Abstract
Hintergrund Seit 2015 erfolgt in Europa mithilfe des EUROCRINE®-Registers eine systematische Dokumentation endokrin-chirurgischer Operationen. Ziel dieser ersten Auswertung war eine Darstellung der Versorgungsrealität für Nebenniereneingriffe in einem homogenen Versorgungsumfeld, entsprechend des deutschsprachigen Raums – bzw. des Präsenzgebiets der Chirurgischen Arbeitsgemeinschaft Endokrinologie (CAEK) der Deutschen Gesellschaft für Allgemein- und Viszeralchirurgie (DGAV) – einschließlich einer Analyse der Adhärenz zu geltenden Therapieempfehlungen. Methodik Es erfolgte eine deskriptive Analyse der präoperativen Diagnostik, der angewandten Operationstechniken sowie der zugrunde liegenden histologischen Entitäten der zwischen den Jahren 2015 und 2019 über EUROCRINE® in Deutschland, Österreich und der Schweiz dokumentierten Nebennierenoperationen. Ergebnisse In den insgesamt 21 teilnehmenden Kliniken des deutschsprachigen EUROCRINE®-Gebiets wurden 658 Operationen an Nebennieren durchgeführt. In 90 % erfolgten unilaterale, in 3 % bilaterale Adrenalektomien und in 7 % andere Resektionsverfahren. Die in 41 % der Operationen dokumentierte histologische Hauptdiagnose war das adrenokortikale Adenom. In 15 % lagen maligne Befunde zugrunde (einschließlich 6 % Nebennierenrindenkarzinome (ACC) und 8 % Nebennierenmetastasen). 23 % der Operationen erfolgten bei Phäochromozytomen. Diese wurden zu 82 % minimal-invasiv operiert, Nebennierenrindenkarzinome lediglich zu 28 % und Nebennierenmetastasen zu 66 %. Schlussfolgerung Überraschenderweise wurden nach Nebennierenadenomen und Phäochromozytomen an dritthäufigster Stelle Nebennierenmetastasen unterschiedlicher Primärtumoren reseziert. 28 % der ACC waren für minimal-invasive Techniken vorgesehen, wobei 20 % dieser Fälle eine Konversion zur offenen Operation erforderten. Die aktuelle Analyse deckte Diskrepanzen zwischen Versorgungsrealität und Leitlinienempfehlungen auf, aus denen sich zahlreiche Fragestellungen ergeben, welche nun in ein überarbeitetes EUROCRINE®-Modul zur Dokumentation von Nebennierenoperationen einfließen werden.

Abstract
Bulky and hyphenated laboratory-based analytical instrumentation such as gas chromatography/mass spectrometry is still required to trace breath biomarkers in the low ppbV level. Innovative sensor-based technologies could provide on-site and point-of-care (POC) detection of volatile biomarkers such as breath aldehydes related to oxidative stress and cancer. An electrochemical sensor system was developed for direct detection of the total abundance of aldehydes in exhaled breath in the ppbV level and for simultaneous determination of the airway inflammation markers carbon monoxide (CO) and nitric oxide (NO). The sensor system was tested in vitro with gaseous standard mixtures and in vivo in spontaneously breathing patients and under mechanical ventilation in an animal model. The sensor system provided in vitro and in vivo detection of trace levels of aldehydes, CO and NO. Inertness of the tubing system was important for reliable results. Sensitivity of the aldehyde sensor increased with humidity. Response time for analysis of breath samples was about 22 s and relative standard deviations of sensor amplitudes were <5%. Detection limits in the low ppbV range and a linear range of more than two orders of magnitude could be achieved for volatile aldehydes. Cross sensitivities were moderate for alcohols such as ethanol or isopropanol and negligible for other typical breath volatile organic compounds such as acetone, isoprene or propofol. In proof of concept analyses in patients suffering from lung cancer and diabetes, aldehyde and CO sensor signals differed between the groups. Elevated CO levels indicated previous smoking. In a mechanically ventilated pig, continuous monitoring of breath aldehyde concentrations in the low ppbV was realized. Cumulative aldehyde measurements may add interesting and complementary information to the conventional parameters used in clinical breath research. POC applicability, easy handling and low cost of sensors facilitate measurements in large patient cohorts.

Abstract
It was the aim of this study to investigate the antileukemic activities of recombinant interferon beta (rIFN beta) in chronic-phase CML in vitro and in vivo. Nine patients in the early chronic-phase of CML were treated in a phase-II trial with escalating doses of rIFN beta. In parallel, antiproliferative and immunomodulatory activities of rIFN beta and rIFN alpha 2b were studied in vitro. rIFN beta exhibited a significantly higher antiproliferative activity on hematopoietic progenitor cells of CML patients in vitro than rIFN alpha 2b. In contrast, only very limited clinical antileukemic efficacy of rIFN beta was observed. None of the patients achieved a complete or partial hematologic response (0% response rate, 0-36% 95 C.I.). Primary resistance of CML patients to rIFN beta treatment was caused neither by antibody formation against the recombinant material nor by deficient IFN receptor targeting and/or signaling; Induction of serum levels of beta-2-microglobulin (beta-2-m) and neopterin after administration of rIFN beta was comparable to that seen after administration of rIFN alpha. However, rIFN beta treatment less effectively induced biosynthesis of interleukin-1 receptor antagonist protein (IL-1-Ra) than rIFN alpha 2b. Thus, we conclude that rIFN beta at doses up to 12 MU/day s.c. is ineffective for treatment of chronic-phase CML. Further investigations into divergent biologic responses to various type-I interferons might help to elucidate mechanisms crucial for IFN action in patients with CML.

Abstract
Preclinical in vitro assessment of highly purified natural human interleukin-2 (IL-2) packed in egg lecithin liposomes was performed in short- and long-term T-cell cloning and propagation systems, and in experiments testing induction of lymphokine-activated killer (LAK) cells. Liposomal IL-2 (lip-IL-2) was essentially as active as free natural or recombinant IL-2 for cloning and culture of both helper and cytotoxic alloreactive T cells. However, lip-IL-2 was found to be markedly inferior to free natural or recombinant IL-2 for the induction of LAK cells from normal donors. Nevertheless, lip-IL-2 was able to maintain LAK cytotoxicity of populations preactivated with free IL-2. These results suggest that lip-IL-2 can interact with activated T cells and LAK cells in the same way as free IL-2, but that it is much less efficient at activating LAK-cell precursors.

Abstract
Praziquantel, a new anthelmintic drug with activity against all species of schistosomes pathogenic to man, and against a wide range of Cestodes, was tested for mutagenic potential. For the detection of both base substitutions and frameshift mutations, Salmonella typhimurium TA 100 and TA 98 were used as tester strains. Using the plate assay with and without added S-9, host-mediated assay and urine-mediated assay without and after incubation with beta-glucuronidase/arylsulfatase, no mutagenic activity could be detected.

Abstract
THE ACTIVITIES OF THE FOLLOWING ENZYMES HAVE BEEN DETERMINED IN NUCLEI OF QUAIL OVIDUCTS IN RESPONSE TO EXOGENOUS STIMULATION OF THE BIRDS WITH DIETHYLSTILBESTROL, USED AS AN ESTROGEN ANALOGUE AND PROGESTERONE: DNA dependent DNA polymerase, DNA dependent RNA polymerase I and II and poly(adenosine diphosphate-ribose) [=poly(ADP-Rib)] polymerase.During primary stimulation with the estrogen analogue the activities of the four DNA dependent polymerases increase to about the same degree. Upon withdrawal of the hormones the levels of the enzymes drop to values known from nuclei from unstimulated quail oviducts. The secondary stimulation with the estrogen analogue causes a significant increase only of the RNA polymerase II. The in vivo induction of avidin by progesterone in oviduct mucosa cells from quails, during the period of primary estrogen stimulation, is accompanied by an increase of RNA polymerase II activity and a marked decrease of poly(ADP-Rib) polymerase activity. The activities of RNA polymerase I and of poly(ADP-Rib) polymerase are not affected significantly by an exogenous administration of progesterone.
