Outline of Final Research Achievements

In this study, we have shown the followings: (1) the amount of Substance P (SP) in saliva shows a negative correlation with age, (2) it is increased by taking ginger-containing oral disintegration (OD) tablets, (3) there is a negative correlation between functional evaluation score of swallowing by endoscopic examination and age, and (4) the swallowing score improves by taking ginger-containing OD tablets.
These results were suggested that SP in saliva may work as a clinical marker for swallowing function and ginger-containing OD tablets may improve swallowing function.
