Livers of normal and cirrhotic rats were perfused in vitro with and without amino acid substrates (2.3 mM ornithine, 10 mM glutamine or 20 mM alanine) in order to assess urea formation and amino acid release. The rates of urea production were lower in the livers of cirrhotic rats when compared to those of controls only in perfusions with added substrates. The release of several amino acids by livers of cirrhotic rats was higher than that of controls although the pattern of amino acids in the perfusate was different from that reported in plasma during hepatic insufficiency.
