手鱼际、小鱼际皮肤及浅、深筋膜微血管铸型的扫描电镜观察

SCANNING ELECTRON MICROSCOPIC OBSERVATION ON ABS CASTS OF THE FINE VASCULATURE ABOUT THE SKIN,SUPERFICIAL AND DEEP FASCIA OF THENAR AND HYPOTHENAR

本文用2侧成人新鲜尸体上肢,经肱动脉灌注ABS丁酮溶液,制成铸型样品,喷镀金膜。在扫描电镜下,观察了手鱼际和小鱼际皮肤及浅、深筋膜微细血管的立体构筑。微血管网可分为5层:(1)乳头层网:可见排列整齐的皮纹血管及乳头毛细血管;(2)乳头下层网:血管网眼大、小不均,呈多角形;(3)真皮深层血管网:在纵横交错的微血管网中,有散在或聚集成团的毛细血管球;(4)浅筋膜层网:在粗大的血管干周围,形成小叶状血管网;(5)深筋膜层网;可见并行排列的干线血管。左右侧之间、鱼际和小鱼际之间,微血管网的形态无明显差民。

Using two fresh upper limbs of adult,the ABS casts of the fine vasculature about the skin,superficial and deep fascia of thenar and hypothenar were studied by scanning electron microscopy.The microvessel networks contained five layers,that is,(1)the papillary:the capillary loops aligned with the skin-print;(2)the subpapillary;(3)the profund corium:capillaries of the glomus bodies were visible;(4)the superficial fascia:the meshwork being leaf-like;(5)the profund fascia:mainly the line vessels.There is no difference about the morphologic construction of the microvessel networks between the left and the right hand,and between thenar and hypothenar.
