    Notes: Summary To prevent the perilymph (guinea pig) from contamination with CSF during the sampling the aqueductus cochleae (AC) was blocked by injection of tissue adhesive into the meningeal aperture. The control of an exact blockage of AC was carried out by examination of perilymph-outflow after opening the cochlea (injection of fluorescein-Na into the CSF-space), analysis of perilymphprotein-concentration, macroscopic and microscopic examination of the temporal bones. In all cochleae we have found the same morphological structures, notwith-standing whether the AC was blocked (for a time from 30 min to 7 weeks) or not: The cochlear aqueduct is filled with a mesh of mesenchymal tissue, which grows more dense towards the cochlear aperture and continues into the round window membrane. From scala tympani the AC is always limited by one layer of cells forming a sort of membrane (under light microscope). It seems possible that CSF moves in the inner of the round window membrane between AC and subepithelian space of middle ear mucosa, whereas perilymph of scala tympani is not in direct contact with the flow of CSF. The scala tympanic side of the round window membrane may be a big area for diffusion and there also may be an exchange between CSF and perilymph. The outflow of CSF into the cochlea after experimental opening of the cochlea is an artifact, caused by damage of pressure equilibration between CSF-space and cochlea. 30 min and 5–7 weeks after blockage no morphological and electrophysiological alterations from those of the control ears were to be seen. The protein concentration, however, increased significantly 5–7 weeks after blockage from normally about 200 mg/100 ml to almost the double especially in the scala tympani (see Table 1).

    Notes: Summary Studies to detect disorders of pulmonary function were performed on 42 workers at a poultry farm. All the subjects were exposed to organic dusts and sensitised to poultry antigens. Typical signs of bird fancier's lung were recorded in two of them. Included in all examinations were immunological diagnosis by means of counter-immunoelectrophoresis, systematic interviewing for case histories, and registration of respiratory symptoms. Pulmonary function was recorded by means of the following techniques: analysis of ventilation (flow-volume indices), respiratory mechanics of the larger airways and lung (body box plethysmography, oesophago-balloon technique), respiratory mechanics of the small airways (closing volume), distributional analysis, diffusion analysis, and blood gas analysis. A disorder of pulmonary function was recordable in 40 sensitised individuals. Such disorder being characterised by obstruction of the larger airways and slight inhomogeneity. The small airways were not narrowed. No restriction nor disturbed diffusion were established. The severity of obstruction was found to be related to the degree of sensitisation. The following more clearly pronounced changes in terms of functional diagnosis were recordable from two poultry workers with allergic alveolitis: obstruction of larger airways with concomitant restriction, marked inhomogeneity, and disorder of diffusion. The disorders, relatively discrete, led to mild PO2-reduction in sensitised individuals, whereas mild hypoxaemia was recorded from subjects with allergic alveolitis.

    Description / Table of Contents: Zusammenfassung Als Ursache der klinischen Erscheinungen bei der Akrodermatitis enteropathica (A.E.) muß ein Zinkmangel als Folge einer Zinkmalabsorption angesehen werden. Durch orale Substitution mit Zink lassen sich die Krankheitserscheinungen beseitigen. Es wird über 2 Geschwister mit A.E. berichtet, die lange Zeit mit Oxychinolinpräparaten mit wechselndem Erfolg vorbehandelt waren. Durch orale Substitution mit Zinksulfat in der Dosis von 110–220 mg täglich wurde eine vollständige und anhaltende Remission erzielt. Gleichzeitig normalisierten sich die vorher stark erniedrigten Serumzinkspiegel. Keine so strenge Korrelation bestand zwischen dem Zinkgehalt der Haare und der Art Der Zinksubstitution. — Wie wir in unserer 1. Mitteilung zeigten, lassen die Paneth-Zellen der Dünndarmmukosa bei A.E. ultrastrukturelle Veränderungen in Form von inhomogenen Strukturen des Zytoplasmas, der Bildung von Riesengranula und Einschlüssen erkennen. Unter der Zinksubstitution kommt es zu einer vollkommenen Normalisierung des ultrastrukturellen Bildes der Paneth-Zellen. Die Veränderungen an den Paneth-Zellen können daher nur die Folge, jedoch nicht die Ursache des Zinkmangels bzw. der Zinkmalabsorption sein.
    Notes: Abstract The basic defect in acrodermatitis enteropathica (A.E.) is zinc deficiency caused by zinc malabsorption. The clinical symptoms disappear and serum zinc levels normalize after oral treatment with zinc. A report is given on two siblings suffering from A.E., both treated with oxyquinolines for a long period with changing clinical success. A permanent clinical remission could be achieved by treatment with zinc-sulphate at doses of 110–220 mg daily. The serum zinc levels normalized. The correlation between the zinc concentration of the hair and the kind of therapy was not very close. As we have shown in our first communication, the Paneth cells of the intestinal mucosa display ultrastructural changes in form of an unhomogeneous structure of the cytoplasm, formation of giant granules, and inclusion bodies. The zinc-therapy led to a complete normalization of the pathological changes in the Paneth cells. Thus, the changes in the Paneth cells in A.E. are the result and not the cause of zinc deficiency.
