SALIVARY MONOAMINE OXIDASE A AND B INHIBITORY ACTIVITIES CORRELATE WITH STRESS

摘要

MAO A and B inhibitory activities were determined, for the first time, in saliva samples. Saliva was collected on 4 occasions from 11 normal subjects (students) before and after delivering an important assessed oral presentation, a naturalistic stress inducing procedure. The first sample was collected 30 minutes before the presentation and 3 more within 40 minutes of finishing the presentation. At each collection a mood adjective checklist was completed. Mean MAO A inhibitory activity correlated with mean MAO B inhibitory activity (r=0.872, p<0.001, n=11). Within subject analysis revealed a positive correlation between MAO A and B inhibitory activity and stress (r=0.400, p<0.01; n=44 and r=0.255, NS, n=38 respectively). Mean MAO A and B inhibitory activity correlated with mean stress (r=0.535, NS, n=11 and r=0.673, p
