    Notes: Various cases of human combined immunodeficiency together with adenosine-deaminase deficiency have been described in the last 3 years. The congenitally thymus-less (nu/nu) mouse could be presumed to serve as a possible laboratory model for examination of this combination of enzymatic deficiency and immunodeficiency. The present investigations, however, show similar isozyme pattern and enzymatic activity of nude mice and healthy Balb/c and C3H mice. Adenosine-deaminase deficiency cannot be the cause of the immunodeficiency of the nude mouse.

    Description / Table of Contents: Zusammenfassung Die Ratte bietet als Versuchstier im Rahmen der Transplantationsforschung von Organen gegenüber größeren Tieren wesentliche Vorteile, besonders in genetisch-immunologischer Hinsicht. Es werden unterschiedliche mikrochirurgische Techniken zur Herstellung der Gefäß- und Ureteranastomosen angegeben und auf Vor- und Nachteile hin miteinander verglichen. Die direkte Kanülierung der Nierengefäße mit Polyäthylenkathetern ist möglich; sie weist den Nachteil der frühen Thrombosierung der kanülierten Gefäße auf. Dagegen sind die genähten Gef äßanastomosen so lange offen, bis im Stadium fortgeschrittener Abstoßungsreaktionen ein Zirkulationsstillstand erreicht wird, and es dabei zur Ausbildung von Thrombosen in den Nierengefäßen kommt. Die Empfängerratten über-leben die AbstoBungskrise des Transplantats mit einer körpereigenen Niere für Wochen and Monate. Eine immunsuppressive Therapie wurde nicht durchgeführt, da es hier zunächst um technische Probleme der Nierentransplantation bei der Ratte ging, die wegen des kleinen Bauchsitus anfänglich recht schwierig war.
    Notes: Summary In transplantation research of organs the rat is superior to bigger animals, particularly in genetic-immunologic respects. Various microsurgical techniques of vessel and ureter anastomoses are discussed and compared as to their advantages and disadvantages. Direct cannulation of the renal vessels is possible with polyethylen catheters. The disadvantage of this method is the early thrombosis of the cannulated vessels. The sutured vessel anastomoses remain open until, in the stage of advanced rejection, circulatory stillstand is reached causing thrombosis of renal vessels. The recipient rats survived the rejection crisis of the transplant for weeks and months provided they still had one kidney of their own. Immuno-suppressive therapy was not initiated because of the special technical interest in renal trans-plantation in the rat.

    Notes: Abstract Intensity dips in the output power of a multimode He/Ne-Laser as a function of an axial magnetic field have been measured up to a field strength of 600 Gauß. These intensity dips are appearing if the Zeeman-splitting is equal to the frequency separation of different modes. The effect is used for Zeeman-spectroscopy. A discussion of the observed phenomena is given based on Lamb's Theorie. The measured value for the Landé-Factor of the 2p 4 Ne-level isg j (2p 4)=1.3005 (±0.2%).

    Notes: Abstract TheM 4, 5 N 4, 5 N 4, 5 Auger spectrum of xenon has been measured with high resolution. Theoretical line intensities and relative line energies for this spectrum have been calculated applyingjj coupling to the initial states and intermediate coupling and configuration interaction to the final states. Two facts indicate that correlation effects are only small in the present case: The application of configuration interaction gives only small changes in line intensities and the experimental line intensities are found to be in good agreement with theoretical results, calculated without configuration interaction.

    Notes: Abstract Saturation induced minima of the output power of a He/Ne-laser appear if Zeeman splitting equals the frequency separation. These minima have been investigated as a function of pressure. The results show pressure broadening caused by velocity changing and alignment destroying collisions. In contrast to Lamb-dip measurements the effect of phase changing collisions on collision broadening is negligible.

    Notes: Abstract The shape of zero field mode crossing resonances has been investigated both theoretically and experimentally. Taking into account the effect of collisions, the resonance shape is given generally by superposition of four Lorenzians. Two of them are caused by the aligned laser levels (ifJ≧1), the other two are produced by phase destroying collisions. Investigations of the zero field mode crossing resonances of the 2s 2→2p 1(λ=1.52μm) and 3s 2→2p 4 (λ=633nm) Ne laser transition revealed deviations of the measured data from a Lorentz profile. By computer fitting both the alignment relaxation rate $$\gamma _{2s_2 } $$ (2) and the relaxation rate of the optical coherence $$\gamma _{2s_2 ,2p_1 } $$ was obtained from one resonance curve. An investigation of the relaxation rate of the optical coherence as a function of the Ne pressure yields the pressure broadening constant (7±3) MHz/Torr and the natural linewidth 1/2 $$\tfrac{1}{2}(\gamma _{2s_2 } + \gamma _{2p_1 } ) = (18.8 \pm 1.7)$$ MHz which are in agreement with inverted Lamb dip measurements.

    Notes: Abstract In the linearly polarized radiation field of a 442 nm He-Cd laser containing a natural isotope mixture, saturation-induced mode-crossing signals of the 4d 95s 2 2 5/2 state of Cd II are observed due to the even as well as the odd isotopes. The signal width of about 10−4 T yields high resolution. Thus the signal splitting respective to the magnetic quantum number can be resolved. Theg J - andg F -factors of the2 D 5/2 state are determined as follows:g J=1.1980±0.0036,g F(F=2)=1.397±0.008,g F(F=3)=1.002±0.009.
