    Description / Table of Contents: Zusammenfassung Amöbenabscesse der Leber treten in 90% bei Männern und zu 85 % im rechten Lappen auf. Klinisch imponieren Sepsis, Schmerzen, Hepatomegalie und pulmonale Komplikationen. Die Diagnose wird serologisch gesichert. Die Therapie ist zunächst konservativ. Mischinfektionen, Ruptur, Lokalisation im linken Lappen und erfolglose Therapie sind Operationsindikationen. Amöbome, hypertrophisch-granulierende Colontumoren bei chronischer Amöbencolitis finden sich zu 40% im Caecum, zu 30% im Rectosigmoid. Benigne Histologie und Amöbennachweis sichern die Diagnose. Bis auf Komplikationen konservative Therapie.
    Notes: Summary Of amebic hepatic abscesses, 90 percent occur in males, and 85 percent in the right lobe. Sepsis, pain and hepatomegaly, and, in 50 percent of cases, pulmonary complications dominate the clinical picture. Diagnosis is established by serological methods. The initial treatment is conservative. Pyogenic infection, rupture, left-lobe abcess, and lack of response call for surgical intervention. Forty percent of amebomas, rare hypertrophic colonic tumors occurring in chronic amebic colitis, are found in the cecum, and 30 percent in the rectosigmoid. The diagnosis depends on benign histology and the demonstration of amebae. Treatment is conservative unless there are complications.

    Notes: The binding of iodinated basic fibroblast growth factor (bFGF) to low-density heparan sulfate proteoglycan purified from the Engelbreth Holm Swarm (EHS) sarcoma was investigated using different techniques. The tumor clearly contained bFGF, the level being comparable to that found in other tissues such as human or bovine brain. 125I bFGF strongly bound to the basement membrane-like matrix of EHS frozen sections as revealed by autoradiography. Iodinated bFGF bound to purified heparan sulfate proteoglycan but not to laminin or collagen type IV, three components isolated from the same tumor. In contrast, acidic fibroblast growth factor (aFGF) displayed negligible binding to heparan sulfate proteoglycan. Binding of bFGF to frozen sections and to purified proteoglycan could be strongly inhibited by heparin and was displaced by an excess of unlabeled factor and completely suppressed after heparitinase and heparinase treatments. Binding was a function of the salt concentration and was abolished at 0.6 M NaCl. Scatchard analysis indicated the affinity site had a Kd of about 30 nM, a value 10-15 higher than that recently reported by Moscatelli (J. Cell. Physiol., 131:123-130, 1987) in the case of the low-affinity binding sites present on the surface of baby hamster kidney (BHK) cells.

    Description / Table of Contents: Chlorinated polypropylenes with a chlorine content between 3 and 72.3% by wt. as well as chlorosulfonated polypropylenes with a chlorine content between 3 and 54.4% by wt. and a sulfur content between 1.2 and 5.9% by wt. are prepared by means of chlorination and chlorosulfonation of atactic polypropylene in solution. The influence of substitution von molecular weight, intrinsic viscosity, glass transition temperature as well as dynamic-mechanical behaviour and thermal short-time behaviour of the polymers is investigated.
    Notes: Durch Chlorierung und Sulfochlorierung von ataktischem Polypropylen in Lösung werden gezielt chlorierte Polypropylene mit 3 bis 72,3 Masse-% Chlor und einem Schwefelgehalt von 1,2 bis 5,9 Masse-% dargestellt. Es wird der Einfluß der Substitution auf die rel. Molekülmasse, Grenzviskosität und Glasübergangstemperatur sowie das dynamisch-mechanische Verhalten und das thermische Kurzzeitverhalten der Polymere untersucht.

    Description / Table of Contents: Using the managers(IV)-method methyl methacrylate was grafted onto potato starch and dextran as well as 1-acryloyl-3-methylpyrazole and 1-methacryloyl-3,5-dimethyl-pyrazole onto potato starch. The graft copolymerization of potato starch with methyl methacrylate was investigated with respect to the influences of the acid concentration, the solvent composition, the presence of permanganate, and the gelatinization of starch.
    Notes: Nach der Mangan(IV)-Methode wurden Methylmethacrylat auf Kartoffelsärke und Dextran sowie 1-Acryloyl-3-methyl-pyrazol und 1-Methacryloyl-3,5-dimethyl-pyrazol auf Kartoffelstärke gepfropft. Für die Pfropcopolymerisation von Kartoffelstärke mit Methylmethacrylat wurde der Einfluß der Säurekonzentration, der Lösungsmittelzu sammensetzung, der Anwesenheit von Permanganat und der Gelatinierung der Stärke untersucht.

    Description / Table of Contents: Polymer bound microbiocides are prepared by 4-dimethylaminopyridine catalyzed acylation of cellulose and cellulose dibenzylether with the thio acid chloride obtained from 3-methyl-pyrazole and thiophosgene. The hydrolytic release of the bioactive compound is controlled primarily by the hydrophilicity of the polymer support and the state of swelling and dissolution of the polymer-biocide-combination and its change during hydrolysis.
    Notes: Polymergebundene Mikrobiocide werden durch Acylierung von Cellulose und Cellulosedibenzylether mit dem aus 3-Methyl-pyrazol und Thiophosgen erhältlichen Thiocarbonsäurechlorid unter Katalyse mit 4-Dimethylamino-pyridin hergestellt. Die hydrolytische Wirkstoffreisetzung wird primär über die Hydrophilie der Trägerpolymere sowie den Quellungs- bzw. Lösungszustand der Polymer-Wirkstoff-Kombination und seine Änderung während der Hydrolyse gesteurt.
