Behavioral, electroencephalographic, and biochemical changes in porta-cava shunted rats.
1980
Behavioral, electroencephalographic, and biochemical alterations have been studied in rats with porta-caval shunt, up to 45-50 days after the operation. No behavioral or electroencephalographic changes have been observed, while modifications of various amino acids both in plasma and brain have been found. Among all the amino acids considered of particular significance are the plasma and brain increases of tyrosine, phenylalanine, and tryptophan, since they are the precursors of biogenic amines.In fact, the increase of 5-HIAA found in regions of CNS which are richest in serotoninergic synapsis could indicate an increased turnover of 5-HT. On the other hand no significant alterations of turnover of catecholamines have been found.
