    Description / Table of Contents: Summary Leukocytes from donor blood were separated by Ficoll/Urovison density centrifugation into granulocytes, lymphocytes and monocytes. The cell fractions were suspended in a culture medium to which endotoxin of Salmonella enteritidis was added at a final concentration of 10 µg/ml. Endotoxin-stimulated monocytes developed a very high tissue factor (thromboplastin) activity while in granulocytes an only negligible amount of tissue factor activity was detectable. The tissue factor activity measured in the preparation of the lymphocytes can be explained by contamination with monocytes. Electron microscopic studies showed the lysosomes of all monocytes to be enlarged and activated. Only a fraction of the granulocytes appeared degranulated with prominent vacuoles containing inclusion bodies. Possibly the high tissue factor activity of the monocytes triggers the development of the disseminated intravascular coagulation in the Shwartzman phenomenon.
    Notes: Zusammenfassung Leukozyten aus Spenderblut wurden durch Dichtegradientenzentrifugation über Ficoll/Urovison in Granulozyten, Lymphozyten und Monozyten aufgetrennt. Den in einem Kulturmedium suspendierten Zellen wurde 10 µg/ml Endotoxin von Salmonella enteritidis über mehrere Stunden zugesetzt. Die Stimulierung mit Endotoxin führte bei den Monozyten zu einer sehr hohen Gewebsthromboplastinfreisetzung, während aus Granulozyten so gut wie kein Thromboplastin freigesetzt wurde. Die in Lymphozyten gemessene Aktivität ist auf eine Monozytenverunreinigung zurückzuführen. Elektronenmikroskopisch wiesen alle Endotoxin- stimulierten Monozyten große, aktivierte Lysosomen auf, während nur bei einem Teil der Granulozyten eine Degranulierung und Vakuolisierung mit Einschlußkörpern zur Beobachtung kam. Die hohe Gewebsthromboplastinfreisetzung Endotoxin-stimulierter Monozyten vermittelt möglicherweise die Auslösung der disseminierten intravasalen Gerinnung beim Shwartzman-Sanarelli Syndrom.

    Notes: Summary The dose-response relationship in the intravenous immunoglobulin treatment of idiopathic thrombocytopenic purpura was studied in 20 adult patients in a multicenter prospective crossover trial. The rate of response increases from 3 out of 11 (27%) to 6 out of 10 treatment periods (60%) by raising the 7S-IgG dose given on 5 consecutive days from 164.50±24.55 to 359.65±58.62 mg/kg body weight. The onset and duration of response as well as the peak platelet count were found to be independent of the doses. A long-term benefit induced by intravenous immunoglobulin treatment could be achieved in 2 out of 14 patients with chronic idiopathic thrombocytopenic purpura.

    Notes: Summary The present intensification of cancer chemotherapy has resulted in increased toxicity. Nausea and vomiting are often severe and prolonged, rendering a patient unfit for further treatment. This review summarizes the current understanding of the physiology of vomiting and the pharmacology and efficacy of the antiemetics in clinical use. It also discusses new approaches with agents, such as cannobinoids, high-dosage metoclopramide, and high-dosage corticosteroids. The new agents are superior to standard antiemetic drugs as demonstrated in a number of trials.

    Description / Table of Contents: Zusammenfassung Aus 25 Operationspräparaten von 19 Patienten wurden wäßrige Schilddrüsenextrakte hergestellt. Die Thromboplastinzeiten der 3:4 verdünnten Struma-Rohextrakte betrugen bei euthyreoten Patienten 16,8±2,3 sec mit 100%-Humanplasma. Für Rohextrakte aus der grauen Substanz von drei menschlichen Gehirnen wurde unter vergleichbaren Bedingungen eine mittlere Thromboplastinzeit von 18,4±0,3 sec ermittelt. Die Schilddrüse zählt somit zu den thromboplastinreichsten Organen.
    Notes: Summary Aqueous extracts of thyroid glands were prepared from 25 surgical specimens of 19 patients. The average prothrombin time of sixteen 3:4 diluted extracts of thyroids from 13 euthyroid patients was 16.8±2.3 sec as measured with 100% human plasma. Under similar conditions the average prothrombin time of extracts obtained from the grey matter of three human brains was 18.4±0.3 sec. The thyroid may thus be considered as an organ containing one of the highest concentrations of tissue thromboplastin.

    Description / Table of Contents: Zusammenfassung Bei einer 68-jährigen Patientin mit portal dekompensierter Leberzirrhose wurde versucht, den intraktablen Aszites mit einem peritonealjugularen Shunt zu behandeln. Im Verlauf der 14 tägigen kontinuierlichen Reinfusion von Aszites kam es zu einer Verbrauchskoagulopathie, die schließlich die Unterbindung des Shunts veranlasste. Nach Unterbrechen des Shunts konnte dann eine weitgehende Besserung des Fibrinogenspiegels und der Thrombozytenzahlen beobachtet werden. Die Sektion ergab neben der schon bekannten Zirrhose eine Endophlebitis hepatica obliterans. Zur Klärung eines ursächlichen Zusammenhangs zwischen Auftreten einer DIC und kontinuierlicher Aszites-Reinfusion wurde Aszitesflüssigkeit mehrerer Patienten hämostaseologisch untersucht. Dabei fanden sich sehr unterschiedliche Spiegel an Prokoagulationsfaktoren und Gerinnungsinhibitoren. Bei einem Teil der untersuchten Fälle war ein Überwiegen der Prokoagulationsfaktoren festzustellen. Darüber hinaus konnte im Aszites der Patientin eine Kontaktfaktor-Aktivierung nach Shunt-Implantation wahrscheinlich gemacht werden. Unter Zugrundelegung der aus diesen orientierenden Untersuchungen gewonnenen Erkenntnisse erscheint es künftig unerläßlich, bei Patienten, bei denen eine Implantation eines Le Veen-Shunts erwogen wird, hämostaseologische in-vitro-Untersuchungen der Aszitesflüssigkeit vorzunehmen und vor dem geplanten Eingriff eine probatorische Reinfusion einer größeren Menge Aszites mit gleichzeitiger Verlaufskontrolle der wichtigsten Hämostaseparameter durchzuführen. Diese Untersuchungen könnten möglicherweise dazu beitragen, durch rechtzeitige Erkennung solcher Risikofaktoren bei der Auswahl der mit dieser Methode zu behandelnden Patienten eine Selektion vorzunehmen und damit im Einzelfall die Gefahr der Entstehung einer DIC nach Anlegen eines Le Veen-Shunts zu vermindern.
    Notes: Summary In a 68-year-old woman with cirrhosis of the liver an attempt was made to treat the intractable ascites by a peritoneal-jugular shunt. In the course of the two-week continuous reinfusion of ascites a disseminated intravascular coagulation (DIC) developed which made a ligation of the shunt necessary. After ligation the fibrinogen and platelets rose to normal levels. To evaluate the relationship of the DIC to the continuous reinfusion of ascites, a coagulation profile of the ascitic fluid of a number of patients was performed. It could be demonstrated that the procoagulant activities and factors inhibiting coagulation varied widely although, in some cases, procoagulant factors predominated. Furthermore, in the ascitic fluid of the one patient described in detail activation of the contact factor could be shown following implantation of the shunt. The results of these investigations suggest that in future candidates for a Le Veen shunt, in vitro clotting tests should be performed of the ascitic fluid and a probatory reinfusion of a large amount of ascitic fluid with a parallel evaluation of the most important clotting parameters. A patient at risk to develop DIC following the insertion of a Le Veen shunt perhaps could thus be recognized prior to such a procedure.

    Notes: Summary Twenty patients with cancer previously unresponsive to antiemetic treatment of chemotherapy-induced nausea and vomiting were treated with the new tetrahydrocannabinoid Levonantradol. 15 patients experienced substantial relief and 10 of them preferred the drug for further courses. These observations suggest that Levonantradol can be beneficial to patients refractory to conventional antiemetic therapy.

    Notes: The lifetime T1 of the symmetric Si–H stretching mode for the Si(100)/H:2×1 surface is significantly longer (T1(approximately-greater-than)6 ns at 100 K) than for Si(111)/H:1×1. T1 is strongly sample dependent and temperature dependent. Samples with the longest lifetimes also show the smallest inhomogeneous width. The difficulty in reproducing the longer lifetimes at low temperature indicates that the measured T1 may not be intrinsic and may by due to defects. The deuterated surface has a lifetime of 250±30 ps with little variation from sample to sample and a weak temperature dependence. It is expected to be the intrinsic lifetime. On the hydrogenated surface, the energy transfer time between the symmetric and asymmetric mode is measured to be 90±15 ps at 100 K. From photon-echo measurement, the measured dephasing time at 100 K is 75±5 ps. We propose that the dephasing on that surface is induced by a low-energy silicon phonon (200–300 cm−1) as for the Si(111)/H:1×1 surface. We derive an expression relating the dephasing time and the energy transfer time for the general case of two coupled oscillators and discuss its application to this system. © 1995 American Institute of Physics.
