The brain histidine level in mice dose-dependently increased 1 and 2 hr after an i.p. injection of 0.5-1.5 g/kg of L-histidine. The treatment with 1.0 and 1.5 g/kg but not 0.5 g/kg of L-histidine significantly decreased the brain levels of tyrosine, phenylalanine and some other amino acids 1 hr later. A complete recovery or a rebound rise of amino acid levels was observed 2 hr after treatment. These results indicate that there is a change in the transport of amino acids into the brain after treatment with large doses of L-histidine.
