A single sample of parotid fluid was collected from 23 healthy young adult males under conditions of no exogenous stimulation. Each subject also provided seven additional samples collected under varying conditions of stimulation. Rates of flow were purposely controlled in an ascending-descending pattern to provide optimal conditions for studying the effect of different rates of gland function. Calcium, magnesium, and total protein were determined. Calcium concentration was positively correlated with rate of flow r .775, P .01 protein level was likewise positively related to flow rate r .558, P .01 magnesium concentration was negatively related to flow r -.666, P .01. The complexing of calcium by protein could feasibly account for the diametrically opposing secretory patterns found for these divalent cations of the alkaline earth group. Author
