title: Perturbation of secretory Ig A in saliva and its daily variation by academic stress.
abstract: OBJECTIVE
  Several studies have reported that the secretory immunoglobulin A (S-IgA) concentration in saliva is an indicator of psychological stress. The aim of this study was to clarify the relationship between S-IgA and the stress from academic examinations.
  
  
  METHODS
  S-IgA levels in 10 medical student volunteers from the second year course between May 4 and July 13, 2000 were examined using the ELISA method.
  
  
  RESULTS
  There was a tendency for S-IgA in saliva to be higher on the day before academic examinations and during them, and lower on the days between these examinations.
  
  
  CONCLUSIONS
  It may be possible to use this measurement to monitor psychological stress in students and workers.
