摘要
本文报道应用血管铸型扫描电镜观察方法,研究了趾甲床区微循环血管的形态。在甲床近甲根部2/5区,微血管沿趾甲的长轴呈平行排列;在甲床中2/5区,微血管互相交叉,形成多角形网眼;在甲床前1/5区,交叉排列的微血管与趾尖部皮肤乳头层微血管的斜行血管网相移行。
The vascular morphological character of the microcirculation in the nail bed of the toe have been studied with the scanning electron microscope.Three types of vascular network were identified:1)The blood vessels at the proximal two fifth of the nail bed were parallelly arranged.2)At the middle two fifths of the nail bed,the blood vessels interwoved with each other and formed the polygonal vascular networks.3)At the distal one fifth of the nail bed there were only a few vascular loops running in a slanting position.These loops were connected with the vascular network from the papillary layer of the skin of the toe.
