    Description / Table of Contents: Zusammenfassung Die Durchströmungsverteilung in hypotherm perfundierten Nieren wurde durch Injektion einer Silikongummilösung sichtbar gemacht. A. In einer vergleichenden Untersuchung am Hund konnte gezeigt warden, daß sich Nieren in gleicher Weise pulsierend und nichtpulsierend konservieren lassen. B. Humannieren warden bis zu 96 Std nichtpulsierend perfundiert: es fand sich trotz des extrem niedrigen Perfusionsdruckes von 20 mm Hg eine gleichmäßige Perfusion von Mark und Rinde. C. In Nieren ohne ausreichende Sofortfunktion war nur eine geringe Rindenperfusion nachweisbar.
    Notes: Summary The intrarenal flow distribution in kidneys perfused under hypothermia was visualized by means of silicon rubber injection. (A) It was demonstrated that pulsatile and nonpulsatile perfusion yield equivalent results. (B) After nonpulsatile perfusion of human cadaver kidneys for up to 96 hr a uniform intrarenal flow distribution was found although an extremely low perfusion pressure (20 mm Hg) was used. (C) In kidneys that showed poor function immediately after transplantation the cortex was only slightly perfused.

    Notes: Abstract We have carried out a high resolution study of odd20Ne(ns, nd J=0, 1, 2, 3, 4) Rydberg states, using transverse resonant two photon laser excitation of metastable20Ne(3s, 1s 5) atoms in a highly collimated beam. Transition energies of more than 500 levels with principal quantum numbers up ton=80 have been determined with an accuracy of better than 100 MHz relative to the metastable level. Energy independent MQDT-parameters have been extracted from fits to the experimental data near the20Ne+(2 P 3/2)-threshold. The simultaneous analysis of Rydberg series with different total angular momenta provides new insight into the Coulomb and exchange interactions governing the spectrum of neon.
