Summary A fluorescent histochemical technique has been applied to study human gingival tissue obtained at autopsy. Specific catecholamine fluorescence was demonstrated in the gingival arteries of infants, children and younger adults. A marked diminution in the specific fluorescence in the tissues from the older subjects was noted. Possible reasons for this loss of specific fluorescence are discussed.
