Outline of Final Research Achievements

This study aimed to clarify whether stimulating the pharynx increases secretion of hormones into thyroid venous blood in anesthetized rats. A soft balloon was pushed into the pharynx from the mouth intermittently to stimulate the pharynx. The secretion rate of thyroxine and calcitonin doubled during pharyngeal stimulation. These responses were abolished by cutting the superior laryngeal nerves connecting the pharynx and the thyroid gland to the brain, and the activities of these nerves increased during pharyngeal stimulation. These results suggest that the response is a reflex, in which activation of pharyngeal mechanoreceptors produced an activation of the parasympathetic nerve innervating the thyroid.
From these results, it was concluded that the secretion of thyroxine and calcitonin increases during swallowing due to the neural reflex.

Academic Significance and Societal Importance of the Research Achievements

高齢者のフレイル予防のために「口から食べる」重要性が指摘されている。しかし、その理由はよくわかっていなかった。サイロキシンは、全身の細胞の代謝を高め、精神刺激作用ももつ。カルシトニンには、骨を強くする働きがある。したがって、嚥下に伴い甲状腺からのこれらのホルモン分泌が反射性に促進されるという本研究の成果から、「口から食べること」がこころやからだを活性化し、生きる意欲を高める理由の一つが明らかとなり、嚥下機能の維持がフレイル予防につながる科学的論証を提供した。本研究の成果は、高齢者のフレイルを予防する新しい方法開発への応用につながるだろう。
