Secretory Cells in the Gills of an Indian Fresh-water Spiny Eel, Mastacembelus armatus (LACÉP.)

抄録

(i) The morphology and histology of the gill filaments of Mastacembelus armatus are described.
(ii) Chloride secreting cells are absent in the branchial epithelium.
(iii) The intra-epithelial branchial glands are the mucous cells.
(iv) COPELAND, KEYS and WILLMER and others have described certain cells in respiratory (branchial) epithelium of fishes which appear in fishes adapted to different osmotic environments.
The fact, however, that BEVELANDER, the author and others, have described only mucous cells in this environment, and the very great possibility that mucus is concerned with ionic transfer suggests that chloride and other ionic transfer effected by the branchial epithelium is mediated by mucous cells.
