[Amylase activity, protein concentration and flow rate of unstimulated human parotid saliva (author's transl)].
Unstimulated parotid saliva was collected of 90 persons without diseases of the salivary glands. Amylase activity, flow rate and protein concentration were determined in the 90 saliva samples. Saliva was collected under standardized conditions by means of a catheter introduced into the secretory duct. Amylase activity as well as flow rate and protein concentration are log-normally distributed in both unstimulated and stimulated parotid saliva. The donors' age had an influence on flow rates but not on amylase activity or protein concentration. The values obtained in the described manner of "healthy" persons (with respect to salivary glands) will be used as controls in clinical studies with persons suffering inflammatory and noninflammatory salivary gland diseases.
