本文对鲤斯坦尼氏小体进行了显微及超微结构的观察，斯氏小体由许多腺泡组成．根据其组织学变化，可分为发育期、生长期、分泌期及萎缩期．发育期细胞位于腺泡壁或腔中，界线不清，胞核平均直径５．６μｍ，常见有丝分裂现象．生长期细胞位于腺泡周缘，胞质内出现电子密度高的分泌颗粒，细胞器发达，有排列成行的粗面内质网，众多的线粒体以及高尔基氏体．分泌期细胞器缺乏．萎缩期只有细胞核和少量残留细胞质．
In this paper, microscopic and ultrastructural observation of the carp Stein nyud body was carried out. Steinosomes consisted of many acinar bodies. According to its histological changes, can be divided into developmental stage, growth stage, secretory stage and atrophy. Developmental cells located in the acinar wall or cavity, the boundary is unclear, the average diameter of 5.6μm nuclear, common mitosis. Growing cells are located in the periphery of the acinar, the cytoplasm of high electron density of secreted particles appear, organelles developed, arranged in rows of rough endoplasmic reticulum, a large number of mitochondria and Golgi apparatus. Secretion of organelles lacking. Only a small amount of nucleus and residual cytoplasm of atrophy.
