    Description / Table of Contents: Zusammenfassung Die Wirkung von Acyclovir intravenös (in einer Dosis von 30 mg/kg pro Tag für fünf Tage) auf den unkomplizierten Herpes zoster wurde bei 51 Patienten in einer Doppelblindstudie geprüft. Obwohl bei den vorhandenen Herpes zoster-Läsionen eine Tendenz zu rascherer Heilung bestand und das Neuauftreten von Läsionen in der Acyclovir-Gruppe etwas früher aufhörte, waren diese Unterschiede statistisch nicht signifikant. Unter der Behandlung war die Schmerz-Score bei Patienten, die Acyclovir erhielten, signifikant niedriger als bei Patienten, die Placebo erhielten. Bei der Verlaufsbeurteilung fanden sich zwischen den Gruppen jedoch keine Unterschiede. Zu Komplikationen des Herpes zoster kam es nur in der Plazebo-Gruppe (in je zwei Fällen Generalisation und Keratitis). Mit der möglichen Ausnahme des Zoster im Trigeminus-Bereich oder starker Schmerzen scheint Acyclovir bei immunkompetenten Patienten mit Herpes zoster nur von geringem Wert zu sein.
    Notes: Summary The effect of intravenous acyclovir (at a dosage of 30 mg/kg per day for five days) on uncomplicated herpes zoster was investigated in 51 patients in a double-blind study. Although existing herpes zoster lesions tended to heal more rapidly and new lesions ceased to appear somewhat earlier in the acyclovir group, these differences were not statistically significant. During treatment, patients on acyclovir had significantly lower pain scores than placebo-treated patients. At follow-up, however, there was no difference between the two groups. Complications of herpes zoster occurred only in the placebo groups (generalization in two and keratitis in two cases). With the possible exception of trigeminal zoster or severe pain, acyclovir seems to offer little benefit for immunocompetent patients with herpes zoster.

    Description / Table of Contents: Zusammenfassung Wir berichten über einen Patienten mit Hirnabszeß, der durchStreptobacillus moniliformis (den Erreger der Streptobazillen-Rattenbißkrankheit) und durchActinobacterium meyerii verursacht wurde. Hirnabszesse durch diese Erreger sind selten. Die vermutliche Pathogenese bei diesem Patienten sowie die diagnostischen und therapeutischen Möglichkeiten bei Hirnabszessen im allgemeinen werden besprochen.
    Notes: Summary This paper deals with a case of brain abscess due toStreptobacillus moniliformis (the cause of the streptobacillary type of rat-bite fever) andActinobacterium meyerii. Brain abscesses due to these micro-organisms are rare. The possible causative mechanisms in this particular case and the diagnostic and therapeutic management of brain abscesses in general are discussed.

    Description / Table of Contents: Zusammenfassung Der Einfluß der Granulozyten, Monozyten und Lymphozyten auf den Verlauf einer Infektion unter Antibiotikabehandlung wurde quantitativ bestimmt. Als Tiermodell wurde eine Kurzzeitinfektion der Oberschenkelmuskulatur bei normalen oder bestrahlten Mäusen gewählt. Zwei Arten von Antibiotika wurden verwendet: Tobramycin fürPseudomonas aeruginosa- und Ampicillin fürEscherichia coli-Infektionen. Die Granulozytenzahl wurde durch Bestrahlung der Mäuse vor Setzen der Infektion verändert. Die Dosis-Wirkbeziehungen für beide Kombinationen von Bakterien und Antibiotika wurden an verschiedenen Tagen nach Bestrahlung bestimmt. Die Analyse der Ergebnisse zeigte, daß der Antibiotikaeffekt vorwiegend durch die Granulozyten potenziert wurde. Das bedeutet, daß unter den Bedingungen der Granulozytopenie die Dosis eines Antibiotikums erhöht werden muß, um einen entsprechenden antibakteriellen Effekt zu erzielen. Die vorgelegten Ergebnisse zeigen, daß es möglich ist, die Wechselbeziehung zwischen Wirtsfaktoren, Bakterienwachstum und Antibiotikatherapie quantitativ zu erfassen; daraus läßt sich möglicherweise ein brauchbares Modell für das Screening von antimikrobiellen Substanzen vor ihrer Anwendung in der Klinik ableiten.
    Notes: Summary We are presenting a quantitative determination of the effect of granulocytes, monocytes and lymphocytes on the course of infection during antibiotic treatment. The animal model was a short-term infection of the thigh muscle in normal or irradiated mice. Two kinds of antibiotics were used: tobramycin forPseudomonas aeruginosa infections and ampicillin forEscherichia coli infections. The number of granulocytes was changed by irradiating the mice before they were infected. The dose-effect relations for both combinations of bacteria and antibiotics were determined on various days after irradiation. Analysis of the results shows that the effect of an antibiotic was predominantly potentiated by granulocytes. This means that under the conditions of granulopenia, the dose of an antibiotic must be increased to obtain the same antibacterial effect. The present results indicate that the interrelation between host factors, bacterial proliferation and antibiotic treatment can be quantitated and may offer a useful model for screening antimicrobial drugs before they are clinically applied.

    Description / Table of Contents: Samenvatting Bij gezonde vrijwilligers werd de resorptie van amoxicilline bepaald na orale toediening van verschillende capsules en suspensies van twee handelspreparaten. De resorptie uit suspensie is sneller en vollediger dan uit capsules. Tussen vrijwilligers bestaat een grote variatie in resorptie.
    Notes: Abstract Absorption of amoxicillin was measured in healthy volunteers after oral administration of various capsules and suspensions of two brands. Absorption from suspension is faster and more complete than from capsules. There is a large variation in absorption between volunteers.

    Notes: Abstract A method is described to express the effect of antimicrobial drugs on the growthin vitro of variousBacteroides species during the first few hours of exposure. Drugs studied were clindamycin, chloramphenicol, metronidazole, and tinidazole. The effect of the various drugs is expressed at different time points as the log ratio, this being the logarithm of the ratio of the number of colony forming units in the control growth and that in the presence of the drug. For any given concentration, the course of the log ratio in time can be fitted to the equation $$\log ratio = i\left( {t + e^{ - t} - 1} \right),$$ wherei is a concentration-dependent parameter. Concentration-effect curves on the basis of values ofi show a different behavior of drugs with different modes of action. Those curves also show that the interpretation of the minimal inhibitory concentration after 24 h is different for different kinds of drugs.
