Outline of Final Research Achievements

Microdamage in load-bearing biological tissues is an important factor related to their homeostatic responses and diseases. However, there have been only a few reports on the microdamages not only in hard tissues such as bones but also in soft tissues such as blood vessels, tendons, and skins. In the present study, changes in the mechanical properties of osteoporotic bones, ultraviolet-irradiated skins, and hypertensive arteries were elucidated by means of compressive, tensile, or internal pressure tests. It was speculated that the decreases in the mechanical strength were linked to the microdamages in the tissues. We have an insight into the mechanisms of homeostatic responses and healing process in biological tissues.
