    Description / Table of Contents: Zusammenfassung Humoralen Faktoren kommt wahrscheinlich eine wesentliche Bedeutung bei der Aufrechterhaltung des Proliferationsgleichgewichtes in der Blutbildung zu. Am besten untersucht sind Stimulatoren und Inhibitoren der Granulopoese. Unter ihnen ist der Kolonie-stimulierende Faktor chemisch und biologisch am weitesten charakterisiert. Untersuchungen über zellinienspezifische Stimulatoren und Inhibitoren der Lymphopoese gewinnen ebenfalls zunehmendes Interesse. Verschiedene Gewebeextrakte und Überstände von Zellinien wurden teilweise gereinigt und charakterisiert. Monozyten scheint als Produzenten von Stimulatoren und Inhibitoren eine zentrale Funktion bei der Regulation der Zellproliferation in der Hämatopoese zuzukommen. Die in vitro gewonnenen Ergebnisse machen viele bisher nicht erklärbare Beobachtungen bei Patienten mit gestörter Hämatopoese verständlicher. Ihre tatsächliche Bedeutung in vivo muß jedoch noch offen bleiben.
    Notes: Summary Humoral Factors obviously play an important role in the maintenance of the steady state in haematopoiesis. There has been work on stimulators and inhibitors for several years. Colony-stimulating factor is the best characterized chemically and biologically. Interest in more or less cell-line-specific stimulators and inhibitors of lymphopoiesis is now growing. Various tissue extracts and cell culture supernatants have been partially purified and characterized biologically and chemically. Monocytes, producing stimulators and inhibitors, have a central function in the regulation of cell proliferation in haematopoiesis. Experiments performed in vitro can help better to understand data so far difficult to explain regarding patients with disturbed haematopoiesis. The in vivo relevance of these experiments, however, remains unclear.

    Notes: Summary A 54-year-old man was admitted to hospital with acute rhabdomyolysis and myoglobinuria due to hypokalemia. The hypokalemia was due to chronic licorice ingestion and diuretic treatment. The myoglobinemia led to a glomerulopathy and tubulopathy. There was, however, no clinical evidence of acute renal failure (ARF). We propose that the volume expansion caused by the steroid-like actions of licorice might have prevented the development of an ARF.

    Description / Table of Contents: Zusammenfassung Wäßrige Extrakte aus Kalbsmilz wurden durch Azetonfällung, Membranfiltration, Affinitätschromatographie und Dialyse gereinigt. Diese Extrakte hemmten den Thymidineinbau in lymphoiden Zellen (MKT-CH und PHA-stimulierte Lymphocytenkulturen). Zellen nicht lymphatischen Gewebes (Melanomzellen Mel Ei 78 und Ehrlich-Ascites-Zellen) wurden nicht beeinflußt. Die Hemmung war reversibel, und die Reinextrakte wirkten nicht zytotoxisch. Die Extrakte entsprechen einem Chalon. Ihre mögliche Bedeutung für die Verhinderung der Graft versus host reaction und für die Behandlung lymphoproliferativer Erkrankungen wird diskutiert.
    Notes: Summary Aqueous spleen extracts were purified using acetone precipitation, membrane filtration, affinity chromatography, and dialysis. These extracts were able to inhibit thymidine incorporation into lymphoid cells (MKT-CH and PHA-stimulated lymphocyte cultures). They did not influence non lymphoid tissues (melanoma cells Mel Ei 78 and Ehrlich ascites cells). The inhibition was reversible and the purified extracts were not cytotoxic. The extracts correspond to a chalone. Their importance for prevention of graft versus host reaction and for treatment of lymphoproliferative diseases is discussed.

    Description / Table of Contents: Zusammenfassung Bei der Aufrechterhaltung des Proliferationsgleichgewichtes in der Blutbildung spielen humorale Faktoren wahrscheinlich eine wesentliche Rolle. Neben Erythropoetin wurden weitere Stimulatoren der Erythropoese im Serum gefunden. Inhibitoren der Erythropoese wurden in Erythrocytenüberständen, in Neugeborenen-Urin und in Plasma von Patienten mit Niereninsuffizienz nachgewiesen. Stimulierende Faktoren der Megakaryopoese finden sich in konditionierten Medien von lymphoiden Zellen und Knochenmarkzellen, inhibierende Faktoren konnten in verschiedenen Seren nachgewiesen werden. Auch die Proliferation der pluripotenten Stammzelle unterliegt wahrscheinlich einem humoralen Regulationsmechanismus. Stimulatoren und Inhibitoren wurden in Knochenmarkextrakten gefunden. Die klinische Bedeutung dieser Faktoren wird diskutiert.
    Notes: Summary Diffusible factors probably play an important role in the control of cell proliferation during haematopoiesis. Several stimulators of erythropoiesis including erythropoietin are to be found in sera. Inhibitors are found in erythrocyte supernatants, in the urin of newborn children, and in plasma of patients with renal insufficiency. Stimulators of megakaryopoiesis have been shown to be present in conditioned media of lymphoid cells and bone marrow cells. Inhibitors have been detected in various sera. Proliferation of multipotent stem cells is probably also regulated by a humoral mechanism. Stimulators and inhibitors are present in bone marrow extracts. Clinical relevance of these factors is discussed.

    Description / Table of Contents: Zusammenfassung Bei 120 chronischen Alkoholikern wurden in einer prospektiven Studie von Juli 1978 bis Januar 1980 am Aufnahmetag folgende Veränderungen des Blutes und blutbildenden Systems beobachtet: Erhöhung des mittleren Erythrozytenvolumens (MCV) (64%) und des MCH (32%), Thrombozytopenie (48%), Erhöhung des Sideroblastenanteiles im Knochenmark (35%), Erniedrigung der Sideroblasten (37%), megaloblastäre Veränderungen (55%) mit Kernanomalien (32%), sowie Plasmavakuolen in den Vorläuferzellen der Erythropoiese (20%) und Granulopoiese (16%). Diese Veränderungen traten unabhängig vom Vorliegen einer Leberzirrhose mit Hypersplenie-Syndrom auf (MCV in 52% ohne Leberzirrhose und in 76% mit Leberzirrhose ohne Blutung erhöht). Bei Alkoholkarenz stiegen die Thrombozytenzahlen innerhalb von 6 Tagen wieder an. Das Serumeisen war in 32% erniedrigt und in 42% erhöht, die totale Eisenbindungskapazität in 54% und das Ferritin in 41% vermehrt und das Transferrin in 20% vermindert. Im Gegensatz zu den Angaben im angelsächsichen Schrifttum lag die Folsäure im Serum bei der Mehrzahl unserer Patienten im Normbereich (87%), wahrscheinlich wegen unterschiedlicher Trink- und Eßgewohnheiten. Der Sideroblastenanteil im Knochenmark war ebenfalls im Mittel niedriger. Die Reifungsstörungen sind wahrscheinlich z.T. Folge eines toxischen Einflusses von Alkohol auf den Nukleinsäurestoffwechsel der Knochenmarkzellen.
    Notes: Summary In a prospective trial with 120 chronic alcoholics (July, 1978 to January, 1980) on admission the following haematological values significantly different from those of the normal population were found: elevated erythrocyte mean corpuscular volume (64%), increased mean corpuscular hemoglobin (32%), thrombocytopenia (48%), increased percentage of bone marrow sideroblasts (35%), decreased percentage of sideroblasts (37%), megaloblastic bone marrow changes (55%) including nuclear abnormalities (32%), and vacuolization in red cell (20%) and white cell (16%) precursors. These changes were independent of liver cirrhosis with hypersplenism (increased mean corpuscular volume in 52% of the patients who did not have liver cirrhosis, increased mean corpuscular volume in 76% of the patients who were cirrhotic but not suffering from major bleeding). Platelets returned to normal values within 6 days of discontinuation of alcohol ingestion. In respect to iron metabolism we found the following changes: decreased serum iron concentration (32%), increased iron concentration (42%), increased total iron binding capacity (54%), increased ferritin (41%), decreased transferrin (20%). In contrast to data from the Anglo-American literature, serum folate concentrations were mostly normal in our patients (87%). This may be due to different eating and drinking habits. The percentage of bone marrow sideroblasts was also lower in our patients than those described in the literature mentioned above. The changes in maturation are likely to be caused partially by a toxic effect of alcohol on nuclear metabolism of bone marrow cells.

    Description / Table of Contents: Zusammenfassung Die zytotoxische Aktivität der natürlichen Killerzellen (NK) wurde bei gesunden Spendern und Patienten mit Plasmocytom unter dem Einfluß von humanem Fibroblasteninterferon (IFN-β) in vitro und in vivo gemessen. IFN-β steigerte die NK-Aktivität gegenüber allen getesteten Zielzellen in vitro dosisabhängig bis zu 250% des Ausgangswertes. Bei weiterer Erhöhung der IFN-Konzentration nahm die Stimulation wieder ab. Die Stimulation war bei niedriger Lymphozyten-Zielzell-Relation am deutlichsten zu sehen. Eine 1- bis 2stündige Präinkubation der Effektorzellen mit Interferon reichte aus, um die maximale Stimulation zu erreichen. Wurde der Einfluß von IFN-β auf NK-Zellen in vivo im Blut von Interferon-behandelten Patienten mit Plasmocytom gemessen, zeigte sich eine deutliche Verminderung der Toxizität gegenüber allen getesteten Zielzellen während der ersten Infusion im Vergleich mit dem Ausgangswert vor Interferon-Therapie.
    Notes: Summary This paper describes the influence of human fibroblast interferon (IFN-β) on the cytotoxic activity of natural killer cells (NK) in vitro and in vivo using the blood of healthy donors and myeloma patients. IFN-β stimulates NK activity against all target cells tested in vitro in a dose-dependent way up to 250% of pretreatment values. At higher IFN concentrations, stimulation returned to baseline values. Stimulation was most pronounced in the lowest lymphocyte to target cell ratio. 1- to 2-h preincubation of effector cells with IFN was enough to achieve maximal stimulation. The effector cells of IFN-treated myeloma-patients, or patients with herpes zoster, showed a clear reduction of toxicity against all cells tested during the first infusion, as compared to the pretreatment values.

    Notes: Summary Even though the enhancement of the lyitc capacity and the kinetics of lysis of natural killer cells (NK) by interferon has been well documented, an increase of the target-effector cell binding percentage is still disputed. We, therefore, modified the Grimm-Bonavida single-cell assay so that 400 to 600 cells per individual determination could be reliably evaluated. Using this assay, which makes possible separate determination of effector-target cell binding and target lysis, we demonstrated that, in addition to lytic capacity, target-effector cell binding is also increased by preincubating NK with 100 to 1,000 IU interferon alpha 2 per 106 cells. Our data indicate that interferon alpha 2 induces pre-NK cells to bind target cells and that it activates these pre-NK cells to kill the targets.
