Summary

The influence of salivation on the location of gustatory alkaline phosphatase has been examined. In untreated rats, taste buds at the ends of fungiform papillae showed almost no activity. However, if salivation was suppressed for 12 hours in fasted animals, alkaline phosphatase activity could be clearly demonstrated in association with these taste buds. The results indicated that alkaline phosphatase may be removed from its site of secretion by saliva and that the enzyme is secreted from fungiform as well as circumvallate and foliate papillae.
