title: [Morphohistochemical analysis of secretory elements of the olfactory epithelium of marine fish].
abstract: Morphohistochemical characteristics of various secretory elements of the olfactory lining have been analysed in sea fishes. In the investigation epithelium of Chondrostei and Teleostei has been used. For secrete formation, besides supporting cells, specialized secretory elements take part; among them cells of the I, II and III types can be revealed, as well as tubular and alveolar epithelial glands in some species of fishes. The secretory elements of the olfactory lining of the sea fishes produce substances of various chemical nature specific for the given type of formations and not depending on species-specific and ecological specialization. Essential species-specific differences are revealed in distribution, combinations, size and amount of the secretory elements per one unit of the olfactory lining surface. The analysis of these parameters in macro-, medio- and microsmatics, in fishes of various ecology and different systemic position, also demonstrates their differentiation.
