Objective:To study age-related changes of stimulated whole saliva flow rate and nitric oxide level in healthy adults.Methods:97 healthy adults were divided into four age groups:20-39 years (youth group), 40-59 years (middle-aged group), 60-79 years (elderly group), and 80 years and over (macrobian group).The volunteers were asked to restrain from breakfast in the morning.After mouth rinse with 2.5 ml/L chlorhexidine,20 ml/L citrate was dropped on the anterior third of the tongue dorsum of the subjects for two minutes at the pace of 1 drop every 20 seconds.Then the subjects rinsed their mouth 3 times with double-distilled water within 1 minute,then saliva was collected for 5 minutes. The volume of saliva was documented. Samples were frozen at -70 ℃ until assayed. The rates were calculated. Nitric oxide concentrations were measured with nitrate reductase and the Griess reagent, and then nitric oxide output (mol/min) was calculated.Results:(1) The flow rate of stimulated whole saliva in youth group was significantly higher than that in middle-aged, aged and macrobian groups(P 0.05 ). (2) There were no significant differences in nitric oxide concentrations between any two of the groups. Output of nitric oxide in youth group was significantly higher than that in middle-aged, aged and macrobian groups(P0.05). Conclusion:Nitric oxide exists in saliva of healthy adults. Stimulated whole saliva flow rate and nitric oxide output decreases with aging.
