[Change in salivary nitric oxide levels in students in the examinational period].
The influence of examination-induced psychoemotional stress on hemodynamic parameters and salivary nitric oxide (NO) levels was studied in students. Before examinations, the examinees with a sympathotonic response (75.0%) were observed to have diminished salivary NO excretion that was retained within 24-hours after an exam. There was a significant negative correlation between the amount of NO and the values of blood pressure. The examinees with a parasympathetic response (25%) were found to have elevated salivary NO levels with lowered blood pressures in the pre- and postexaminational periods.
