国人皮肤微血管的三维构筑及其规律性

应用墨汁灌注、光镜观察和ＡＢＳ血管铸型、扫描电镜观察方法，研究成人、儿童和６个月人胚胎皮肤微血管三维构筑的形态学特点，阐释了国人皮肤微血管构筑的普遍性与特殊性规律。结果发现，无论是直接皮肤动脉还是间接皮肤动脉在从深筋膜层进入皮肤各层组织的整个过程中，一边逐渐上升，一边在深、浅筋膜层，真皮网状层，乳头下层及乳头层内形成具有鉴别性特征的五级血管网，为皮肤微循环血管树的五级血管分支。而在指纹、趾纹、鱼际、甲床、包皮、阴囊及龟头等一些特殊皮肤区，微血管构筑则具有其各自特殊的规律性。这种特殊规律性主要表现在皮肤血管树的各级分支的配布特点上。

Three Dimentional Architectural Regularity of Cutaneous Microvessels in Chinese

The morphological characteristics of three dimentional architecture of microvessels in adult,infant and fetus(6 month) and the universal and special regularity of microvascular architecture of Chinese human skin were studied by way of ink injection with LM observation and ABS vascular casting with observation under scanning electron microscope(SEM).Results showed that the cutaneous arteries,either from the direct or indirect cutaneous arteries in the course of entering the skin from deep fascia to the papillary layer,are forming the cutaneous microcirculatory vascular tree and distributing to each skin layer and making the 5 grades of vascular networks which have distinctive features in deep fascia,subcutaneous tissue,network layer of the derma, subpapillary layer and papillary layer.The special microvascular architecture in the special skin areas such as the finger print,the toe print,the thenar,the nail bed,the prepuce,the scrotum,the glans of penis were also oberved.The special regularity mainly showed in each grade of arborescent branches of the cutaneous microcirculatory vascular tree.
