    Description / Table of Contents: Zusammenfassung An sechs nembutalanaesthesierten Kaninchen wurde der Einfluß von intravenös appliziertem Clonidin auf die Durchblutung verschiedener Gewebe untersucht. Als Kontrollgruppe dienten sechs weitere Tiere, die die gleiche Menge physiologischer Kochsalzlösung erhielten. Der Blutfluß wurde kurz vor der Medikamenten- bzw. Placeboverabreichung und 15, 30 und 45 min. danach mit der Partikelverteilungsmethode bestimmt. Die meisten Gewebe zeigten 15 min. nach der Clonidininjektion eine deutliche Abnahme ihrer Durchblutung, was nach Kochsalzgabe nicht in der gleichen Weise der Fall war. In der Kochsalzreihe traten erst nach 30 min., noch stärker nach 45 min. Reduktionen der Gewebedurchblutung auf. Von der flowsenkenden Wirkung des Clonidins waren Lunge, Dünndarm, Aderhaut, M. triceps, weiße Substanz, Haut, Ciliarkörper, Iris und Rückenmark betroffen. Entgegengesetzte Reaktionen unter Clonidin zeigten Leber (A. hepatica), Retina und Nervus opticus.
    Notes: Summary The effect of i.v. administered clonidine on the blood flow through different tissues was investigated in six rabbits which had been anaesthetized with NembutalR. Six additional animals served as controls and received an equal quantity of a physiological sodium chloride solution. The blood flow was determined by means of radioactively labelled microspheres just before as well as 15, 30 and 45 min after the administration of the drug or the placebo respectively. In most of the investigated tissues a considerable decrease in blood flow was observed 15 min after the injection of clonidine, whereas no effect was to be seen after administration of sodium chloride. For the first time after 30 min, and even more after 45 min the blood flow diminished as well in the control group. The flow-decreasing effect of clonidine occured in lung, skin, choroid, the small intestine, the triceps muscle, the ciliary body, iris and white matter, whereas the opposite reaction was observed in liver (hepatic artery), retina and the optic nerve.

    Notes: Abstract 177g Lu and177m Lu with half lives of 6.8d and 161d, respectively, were implanted into iron foils and oriented at low temperatures. From the temperature dependence of the anisotropies of severalγ-rays the magnetic moment of theI π=23/2− three quasiparticle isomeric state177m Lu was determined asμ=3.3±0.3 nm. It is shown that the additivity relation for magnetic moments is well fulfilled for four high spin multiparticle states in this mass region. Using the known magnetic moment of the ground state a value of ¦H¦=377±15 kG was derived for the internal field of Lu in Fe for our sample.

    Notes: Abstract The level structure of the odd-odd isotopes192Au and194Au was investigated by in-beamγ-ray spectroscopy with the reactionnatIr(α, 3nγ). Several new energy levels could be established in both isotopes.

    Notes: Abstract Half-lives of 7− and 12+ states in190, 192Pt and 25/2− states in191, 193Pt were measured with the in-beam direct timing method. Time spectra of conversion electrons were recorded relative to the beam bursts of the Bonn cyclotron. The values forB(E2, 12+ → 10+) in190, 192pt are compared with available calculations for pure (vi 13 2/−2 ) rotation-aligned configurations. The systematics of theB(E2) values within the semi-decoupled negative paraity bands is discussed. An attempt has been made to measure the half-life of the 7− level in188Pt. The still existing inconsistences are briefly discussed.
