    Notes: Summary A facial flush provoked by alcohol in chlorpropamide treated diabetics has been described as a genetic marker for a dominantly inherited type of non-insulin dependent diabetes. In this study a chlorpropamide alcohol flush was observed in 16.9% of control subjects (n=154), 23.3% of insulin dependent diabetics (n=437) and 16.5% of patients with non-insulin dependent diabetes (n= 145). Among the non-insulin dependent diabetics no difference in the frequency of the chlorpropamide alcohol flush was found between those with and without a family history of diabetes. Specificity was not improved by skin temperature measurement or additional placebo tests. According to these data the chlorpropamide alcohol flush does not seem to be specific for non-insulin dependent diabetes and hypotheses about the aetiology of this type of diabetes based on the chlorpropamide alcohol flush should be regarded with caution.

    Description / Table of Contents: Studies on Oxide Catalysts. XXXVII. On the Influence of Preparation Conditions on the Properties of Silica-AluminaSilica-alumina samples of different composition were prepared by coprecipitation from aqueous solutions at pH = 6 and pH = 9, respectively. Structures and properties of the solids were characterized (i.r., DTA, X-ray, molybdato method, surface acidity, catalytic activity in the cracking reaction of cumene). Solid composition and pH value of the precipitation medium equally exhibit influence on the structure of the silica-alumina (kind of incorporation of the aluminium) and thereby on the acidic and catalytic properties of the solids. Silica-alumina of equal composition but precipitated at different pH values may widely differ in their properties including activity-composition dependency.
    Notes: Durch Mischfällung wurden aus wäßrigem Medium bei pH = 6 bzw. pH = 9 röntgenamorphe Al2O3—SiO2-Festkörper unterschiedlicher Zusammensetzung hergestellt. Aufbau und Eigenschaften der Festkörper wurden charakterisiert (IR, DTA, Röntgendiffraktometrie, Molybdatmethode, Oberflächenacidität, katalytische Aktivität in der Spaltung von Cumen). Zusammensetzung und pH-Wert des Fällmediums beeinflussen gleichermaßen den Aufbau des Al2O3—SiO2 (Art des Einbaus des Aluminiums) und damit dessen acide und katalytische Eigenschaften. Al2O3—SiO2-Proben gleicher Zusammensetzung können unterschiedliche Eigenschaften aufweisen, wenn sie bei unterschiedlichen pH-Werten gefällt wurden. Das trifft auch auf die Form der Abhängigkeit der katalytischen Aktivität von der Zusammensetzung zu.
