骨细胞的功能,可以用骨细胞膜现象来解释。在透射电镜及扫描电镜下初步揭开了它的解剖学奥秘。骨细胞膜受激素的影响而对细胞外液及骨液间的钙浓度起调节作用;它具有电性能,在机械应力下产生压电效应,可刺激骨生长;它有二种电流来源,所产生的电位差可影响钙的渗透性。在它的表面有激素受体,对多种激素如PTH、CT等产生细胞应答。胞体钙浓度及cAMP的改变,很大程度上传递着激素应答和电反应。目前国外对骨细胞膜的研究,尚在萌芽阶段。其重要性表现在,此研究已达骨细胞超微结构的水平,已超越单一器官的范畴。因此,有的国家如西德己将此列为国家科研项目,这是国外医学新的动向之一,值得注意。 The function of bone cells can be explained by the phenomenon of the bone cell membrane. Under the TEM and scanning electron microscopy initially opened its anatomical mystery. Osteocyte membranes are affected by hormones and play a regulatory role in the calcium concentration in extracellular and bony fluids; they have electrical properties that generate piezoelectric effects under mechanical stress that can stimulate bone growth; it has two sources of current produced The potential difference can affect calcium permeability. There are hormone receptors on its surface that produce cellular responses to various hormones such as PTH, CT, and others. Changes in cellular calcium concentration and cAMP, to a large extent, transmit hormone response and electrical response. Currently foreign research on bone membrane, is still in its embryonic stage. Its importance lies in the fact that this study has reached the level of osteoblast ultrastructure beyond the scope of a single organ. Therefore, some countries such as West Germany have listed this as a national scientific research project, which is one of the new trends in foreign medicine and is worth noting.
