The catalytic activity of alpha-amylase is significantly elevated in salivary pool from 146 diabetics (2176 +/- 149.3 mu catal.l-1) vs. the salivary pool from 78 nondiabetics (1159 +/- 97.3 mu catal X l-1), the difference in the concentrations of the saliva condensation index (the chloride concentration) in the diabetics and nondiabetics being negligible. Glucose tolerance test has been carried out in 54 subjects. Glucose intake has increased the alpha-amylase catalytic activity and augmented glycosialia in 14 diabetics, in 13 subjects with abnormal glucose tolerance, and in 16 nondiabetics; a negligible rise of glycosialia and a reduction of alpha-amylase catalytic activity have been observed in 11 subjects with a flat glycemia curve. Basing on these data, the authors claim that oral glucose activates amylase and glucose secretion by the salivary glands.
