    Description / Table of Contents: Zusammenfassung In unserer Versuchsanordnung haben wir ein Modell einer in traabdominellen heterotopen Pankreas-Duodenum-Autotransplantation geschaffen. Zwei Hunde überlebten für lange Zeit in befriedigendem Zustand. Zu Anfang, unmit telbar nach Pankreas-Autotransplantation, konnte ein Gewichtsverlust infolge exokriner Pankreasunterfunktion beobachtet werden. 3 Monate später hatten die Tiere wieder ihr Ausgangsgewicht. Im Gegensatz zur exokrinen Funktion konnte die endokrine über den gesamten Beobachtungszeitraum, mit Ausnahme weniger Tage unmittelbar nach der Transplantation, erhalten werden. Im Gegensatz zu Kontrolltieren zeigte sich beim Tolbutamid-Test eine signifikante Verlängerung der Hypoglykämie. Der Glucosetoleranz Test verlief normal. Eine Fibrosierung nach Pankreas-Autotransplantation konnte nicht beobachtet werden. Dieses experimentelle Modell ist sehr hilfreich für die Langzeit Beobachtung einer heterotopen Pankreas-Autotransplantation. Denervierung und Unterbrechung der lymphatischen Bahnen scheinen zwar einen vorübergehenden, jedoch keinen dauerhaften Einfluß auf die endokrine oder exokrine Pankreasfunktion zu haben.
    Notes: Summary We have described a technique of one stage intraabdominal heterotopic pancreaticduodenal autotransplantation which has resulted in long term survival of dogs in good health. Malnutrition related to pancreatic exocrine hypofunction occurs initially but gradual recovery by 3 months nutrition is normal. In contrast, endocrine function is well preserved throughout the postoperative period except for a few days immediately after transplantation. Tolbutamide testing showed a significant prolongation of hypoglycemia as compared to controls although glucose tolerance curves were normal. There was no fibrosis after pancreas- autotransplantation. This experimental model is useful for long term evaluation of heterotopic transplantation of the pancreas. Denervation and lymphatic interruption of the pancreas may cause a transient but not definitive influence on pancreatic endocrine or exocrine function.

    Notes: Abstract The elastic scattering of 140-MeV16O and 175- and 252-MeV20Ne from235U has been measured. Experimental ratios of elastic to Rutherford scattering cross sections are analyzed in terms of both Fresnel scattering and optical models. The radius parameters derived from these analyses are found to be nearly independent of projectile energy. Total reaction cross sections are obtained and found to be in good agreement with the total fission cross section for these systems. Comparisons between the Fresnel theory and the optical model give generally good agreement. A simple formula which parameterizes the total reaction cross section in terms of the interaction radius is presented for16O and20Ne reactions.Nuclear Reactions:235U(16O,16O),E=140 MeV;235U(20Ne,20Ne),E=175 MeV, 252 MeV; measuredσ el; compared with Fresnel and optical models; deduced maximum angular momenta, interaction radii, total reaction cross section.

    Notes: Abstract We report the measurement of the differential cross section of the reaction γ +p→π0 +p at a photon energy of 1.4 GeV and pion c.m. angles between 60 and 175 degrees. The angular distribution confirms the simple quark model prediction of a pure magnetic excitation of theF 37 (1950) resonance.

    Notes: Summary During the hatching period, the Rohon-Beard cells of Salmo gairdneri showed definite structural maturity of their perikarya, which is in contrast to the amphibian species investigated, where neuronal maturation of the Rohon-Beard cells is finished only in later — posthatching — developmental stages.

    Notes: Zusammenfassung Es wurde im vorstehenden ein bereits früher entwickeltes Näherungsverfahren zur Lösung von Eigenwertproblemen in seinen wesentlichen Grundlagen nochmals geschildert und seine Anwendung auf einige mechanische Probleme gezeigt. Die dabei verwandte Entwicklung von Eigenwertλ und Eigenfunktionu in eine Potenzreihe des „störenden“ Parametersα in der Form $$u = \upsilon _0 + \sum\limits_{i = 1,2,...} {\alpha ^i } \upsilon _i (z){\text{ }}und{\text{ }}\lambda = \lambda _0 + \sum\limits_{i = 1,2,...} {\alpha ^i \varepsilon _i } $$ zeigt, daß die erste Eigenwertsänderung ε1 unmittelbar durch eine einfache Quadratur gewonnen, daß dannv 1 aus einer inhomogenen Differentialgleichung, daraus wieder durch einfache Quadraturε 2 gefunden werden kann und so fort. Es lassen sich gegebenenfalls einfache Rekursionsformeln aufstellen. (Die Ermittlung der bestimmten Integrale kann bei umständlicheren Gesetzen oder graphisch gegebenem Gesetz der störenden Funktion mit dem Planimeter erfolgen; ebenso kann bei Lösung der inhomogenen Differentialgleichungen unter Benutzung der Methode der Variation der Konstanten der Integraph oder das Integrimeter vonOtt oder das Stieltjes-Integrimeter vonNyström benutzt oder graphisch integriert werden.) In manchen Fällen wird die Bestimmung des Einflusses vonα 1 ausreichen; dann gibt $$\varepsilon _1 = \left. {\frac{{\partial \lambda }}{{\partial \alpha }}} \right|_{\alpha = 0} $$ an, in welcher Richtung sichλ ändert, ob der Eigenwert steigt oder sinkt, und $$\upsilon _1 = \left. {\frac{{\partial u}}{{\partial \alpha }}} \right|_{\alpha = 0} $$ an, wie sich die Nullstellen der Eigenfunktion gegenüber denen des Nullproblems verschieben. Der Einfluß vonα 2 liefert $$\varepsilon _2 = \frac{1}{{2!}}\left. {\frac{{\partial ^2 \lambda }}{{\partial \alpha ^2 }}} \right|_{\alpha = 0} $$ und bestimmt damit die Krümmung der Kurveλ (α) fürα=0. Die Ermittlung vonε 2 empfiehlt sich besonders dann, wennε 1=0 ist. Dann hatλ(α) fürα=0, d. h. inλ 0 einen Höchst- bzw. Tiefstwert, je nachdemε 2〈0 oder 〉0 ist.

    Description / Table of Contents: Summary The authors report on the immuno electron microscopic demonstration of Concanavalin A-receptors on the erythrocyte membrane. Immuno freeze-etching studies evidenced a focal arrangement of Concanavalin A-receptors on intact erythrocytes as well as on erythrocyte ghosts. Obviously hemolysis by distilled water does not produce changes in the pattern of distribution of Concanavalin A-receptors whereas slight aggregation of plasma membrane intramembraneous particles occured. No unambigous spatial relationship between Concanavalin A-receptors and the plasma membrane intramembraneous particles (intrinsic proteins) of erythrocytes could be observed.
    Notes: Zusammenfassung Es wird über den immun-elektronenmikroskopischen Nachweis der Concanavalin A-Rezeptoren der Erythrozytenmembran berichtet. Die Immun-Gefrierätzungsuntersuchungen zeigten, daß die Concanavalin A-Rezeptoren sowohl der intakten Erythrozyten als auch der Erythrozytenschatten herdförmig verteilt sind. Die Aqua dest.-Hämolyse führt offenbar zu keiner Umverteilung der Concanavalin A-Rezeptoren, während eine geringfügige Aggregation der intramembranösen Partikeln der Plasmamembran eintrat. Eine eindeutige räumliche Beziehung der Concanavalin A-Rezeptoren zu den intramembranösen Partikeln (intrinsic proteins) der Plasmamembran der Erythrozyten konnte nicht beobachtet werden.

    Notes: Summary In recent years large numbers of the so-called “mucocutaneous lymph node syndrome” or “Kawasaki's disease” have been described by Japanese workers, but instances of this disorder are only now being reported as isolated cases by European or North American physicians. The disease has, therefore, been considered to be a new entity. One of its most striking features is the development of aneurysms of the coronary arteries in infants or children, which may lead to sudden death. Aneurysms of the coronary arteries in childhood are rare, and hence it was considered relevant to report six such cases, and to examine their possible relationship to Kawasaki's disease. The pathological changes underlying the latter disorder are not well known; they are considered to be indistinguishable from infantile polyarteritis nodosa. A diagnosis of polyarteritis nodosa was also thought to be most likely to apply in the cases presented here, particularly in view of the frequency with which aneurysms of the coronary arteries have been found in this disorder. In the absence of valid pathological distinctions between Kawasaki's disease and infantile polyarteritis nodosa, the question arises whether these entities are, in fact, different, and whether Kawasaki's disease is the new entity it is assumed to be.
