    Blood vessels in the tongue of the kitten: Scanning electron microscopy of microcorrosion casts (1979)

    Notes: Summary The subepithelial blood vessels of the dorsal surface of the tongue in young kittens has been studied by scanning electron microscopy of microcorrosion casts. These vessels entwine the vallate papillae distributed in the pharyngeal part of the tongue, form hairpin loops in association with the small conical papillae along the sides and at the tip of the tongue and establish regularly distributed subpapillary conglomerations over almost its entire oral part. These conglomerations lie directly on veins. Small arterioles reach the vessels surrounding the individual subpapillary conglomerations. By contrast with the arrangement of the superficial vascular bed in the tongue of the dog and some other mammals, no anastomoses between arteries and veins were observed in the kitten between the vessels which supply and drain the subepidermal capillaries.

    On the fine structure of the gas gland in some fishes (1969)
    Springer
    Cell & tissue research 102 (1969), S. 333-356

    Notes: Summary The fine structure of the gas gland cells in Perca and Acerina was studied with the light- and electron microscope. In some of the animals the gas glands were stimulated by the single or repeated removal of the gas from the swimbladder. In this group of fishes the changes in the organization of cytoplasm of the gas gland cells accompanying an intense production of gas have been studied. In the control animals, cells of the gas gland are packed with granules of glycogen except in the perivascular region. A high and protracted activity of the gland results in the disappearance of glycogen, in an increase of the number of cytoplasmic structures, especially the Golgi complex and lysosome-like bodies, and in a very strong proliferation of the external nuclear membrane. The function of the glandular cells and possible causes for the observed alterations in the cytoplasmic organization during an increased gas production are discussed.

    Scanning electron microscopy of microcorrosion casts of the vascular bed in the skin of the spotted salamander, Salamandra salamandra L. (1979)

    Notes: Summary Microcorrosion casts of blood vessels in the skin of the spotted salamander, Salamandra salamandra L., were studied using scanning electron microscopy. The investigated vessels include a subepidermal network of respiratory capillaries and the vessels of poison glands. A hypothesis is proposed, according to which both types of vascular beds possess a common origin. Probable factors involved in the differentiation of the primary netword of the subepidermal vessels in larvae are indicated and speculation concerning the supposed mosaic type of circulation in the capillaries of the subepidermal respiratory bed is presented.

    Model of skin vascularization in Rana esculenta L.: Scanning electron microscopy of microcorrosion casts (1978)
    Springer
    Cell & tissue research 191 (1978), S. 539-548

    ISSN: 1432-0878
    Keywords: Frog skin ; Respiratory capillaries ; Capillary networks ; Microcorrosion casts ; Scanning electron microscopy

    Topics: Biology , Medicine
    Notes: Summary Microcorrosion casts of blood vessels in the skin of Rana esculenta L. were examined by means of scanning electron microscopy with particular reference to the subepidermal network of respiratory capillaries. Due to the fact that arteries and veins lie in the deeper layers of the stratum spongiosum of the corium, the respiratory vessels form a morphologically homogeneous network. Functionally, however, this network is subdivided into small areas with a centripetal direction of blood flow. The deep capillary net, situated at the base of the stratum compactum of the corium, is not so dense as the respiratory network and does not directly communicate with it. Alveolar glands of the skin have no effect on the distribution of capillaries in the two networks.
