Abstract：
BACKGROUND: Quantitative changes of salivary proteins due to acute stress were detected.
OBJECTIVE: To explore protein markers of stress in saliva of eight medical residents who performed emergency medicine simulations.
METHODS: Saliva was collected before the simulations, after the simulations, and following morning upon waking. Proteins were separated by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE), identified by mass spectrometry (MS), and relatively quantified by densitometry.
RESULTS: Salivary alpha-amylase and S-type cystatins significantly increased, while the ∼26 kDa and low-molecular weight (MW) (<10 kDa) SDS-PAGE bands exhibited changes after stress.
CONCLUSIONS: Alpha-amylase and cystatins are potential salivary markers of acute stress, but further validation should be performed using larger sample populations.
