Popis:	(1) Simple esterase activity has been demonstrated in the gustatory epithelium of man and dog by the simultaneous coupling azo dye technique using α-naphthol and naphthol As acetate. Unfixed cryostat and fixed paraffin sections were used. (2) A peculiar pattern of simple esterase activity was encountered in which – contrary to what was to be expected – the taste bud-carrying papillae showed a very poor reaction while there was a gradual increase in the enzyme intensity as the epithelium was traced away from these papillae. (3) It seems that among the reported differences between simple esterases and cholinesterases is this differential activity in relation to the gemmal system. (4) A peculiar difference in the enzyme activity was reported between the unfixed cryostat and the fixed paraffin sections in the human material.
