Distinctive globular bodies, ranging in diameter from 0.2mu to 1.5mu, were encountered in the cytoplasm of epithelial cells of human rectal mucosa. These profiles, surrounded by a unit membrane, contained a uniform population of electron-dense rods 50 nm wide and 100 to 250 nm long. Although neither the origin nor the relationships of these rod-containing bodies (R-bodies) to other cytoplasmic organelles could be established, morphologic and cytochemical studies demonstrated clear differences from multivesicular bodies.
在人直肠黏膜上皮细胞的细胞质中发现了直径从0.2微米到1.5微米不等的独特球状小体。这些结构被单位膜所包围，包含一群均匀的电子致密棒状物，宽50纳米，长100至250纳米。尽管这些含棒状体（R小体）的起源及其与其他细胞质细胞器的关系均无法确定，但形态学和细胞化学研究表明它们与多囊泡体有明显差异。
