We confirmed the existence of electric potential differences between saline and collected saliva. The potential difference between saline and resting saliva was about 6mV, and that between saline and stimulated saliva was about 2mV. The former always higher than the latter. Comparing the electric potential changes on the papilla parotidea with other potential changes, the maximum potential difference obtained between the pailla parotidea and lobulus auriculae was about 11mV, the potential between resting saliva and stimulated saliva was about 8mV, and that between saline and stimulated saliva was about 4.5mV. The pattern of electrical changes between resting saliva and stimulated saliva or saline and stimulated saliva were similar to that of electrical changes between tha papilla parotidea and lobulus auriculae.}, pages = {193--199}, title = {Relation between the secretory potential of parotid glands and the generated potential of collected salivas.}, volume = {14}, year = {1995} }
