    Notes: A total of 132 patch tested patients reacted with petechial reactions to cobalt chloride 1 % in petrolatum; 23 were retested with various concentrations of cobalt. In about 60% of those retested the petechial reaction could be reproduced. Histopathological examination showed slight perivascular tymphocytic infiltration, swollen endothelium and extravasation of erythrocytes but no signs of vasculitis.It is suggested that in predisposed patients the petechial reaction following patch testing could be the result of primary irritation.

    Notes: The integrated reflecting powers of two nuclear and one magnetic reflexions of a DyFeO3 crystal have been measured. The results indicate that dynamical magnetic diffraction occurs. In addition, the integrated reflecting power of the magnetic reflexion was measured as a function of the magnetic field applied to the crystal, The results are discussed.

    Einfluß des natürlichen Isotopengehaltes von Nährstoffen auf den Untergrund bei13C-Atemtests (1983)

    Description / Table of Contents: Summary The long-term variation of the mean δ13C-value of breath-CO2 of Europeans (base value −26‰) was ±1‰ over a period of several months. However, the ingestion of products from corn, a C4-plant, caused remarkably higher shifts. In a fasted state and during rest a stability of the base value of ±0.3‰ could be attained for several hours. Longer fasting periods imply a shift of the CO2-δ-value due to the metabolism of body products. — By a change of the main energy source to corn products the δ13C-base line could be shifted to −18‰ within one day. After this shift even the metabolism of products from C3-plants could be investigated. The degradation curve and the integral degradation of fats were largely dependent on the method of application, and the base value largely interfered with the results. The period of maximum disintegration for a naturally and uniformly labelled fat was different from that of an artificially labelled trilinoleate. The results shall be used for the adjustment and the correction of the base line in13C-breath tests, especially with patients under parenteral nutrition.
    Notes: Zusammenfassung Der mittlere δ13C-Wert im CO2 der Atemluft von Europäern (Basiswert −26‰) zeigt eine Langzeitschwankung über mehrere Monate von ±1,0‰; der Verzehr von Produkten aus C4-Pflanzen (z. B. Mais) hat allerdings erheblich höhere Änderungen zur Folge. Im Nüchternzustand und in Ruhe wird während 6 h eine Stabilität des Basiswertes von ±0,3‰ erreicht; nach längeren Nüchternphasen kann aber der Abbau körpereigener Substanzen zu Verschiebungen führen. Durch Umstellung der Energieversorgung auf Maisprodukte ist es möglich, den Basiswert innerhalb eines Tages auf −18‰ zu heben; dann läßt sich auch der Abbau von Substanzen aus C3-Pflanzen verfolgen. Der Verlauf und die Rate des Abbaues von markierten Fetten sind stark von der Art der Applikation abhängig, und die Messung des Gesamtumsatzes wird durch den Untergrund stark beeinträchtigt. Der Zeitpunkt des maximalen Abbaues von uniform markiertem Fett (Sojaöl) unterschied sich von dem eines in der Carboxylgruppe markierten Trilinoleats. Die Resultate sind Grundlage zur Einstellung bzw. Korrektur von Basiswerten bei13C-Atemtests, besonders bei Patienten mit parenteraler Ernährung.

    Die Cnidogenese der Octocorallia (Anthozoa, Cnidaria): I. Sekretionund Differenzierung von Kapsel und Schlauch (1981)

    Notes: Abstract The ultrastructural differentiation of capsule and its relation to tube development is described in several Octocorallia species(Alcyonaria: Alcyonium digitatum, Parerythropodium coralloides, Cornularia cornucopiae, Paralcyonium elegans; Pennatularia: Pteroeides spinosum, Veretillum cynomorium; Gorgonaria: Pseudopterogorgia aerosa), all of which have only one type nematocyst. In the Octocorallia, capsule and tube are secreted successively by the Golgi apparatus associated with a primary centriolar complex. During the secretion of the external tube, the outer capsular wall (sclera) is structurally differentiated; inside the capsule the material of the inner capsular wall is separated from the later capsular content (matrix). The primary wall differentiation enables the capsules to “grow” after capsular secretion has been completed. Following tube secretion, the external tube is completely transferred into the capsule, without the tube wall being transformed into capsular wall, as previously suggested (Westfall, 1966; Ivester, 1977). During early invagination of the tube wall, the coarse, granulated matrix of the external tube is transferred into the internal tube. From this material the spines are developed, which are observed before the tube is completely transferred into the capsule. By a secondary wall differentiation the previously structureless inner capsular wall changes to a complex structure, extending again the capsule, thus mixing the capsular content and enabling the tube to shift to a position, which corresponds with that of mature capsules. These observations demonstrate for the first time the differentiation of the capsule and its close relationship to the differentiation of the tube in nematocysts of Octocorallia.

    Notes: Abstract Migration of cnidoblasts has never been observed in Anthozoa. In contrast to hydrozoans, anthozoans are repeatedly reported to develop nematocysts locally without migration in the entoderm as well as in the ectoderm. The majority of the nematocysts studied in different Octocorallia species (Alcyonaria:Alcyonarium digitatum, Parerythropodium coralloides; Gorgonaria:Pseudopterogorgia aerosa; Pennatularia:Veretillum cynomorium) originate from the ectoderm of the scapus, where, however, no mature nematocysts occur. Cnidoblasts containing immature nematocysts accumulate in the distal scapus, from where they migrate singly like amoebae into the pinnulae of the tentacles. The nematocysts mature during migration, during which the capsular matrix becomes completely electron-translucent. Only in the oral disc, where few nematocysts occur, do they mature locally without migration. In the Octocorallia, nematocyst development and maturation takes places only in the ectoderm. Development of nematocysts has never been observed in the entoderm, nor in the pharynx; this demonstrates its entodermal origin. The entoderm contains only degenerated or phagocytized nematocysts. Contrary to hydrozoans, the mature anthozoan cnidocyte is rounded and has no processes to the mesogloea. Instead of a cnidocil it has a ciliary cone consisting of a normal flagellum, stereocilia and macrovilli. The cnidocyte is characterised by abundant electron-translucent cytoplasm and nematocyst-anchoring structures made up of cross-striated, collagen-like fibrillae and a fibrous basal ring. The position of the cross-striated fibrillae is distally similar to that of the supportive rods in hydrozoan cnidoblasts. The present study clearly demonstrates that structure and, possibly, function of an octocorallian cnidocyte is much simpler than that of a hydrozoan cnidocyte. On the other hand, cnidoblast migration, occurring in Hydrozoa as well in Octocorallia, turned out to be a much older phylogenetic character than was formerly believed.

    Description / Table of Contents: Abstract Measurements of the equatorial X-ray small-angle scattering are reported for 9 polyacrylnitrile fibers. They are evaluated according to Porod's theory. Data on void fraction and inner surface are obtained. With several samples, a Gumier-evaluation of the inner portion is possible, agreement is satisfactory. An attempt is made to interpret the results obtained with the help of a cyhndric model.
    Notes: Zusammenfassung Von 9 Polyacrylnitril-Fasern wird die diffuse äquatoriale Röntgenkleinwinkelstreuung gemessen und nach der Porod'schen Theorie ausgewertet, wobei Daten über den Hohlraumteil und die innere Oberfläche erhalten werden. Bei einigen Proben ist auch eine Guinier-Auswertung des Innenteils möglich; die Übereinstimmung ist gut. Es wird versucht, die Meßresultate anhand eines Zylindermodells zu interpretieren.
