We investigated daily individual change of salivary IgA secretion rate of five female volunteers (Age: 27-37 years). Whole unstimulated saliva during 5 minutes were obtained at six collection points in five days:[1]-just after awakening;[2]-at 10: 00 a. m.;[3]-just before lunch;[4]-at 3: 00 p. m.;[5]-just before supper;[6]-just before going to bed We recorded the weight of saliva (g/5min) contained in each sample, and then assayed the salivary IgA (mg/dl).
The results of daily change of the salivary IgA secretion rate were as follows. In all individuals, the salivary IgA secretion rate was highest at awakening, but it decreased quickly and after 10: 00 a. m. it showed a plateau state.
Next, we studied the relationship between salivary IgA and the results of egogram (ECL) in 55 third year dental school students (Male: 40; Female 15). As a result, we found significant negative correlations between salivary weight and egogram's AC points (Adapted Child) in Females (r=-0.52), and between weight and egogram's A points (Adult) in both males and females (r=-0. 29).We also found out a positive correlation between contents of salivary IgA and egogram's CP points (Critical Parent) (r=0.33), and a negative correlation between contents of salivary IgA and egogram's CP points (Nurturing Parent) in males significantly (r= -0.44).
In conclusion, we may suggest that salivary IgA might be affected by the individuals' personalities.
