    Notes: Summary Low molecular weight (LMW) heparin Kabi 2165 possesses improved pharmacodynamic properties compared with conventional heparin. It is currently investigated in the prophylaxis of thromboembolism. The neutralization of Kabi 2165 by protamine chloride was analysed after i.v. injection of both the agent and the antidot in healthy persons. The anticoagulant effects of the LMW heparin on the activated partial thromboplastin time, thrombin, and thromboelastography are completely and immediately suppressed by protamine chloride. The inhibition of factor X a is antagonized up to 50%–60%. The bleeding time remained unaffected. The data indicate that protamine chloride may be used in clinical situations as an antidot to the LMW heparin Kabi 2165. A rebound phenomenon of the anticoagulant effect does not occur.

    Notes: Summary Patients with severe bleeding complications and other side effects on conventional anticoagulants and strong indication for further anticoagulation were treated with a low molecular weight heparin fragment (Tedelparin). In this paper we report the experiences in 30 patients, who were anticoagulated 1–11 months with this compound. All patients injected themselves a dose ranging from 1 × 2,500 to 1 × 20,000 anti factor Xa units per day. Within 132 months of treatment one patient with good compliance developed thromboembolism. Four patients had bad compliance. Two of them experienced rethrombosis 1 and 8 weeks after starting therapy. Severe haemorrhages did not occur. Two patients had one minor bleeding complication each. Both patients developed several times per year severe haemorrhages with conventional anticoagulants. All excessive subcutaneous haematomas and indurations of the adipose tissue at the injection site of conventional heparin disappeared completely. Low molecular weight heparin can be regarded as an alternative anticoagulant in patients with severe bleeding and other complications on oral anticoagulants and conventional heparin.

    Notes: Abstract Nonlinear absorption and refractive index changes in wide-gap semiconductors (CdS, CdSSe, and GaSe) after ps light irradiation are determined with an excite-and-probebeam spectrometer. Based on a simple model pump-pulse induced chirp parameters on a signal pulse of different wavelength are calculated. Possible applications are discussed.

    Notes: Summary Second trimester abortion was induced by the intraamniotic infusion of ethacridine. Coagulation studies revealed no change in 10 cases. It is felt that the intraamniotic use of ethacridine is probably safe.

    Notes: Summary Oral contraception as well as cigarette smoking influence haemostasis. The simulataneous effect of both on blood coagulation and fibrinolysis was studied in nine female smokers. While continuing oral contraception after a 4-week abstinence from smoking the concentration of fibrinogen, antithrombin III and alpha1-Antitrypsin decreased (P〈0.01 orP〈0.04) and of plasminogen increased (P〈0.03). The other coagulation parameters remained unchanged. Although all determinations of these parameters were in the normal range, the observed trends were statistically significant. The concentrations of the fibrinopeptide A and B 15–42 did not differ. It is concluded that the observed alteration is caused by cessation from cigarette smoking.

    Description / Table of Contents: Zusammenfassung Mit gereinigtem Kontaktaktivierungsprodukt (KAP) lassen sich unter Stasebedingungen Thromben erzeugen; hierbei treten Gerinnungsveränderungen auf, die einer Verbrauchscoagulopathie entsprechen. Es wurde daher an 92 Kaninchen unter verschiedenen Versuchsbedingungen die Frage geprüft, ob das KAP nicht nur typisch lokalisierte Thromben in einem Stasegebiet, sondern auch Gerinnungsthromben bzw. eine disseminierte intravasale Gerinnung (DIC) wie bei einer Verbrauchscoagulopathie auslösen kann. In einer ersten Versuchsgruppe erhielten die Tiere KAP als einmalige Injektion (0,8 ml/kg Körpergewicht), wobei eine V. jugularis unterbunden wurde, in einer zweiten Gruppe wurde KAP an mehreren aufeinanderfolgenden Tagen wiederholt injiziert. In einer dritten Gruppe erfolgte nach einer vorherigen Injektion von Endotoxin eine KAP-Gabe, wobei die Wessler-Technik (Ligatur einer Vena jugularis) angewandt wurde, in der vierten Versuchsgruppe wurde KAP nach Endotoxin gegeben ohne zusätzliche V. jugularis-Ligatur. Nach KAP-Injektion entstanden sowohl bei einmaliger als auch bei wiederholter Injektion Abscheidungsthromben außerhalb des Stasebereiches. Auch nach vorheriger Endotoxininjektion ließen sich Abscheidungsthromben in Lungenschlagadern und in der Herzkammer nachweisen. Disseminierte intravasale Präcipitate wie bei einer Verbrauchscoagulopathie waren nach KAP-Gabe trotz typischer Gerinnungsveränderungen nicht zu finden.
    Notes: Summary By use of purified contact activation product (CAP) it is possible to produce stasis thrombi. The changes in parameters of the clotting system are similar to those observed in consumptive coagulopathy or disseminated intravascular clotting (DIC). It was the aim of the present study to examine whether by use of CAP it would be possible to not only produce typical localized stasis thrombi but also mixed thrombi or DIC which are characteristic for consumptive coagulopathy. 92 rabbits were divided into four groups. The animals of the first group received 0.8 ml per kilogram body weight as a single intravenous injection. In the second group, CAP was injected repeatedly on 4 consecutive days. In the third group CAP was injected following preteatment with endotoxin using the Wessler technic (ligation of the jugular vein) and in the fourth group CAP was injected following endotoxin administration but without ligation of the jugular vein. In the animals which had received single or multiple injections of CAP there were agglutinative thrombi beyond the areas of stasis. Similar agglutinative thrombi were also observed in the pulmonary arteries and in the left ventricle of the heart following pretreatment with endotoxin. In spite of typical changes of coagulation parameters in all experimental animals, DIC occurred only in the endotoxin-treated animals but not following treatment with CAP alone.

    Notes: Abstract In a crystal with a free surface the translational symmetry in one direction is raised. In this case it is possible to reduce the equation of motion of the crystal to a form which is analogous to the equation of motion of a semi-infinite generalized linear chain. In this picture the surface-phonons correspond to boundary vibrations of the chain. Methods to calculate the frequencies and the “damping” constant of the surface-phonons are shown. If the surface exhibits a symmetric structure it is possible to classify the frequencies according to the irreducible representations of a subgroup of the surface-space-group. Model-calculations are performed for a free Si-111-surface using a six-parameter potential (fitted to dispersion curves). The change of the force constants near the surface is considered and fitted to the experiment of Ibach (ν=13.3×1012 sec−1). With the obtained weakening of the potential near the surface, dispersion-curves for surface-phonons are calculated.
