    Notes: Summary Three cases with renal angiomyolipoma in Bourneville's disease are reported. In two patients advanced renal insufficiency developed, one being treated by chronic intermittent hemodialysis. In the third patient rupture of angiomyolipoma with severe retroperitoneal bleeding occurred. In one patient, tumorous enlargement initially was diagnosed only in the right kidney and preceded angiomyolipoma of the left kidney for several years. In this patient nephrectomy was performed because malignancy was assumed before diagnosis of Bourneville's disease was established. Occasionally, histology may suggest sarcomatous changes. However, the absence of distant metastasis and the overall long survival of patients with renal angiomyolipoma in Bourneville's disease underline the benign character of the tumor. Treatment should be conservative because surgical intervention with loss of kidney parenchyma may enhance progression to end-stage renal failure.

    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.
