We have examined mast cell morphology in human papillary muscles obtained from patients subjected to mitral valve replacement. Elongated, metachromatically staining mast cells were found in the connective tissue close to blood vessels and nerves. Electron microscopic examination showed that the most conspicuous features were cytoplasmic granules which displayed a crystalline internal structure and which were surrounded by perigranular membranes. They were composed of a number of coiled electron-dense layers (3 to 4 predominantly) which formed scrolls and gratings. Apart from the crystalline structure, all granules had a dark, uniform matrix. Measurements of crystalline structure periodicity indicated a unimodal distribution around a mean of 85.6 +/- 1.9 A.
我们已经检查了从接受二尖瓣置换术的患者获取的人乳头肌中的肥大细胞形态。在靠近血管和神经的结缔组织中发现了细长的、异染性染色的肥大细胞。电子显微镜检查显示，最显著的特征是细胞质颗粒，其呈现出晶体内部结构并被颗粒周膜包围。它们由许多盘绕的电子致密层（主要为3至4层）组成，这些层形成了卷轴和光栅。除了晶体结构外，所有颗粒都有一个深色、均匀的基质。晶体结构周期性的测量表明，在平均85.6 +/- 1.9埃周围呈单峰分布。
