Tourmaline纤维的扫描电子显微镜观察及其对高黏血症家兔皮下血流量的影响

目的：研究Tourmaline纤维的形态特征及Tourmaline纤维对高黏血症家兔皮下微循环血液灌注量的改善作用。方法：对Tourmalinee纤维作扫描电镜观察。用高分子右旋糖酐复制家兔高黏血症模型。用含与不含Tourmaline(对照)纤维的棉絮包裹家兔胸腹部后测6、12及24h时剑突区、左上肢、左下肢固定点皮下血液灌注量变化(用激光多普勒血流仪)。测定反复清洗Tourmaline棉絮对改善血液灌注量的影响。结果：Tourmaline纤维有独特的纵形深沟及微细的环形横向浅沟，纤维表面有大量超微颗粒。与对照组比Tourmaline棉絮包裹的高黏血症家兔剑突区血流量明显增加，其它各区变化不显著。清洗对上述作用无显著影响。结论：Tourmaline纤维具有独特的结构特征，它有改善高黏血症家兔皮下微循环血液灌注量的作用。

Scanning Electro-microscopic Observation of Tourmaline Fiber and Effects of Tourmaline Wadding on Dynamic Changes of Cutaneous Microcirculation Perfusion in Hyperviscosity Rabbits

Objective To study the morphological characterization of Tourmaline fiber and the effects of Tourmaline wadding on improving cutaneous microcirculation perfusion in hyperviscosity rabbits. Methods A scanning electron microscopic observation on fibers was performed. A hyperviscosity model was established by venous injection of high molecular weight dextran. The chest and abdomen of hyperviscosity rabbits were packed by a wadding with Tourmaline or without Tourmaline (control) . Then the cutaneous microcirculation perfusion on fixed area of xiphoid, upper extremity and lower extremity was measured using a Laser Doppler Flowmeter. The influence of reaped washing Tourmaline on the cutaneous microcirculation perfusion was also investigated. Results Tourmaline fiber had a specific morphological characterization and on its surface there were a lot of super - microgranules adhesiveness. The cutaneous microcirculation perfusion in xipoid area significantly increased in Tourmaline group compared with that in control group(P <0.05) . There was no significant change in other areas. Washing of Tourmaline wadding could not induce changes of improving microcirculation perfusion. Conclusions Tourmaline has a specific morphological characterization and a beneficial effect on improving cutaneous microcirculation perfusion in hyperviscosity rabbits.
