    Notizen: A double-blind group comparative trial comparing Opticrom with a matching placebo, over a four-week period, in seasonal allergic conjunctivitis is reported. Overall assessment of treatment benefit made at the end of the trial by the patients and the clinician showed a statistically significant difference in favour of Opticrom. Of the patients on Opticrom, eighteen (90%) said they improved while in the clinicians opinion, seventeen (85%) improved.Six patients using Opticrom and five using placebo complained of stinging of the eyes, while one patient using placebo complained of his eyes becoming bloodshot and watering.

    Notizen: Summary Endotoxin treated with chromium chloride is less toxic to mice than the parent molecule, but can disrupt intestinal permeability barriers and has an enhanced ability to activate Hageman factor.

    Beschreibung / Inhaltsverzeichnis: Zusammenfassung Die Entwicklung der Cephamycin-Antibiotika stellt einen großen Fortschritt in der Beta-Laktam-Chemie dar. Diese Antibiotika-Familie lieferte ein wichtiges Bauelement für die Synthese einer Gruppe von Antibiotika mit außergewöhnlich guter Beta-Laktamase-Festigkeit. Cefoxitin ist das erste klinisch anwendbare halbsynthetische Cephamycin. Umfangreiche In-vitro-Studien zeigen, daß Cefoxitin einen bedeutenden Fortschritt gegenüber den bisher verwendeten Beta-Laktam-Antibiotika aufweist. Es besitzt ein breiteres Wirkungsspektrum als die Cephalosporine und ist außerdem wirksam gegen viele Bakterienarten der indolpositvenProteus-,Serratia- undBacteroides-Gruppen, einschließlichBacteroides fragilis und dessen Arten. Die antimikrobielle Wirksamkeit von Cefoxitin umfaßt auch die BakteriengruppenEscherichia coli undKlebsiella, die gegen Cephalosporine resistent wurden. Das breitere Wirkungsspektrum kann größtenteils der beinahe absoluten Beta-Laktamase-Festigkeit zugeschrieben werden. Cefoxitin wirkt bakterizid, unabhängig von der Größe des Inokulums, und ist metabolisch stabil; es ist damit ein außergewöhnlich zuverlässiges Antibiotikum für den klinischen Gebrauch. Tierversuche mit Cefoxitin zeigten die hervorragende Korrelation zwischen der In-vitro- und In-vivo-Wirksamkeit. Große Wirksamkeit, hohe Sicherheit und Zuverlässigkeit machen Cefoxitin zu einem wertvollen Antibiotikum mit sehr breitem Spektrum.
    Notizen: Summary The discovery of the cephamycin family of antibiotics represents a major advance in beta-lactam chemistry. The family provided an important intermediate for the synthesis of a group of antibiotics with outstandingly good resistance to beta-lactamase. Cefoxitin is the first of these semisynthetic cephamycins to be made available for clinical use. Extensive laboratory studies show that cefoxitin provides a significant advance over currently in use beta-lactam antibiotics. It has a broader spectrum than the cephalosporins and, in addition, is active against many strains of indolepositiveProteus, Serratia spp. andBacteroides spp., includingBacteroides fragilis and all its subspecies. It is active against many strains ofEscherichia coli andKlebsiella that have become resistant to the cephalosporins. The broader spectrum can be accounted for in large measure by cefoxitin's almost complete resistance to a wide range of beta-lactamases. Cefoxitin is bactericidal, is unaffected by inoculum size and is metabolically stable; it is, therefore, a highly reliable antibiotic for usein vivo. Animal experiments have shown the excellent correlation betweenin vitro susceptibility andin vivo efficacy with cefoxitin. Excellent efficacy, safety and reliability of cefoxitin make this antibiotic useful in the treatment of a very broad range of infections.

    Notizen: The oxidative degradation of isotactic polypropylene films coated on well-defined Cu(Cu2O), CuO0.67, and CuO films in a temperature range of 90-120°C in a quartz-spoon-gauge-reaction vessel was studied. This catalytic reaction has been compared with the oxidation of polypropylene without copper or oxide films. The reaction vessel contained, if needed, P2O5 and/or KOH as “getters” for H2O and CO2, these substances could be menitored continuously. Cu(Cu2O) films were transformed during oxidation of the polymer to yellow CuO0.67 below 100°C and above this temperature to black CuO in the presence of H2O and CO2, whereas in the absence of these compounds CuO was formed below 100°C and CuO0.67 at 120°C. Characteristic autoxidation curves obtained in the absence of H2O and CO2 showed induction periods that were shorter for copper oxide-polymer interfaces than for glass-polymer interfaces (i.e., for uncatalyzed oxidation). Abnormalities were observed for Cu(Cu2O)-polymer interfaces because of further oxidation of Cu during the reaction. The rates of oxygen consumption were faster for CuO0.67-polymer and CuO-polymer than for the uncatalyzed reaction; the catalytic action of CuO0.67 was somewhat larger than that of CuO. The important observation was made that the mechanism of oxidation is not the same in the absence and presence of reaction products; that is, H2O and CO2. This was confirmed by ion beam scattering experiments, which also revealed that an oxidation-reduction process takes place at Cu and their oxide interfaces. A mechanism for the catalytic oxidation process, based on the ease by which copper ions are released from the metal oxides at the interface, was formulated. These ions diffuse subsequently as actions of carboxylate anions into the bulk of the polymer. Arrhenius equations of oxygen consumption are given for all cases; the energy of activation calculated for the initiation of the uncatalyzed oxidation agrees with its literature value. The energy of activation for the initiation of the catalyzed reaction was a few kilocalories lower than that for the uncatalyzed reaction. Catalytic action is mainly operative for the initiation reaction at the interface and for the decomposition of hydroperoxides by copper ions. Preventing the delivery of copper ions to the polymer would be the most efficient way of inhibiting the catalysis.
