    Notes: Summary Histochemical investigations on enzyme activities in the transitional epithelium showed positive reactions with succinic dehydrogenase, esterase, alkaline phosphatase, acid phosphatase and amylophosphorylase (incl. branching factor). Negative results were drawn from cholinesterase, 5′-nucleotidase, glucose-6-phosphatase, and carbonic anhydrase.

    Notes: Summary Electron microscopic studies on the oesophageal epithelium of the rat revealed for the first time intranuclear granules of keratohyalin. The results strongly suggest that these granules were extruded from the nucleus and were enlarged in the cytoplasm by ribonucleoprotein (RNP) particles aggregating to the keratohyalin.

    Notes: Summary The tension development of the smooth feather muscles of the pigeon was measured (a) on the wing in situ (b) on an isolated innervated skin preparation and (c) on an isolated muscle preparation. The contraction produced by nerve stimulation is biphasic. The second phase can be blocked by α-receptor blocking agents. The mechanism of the first phase is unknown. The preparation seems very suitable for the investigation of neuromuscular transmission in smooth muscle.

    Description / Table of Contents: Zusammenfassung In der II. Mitteilung über die Feinstruktur der Epidermis bei chronischem nummulärem Ekzem wird über die Veränderungen im Str. spinosum berichtet. Folgende Befunde wurden erhoben: 1. Die Veränderungen, vor allem im unteren Str. spinosum, sind durchweg stärker als im Str. basale. Im oberen Str. spinosum sind sie meist geringer als in den unteren Lagen. 2. Charakteristisch ist das gleichzeitige Auftreten von inter- und intracellulären Ödemen. Hieraus ergibt sich das vielfältige morphologische Bild der peripheren Cytoplasmapartien, des Intercellularraumes sowie der intercellulären Verbindungen. 3. Das Auftreten stärkerer intracellulärer Ödeme führt zu einer teilweise extremen Streckung der Intercellularbrücken. Trennungen dieser erfolgen meist durch Abriß außerhalb der Desmosomen, meist in der Nähe der Zellgrenzen. 4. Die zahlreichen, in die Intercellularräume ragenden Mikrovilli und ödemreichen Zellfortsätze werden als morphologischer Ausdruck eines intensiven, aber gestörten Flüssigkeitsaustausches zwischen epidermalen Zellen und Intercellularraum interpretiert. 5. Das Verhalten der Tonofilamente wird im Zusammenhang mit den sich durch das Ödem ändernden intracytoplasmatischen Spannungsverhältnissen diskutiert. 6. Viele intracytoplasmatische Körperchen werden auch in den tieferen Schichten des Str. spinosum gefunden. 7. Die morphologischen Veränderungen an den übrigen cytoplasmatischen Strukturen (endoplasmatisches Reticulum, Golgi-Apparat, Mitochondrien, glykogen, usw.) sowie an den Zellkernen werden beschrieben. Sie sind nicht spezifisch für chronisches nummuläres Ekzem, sondern reflektieren teils „fokale cytoplasmatische Degeneration”, teils erhöhte Epidermopoese.
    Notes: Summary In the II. communication on the ultrastructure of the epidermis in chronic nummular eczema changes on cells of the stratum spinosum are described. The following observations could be made: 1. The alterations, especially in the lower layers of the stratum spinosum, are more pronounced than in the stratum basale (cf. I. communication). In the upper lavers they are less intensive than in the lower layers of the stratum spinosum. 2. Simultaneous appearance of intercellular and intracellular oedema is a characteristic phenomenon. The polymorphic aspect of the peripheric parts of cytoplasma, of the intercellular spaces and of the intercellular connections result from this. 3. The formation of more pronounced intercellular oedemas gives rise to sometimes extreme stretching of the intercellular bridges. They always tear off outside the desmosomes, mostly near the cell border. 4. Numerous microvilli and cell protrusions—rich in oedema—within the intercellular spaces are interpreted as a morphologic sign of an intensive but disturbed exchange of fluids between epidermal cells and the intercellular space. 5. The behaviour of tonofilaments is discussed in relation to the changes of intracytoplasmic tensions due to intra- and intercellular oedema. 6. Many intracytoplasmic bodies are also found in the lower layers of the stratum spinosum. 7. The morphologic changes in other cytoplasmic structures (endoplasmic reticulum, Golgi-complex, mitochondria, glycogen etc.) as well as on the nuclei are described. These are not specific for chronic nummular eczema but reflect focal cytoplasmic degradation or increased epidermopoesis.

    Notes: Summary The avascular chorion adjacent to the placenta of the rabbit has been suggested as a site of transport or resorption of protein and antibodies. In this chorion giant cells are found. These cells are about 60μ in diameter and contain between 5 and 150 nuclei, sometimes even more.

    Notes: Summary Histochemical investigations were carried out in the endometrium of guinea-pigs after administration of ‘Anovlar’ (4 mg ethinylnortestosterone-acetate and 0.05 mg ethynylestradiol). Histochemically a decrease of non-specific esterase activity was found in the endometrial as well as in the glandular epithelium after ‘Anovlar’ treatment. The relationship of this enzyme to synthetic steroid hormones is briefly discussed.
