[Sialochemical studies of isolated secretions of the major salivary glands of the head].

The sialochemical parameters total protein, immunoglobulin A, lysozyme, amylase, sodium, potassium, calcium as well as flow rate were estimated in parotid saliva (PS) and submandibular saliva (SMS) in the course of differential diagnostics of salivary gland diseases. In addition to this the quantitative polyacrylamide gel electrophoresis based on 80 PS and 80 SMS normal secretions was performed. Sialochemistry was performed on parotid adenomas (29), carcinomas (9); sialadenosis (8); acute (8) and chronic (13) sialadenitis; dental caries (12 PS and 12 SMS); cystic fibrosis (21 PS and 12 SMS); diabetes mellitus (13 PS and 13 SMS); and hyperthyroilism (9 PS and 9 SMS). Our sialochemical analysis does not allow to distinguish between benign and malignant parotid neoplasms. The significant decrease of sodium in sialadenosis and increase of sodium and total protein in sialadenitis as well as interesting results in cystic fibrosis, diabetes mellitus and dental caries, are emphasised.
