    Notes: Abstract Freeman Hospital, Newcastle upon Tyne restarted their non-heartbeating donor (NHBD) programme in September 1998 using machine perfusion, due to early poor results with conventional cold storage (45 % graft survival, phase II). Since then, 15 NHBD kidneys have been transplanted. The retrieval protocol consisted of in situ perfusion with a double balloon triple lumen cannula in Maastricht category II male donors age range 13–59 years. Mean primary warm ischaemic time was 24.8 min (range 10–44). All kidneys were machine perfused through a locally developed perfusion system. The viability was assessed by serial measurements of total GST (maximum acceptable limit of 200 units/l) and intrarenal vascular resistance (IRVR) was recorded. Fifteen of the 22 kidneys (68.62 %) were transplanted. Delayed graft function (DGF) was seen in ten recipients (66.6 %), two kidneys had immediate function (IF), one organ was exported, two recipients died of unrelated causes and a further seven kidneys were discarded (two had high tGST, two were infected and three had poor flow characteristics). In phase III, a success rate of 91.7 % was thus achieved, which was better than the phase II period (P = 0.027, Fisher 2-tail test). Machine perfusion has been successfully introduced in phase III to the Newcastle NHBD programme and facilitates viability assessment of NHBD kidneys.

    Description / Table of Contents: Untersuchungen zur Hydrolyse des NitrosotrichlororheniumsHydratisiertes Nitrosotrichlororhenium, Re(NO)Cl3 · xH2O, kann nicht zur wasserfreien Verbindung getrocknet werden. Dabei wird HCl abgegeben und [Re(H2O)(NO)(OH)Cl2] bzw. [Re(H2O)0,5(NO)(OH)2Cl] in Abhängigkeit von den Bedingungen gebildet. Potentiometrische Untersuchungen zeigten, daß in wäßrig-äthanolischen Lösungen der Trichlorokomplex sehr schnell zwei Äquivalente Wasserstoffionen frei setzt, während die Abspaltung der Chloridionen zeitabhängig ist. Zwei Äquivalente an Chloridionen sind jedoch im Gleichgewichtsystem vorhanden. Das dritte Chloratom ist fest an das Rheniumatom gebunden. Eine Struktur mit Chlor-Brückenbindung wird vorgeschlagen.
    Notes: Hydrated nitrosotrichlororhenium, Re(NO)Cl3 · sH2O cannot be desiccated to the anhydrous product. Hydrogen chloride is expelled and [Re(H2O)(NO)(OH)Cl2] and [Re(H2O)0.5(NO) (OH)2Cl] are produced depending on the conditions of the reactions. Potentiometric studies have indicated that in aqueous ethanolic solutions, the trichloro complex rapidly liberates two equivalents of hydrogen ions while the release of chloride ions are time dependent. Two equivalents of chloride ions are, however, present in a equilibrium system. The third chlorine atom is rigidly bound to the rhenium atom. A chloride bridged structure has been proposed.

Beim Überleiten von NO bei 220°C über Phenanthroliniumhexa-halogenorhenat(IV) wird Nitrosylhalogenid, Halogenwasserstoff und [Re(NO)(phen)Cl3] bzw. [Re(NO)(phen)Br3] gebildet.
    Notes: Nitric oxide reacts with hydrated ReO2 in aqueous suspension at 70-80°C to produce quantitatively Re(NO)(OH)3, ReO4- and NH4+. [Re(NO)Cl5]2- and ReO4- are produced in stoichiometric quantities by the reaction of either NO with ReO2 suspension in 6 N HCl or by the action of a mixture of NO and HCl with an aqueous ethanolic or aqueous suspension of ReO2 at 70-80°C. Passage of NO over 1,10-phenanthrolinium hexahalorhenate(IV) at 220°C produces nitrosyl halide, hydrogen halide and [Re(NO) (phen)Cl3] or [Re(NO)(phen)Br3].
