[Acrylamid- and immunelectrophoretic separations of human parotid secretions from individuals with parotid tumors, chronic parotitis and sialadenosis (author's transl)].

After previous examinations in normal parotid glands in this paper secretion of proteins in parotid glands with pleomorphic adenomas, Whartin tumors, parotid carcinomas, chronic parotitis and sialadenosis should be studied. Different discelectrophoretic and immunelectrophoretic runs were done. Thereby we got the following changes in electrophoreses: Pleomorphic adenomas generally show a more palid pattern in band-structure, caused by the diminished proteinconcentration in the secretions. Most remarkable are thereby the c1 and d1-4-bands. Immunelectrophoretic separations are normal. Whartin tumors show a different bandpattern in the anodal near gel region, which is enpowered by immunelectrophoretic runs. Secretions from parotid carcinomas show a characteristic change in bandstructure. There are found added bands which result from serumproteins as immunelectrophoretic examinations proof. The same is found in glands with parotitis in contrary to glands with sialadenosis.
