    Notes: Abstract A case of non-rotation of the bowel is presented wherein volvulus of the colon occurred causing acute obstruction. Spontaneous reduction following a barium enema as well as the patient's history leads us to suspect that volvulus had occurred in the past and was responsible for the intermittent nature of the patient's symptoms. This type of volvulus is distinctly different from midgut volvulus and is a rare complication of the anomaly of intestinal rotation and fixation known as non-rotation of the bowel. Efforts should be made to study patients with malrotation anomalies at a time when they are acutely symptomatic so that intermittent volvulus such as shown here is not overlooked.

    Description / Table of Contents: Summary After a single oral dose of 4 mg/kg indomethacin (IDM) to sodium and volume depleted rats plasma renin activity (PRA) and systolic blood pressure fell significantly within four hours. In sodium repleted animals indomethacin did not change systolic blood pressure (BP) although plasma renin activity was decreased. Thus, indomethacin by inhibition of prostaglandin synthesis may diminish the blood pressure maintaining effect of the stimulated renin-angiotensin system in sodium and volume depletion.
    Notes: Zusammenfassung Nach einer einmaligen oralen Gabe von 4 mg/kg Indometacin kam es innerhalb von 4 h bei Natrium- und Volumenverarmten Ratten zu einem signifikanten Abfall der Plasma-Reninaktivität und des systolischen Blutdrucks. Bei normalen Ratten führte die Indometacingabe lediglich zur Erniedrigung der Plasma-Reninaktivität ohne Beeinflussung des arteriellen Blutdruckes. Es wird deshalb angenommen, daß Indometacin über eine Hemmung der Prostaglandinsynthese den Blutdruck stabilisierenden Effekt des Renin-Angiotensin-Systems bei Natrium- und Volumenverarmung, vermindern kann.

    Description / Table of Contents: Crystal Structure of CaZn2(OH)6 · 2 H2OThe electrochemical oxidation of zinc in a zinc/iron-pair leads in an aqueous NH3 solution of calciumhydroxide at room temperature to colourless crystals of CaZn2(OH)6 · 2 H2O. The X-ray structure determination was now successful including all hydrogen positions.P21/c, Z = 2, a = 6.372(1) Å, b = 10.940(2) Å, c = 5.749(2) Å, β = 101.94(2)° N(F2o ≥ 3σF2o) = 809, N(Var.) = 69, R/RW = 0.011/0.012The compound CaZn2(OH)6 · 2H2O contains Zn2+ in tetrahedral coordination by OH- and Ca2+ in octahedral coordination by four OH- and two H2O. The tetrahedra around Zn2+ form corner sharing chains, three-dimensionally linked by isolated polyhedra around Ca2+. Weak hydrogen bridge bonds result between H2O as donor and OH-.
    Notes: Die elektrochemische Oxidation von Zink in einem Zink/Eisen-Paar führt in einer wäßrigen NH3-Lösung von Calciumhydroxid bei Raumtemperatur zu farblosen Kristallen von CaZn2(OH)6 · 2 H2O. An ihnen wurde röntgenographisch die Struktur jetzt einschließlich aller H-Lagen bestimmt.P21/c, Z = 2, a = 6,372(1) Å, b = 10,940(2) Å, c = 5,749(2) Å, β = 101,94(2)° Z(F2o ≥ 3σF2o) = 809, Z(Var.) = 69, R/RW = 0,011/0,012In CaZn2(OH)6 · 2 H2O ist Zn2+ tetraedrisch von OH- und Ca2+ oktaedrisch von vier OH- und zwei H2O umgeben. Die Tetraeder um Zn2+ bilden Ketten über gemeinsame Ecken, die durch voneinander isolierten Oktaedern um Ca2+ dreidimensional verknüpft werden. Es liegen schwache H-Brückenbindungen von H2O als Donator zu OH- vor.
