摘　　要：目的:为中医甲诊提供血管形态学依据。方法:用血管铸型标本、手术显微镜及扫描电镜观测等方法研究了甲床的血供。结果:甲床的血供主要来自指掌侧固有动脉的尺侧支和桡侧支共同发出的指背动脉弓分支、指腹动脉弓分支及甲皱支。甲床内纵行小动脉在甲床的上中1/3及中下1/3交界处相互吻合,分别形成甲床第二、三级动脉弓。结论:甲床的血供丰富,由于血流变化而引起的甲床色泽的改变,是中医判断疾病病情的依据。Objective:To supply the vessel morphologic basis for the nail diagnoses of the Traditional Chinese Medicine. Methods:The angioarchitecture of the matrix unguis was studied by corrosion - cast,scan electromicroscopy and surgical microscopy. Results: The blood of unguis was supplied by the subbranches of the bilateral branches of the proper palmar digital artery, which included the dorsal artery arch and its rami,the ventral artery arch and its rami,and the subbranches to the margo unguis. The main arteriole in the matrix unguis were longitudinal. They anastomosed mutually to form the second and third artery arches in the super - median 1/3 and low - median 1/3 of the matrix unguis. Conclusion: The blood supply to the matrix unguis was abundant. The change of the colour of the matrix unguis resuleting from the changes of the blood could be utilized by Traditional Chinese Medicine to diagnose some diseases.
