胃经沿线小腿骨间膜的血管及钙的分布

目的：探讨穴位的物质基础及穴位血管与钙的分布。方法：（１）在成人小腿骨间膜的墨汁灌注标本上，观测其胃经（胫侧缘）沿线的３，４，５及７寸（中医使用的同身寸，以下全同）处血管的分布特点；（２）用质子激发Ｘ线发射（ＰＩＸＥ）技术，对胃经沿线的小腿骨间膜组织进行扫描，测得钙的相对含量。结果：（１）胃经沿线３，４，５，７寸处的血管密度（Ａａ％）显著高于各寸之间的血管密度（Ｐ〈０．０１）；（２）各定标点的钙峰

Distribution of vessel and calcium on tibial margin of leg interosseous membrane

Objective: To provide data for exploring the material basis of Acupoints and the relation of accumulation of calcium and vessels at Acupoints .Methods: (1) The distribution characteristics of vessels on tibial side of the interosseous membrane (ST channel 3rd, 4th, 5th, 7th cun ) were observed on Chinese ink vascular perfusion adults legs. (2) The content of calcium on ST channel were determined by proton induced X ray emission analysis. Results: (1) The average density (Aa%) of vessels at the 3rd, 4th, 5th, 7th cun areas of ST channel was significantly higher than that between them ( P < 0.01). (2) The relative content of calcium at the 4 areas was 6.73 times higher on average than that between them. Conclusion: (1) Vessels on interosseous membrane get segmentally distributed, and the density of vessels on Acupoint areas is very high. (2) There are abundent calcium at Acupoints , its accumulation also appears segmentally. [
