    Notes: Summary Alpha-1-microglobulin (alpha-1-m) is a low molecular weight glycoprotein (mw 25–33 KD) that is filtered through the glomeruli and reabsorbed in the proximal parts of the renal tubules where it is catabolized. Normal ranges were established for alpha-1-m (100 healthy controls) in serum (20–42 mg/l) and urine (3.5–8 mg/l). Alpha-1-m was then measured in 341 urine samples whose protein pattern had been classified as “pathologic” and “normal” according to microelectrophoresis. Increased alpha-1-m concentrations were found in 266 out of 280 pathologic urines (5% false negative) and in 3 out of 61 normal urines (4% false positive). Beta-2-microglobulin (beta-2-m), total protein or protein test strips showed a poorer correlation to the electrophoretic results. Measurement of alpha-1-m is, therefore, the most sensitive of these methods for the detection of proteinuria. In 90 patients with low molecular weight proteinuria and either with or without renal insufficiency alpha-1-m concentrations were determined in both urine and serum. While all patients had elevated urinary alpha-1-m concentrations, increased serum values were only found in renal insufficiency (Ccrea〈100 ml/min). Independently of these results, we were also able to establish that increased alpha-1-m levels are found at decreased glomerular filtration rates (Ccrea 〈70 ml/min). Pathologic alpha-1-m concentrations therefore only allow the conclusion of isolated tubular impairment when the GFR is greater than 70 ml/min. Data from 350 patients with various renal and hypertensive diseases showed that serum alpha-1-m is a more sensitive indicator of renal insufficiency, even in the so-called “creatinine blind” range (60–100 ml/min) of the GFR than either creatinine or beta-2-m.

    Notes: Abstract Investigations were carried out by means of an autologous, heterotopic model for kidney transplantation applied to dogs. Duration of cold ischemia was 48 h. Four experimental groups were arranged. During the first 20 min following revitalization of the transplanted kidney, group 1 (HTK solution/80 cm perfusion height) showed a significant glomerular and tubular malfunction. In group 2 (HTK solution/120 cm perfusion height), only four urinary proteins with molecular weights of 25 kDa, 67 kDa, 100 kDa and 〉100 kDa were found. The excretion of higher molecular proteins receded over the 20-min period of observation. In both group 3 (HTK/aspartate solution) and group 4 (HTK/tryptophan solution) the quantity of excreted glomerular and tubular protein was well above that of group 2. As opposed to the “Tryptophan” group, a complete restoration of renal function was observed in the “Aspartate” group after 4 weeks. In general, the “standard” HTK protective solution delivered with 120 cm perfusion pressure gave the most favorable results, with the lowest levels of proteinuria and a satisfactory recovery of renal function after revitalization.

    Notes: Abstract Abstract We report on a 13-month old boy with microcephalic osteodysplastic primordial dwarfism (MOPD), whose radiographic signs correspond with type II of this entity. Some of his clinical signs, such as the anomalies of the external genitalia and the urinary tract, are common to this subgroup of MOPD, but he also shows unusual clinical signs including bilateral knee dislocation and hypoplasia of the anterior corpus callosum. His clinical course was unusual with several episodes of breathing difficulties and increased intracranial pressure secondary to craniosynostosis at the age of 16 months. After fronto-orbital advancement for the treatment of brachycephaly, his psychomotor development improved remarkably. Conclusion MOPD type II may have a wider range of expression than previously delineated.

    Urinary protein electrophoresis profile in normal and hypertensive pregnancies (1989)

    Notes: Summary By using of modified urine preparation and a highly sensitive SDS-polyacrylamide gel electrophoresis (SDS-PAGE) we determined the urinary protein profile in 21 healthy males, 25 healthy females, 64 patients with uncomplicated pregnancy and 110 hypertensive pregnant women. The urinary protein patterns were similar in controls and in women with a normal pregnancy. There were no increase in the number of protein bands from the 1st trimester to term, and the electrophoresis pattern did not change in the postpartum period. In both groups, an intensively stained protein band with an apparent molecular weight of 105 kD was detected. The 105 kD band was significantly reduced or completely absent in 91 (83%) out of 110 hypertensive pregnant women. The urinary protein electrophoresis profile correlated significantly with the severity of the disease. The 105 kD band disappeared just before or simultaneously with the onset of clinical symptoms in 18 out of 32 hypertensive pregnant women followed throughout pregnancy. Postpartum the 105 kD in urine reappeared at 2 to 14 days after delivery in 49 of the 53 patients. Using a silver staining and Western blot, the 105 kD band was identified as Tamm-Horsfall protein, which is identical to the immunosuppressive glycoprotein uromodulin. The findings in the SDS-PAGE may reflect a transitory tubular dysfunction in cases of pre-eclampsia, which is usually reversible after delivery. The results of our study support the hypothesis of an immunological basis for this disorder.

    Notes: Liquid Crystals with Aliphatic Groups between Cyclohexane Rings - Synthesis of 1,4-Bis(4-n-alkylcyclohexyl)butanes and Esters of 4-[4-(4-n-Alkylcyclohexyl)-butyl]cyclohexanolsThe synthesis of 1,4-bis-(4-n-alkylcyclohexyl) butanes (1), esters of 4-[-(4-n-alkylcyclohexyl)butyl]cyclohexanols (2) and some analogous aromatic compounds are described. The thermal stability of mesophases of these compounds are in the order of the analogous ethylene-bridged liquid crystals. The reason for this result seems to be the combination of molecular rigidity and conformational flexibility.

Modification of the Catalytic Behavior of Modified ZSM-5 Zeolites by Thermal TreatmentThe catalytic activity, the shape selectivity, and the deactivation behavior of ZSM-5 in paraffin cracking reactions can be regulated by a thermal pretreatment. A minimum of the deactivation rate as a function of zeolite pretreatment time at 600°C found in the hexane cracking could be verified in the methanol conversion reaction to gasoline.
    Notes: Die katalytische Aktivität, die Formselektivität und das Aktivität-Zeit-Verhalten des ZSM-5 beim Spalten von Paraffinen kann durch thermische Vorbehandlung stark beeinflußt werden. Ein in der Spaltung von Hexan gefundenes Minimum der Desaktivierungsgeschwindigkeit als Funktion der Dauer der Vorbehandlung bei 600°C konnte in der Methanolumwandlung zu Benzin verifiziert werden.

    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.
