Summary

The fluorescence histochemical examination on biogenic amines of the rabbit's foliate papilla revealed that a specific monoamine exhibiting an yellow fluorescence was present in a certain cell type of taste buds. The fluorescence had the emission maximum at 520 mμ and faded rapidly under the influence of the UV-irradiation. The green fluorescence of adrenergic nerve had the emission maximum at 480 mμ and was fairly stable upon the UV-irradiation. The yellow fluorescence disappeared completely following reserpine treatment, while it was markedly enhanced by nialamide treatment. From the observations, it is suggested that certain taste bud cells of the foliate papilla contain a biogenic monoamine, probably 5-hydroxytryptamine (serotonin).
