After administration of monoamine precursors, taste buds in the fungiform and foliate papillae of the mouse were observed by means of electron microscopy and fluorescence histochemistry. The taste buds in the fungiform papillae differed in the ultrastructure of their apical regions from those in the foliate papillae, which contained the same taste buds as those described in the circumvallate papillae. The gustatory cells in both the fungiform and foliate papillae were capable of taking up monoamine precursors, although this ability was greater in the latter papillae. The results suggest that, not only in the circumvallate papillae but also in both the foliate and fungiform papillae, monoamines might be involved in neurotransmission from the gustatory cells to the nerves.
给予单胺前体后，通过电子显微镜和荧光组织化学观察小鼠菌状乳头和叶状乳头中的味蕾。菌状乳头中的味蕾其顶端区域的超微结构与叶状乳头中的不同，叶状乳头中的味蕾与轮廓乳头中描述的味蕾相同。菌状乳头和叶状乳头中的味觉细胞都能够摄取单胺前体，尽管后者乳头中的这种能力更强。结果表明，单胺不仅在轮廓乳头中，而且在叶状乳头和菌状乳头中都可能参与从味觉细胞到神经的神经传递。
