Free amino acids in the tissue of the palatine tonsil and the adenoid were analyzed using a JEOL 6-AS Type Auto-Analyzer, and comparative examination was made on 26 kinds of amino acids discovered. Of these, 23 amino acids showed significantly high values in the palatine tonsil, but hydroxyproline and tryptophan showed somewhat higher values in the adenoid. These results suggest that the metabo...

AIM To investigate the ability of natural chymase inhibitors to modulate histamine release from human mast cells. METHODS Enzymatically dispersed cells from human lung, tonsil, and skin were challenged with anti-IgE or calcium ionophore A23187 in the absence or presence of the natural chymase inhibitors secretory leukocyte protease inhibitor (SLPI) and alpha(1)-antitrypsin, then histamine rel...
