| Outline of Final Research Achievements |
To date, it has been difficult to directly monitor nerve activity in the salivary glands. We applied an in vivo microdialysis method to the salivary gland to monitor multiple neurotransmitters such as acetylcholine, norepinephrine, serotonin, and amino acid simultaneously in the submandibular gland of rats. We applied in vivo microdialysis to salivary glands and simultaneously monitored multiple neurotransmitters such as acetylcholine, norepinephrine, serotonin, and amino acid in the submandibular gland of rats to analyze the effects of the release of various neurotransmitters in the salivary glands on salivary secretion.The results revealed that the amount of neurotransmitter release in the dialysate reflects neural activity within the salivary glands.

| Academic Significance and Societal Importance of the Research Achievements |
唾液腺in vivoマイクロダイアリシス法が唾液腺内の副交感神経活動の変化を検出するための強力なツールになることが明らかとなった。唾液腺in vivoマイクロダイアリシス法を用いることで唾液腺内神経系を介する唾液腺機能調節機構が明らかにされれば、新たな口腔乾燥症治療薬が開発されることが期待される。
