A gas chromatographic--mass spectrometric study of profiles of volatile metabolites in hepatic encephalopathy.
J. Chromatogr. A. 226(2) , 291-9, (1981) Volatile organic substances present in blood plasma and cerebrospinal fluids of certain control groups of human subjects and cirrhotic patients some of whom were suffering from hepatic encephalopathy were quantitatively analysed and identified. A rapid, repro... |

[Association of plasma ammonia and GABA levels and the degree of hepatic encephalopathy].
Rev. Invest. Clin. 44(4) , 483-90, (1992) Several toxic factors have been implicated in the pathogenesis of hepatic encephalopathy (PSE) among which ammonia plays a dominant role. More recently, the gamma-aminobutyric acid (GABA) hypothesis in which an increase in the GABA-ergic tone and the presence... |

Plasma levels of pipecolic acid, both L- and D-enantiomers, in patients with chronic liver diseases, especially hepatic encephalopathy.
Clin. Chim. Acta 287(1-2) , 99-109, (1999) Pipecolic acid is regarded as a gamma-aminobutyric acid receptor agonist. Stereochemical studies of pipecolic acid were performed in patients with chronic liver diseases. Plasma D- and L-pipecolic acid were significantly elevated in 15 liver cirrhotic patient... |

Plasma 3-methylbutanal in man and its relationship to hepatic encephalopathy.
Clin. Physiol. 5(1) , 53-62, (1985) 3-Methylbutanal is a volatile aldehyde which in the rat is derived, at least in part, from colonic bacterial breakdown of leucine. It has been proposed as a toxin of importance in the pathogenesis of hepatic encephalopathy in man. A rapid, reliable and highly... |
