通过电子显微镜检查淡水鲶鱼（Parasilurus asotus）的肾脏。在肾脏中发现了一种特殊类型的细胞，其外观与硬骨鱼鳃丝的氯细胞非常相似，被称为肾氯细胞。该电池的特点是具有广泛的管状膜系统，其直径相当恒定，约为 600 Å。许多线粒体与该系统密切相关。应用钌红作为细胞外空间标记表明管状系统是细胞膜的高度组织化衍生物，从细胞的基底和侧面折叠。与已知具有主动电解质转运的其他类型细胞的精细结构相似性表明这些细胞参与肾内渗透压调节。
The kidney of the fresh-water catfish,Parasilurus asotus, was examined by electron microscopy. A special type of cell, very similar in appearance to the chloride cell of the teleostean gill filaments, is found in the kidney and is referred to as a renal chloride cell. This cell is characterized by an extensive tubular membrane system with a rather constant diameter of approximately 600 Å. A number of mitochondria are closely associated with this system. Application of ruthenium red as an extra-cellular space marker revealed that the tubular system is a highly organized derivative of the cell membrane, infolded from the basal and lateral surfaces of the cell. The fine structural resemblance to other types of cells known to possess active transport of electrolytes suggests that these cells are involved in intrarenal osmoregulation.
