    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.

    Description / Table of Contents: Zusammenfassung Durch Versuche an 73 GrCh-Kaninchen wird belegt, daß homologe und heterologe (bovine) Photoreceptor-Außensegmente (ROS) klinisch gleichartige Chorioretinitiden induzieren. Die Befunde vermitteln Hinweise zur Lokalisation und zum Wirkungsgrad des homologen und heterologen (bovinen) pathogenen Antigens.
    Notes: Summary Experiments with 73 GrCh rabbits showed, that both homologous and heterologous (bovine) photoreceptor outer segments (ROS) induce chorioretinitic diseases of the same kind. The findings refer to questions of localization and efficiency of homologous and heterologous (bovine) pathogenic ROS antigens.

    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 fission fragment angular distributions from reactions of 140-MeV4He ions with238U,209Bi and197Au have been studied. From the anisotropies in the angular distributions, values forℊ eff, the effective moment of inertia at the fission saddle point, have been estimated and compared with results obtained at lower bombarding energies. The derivation ofℊ eff values has included corrections for the effects of incomplete fusion mechanisms on the orbital angular momentum distribution of the fissioning nuclei and for neutron evaporation prior to fission. The results are also compared with heavy-ion-induced fission data for systems of similar fissility. Also, examination of the forward-backward symmetry of the238U angular distribution substantiates other results which show that the fraction of fission reactions which follow complete fusion of the target and projectile is less than 0.5 for 140-MeV4He-ion bombardment of238U.
