It is important to obtain information about the collagen fiber orientation in biological fibrous tissues such as human and animal skins because the collagen fiber orientation in the skins may closely relate to the motional functions of the body. However, no reports are yet available on the distribution of collagen fiber orientation in a whole skin. The microwave method recently developed by the author was applied for giving the distribution of collagen fiber orientation. A map representing the distribution of collagen fiber orientation was obtained for a leather sheet prepared from the entire skin of a calf. It was found that the direction of collagen fiber orientation was, on an average, parallel to the calf's spinal column and limbs, corresponding to the direction perpendicular to that of skin motions due to eating and walking, and that the degree of orientation was large in the parts where the skin motions were marked. These findings suggest that the distribution map of fiber orientation in calf leather significantly affects the motional functions of its different parts and also hopefully gives useful information for performing an appropriate transplant of skins.
获取有关人体和动物皮肤等生物纤维组织中胶原纤维取向的信息非常重要，因为皮肤中的胶原纤维取向可能与身体的运动功能密切相关。然而，目前尚无关于整个皮肤中胶原纤维取向分布的报道。作者最近开发的微波方法被用于给出胶原纤维取向的分布情况。从小牛整张皮肤制备的皮革片上获得了一张表示胶原纤维取向分布的图谱。结果发现，胶原纤维取向的方向平均与小牛的脊柱和四肢平行，这与进食和行走引起的皮肤运动方向垂直，并且在皮肤运动明显的部位取向程度较大。这些发现表明，小牛皮革中纤维取向的分布图显著影响其不同部位的运动功能，也有望为进行适当的皮肤移植提供有用信息。
