamma - aminobutyric acid by high-performance liquid chromatography
gamma-aminobutyric acid is the main inhibitory amino acid neurotransmitter in several areas of the brain. measurement of gamma-aminobutyric acid in the brain will help elucidate its metabolic rote and diagnostic value. the liquid chromatography (lc) system consisted of a delivery pump. male rats (150-250g) were used in this study. the brain was rapidly removed from decapitated animals. trie chr...
متن کاملGamma-Aminobutyric Acid (GABA) Monograpy
Introduction Gamma-aminobutyric acid (GABA) is a major neuro transmitter widely distributed throughout the central nervous system (CNS). Because too much excitation can lead to irritability, restlessness, insomnia, seizures, and movement disorders, it must be balanced with inhibition. GABA – the most important inhibitory neurotransmitter in the brain – provides this inhibition, acting like a “b...
متن کاملNeuroprotection by selective allosteric potentiators of the EP2 prostaglandin receptor.
Activation of the Galphas-coupled EP2 receptor for prostaglandin E2 (PGE(2)) promotes cell survival in several models of tissue damage. To advance understanding of EP2 functions, we designed experiments to develop allosteric potentiators of this key prostaglandin receptor. Screens of 292,000 compounds identified 93 that at 20 microM (i) potentiated the cAMP response to a low concentration of PG...
متن کاملMetabolism and functions of gamma-aminobutyric acid.
Gamma-aminobutyric acid (GABA), a four-carbon non-protein amino acid, is a significant component of the free amino acid pool in most prokaryotic and eukaryotic organisms. In plants, stress initiates a signal-transduction pathway, in which increased cytosolic Ca2+ activates Ca2+/calmodulin-dependent glutamate decarboxylase activity and GABA synthesis. Elevated H+ and substrate levels can also st...
متن کاملEffect of Curcumin on the Hypothalamus Levels of the Potent Inhibitory Neurotransmitter ,Gamma aminobutyric acid
Background: There are some reports in the literature showing that hypothalamus synthesizes and secretes amino acid neurotransmitters. According to several studies, elevated serum levels of gamma-amino butyric acid (GABA), a potent inhibitory neurotransmitter, have recently been implicated in the pathogenesis of neural diseases. The purpose of this research was to estimate the effects of curcumi...
