Abstract
|
|
|
In currently, stress diseases are increased that present several sign and symptoms.
Under stress condition, there are dry mouth, burning mouth syndrome, oral mucosa diseases and halitosis more frequently.
Changing of salivary proportion is checked in almost patients with changing of function and structure in salivary gland.
This study purpose are what effect stress does on salivary gland, and a-amylase on salivary gland.
This study was resulted that
1. Under restraint stress, acinar cells are vacuolization and changing of intercellular spaces are separated, and peripheral tissues of duct are changed
2. Acinar cells were shrunk after 3 hours under restraint stress, intercellular space was separated after 6hours, peripheral tissues of duct started to change after 72 hours, and acinar cells and peripheral tissues of duct were all severely changed after 168hours.
3. In immunohistochemical study, amylase reaction was showed partially and irregularly after 3 hours, was getting little milder after 6 hours. And amylase reaction was gradually increased from the time of 12 hours after experiment up to the time of 48 hours after experiment.
But after 168 hours, amylase appearance was diminished.
According this result, emotional stress can change of salivary gland structure, and amylase secretion, the important digestive enzyme from salivary gland is changed and it is supposed to make digestive disorder and to make halitosis efficiency.
So, we need to study about secretion of amylase.
