紫暗舌与舌血流关系的研究

A study on relationship of purple tongue and its regional blood flow

目的 :探索紫暗舌与舌血流的关系。方法 :运用激光多普勒血流仪分别对 5 6例紫暗舌及 5 4例正常舌从舌面多部位测试舌血流灌注量及流速 ,同时进行对照分析。结果 :紫暗舌组患者的舌血流灌注量明显低于正常舌组 (P <0 .0 1) ,而流速明显增快 (P <0 .0 1)。舌体各部位 (舌尖、舌中、舌边 )之间的舌血流灌注量及流速参数接近 ,无统计学差异。结论 :紫暗舌患者舌血流灌注量降低、流速增快。

Objective:To study the relationship of purple tongue and its regional blood flow. Methods:Laser-Doppler flow meter was employed to test the volume and velocity of blood flow at different sites of purple tongue (56 cases) and normal tongue (54 cases), and the test results were analyzed. Results:The volume of blood flow of purple tongue was significantly lower than that of the normal tongue (P<0.01), while the velocity was significantly higher (P<0.01). The volume and velocity of blood flow at different sites of the tongue were similar without significant difference. Conclusion:The volume of blood flow of purple tongue is decreased and the velocity increased. Purple tongue may be caused by dysfunction of the microcirculation of the tongue.
