Abstract
Both unstimulated and sour lemon-drop-stimulated secretions from the lip mucous glands (LMG) of young adults were collected into micropipettes, by a suction technique, for analysis for total protein, urea and the common electrolytes. The protein, sodium, potassium, calcium, magnesium, chloride and urea concentrations were not very dissimilar from those reported for the major salivary gland secretions. Sodium and chloride concentrations increased markedly on stimulation of flow rate. The inorganic phosphate content of the LMG secretions was only about one-tenth of that in the major salivary gland secretions and bicarbonate was virtually absent, chloride being the predominant anion. Because of the low bicarbonate and phosphate concentrations, the LMG secretions are poorly buffered and the degree of saturation with respect to hydroxyapatite is uncertain. Amylase did not appear to be present in the LMG secretions, but blood-group substances were secreted in much higher concentrations than those present in submandibular saliva.
