title: [Ultrastructural and histochemical aspects of the rodlet cells from the bulbus arteriosus of Cyprinus carpio L. (Pisces: Cyprinidae) (author's transl)].
abstract: Morphological details of the "Stäbchendrüsenzellen" (PLEHN), rodlet cells syn. pear-shaped cells of the endothel from the Bulbus arterious of carps were studied in the electron microscope. From morphological characteristics, especially from the development of desmosomes with adjacent endothelial cells, it becomes evident, that the cells in question, which are very common in Teleostei, are not of parasitic nature. Specific protrusions of the apical cell poles towards the arterial lumen are indicative of a holocrine type of secretion.
