1H and 31P magnetic resonance spectroscopy in a rat model of chronic hepatic encephalopathy: in vivo longitudinal measurements of brain energy metabolism.

abstract：:The present work was carried out to study the influence of ammonia and factors from sera and cerebrospinal fluid (CSF) from patients with different degrees of chronic liver diseases on [3H]D-aspartate (Asp) and [3H]L-glutamate (Glu) high-affinity uptake into the rat hippocampal formation. For comparison, high-affinity...
