    Notes: Abstract  We have isolated the chicken homeobox gene NKX2.8, which represents a novel member of the NK-2 gene family. Besides the homeodomain, the NKX2.8 protein contains two other conserved sequences, a TN and an NK2 domain. NKX2.8 is expressed in the ventral foregut, the developing heart, in the epithelial layers of the branchial arches and in the dorsal mesocardium. Thus, its expression overlaps partially, but also differs significantly from another chicken tinman orthologue, the NKX2.5 gene. It is suggestive that NKX2.8 and NKX2.5 play a cooperative role in early heart development.

    Description / Table of Contents: Zusammenfassung Bei Patienten mit chronischer Uraemie konnte in Abhängigkeit von der Kreatininkonzentration im Serum eine Hemmung der intrathrombocytären Enzyme Succinatdehydrogenase und NADH-Cytochrom-C-Reduktase beobachtet werden, die noch durch Heparin gesteigert werden konnte.
    Notes: Summary In patients undergoing maintenance haemodialysis in dependence of creatinine-concentration in plasma an inhibition of the enzymes succinic dehydrogenase and NADH-cytochrom-c-reductase in platelets was observed. The inhibition of enzymes was increasing after the administrastration of heparin.

    Description / Table of Contents: Zusammenfassung Patienten mit chronischer Hämodialysebehandlung zeigten bei einem regelrechten Ascorbinsäurewert im Plasma eine herabgesetzte Konzentration der Ascorbinsäure in den Leukozyten. Daher sollte die Ascorbinsäure diesen Patienten in hoher Dosierung zugeführt werden, um einen Vitamin-C-Mangel in den Leukozyten zu verhindern.
    Notes: Summary Patients undergoing maintenance haemodialysis exhibited at a regular level of ascorbic acid in plasma a decreased concentration of ascorbic acid in leukocytes. Therefore, the ascorbic acid should be administered in a high dosage to patients undergoing chronic haemodialysis, in order to prevent a vitamin-C deficiency in leukocytes.

    Description / Table of Contents: Zusammenfassung Klinische Beobachtungen haben gezeigt, daß Co-Trimoxazol (Trimethoprim — Sulfamethoxazol) zu einem Anstieg des Serum-Kreatinins führen kann. Daher wurden bei 27 nierengesunden Probanden vor und während oraler und parenteraler Co-Trimoxazolgabe Clearanceuntersuchungen (endogene Kreatinin-und Inulinclearance) durchgeführt. Während die Inulinclearance keine signifikanten Änderungen aufwies, war die endogene Kreatininclearance nach oraler Zufuhr von Co-Trimoxazol um 18% und während parenteraler Gabe des Medikamentes um 13% herabgesetzt (p≦0,05). Diese Befunde sprechen für eine funktionelle Hemmung der tubulären Kreatininsekretion durch Co-Trimoxazol.
    Notes: Summary Clinical observations have shown, that administration of Co-trimoxazole (Trimethoprim-Sulfamethoxazole) may result in an elevation of the serum-creatinine level. In 27 subjects the endogenous creatinine- and inulinclearance were measured before and during oral or parenteral application of Co-trimoxazole. The inulinclearance showed no significant differences (p〉0,05). But the endogenous creatinine clearance showed a reduction of 18% during the oral and of 13% during the parenteral treatment (p≦0,05) These observations indicate a functional inhibition of the tubular creatinine secretion by Co-trimoxazole.

    Description / Table of Contents: Summary Coagulated Scribner shunts are very suitable for experimental studies on fibrinolysis. The proteolytic activity of Protease I, also described as Aspergillin 0 and CA 7, and derived from Aspergillus oryzae, has been studied in coagulated Scribner shunts. It has been shown that Protease I locally applied is able to dissolve arterial and venous thrombi in vivo. Compared with other fibrinolytic substances only small doses of Protease I (10–12 mg) and short periods of application (30–40 min) were necessary for shunt declottings. Determinations of the individual inhibitor levels before and after administration of Protease I showed, that the small doses of Protease I used locally in coagulated Scribner shunts did not cause change in the inhibitor levels. Therefore side effects of a systemic fibrinolytic therapy could be avoided. There were only local side effects consisting in transient pains along the cannulated vessels.
    Notes: Zusammenfassung Am Beispiel des Scribner-Shunts konnte gezeigt werden, daß es bei lokaler Applikation von Protease I (Astra), einem proteolytischen Enzym aus Aspergillus oryzae möglich ist, arterielle oder venöse Thromben in vivo aufzulösen. Relativ geringe Mengen von etwa 10–12 mg und kurze fermentative Einwirkungszeiten von 30–40 min führten dabei bereits zu eindeutigen Erfolgen, insbesondere auch bei arteriellen Thrombosen. Die Bestimmung der Inhibitorwerte vor und nach Anwendung der Protease ergab im Gegensatz zur generalisierten Zufuhr keine Veränderungen, so daß Nebenwirkungen einer allgemeinen thrombolytischen Therapie vermieden werden können. Als einzige Nebenwirkung wurden lokale Schmerzsensationen beobachtet, die nach einiger Zeit abklangen.

    Notes: Zusammenfassung Bei sechs extrakorporalen Dialysen (an vier Patienten) wurde eine isolierte Heparinisierung des extrakorporalen Kreislaufes nachGordon u. Mitarb. angewandt, wobei zwei getrennt steuerbare Infusionen von Heparin und Protaminsulfat während der Dialyse zum Einlauf kamen. Neben Dosierungsangaben für die Heparin- und Protaminsulfat-Infusionen wird über das Verhalten des Heparinblutspiegels sowie der Gesamtgerinnung im Organismus und im Dialysator berichtet. Bei einer Heparinisierung von etwa 0,75–1,0 IE Heparin pro Milliliter Blut (bei einem Umlaufminutenvolumen von 200 ml/min) und einer Protaminsulfatdosierung von etwa 10–15 γ/ml Blut liegt der Heparingehalt im Organismus mit etwa 1–2 γ/ml Blut äußerst niedrig. Daraus ergibt sich, daß die Gesamtgerinnung, gemessen mit der Recalcifizierungszeit, im Körperblut nur unwesentlich gegenüber der Norm verzögert ist. Dagegen zeigte die Recalcifizierungszeit mit Werten von etwa 300 sec eine ausreichende Gerinnungshemmung im Dialysatorblut. Es konnte somit gezeigt werden, daß es mit dieser Methode gelingt, den Heparinblutspiegel im Organismus während extrakorporaler Dialyse äußerst niedrig zu halten, so daß eine schwere Blutungsbereitschaft keine absolute Kontraindikation zur Durchführung einer extrakorporalen Dialyse darstellt.

    Description / Table of Contents: Summary In 38 extracorporeal dialyses of oligo-anuric patients the heparin elimination was tested by quantitative determination of the heparin contents in the patient's blood. The elimination of heparin follows in the first few hours an e-function, whereby 60% of the added heparin will be eliminated within the first 3 hours. In 7 normal persons, who for control, were tested with about the same single dose of heparin, the same decrease in the concentration of heparin in the blood was observed, as in patients with renal insufficiency and oligoanuria during extracorporeal dialysis.
    Notes: Zusammenfassung Bei 38 extrakorporalen Dialysen oligoanurischer Patienten wurde die Heparinelimination mittels quantitativer Bestimmung des Heparingehaltes im Patientenblut geprüft. Die Heparinelimination folgt innerhalb der ersten Dialysestunden einer e-Funktion, wobei 60% des zugeführten Heparins in den ersten 3 Std eliminiert werden. Bei 7 Normalpersonen, die zur Kontrolle mit etwa der gleichen einmaligen Heparindosis belastet wurden, ergab sich derselbe Heparinkonzentrationsabfall im Blut wie bei niereninsuffizienten, oligo-anurischen Patienten während extrakorporaler Dialyse.

    Notes: Summary Following swarming ofVibrio alginolyticus on solid medium a large number of giant flagellar bundles appear behind the growth front. The suggested sequence of events leading to bundle formation is as follows. After inoculation from liquid to solid media the short rods with a single polar sheathed flagellum develop peritrichous nonsheathed flagella and elongate into long filamentous swarmers. After division into short rods, some of the cells become spherical in shape with many peritrichous flagella concentrated at one pole in close association with the sheathed polar flagellum. These tufted spherical bodies form the “template” upon which masses of loose peritrichous flagella spontaneously aggregate. Flagellar bundles formed when bacteria are grown at pH 8.5 are longer than those formed at pH 7.2 and shorter when grown at pH 6.5. In distilled water the flagellar bundles disintegrate into masses of flagellar fragments.
