    Notes: Abstract A case of successful obliteration of a bleeding splenic artery pseudoaneurysm secondary to necrotizing pancreatitis is reported. The material used for embolization was stainless steel coils. A variation of the technique is introduced. Instead of occluding the pseudoaneurysm cavity itself, embolization only of the afferent vessel is advised.

    Description / Table of Contents: Summary Beginning on the 25th day of life and for 2 weeks thereafter Sprague-Dawley rats were fed a casein diet containing 10% of gum guar. The animals were given.14C algal protein or14C algal protein hydrolysate by stomach tube and the radioactivity in some tissues and tissue proteins was determined 3 h after the application. Radioactivity in blood and in respiratory CO2 was measured up to 3 h and 6 h, respectively, after the application. The results indicate no effect of gum guar on the utilization of the protein or of the amino acids of the protein hydrolysate.
    Notes: Zusammenfassung Sprague-Dawley-Ratten wurden ab dem 25. Lebenstag 14 Tage lang mit einer Caseindiät mit einem Zusatz von 10% Guarmehl gefüttert. Den Tieren wurde14C-Algenprotein oder Hydrolysat von14C-Algenprotein per Magensonde verabreicht und die Radioaktivität in einigen Geweben und Gewebeproteinen 3 h nach Tracerapplikation bestimmt. Radioaktivität im Blut wurde bis zu 3 h und im Atmungs-CO2 bis zu 6 h nach Versuchsbeginn gemessen. Die Ergebnisse zeigen keinen Einflu\ des Guarmehls auf die Verwertung des Proteins oder der Aminosäuren des Proteinhydrolysats.

    Description / Table of Contents: Summary A pulverized mixture ofAgaricus species known to accumulate cadmium, mixed 15∶85 with standard rat diet, was fed to a group of growing rats. The mixture contained 3.87 μg Cd/g dry weight. A control group received the standard rat diet alone (0.08 μg Cd/g). During the feeding period of 6 weeks the animals of both groups excreted about 90 % of the ingested cadmium in the faeces. In comparison to the control group, the experimental group accumulated much more cadmium in liver, kidneys, and remaining carcass. While it is concluded that the bioavailability of cadmium contained in mushrooms is not less than that of cadmium contained in other feeds and foods, most mushroom species do not contain more cadmium than other vegetables. In humans the average cadmium intake from the total diet is considerably below the tolerable level. Generalized warnings against consumption of mushrooms are therefore not considered necessary.
    Notes: Zusammenfassung Eine pulverisierte Mischung verschiedener als Cadmiumsammler bekannterAgaricus-Arten wurde 15∶85 mit Standard-Rattenfutter wachsenden Ratten verabreicht. Die Mischung enthielt 3,87 μg Cd/g Trockengewicht. Eine Kontrollgruppe erhielt das Standard-Futter allein (0,08 μg Cd/g). Während der 6wöchigen Fütterungsperiode schieden die Tiere beider Gruppen etwa 90 % des aufgenommenen Cadmiums in den Fäzes aus. Im Vergleich zur Kontrollgruppe akkumulierte die Versuchsgruppe viel mehr Cadmium in Leber, Nieren und Restkörper. Obwohl hieraus der Schluß zu ziehen ist, daß die Bioverfügbarkeit des in Pilzen vorhandenen Cadmiums nicht geringer ist als die des in anderen Lebens- und Futtermitteln vorhandenen Cadmiums, werden Empfehlungen an die Verbraucher, den Pilzverzehr einzuschränken, nicht für erforderlich gehalten, da zum einen die durchschnittliche Cadmiumbelastung aus der Gesamtnahrung erheblich unter dem gesundheitlich bedenklichen Wert liegt und da zum anderen die Cadmiumgehalte der meisten Pilzarten diejenigen anderer Gemüse nicht überschreiten.

    Notes: The origin of inelastic scattering in ISS spectra at low energy ratios (E/E0 ≤ 0.3) is discussed, and a description of results from ISS and XPS experiments on well-characterized Co/ZSM-5 catalysts after calcination in air and reduction in H2, H2 + CO, or CO is given. These treatments show that the chemisorption of hydrogen on highly dispersed metallic Co and Fe causes shielding of the metal from ISS detection. Additionally, the presence of hydrogen, whether in a chemisorbed form or in other forms such as hydrocarbons or H2O, affects significantly the intensity of the inelastic scattering.

    Notes: The Raman spectra of a series of WO3—AI2O3 catalysts containing 1-30 wt-% of WO3 were investigated with respect to the effect of O2 calcination and H2O—D2O exposure. These studies showed that the frequencies of bands due to surface tungstate species can be shifted reversibly by as much as 6% of their values during alternate O2 calcination and H2O exposure cycles. The exchange of 18O for l6O in the surface tungstate was also investigated with Raman spectroscopy and ion-scattering spectrometry. The results were used to assign Raman bands to fundamental vibrations of the surface tungstate and to propose a mechanism of interaction between H2O and the surface tungstate that hitherto has not been addressed for WO3—AI2O3.
