    Abstract:
    Parotid saliva was collected in 10-minutes-fractions during rest and stimulation from 66 healthy individuals. The time of collection was 80 minutes, in every sample flow-rate, total-protein-concentration, IgA- and Lysozyme-content were determined. According to sex and age of the individuals, the results obtained were classified in four groups. Stimulation produced characteristic changes in the flow-rates, which seemed to be correlated with the age of the persons. The total-protein-concentration of the single samples showed great differences; yet, regarding flow-rate and proteinconcentration together, the so calculated secretion of protein of every gland was almost the same. Secretion of IgA was dependent on age and sex: the secretion-rate was greater in females than in males. Besides, younger people had lower IgA-concentrations than older ones. On the other hand, lysozyme-secretion was reciprocal to IgA-secretion. The concentration of lysozyme was much higher in young persons compared with the older group. The clinical importance of this findings is discussed.
