摘　　要：目的　进一步探讨外丘穴“地”处的血管分布和钙富集情况，为经络穴位提供一些形态学基础资料。方法　下肢标本，用乳胶或墨汁灌注等方法，经巨微解剖、光镜辅以图象分析测量，又以质子激发Ｘ线荧光发射技术（ＰＩＸＥ）测标本钙含量。结果　骨间膜外丘穴位处血管密集，外径为１４～８４ μｍ ，其血管密度（Ａａ％ ）值为非穴位区的３．２７倍（３１．１２／９．５２）。ＰＩＸＥ见外丘穴位区钙含量平均为非穴位区钙的６．８０ 倍，穴位区钙最高点的位置，平均在７寸之上４．７５ ｍ ｍ 处。结论　外丘穴“地”的位置，有特定动脉分支分布，其血管密度高，穴位处骨间膜上钙高，ｘ２ 且集中于７ 寸附近。Objective To further investigate the distribution of blood vessels and the enrichment of calcium at point Waiqiu “earth” and furnish some basic morphological data on meridional points. Methods Lower limb specimens were prepared by perfusion of emulsion or prepared Chinese ink. A measurement was taken by macroscopic and microscopic dissections and image pattern analysis performed under an optical microscope. Calcium content in the specimen was determined by proton induced X ray emission (PIXE). Results Blood vessels were dense in the interosseous membrane at point Waiqiu, which was 14~84 μm in external diameter. The density of the blood vessels (Aa%) was 3.27 times that in non point area (31.12/9.52). PIXE showed that Calcium content in point Waiqiu area was an average of 6.80 times that in non point area, and the position of the maximum calcium content was an average of 4.75 mm in depth 7 cun above lateral malleolus. Conclusion Specific arterial branches are distributed and the density of the blood vessels is high at point Waiqiu “earth”. Calcium in the interosseous membrane at the point is high in content and concentrates near 7 cun above lateral malleolus.
