    Description / Table of Contents: Zusammenfassung Berichtet wird über den ungewöhnlichen Verlauf eines Morbus Whipple. Unter antibiotischer Therapie tritt klinisch eine völlige Beschwerdefreiheit ein. Mehrfache Kontrollbiopsien zeigen eine hochgradige und progrediente Kollagenisierung des Stratum proprium mucosae, die besonders auch pericellulär und im Bereich der epithelialen Basalmembran entwickelt ist. Lymphocyten, Plasmazellen und interepitheliale lymphoide Rundzellen sind stark vermehrt. Immunologisch ist Serum-Komplement (C3-Fraktion) erniedrigt. Immunhistologisch findet sich nach Inkubation mit Patientenserum eine cellulär-cytoplasmatische Fluorescenz mit Anti-Komplement von subepithelial und interepithelial gelegenen Zellen. Die Befunde werden im Sinne eines hyperreaktiven Vorganges, der möglicherweise zur Induktion eines cellulären Immunmechanismus geführt hat, diskutiert.
    Notes: Summary An unusual course of Whipple's disease is reported. All clinical symptoms disappear with antibiotic therapy. Multiple control biopsies show a high grade and progressive collagen formation of the stratum proprium mucosae which takes places especially in the pericellular region and near the epithelial basal membrane. The number of lymphocytes, plasma cells and interepithelial lymphoid round cells is increased considerably. Immunologically the serum complement (C3-fraction) is decreased. Immunohistologically subepithelially and interepithelialy situated cells are found after incubation with the patients serum showing a cellular-cytoplasmatic fluorescence with anti-complement. These findings are discussed as a hyperreactive mechanism possibly leading to induction of a cellular immune process.

    Notes: Abstract In an investigation ofT=7/2 analogue states in51V the50Ti(p, γ) excitation curve has been measured for proton bombarding energies 1280–1480 keV and 2340–2660 keV. From the (p, γ) resonances 29 new virtual levels in the region of 9316–9510 keV excitation energy in51V were determined. The strong resonance atE p=1 371 keV has been identified as the isobaric analogue state of the51Ti ground state by determining spin and parity of this resonance to be 3/2−. There is no evidence for a strong analogue resonance in51V corresponding to the 1.16 MeV p 1/2 state in51Ti. The γ-decay of the p 3/2 analogue state has been studied by measuring branching ratios and angular distributions of primary γ-transitions with a Ge(Li) detector.M1E2 mixing ratios have been determined for these transitions. The total width of the resonance for γ-decay is found to be Γγ=1.6±0.4 eV. New bound levels in51V have been introduced at 3576, 4651 and 4661 keV excitation energy. TheJ π values of the 3085, 4770, and 4863 keV states are determined to be 5/2−, 5/2−, 3/2−, respectively. The analogue-antianalogueM1 transition strength is found to be considerably reduced compared to the situation ins-d shell nuclei.

    Description / Table of Contents: The thermal polymerisation of styrene produces small amounts of dimeric and trimeric adducts as by-products. For pure styrene, these are mainly saturated, cyclic compounds. Kinetic investigations show that two independent reactions occur: in the first, 1.2 - diphenylcylobutanes are produced by cycloaddition, whilst in the second, four saturated trimers are formed from an intermediate DIELSALDER adduct, as postulated by MAYO.
    Notes: Bei der thermische Styrolpolymerisation entstehen als Nebenprodukte geringe Mengen an Dimeren und Trimeren. In reinem Styrol handelt es sich überwiegend um cyclische, gesättigte Verbindungen. Kinetische Messungen zeigen, daß zwei voneinander unabhängige Reaktionen ablaufen: In einer Cycloaddition werden 1.2- Diphenylcyclobutane gebildet, Während vier gesättigte Trimere über das von MAYO formulierte DIELS-ALDER-Addukt entstehen.
