【摘要】 采用双重免疫组织化学染色方法研究了成人胰岛内分泌细胞的分布特点及其与微血管的相互关系。结果发现；①成人胰岛为鞘型胰岛，B细胞位于胰岛中央，A、D细胞位于B细胞周围，形成鞘；②A、D细胞存在位置分布上的一致性；③即使由于有结缔组织隔将胰岛分隔成不同的“亚单位”，其每一“亚单位”的周围部仍为A、D细胞，中央部仍为B细胞；④胰岛A、D细胞距微血管较近。这些研究结果将为进一步研究胰岛内分泌细胞间的功能联系提供形态学基础。更多还原

【Abstract】 Double immunohistochemical stain was used for the study of distribution feature of the endocrine cells of human islets and its relation to the microvasculature. The results were as follows (1)Sheath islet was found in human adult islets and the B cells situated the central part of the islets and arounding it were the A and D cells which formed the sheath of the islts. (2)The identical distribution of the A and D cells was found. (3)Some islets were divided into several "subunite" by connective tissue in which the B cells and A(or D) cells situated the central and peripheral part respectively. (4)The A and D cells were near the microvasculature. These results will provide morphologic basis for the research of the functional relation among the endocrine cells.更多还原
