| Outline of Final Research Achievements |
In this study, in order to clarify the involvement of estrogen in salivary secretion ability and its molecular mechanism, early menopausal mice by OVX were analyzed as model animals. Salivary secretion decreased with OVX decrease of blood estrogen concentration, and model animal of xerostomia in menopause could be constructed. Furthermore, supplementation of estrogen improved the amount of saliva secretion and acinar shrinkage, and it was shown that estrogen is greatly related to the salivary secretion ability of the salivary glands. As a mechanism of this phenomenon, focusing on the control of mitochondrial function by estrogen, we analyzed mitochondrial function and others. As a result, it was suggested that a qualitative change in mitochondria, probably a change in morphology, accompanying the change in the amount of estrogen occurred.
