Electron microscopy has revealed the presence of a special cytoplasmic body in the centrosomal area of pinealocytes of the golden hamster, Mesocricetus auratus. It consists of branching electron-dense ribbons embedded in a flocculent matrix of moderate electron density, and is tentatively named the 'striped nebulous body' (SNB). The dense ribbon usually appears as a thick band accompanied by a parallel thin one to one side. The SNB is not bounded by a membrane, and is roughly round or kidney-shaped. Closely associated with the SNB are centrioles, microtubular sheaves and striated fibrils, the latter two being centriolar derivatives. The observations suggest that the SNB might be formed by the amalgamation of these microtubular sheaves and striated fibrils. In golden hamsters, pinealocytes often have multiple centrioles and centriolar derivatives. The SNB of adult hamsters is seen in the pinealocytes of both sexes, irrespective of the season of the year and the activity of the pineal gland. The functional significance of this body remains to be studied.
电子显微镜检查显示，在金黄仓鼠（Mesocricetus auratus）松果体细胞的中心体区域存在一种特殊的细胞质体。它由嵌入中等电子密度絮状基质中的分支状电子致密带组成，暂称为“条纹状模糊体”（SNB）。致密带通常表现为一条粗带，一侧伴有一条平行的细带。SNB无膜包被，大致呈圆形或肾形。与SNB紧密相关的是中心粒、微管束和横纹纤维，后两者是中心粒衍生物。这些观察结果表明，SNB可能是由这些微管束和横纹纤维融合形成的。在金黄仓鼠中，松果体细胞通常有多个中心粒和中心粒衍生物。成年仓鼠的SNB在两性的松果体细胞中均可见，与一年中的季节和松果体的活动无关。该细胞质体的功能意义仍有待研究。
