This study was performed to ascertain the relationships between oral motor functions, such as those of the tongue and lips, and age in the community-dwelling elderly, as well as to investigate the effects of these factors on masticatory performance. The subjects were 268 healthy elderly Japanese living in Kyoto. They were divided into four age groups and(More)
A palatal augmentation prosthesis (PAP) is used in postoperative patients with oral cancer as an intraoral appliance. The purpose of this study was to use ultrasound imaging to evaluate the effects of a PAP on lingual movement dynamics when postoperative patients with oral cancer swallowed food while wearing a PAP and to elucidate the effectiveness of the(More)
We investigated the effect of platelet-derived growth factor B homodimer (PDGF-BB) on inorganic phosphate (Pi) transport activity, which has been reported to be involved in the mechanism of atherosclerosis, in A-10 rat aortic vascular smooth muscle cells (VSMCs). PDGF-BB time- and dose-dependently stimulated Pi transport in A-10 cells. Using northern blot(More)
OBJECTIVES The aim of this study was to examine the relation between the degree of tongue-coating and oral function. BACKGROUND Tongue-coating is a moss-like deposit which forms over the tongue surface, and includes micro-organisms, food residues, and abrasive epithelia. It is considered that motor function of the tongue and lips and saliva secretion(More)
The aim of this study was to evaluate the effect of Palatal Augmentation Prosthesis (PAP) for an Amyotrophic Lateral Sclerosis (ALS) patient. The patient's palatogram was taken during swallowing to assess her lingual function. A PAP was provided to assist her with feeding and swallowing functions. The patient's lingual pressure strength showed increases,(More)
AIM The aim of this study was to develop a simple staging classification to measure leisure activity and social communication among the elderly at geriatric health care facilities. METHODS In order to construct a staging scale for measuring the participation of the elderly subjects, we developed a list of 28 items for three domains: leisure activities,(More)
Disabled children suffer not only from their primary disease, but also from other complications, including food refusal. The purpose of this study was to elucidate the relationship between these conditions and food refusal in disabled children. The effectiveness of feeding therapy in treating food refusal was also examined. The study subjects were 67(More)
AIM The purpose of this study was to examine whether the improvement of oral functions could prevent increase in the level of care needed in the elderly by analyzing the relationship between the level of care needed and labial functions. METHODS The subjects were 114 elderly people who were healthy or needing care (44 men, 70 women; average age 81.3 +/-(More)
The objective of this study is to examine how occlusal status and swallowing function influence the nutritional improvement achieved by appropriate feeding assistance in the institutionalized elderly. We studied 38 residents (mean age 82.04 +/- 7.35 years) in a nursing home. Their nutritional status was evaluated by biochemical analysis, and the following(More)
