Levels of secretory immunoglobulin A, lysozyme (muramidase) and albumin in healthy adults of different ages.
The content of secretory IgA (sIgA,) lysozyme and albumin was studied in the saliva of 40 health-service employees of different ages without evident signs of disease. The levels of lysozyme decrease significantly with the advancing age whereas those of sIgA and albumin do not decrease up to the age of 55. The levels of lysozyme and sIgA show a significant mutual correlation.
