Abstract

The tendon sheaths (peritenons) of the paravertebral tendons of the tails of Wistar rats were studied using scanning electron microscopy. A phenomenological classification of the osteoid structures of the peritenons is given, with the identification of their persistent and permanent varieties. Sesamoid islets, needle-like and lamellar growths, and rudiments of osteons are classified as persistent. Persistent osteoid structures are well prepared for transformations aimed at strengthening the intracellular matrix under mechanical stress. Permanent osteoid structures are microgranules and faceted deposits of calcium phosphates involved in structural and mechanical processes and hetero- and homogeneous nucleation. Hyaluronate loosens the matrix of sesamoid islets, which increases the mobility of sesamoid globules and creates the prerequisites for their directed migration to areas of increased mechanical stress and foci of possible mineralization of extracellular substance, including fibrillar collagen. Hyaluronate sticks together granules and deposits of structured calcium phosphates and contributes to their growth and fixation in areas of increased risk of mechanical stress. This is a fundamentally important adaptive mechanism for strengthening the tendon tissue, acting in advance.

透明质酸治疗椎旁肌腱腹膜的结构

摘要

使用扫描电子显微镜研究了 Wistar 大鼠尾部椎旁肌腱的腱鞘（腹膜）。给出了腹膜类骨质结构的现象学分类，并识别了它们的持久性和永久性品种。籽粒、针状和层状生长以及骨的雏形被归类为持久性。持久的类骨质结构为旨在强化机械应力下细胞内基质的转化做好了充分准备。永久类骨结构是参与结构和机械过程以及异质和同质成核的磷酸钙的微粒和多面沉积物。透明质酸盐使籽粒胰岛基质松弛，从而增加了籽粒球的流动性，并为它们定向迁移到机械应力增加的区域和细胞外物质（包括纤维状胶原）可能矿化的区域创造了先决条件。透明质酸盐将结构化磷酸钙的颗粒和沉积物粘在一起，并有助于它们在机械应力风险增加的区域生长和固定。这是一种提前发挥作用的增强肌腱组织的根本性重要适应性机制。
