The aim of this preliminary study was to examine the use of sAA measurements as objective indicators of psychological and physiological stress levels by examining sAA changes in volunteers subjected to conditions similar to those suffered by children with severe motor and intellectual disabilities and cerebral paralysis. Twelve healthy volunteers were required to not move or speak, as is found in patients suffering from total paralysis, for 30 min. Saliva samples were taken at three points, and sAA activity was measured using a hand-held monitor before the test, immediately after the test, and 10 min after the test. In the present study, a marked increase in sAA activity due to physiological stress and a rapid return to the baseline level were observed. Many subjects felt bodily pain and psychotic discomfort. This measurement method is useful for evaluating stress in children with severe motor and intellectual disabilities, who can not fully express their emotions or communicate with their caregivers.展开更多

Psychosocial stress increases the release of sAA as a useful marker for autonomic nervous system (ANS). To our knowledge, although some studies have evaluated sAA levels under psychosocial stress, no studies have investigated the changes in sAA activity that occur in junior high school students who are not attending school due to social anxiety disorder (SAD). We aimed to investigate the relationship between the sAA levels and psychiatric states of such patients. Methods: The study subjects consisted of SAD patients (n = 39) and healthy controls (n = 57). We used a portable hand-held monitor to measure the level of sAA and State-Trait Anxiety Index (STAI) to evaluate the psychiatric state. Results: The patients’ sAA activity was significantly higher than that of the controls (n = 57) (p < 0.001). Significant differences in heart rate (HR) (76.10 ± 11.96 vs. 68.69 ± 10.61, respectively, p < 0.01) and STAI scores (both the STAI-State and STAI-Trait scores) (49.35 ± 10.57 vs. 41.24 ± 8.59, respectively, p < 0.01;55.69 ± 10.44 vs. 45.61 ± 9.36, respectively, p < 0.001) were detected between the patients and healthy controls. Conclusions: These results indicated that junior high school students with SAD exhibit a higher state of anxiety and high autonomic activity, probably due to changes in the sympathetic nervous system. As a result, junior high school students with SAD are expected to exhibit high levels of sAA accompanied by anxiety symptoms.展开更多

Any loss of salivary alpha-amylase (sAA) activity in relation to the saliva volume absorbed and harvested by centrifugation was examined. A pooled saliva sample prepared from stimulated whole saliva (collected by drooling) of 30 subjects was used. Three different saliva volumes (2.9 ml, 1.5 ml, and 0.8 ml) were tested on cotton rolls and two (0.03 ml, and 0.015 ml) on cotton pellets. The sample sAA activity was determined from the hydrolysis of 2-chloro-4-nitrophenyl-α-D-maltotrioside. In comparison with the original drooling sample, no sAA loss was observed in 1.5 ml samples tested with Salivette, while a significant decrease of activity was recorded with smaller volumes. VSM collected samples showed a non-volume dependent decrease of sAA activity of about 25%. Salivette requires large saliva volumes to allow an accurate sAA estimation. With cases of limited saliva access, VSM may be a suitable sampling device.展开更多
