[Flow rate-dependent excretion of electrolytes in human parotid and submandibular saliva after stimulation with pilocarpine and lemon juice].

In the present investigation the electrolyte excretion pattern in pilocarpine and citric acid-stimulated human parotid and submandibular saliva was studied dependent upon the flow. In parotid saliva, stimulated by a subcutaneous injection of pilocarpine, significantly higher concentrations of total calcium, ionized calcium, inorganic phosphate and sodium were registered, while the concentration of potassium was significantly lower in comparison to the results obtained after citric acid stimulation. This behaviour was explained as a consequence of a sympathetic-like action of pilocarpine.
