Abstract (in Japanese) (See Japanese page) 
(in English) Recently, there are some cases of bone fracture, where the mineral amounts stay normal. One possible reason for this phenomenon is the formation of abnormal collagen cross-links by glycation or aging. In this study, we investigated the effects of glycation on the velocity changes in swine and bovine cortical bones using ultrasound in the MHz range. The velocities in some glycated samples showed initial increases and then decreased. Other showed monotonous decreases of velocity. By the three point bending test, we found that the bone strength was deteriorated by the glycation.
