过去十年间,由于电子显微镜、细胞化学、免疫细胞学的应用和提高,使内分泌病理学有了很大的进展,为许多正常和异常的内分泌细胞和组织的结构与功能提供了大量资料。近三年提出了一个新的概念:胺原摄取及脱羧(Amine Precursor Uptake and Decarboxyla-tion,缩写为 APUD)细胞系统。本文拟从胚胎学、组织学、细胞化学等方面阐明这一系统的 Over the last decade, great progress has been made in endocrine pathology due to the application and enhancement of electron microscopy, cytochemistry, immunocytology, and extensive information on the structure and function of many normal and abnormal endocrine cells and tissues. In the past three years, a new concept has been proposed: Amine Precursor Uptake and Decarboxylation (APUD) cellular system. This article intends to elucidate this system from aspects of embryology, histology and cytochemistry
