[Flow rate, amylase and protein content of parotid saliva in sialadenosis (author's transl)].

Flow rate, protein concentration and amylase activity of parotid saliva were investigated in 17 patients with sialadenosis. The results were compared with the data obtained from 90 healthy controls. Total protein and amylase concentrations of saliva did not change although, under the influence of sialadenosis, the parotid gland clearly shows ultrastructural signs of disturbed protein secretion. Also the flow rates of parotid saliva were the same in sialadenosis patients and the control group. This can be explained by the patho-physiology of parotid secretion from the sialadenotic gland.
