摘　　要：目的 :探讨脊髓内部血管构筑和分布 ,为脊髓缺血性的有关病变、治疗和预后提供形态学基础。方法 :应用碱性磷酸酶血管染色法 ,对脊髓内部血管 ,用体视学方法作计量和观察。结果 :在脊髓内部灰、白质的毛细血管体密度 ,表面积密度、长度密度存在着差异。结论 :灰质内毛细血管的体密度 ,表面积密度、长度密度均明显高于白质 ,灰质前角的毛细血管量明显多于后角 ,而白质毛细血管的体密度是 :前索 >侧索 >Objective:To explore the angioarchitecture and distriburtion of blood vessels in the spinal cord and to provide anatomic basis for treatment and prognosis of ischemic pathological changes of the spinal cord. Methods: Blood vessels of spinal cord were stained with alkaline phosphatase and then observed with stereology method. Results: There were differences between volume density (Vv), surface density (Sv) and length density (Lv) of blood vessel of grey and white matter inside spinal cord. Conclusion: Volume density (Vv), surface density (Sv) and length density (Lv) of capillary in grey matter are obviously higher than that in white matter; the number of capillary in anterior horn of grey matter are much more than that of posterior horn of grey matter. Moreover, the density of capillary in white matter is: anterior columns>lateral columns>posterior columns.
