[The immunglobulin-content of human parotid saliva (author's transl)].

By means of radial immundiffusion, the content of IgA, IgG, IgM and IgE in 22 healthy persons was measured. The parotid saliva has been collected under standardized stimulation-conditions in 10 minutes-fractions during a time of 30 minutes. While IgM and IgE could not be found with this method, IgA and IgG were present in a concentration easy to be measured. For the two immunglobulins, a different and characteristical change in their concentration was found during stimulation. This difference can be explained by the different origin of the substances.
