Hyperammonemia was provoked in rats by
urease
injection over three days. Tryptophan transport into the forebrain measured by the bolus injection technique was increased in hyperammonemic rats in comparison with pairfed controls. The concentration of the large neutral aminoacids, of tryptophan and of 5-hydroxyindole acetic acid were increased in the forebrain and brainstem.
Probenecid
administration led to a significantly higher accumulation of 5-hydroxyindole acetic acid in the forebrain of hyperammonemic rats. Since liver function was not impaired the data indicate that hyperammonemia in absence of hepatic insufficiency alters the carrier function for large neutral aminoacids at the blood brain barrier.
