    Notes: The morphology of the lipid phase and resistance to penetration of different brands of commercial wieners, ring bologna and braunschweiger were studied. Even though consistent results were not obtained from all products, it was suggested that products with a smaller lipid globule size had a greater resistance to penetration.

    Notes: Abstract The linear heat transport of helium II contained in porous powder samples with mean pore diameters of 1.25µm, 0.17µm and 0.02µm was systematically studied in the temperature range between 0.8 K and 2 K. The effective thermal conductivity was determined by steady-state heat flow measurements and the effective thermal diffusivity by transitory temperature measurements. The experimental results are interpreted by a simple theoretical model. In the framework of this model the linear heat transport consists of two contributions: the laminar flow of the normal fluid (T≳1.4 K) and a diffusion mechanism (T≲1.4 K). At low temperatures (T≲1.2 K) the mean free paths of the elementary excitations of helium II become greater than the pore diameters. In this range, the heat flow is limited by scattering of the elementary excitations with the walls of the pores and can be described by a kinetic model. Good agreement between theory and experiment is obtained in the total temperature range investigated.

    Description / Table of Contents: Zusammenfassung Ein 15jähriger Patient mit idiopathisch-thrombozytopenischer Purpura, die sich gegen Corticosteroid-Behandlung, Splenektomie und immunsuppressiver Therapie mit Vincristin als resistent erwies, wurde mit Thrombozyten-Vinblastin-Komplex behandelt. 5 Tage nach der Applikation dieses Komplexes zeigte sich ein Anstieg der Thrombozyten, der nach Wiederholung der Therapie mit autologem Thrombozyten-Vinblastin-Komplex andauerte und bis zu 600 × 109 Thrombozyten/Liter ging. Die Remission dauert auch 15 Wochen nach Therapiebeginn noch an. Außer einer passageren Granulozytopenie zeigten sich keine Nebenwirkungen.
    Notes: Summary A 15-year-old patient with ITP which was refractory to corticosteroids, splenectomy, and immunosuppressive therapy with vincristine was twice treated with platelets loaded with vinblastine. Five days after the application of the platelets vinblastine complex the platelets began to rise up to 600 × 109/1. The remission has lasted until now for more than 15 weeks. The therapy showed no major side effects except for a transient granulocytopenia.

    Notes: Abstract Induction by light of phenylalanine ammonia-lyase (PAL; EC 4.3.1.5) and of anthocyanin in cotyledons of the mustard (Sinapis alba L.) seedling is strongly affected by a light pretreatment which operates through phytochrome. If PAL or anthocyanin is induced by a light pulse, the effectiveness of phytochrome (Pfr) is strongly increased by a light pretreatment; however, if the increase of the PAL level or synthesis of anthocyanin is elicited by continuous far-red light (operating via phytochrome in the ‘High Irradiance Response’), effectiveness of light is strongly reduced by the same light pretreatment. This reduction of effectiveness is correlated with a decrease of total phytochrome (Ptot) caused by the light pretreatment. It is argued that the observations are compatible only with the ‘open phytochrome-receptor model’ as suggested by Schäfer (J. Mathem. Biol. 2, 41–56, 1975). The peaks of the time courses of the PAL levels under continous far-red light are located at 48 h after sowing and do not depend on the original level of phytochrome. The decrease of the PAL levels beyond 48 h after sowing takes place independently of phytochrome and of the actual level of PAL.

    Description / Table of Contents: Zusammenfassung Phorbol und sechs strukturverwandte Substanzen, die die polyfunktionellen Diterpene des Tiglian-, Ingenan- und Lathyrantyps repräsentieren, wurden an SWR-Mäusen auf systemische promovierende und leukämogene Wirkung geprüft. Zur systemischen Initiation wurde kurz nach Geburt 15 μg Dimethylnitrosamin (DMN) s.c. injiziert. Die Diterpene wurden i.p. entweder mit oder ohne vorhergehende Initiation mit DMN gegeben. Systemische Promotion für Leber zeigten alle geprüften Diterpene mit der Entstehung von Adenomen. Einige der Diterpene erwiesen sich wirksamer als Phorbol. Die relativ hohe Dosis von DMN, die als Initiator verwendet wurde, machte eine Auswertung bezüglich promovierender Wirkung auf die Lunge unmöglich. Die leukämogene Wirkung von Phorbol bei SWR Mäusen wurde für drei verschiedene Dosen bestätigt. Die übrigen Diterpene zeigten mit der jeweils geprüften Dosis keine signifikante leukämogene Wirkung. Die leukämogene Wirkung des Phorbols wurde durch vorausgehende DMN-Injektion vollständig verhindert. Die fehlende Korrelation zwischen promovierender Wirkung an Haut, systemischer promovierender Wirkung an Leber und leukämogener Wirkung der getesteten Diterpene wird diskutiert.
    Notes: Summary Phorbol and six structurally related compounds representing the polyfunctional diterpenes of the tigliane, ingenane, and lathyrane types were tested for systemic promoting and leukemogenic activity in SWR mice. For systemic initiation soon after birth, 15 μg dimethylnitrosamine (DMN) was injected s.c. The diterpenes were administered i.p. either with or without prior systemic initiation with DMN. Systemic promotion was expressed for liver by induction of adenomas with all the diterpenes tested, some of them being more potent than phorbol. The relatively high dose of DMN used as initiator prevented an evaluation of promoting action in relation to lung carcinogenesis. The leukemogenic effect of phorbol in SWR mice was confirmed at three different dose levels. The other diterpenes tested had no significant leukemogenic activity. The leukemogenic action of phorbol was totally inhibited by prior DMN injection. The lack of correlation between promoting action in skin, systemic promoting action in liver and leukemogenic action, among the diterpenes tested, is discussed.

    Notes: Abstract We present a study of two-particle correlations in proton-emulsion nucleus reactions at 400 GeV. In particular the correlations at different nuclear excitations and different rapidity regions are treated. Positive correlations, depending on nuclear excitation, are observed in the rapidity region η〈1.5.

    Description / Table of Contents: Zusammenfassung Ein Verfahren für die quantitative Bestimmung von Sterigmatocystin in pflanzlichen Nahrungsmitteln durch zweidimensionale DC-Trennung eines Extraktes und Fluorescenzintensitätsmessung der mit AlCl3 behandelten DC-Platte wird beschrieben. Durch die hier vorgeschlagene Auftrageweise auf der DC-Platte ist ein rasches Identifizieren und Auswerten von Probe- und Eichflecken möglich. Als Extraktionsmittel hat sich Acetonitril-KCl-Lösung am besten bewährt. Versuche mit zugesetztem Toxin zeigten Verluste von weniger als 5 %.
    Notes: Summary The quantitative determination of sterigmatocystin is achieved by two-dimensional thin-layer chromatography (TLC) of extracts from vegetable foods and measurement of the fluorescence of the spots on AlCl3-treated TLC plates. Samples and controls (references) are applied to the TLC plates in a way that permits their quick identification and assay. Acetonitrile-KCl solution has proved to be the most advantageous extracting agent. Losses of less than 5 % were observed in tests with added toxin.
