    Description / Table of Contents: Zusammenfassung Salben mit Griseofulvin respektive Proquazon wurden aus Monoglyceriden mittlerer Kettenlänge und einem aprotischen Lösungsmittel, Glycerinformal, hergestellt und auf dem Rücken von Gallefistelratten appliziert. Die percutan resorbierten Mengen sowie die Permeabilitätskonstanten sind für beide Wirkstoffe wesentlich höher nach Applikation der Salben als nach Applikation von einfachen Wirkstofflösungen ohne Monoglyceride. Die Verteilung der markierten Wirkstoffe in Rattenhaut wurde durch Mikroautoradiographie kontrolliert. Die Konzentrationen der Wirkstoffe in den einzelnen Schichten von menschlicher Haut sowie die mittleren Penetrationsraten wurden 16 h nach Applikation der Salben auf isolierte menschliche Haut bestimmt. Monoglyceride mittlerer Kettenlänge erhöhen die Permeabilität des Stratum corneum für gelöste Wirkstoffe wesentlich.
    Notes: Summary Ointments containing griseofulvin and proquazone, respectively, were made up of monoglycerides of medium chain length and an aprotic solvent, glycerinformal. The ointments were applied topically on the back of bile cannulated rats. The total amount absorbed percutaneously and the permeability constants of both drugs were considerably higher for the ointments than for simple solutions of the drugs without monoglycerides. Distribution of the labeled drugs in rat skin has been demonstrated by microautoradiography. Concentrations of the drugs in the different layers of human skin together with the medium flow rates have been determined 16h after administration of the ointments onto isolated human skin. Monoglycerides of medium chain length enhance significantly the permeability of the stratum corneum for solutes.

    Notes: Summary A working group on Evaluation of Occupational Health and Industrial Hygiene Services (OHS) met in Stockholm in April 1980. The conference was organised by the Regional WHO-Office in cooperation with the government of Sweden. The participants of this meeting, in spite of the severe differences in the health systems of their countries, came to some conclusions for the definition of the OHS-goals and about the needed proceedings for evaluation of OHS on national bases. Recommendations for member countries of WHO in Europe for use in a coming plenary session of this board were also worked out.

    Topics: Medicine
    Notes: Summary The agonistic and antagonistic effects of the new compound SCH 23390 were tested in functional model systems for the D-1 dopamine receptor and for the D-2 dopamine receptor in vitro. In superfused rat neostriatal slices the increase in the efflux of cyclic AMP was used as a parameter for D-1 receptor stimulation. D-2 receptor stimulation was measured as the decrease in the K+-evoked release of [3H]-acetylcholine. SCH 23390 had no agonistic activity in these two models. SCH 23390 was a potent antagonist of the stimulating effect of dopamine in the D-1 receptor model (apparent pA2=7.28). SCH 23390 also antagonized the effect of the D-2 receptor agonist LY 141865 in the D-2 receptor model (apparent pA2=6.34). This D-2 receptor antagonism proved to be of a competitive nature.

    Description / Table of Contents: Zusammenfassung Eine im Auftrag der Gesellschaft für Technische Zusammenarbeit (GTZ) durchgeführte forstliche Reise nach Nordchina gab Anlaß, über einige der dabei erhaltenen Eindrücke und Kenntnisse zu berichten. Nach einer kurzen Darstellung der forstlichen Ausgangslage wird eine Übersicht über die wichtigsten beobachteten oder von chinesischer Seite aus erwähnten Schadinsekten, Schadwirbeltiere und Waldkrankheiten gegeben. Die Abwehrmaßnahmen im Rahmen des Waldschutzes umfassen in erster Linie chemische Bekämpfungen, ferner Kulturverfahren und, in steigendem Maße, biologische Methoden. Bei der Verwendung von Nutzorganismen wird besonders eingegangen auf den Einsatz vonTrichogramma dendrolimi gegen den Kiefernspinner (Dendrolimus-Arten), die Erprobung von zwei Schlupfwespen-Arten,Scleroderma sp. undSchreineria sp., gegen den Kleinen Pappelbock (Saperda populnea) sowie die Ansiedlung insektenfressender Vögel und die von Wieseln gegen Wühlmäuse. Ferner werden Angaben zur mikrobiologischen Bekämpfung von Schadinsekten mit insektenpathogenen Viren, Bakterien und Pilzen gemacht sowie abschließend einige Forschungsprojekte über den Einsatz von Antagonisten gegen phytopathogene Erreger vorgestellt.
    Notes: Abstract A visit to Northern China's forests on behalf of the German Agency for Technical Cooperation (GTZ) gave us the opportunity to report on some impressions. After a short description of the forestry situation overthere, a survey is given on the most important pest insects, vertebrates, and forest diseases, based on personal observations as well as on Chinese reports. Defense measures for forest protection include mainly chemical control, also silvicultural control, and recently more and more biological methods. In the report on the use of beneficial organisms, main emphasis is placed on the utilization ofTrichogramma dendrolimi to suppress the pine caterpillar (Dendrolimus spp.), the experimental use of two hymenopterous parasites,Scleroderma sp. andSchreineria sp., against the poplar borer (Saperda populnea) as well as the colonization of insectivorous birds and of weasels to suppress voles. It is also reported on the microbial control of pest insects using insect pathogenic viruses, bacteria, and fungi. Finally, some research projects on the use of antagonists against phytopathogens are mentioned.

    Description / Table of Contents: Zusammenfassung Angesichts fehlender Information über die kommerzielle Verfügbarkeit in Europa von Biopräparaten (auf der Basis von Mikroorganismen einschl. der Viren) und von nützlichen Metazoen für biologische Maßnahmen zur Unterdrückung von Schadorganismen wurde an die amtlichen Stellen, ausnahmsweise an Einzelexperten in folgenden Ländern eine Umfrage gerichtet: Frankreich, Großbritannien, Italien, Österreich, Rumänien, Jugoslawien, Schweden, die Schweiz, die Niederlande, Finnland und Bundesrepublik Deutschland. Die Ergebnisse werden in 2 Teilen als ein Momentbild des Zustandes Anfang 1984 vorgelegt. Im Begleittext wird für die Annahme einer Europäischen Zulassungsordnung für Biopräparate plädiert (die als Entwurf bereits vorliegt), um Zeit und Geld zu sparen. Zwischen den einzelnen Ländern bestehen sehr große Unterschiede bezüglich der Verfügbarkeit biotischer Agentien für biologische Verfahren. Einige vielversprechende neue Entwicklungen werden kurz in der Hoffnung vorgestellt, daß sie stimulierend wirken. Allen Kollegen, die bei der Umfrage geholfen haben, sei besonders gedankt.
    Notes: Abstract In view of the lack of information concerning the commercial availability in Europe of biopreparations (based on microorganisms including viruses) as well as of beneficial metazoa for biological control of pest organisms, an inquiry was started for the following countries: France, Great Britain, Italy, Austria, Rumania, Yugoslavia, Sweden, Switzerland, the Netherlands, Finland and Germany Fed. Rep. Results are presented as a momentary picture of the situation in early 1984. A plead is made for the acceptance of an European protocol for registration of biopreparations (which has already been drafted) in order to save money and time. There are great differences between countries in the availability of biotic agents for biological control. Some very promising new developments are briefly reviewed and considered to act in a stimulating way. Thanks are due to those colleagues who helped to obtain the information here presented.

    Description / Table of Contents: Summary The antibacterial activity of moxalactam (LY 127935) against 517 clinical isolates was assessed in comparison to cefotaxime, cefotiam, cefuroxime, cefamandole, cefoxitin, gentamicin, ampicillin and mezlocillin using the microdilution test. The in vitro activity of moxalactam was very similar to that of cefotaxime. It was almost identical againstEnterobacteriaceae; somewhat better activity was seen only againstEnterobacter spp., especially strains resistant to gentamicin and mezlocillin. Moxalactam was clearly less effective against gram-positive cocci. Beta-lactamase-positiveHaemophilus influenzae isolates were inhibited by extremely low concentrations. The activity of moxalactam againstPseudomonas aeruginosa was only moderate, although better than that of cefotaxime. The bactericidal concentrations of moxalactam were maximally two dilution steps above the MIC except in the case ofProteus andSerratia spp. Obvious effects were observed only with an inoculum of 107 organisms/ml or more.
    Notes: Zusammenfassung Die antibakterielle Aktivität von Moxalactam (LY 127935) wurde an 517 klinischen Isolaten im Vergleich zu Cefotaxim, Cefotiam, Cefuroxim, Cefamandol, Cefoxitin, Gentamicin, Ampicillin und Mezlocillin im Mikrodilutionstest bestimmt. Die Invitro-Aktivität von Moxalactam entsprach weitgehend der des Cefotaxim. BeiEnterobacteriaceae war sie nahezu identisch; etwas bessere Aktivität zeigte Moxalactam nur beiEnterobacter spp., hier vor allem bei gentamicin- und mezlocillinresistenten Stämmen. Bei grampositiven Kokken war Moxalactam deutlich schwächer wirksam. Auch β-lactamasepositiveHaemophilus-influenzae-Isolate wurden schon bei extrem niedrigen Konzentrationen erfaßt. GegenPseudomonas aeruginosa war die Aktivität von Moxalactam nur mäßig, allerdings besser als die des Cefotaxim. Außer beiProteus-undSerratia spp.-Stämmen lagen die bakteriziden Konzentrationen für Moxalactam maximal zwei Verdünnungsstufen über der MHK. Deutliche Inokulumeffekte zeigten sich erst ab einer Einsaatdichte von 107 Keimen/ml.

    Notes: Abstract Absolute cross sections for inclusive electron scattering on H, D, Be, Al, and Si have been measured in the kinematical region 0.08 (GeV/c)2〈Q 2〈1.0 (GeV/c)2 and 0.3 GeV〈v〈6.5 GeV. The measurements have been performed at incident energies of 3, 5, 6, and 7 GeV and at the fixed scattering angle of 10°. A careful treatment of radiative corrections due to elastic electron nucleus scattering, quasielastic and inelastic scattering on the bound nucleons has been applied to the measured cross sections. The comparison of the nuclear cross sections with the elementary ones leads to a value ofA eff〈A with a rapid onset of this effect at small values of the scaling variablex′.
