PAROTID SECRETION FLOW RATE UNDER DIFFERENT STIMULI
Abstract
Different means for evoking parotid secretion were studied. The greatest unilateral flow was elicited when both gustatory and masticatory stimuli such as sweetened chicle with essential oils were used. A maximum flow rate was established with six grams of gum and the optimum flow of 4.2 ml/5 min with 3.00 grams of material. Frequent renewal of the bolus caused a slight increase in secretory rate, but could not maintain a maximal minute by minute volume. A pronounced masticatory response is evident when values of 3.00 gm and over are used and it appears that this mechanism is the principle one for the elaboration of paratid secretion. Gustatory response by both sweet and acid stimulants produced about 1 ml of secretion for each 5 minute interval regardless of the concentration or the times that the solution was renewed. A separate masticatory action and a separate gustatory action roughly approximate the combined masticatory - gustatory response. (Author)
