Abstract

The distribution of amyloid P component in normal human adult skin was studied using fluorescent immunohistochemical techniques on frozen sections. Amyloid P component is associated with elastic fibres of all sizes, and is present in the basement membrane of sweat gland ducts. It is not demonstrable in the basement membrane at the epidermo-dermal junction or in the secretory portion of the sweat glands. In the latter site there is however a spiral, fibrillar, elastic plexus closely related to the basement membrane.

摘要

运用荧光免疫组织化学技术对正常成人皮肤冰冻切片进行研究，以探讨淀粉样P成分的分布情况。淀粉样P成分与各种大小的弹性纤维相关，且存在于汗腺导管的基底膜中。在表皮-真皮交界处的基底膜或汗腺的分泌部则无法检测到该成分。然而，在汗腺分泌部存在一个与基底膜紧密相关的螺旋状、纤维状弹性丛。
