 note = {超音波パルス法を用いて，100 月齢のウマの左右第三中足骨皮質骨の MHz 域の超音波縦波の伝搬特性 (減衰と音速) を実験的に検討した．また，同部位におけるハイドロキシアパタイト (HAp) 結晶配向強度を評価し，音速との関連を評価した．その結果，健常な中足骨の骨軸方向の超音波縦波音速分布は炎症骨の音速分布と異なった．また，炎症部で減衰が大きかった．HAp 結晶配向強度の分布は音速分布と類似し，高い相関が確認された．ウマ第三中足骨のこれらの結果はウシ大腿骨と異なった．ウマとウシの走行時の脚部への荷重や衝撃の違いが影響している可能性が示唆された．, Using an ultrasonic pulse method, we evaluated wave propagation characteristics (velocity and attenunation) in the cortical bone of the equine left third metatarsal bone. HAp crystal orientations were evaluated by using the X-ray diffractometer. As a result, the distribution of longitudinal wave velocities in axial direction in the left third metatarsal bone was different from that of inflamed bone. The velocity was very low in the inflamed area. The distribution characteristics of HAp crystallites orientations was similar to that of wave velocities. In addiation, the correlation between wave velocities and integrated intensities of HAp crystal orientations was high. Some behaviors were different from those of bovine femur, which suggested the difference of load effect.},
