    Description / Table of Contents: Abstract The reaction of the quinisatin-aminals1, 2, and10 with phenol in acetic acid in the presence of H2SO4 gives the carbinols5, 6 and12., These compounds are reduced with Zn/HCl to yield 4-hydroxy-3-p-hydroxyphenyl-2-quinolones (7, 8, and13). The condensation of quinisatin-hydrate3 with ethyl malonate to15 is catalyzed with morpholine. The reaction of3 with 2-picoline gives17.
    Notes: Zusammenfassung Die Reaktion der Chinisatin-aminale1, 2 und10 mit Phenol in Eisessig/H2SO4 gibt die Carbinole5, 6 und12, die mit Zn/HCl zu den entsprechenden 4-Hydroxy-3-p-hydroxyphenyl-carbostyrilen7, 8 und13 reduziert werden. Die Kondensation des Chinisatin-hydrats (3) mit Malonester zu15 läßt sich mit Morpholin katalysieren; die Reaktion von3 mit 2-Picolin zu17 erfolgt beim Erhitzen der Komponenten.

    Notes: Abstract  We investigated 109 randomly selected frozen section specimens from lung surgery patients in a retrospective blind mode using telepathology equipment. The telepathology system applied (HISTKOM) used one ISDN B-channel and telemicroscopy with a remotely operated robotic microscope. The performance of telepathological frozen section diagnosis was compared with that of conventional frozen section diagnosis. The false-positive rate achieved was identical for both methods. The sensitivity (P=0.03), but not the specificity, was significantly lower for the telepathological method. The time needed to establish a diagnosis with the remote microscope was too high; therefore, upgrading to multichannel technology is recommended. The quality of the images transmitted was judged to be sufficient by the pathologists involved in the study. In conclusion, with further technical improvements in telemicroscopy and additional experience in telepathology, remote diagnosis seems to be feasible.

    Notes: Zusammenfassung Die Einwirkung der Fettsäurezusammensetzung des Futters auf diejenige des Fleisches und der Leber von Regenbogenforellen wurde durch eine Versuchsserie untersucht, bei der die Fische 3 Monate lang in drei verschiedenen Gruppen in Fischgehegen gehalten und gefüttert wurden. Die Fettsäuren wurden gaschromatographisch analysiert. Die Untersuchungen zeigen, daß das Futter auf die Fettsäurenzusammensetzung der Fische und der Fischleber Einfluß hat. Am deutlichsten zeigt sich dieses Verhältnis bei der Leber. Zwischen folgenden Fettsäuren des Futters und der Leber konnte eine Korrelation festgestellt werden: C 15 1= , C 16 2= , C 18 3= , C20, C 20 3= und C 20 5= . Auf den Gehalt an der für Fische typischen Fettsäure C 22 6= schien jedoch vor allem der Gehalt des Futters an Linolsäure einzuwirken. In allen drei Versuchsgruppen zeigte sich die Fähigkeit der Fische polyungesättigte Fettsäuren zu synthetisieren.

    Notes: Abstract To investigate the topography of morphine distribution in the human brain, a method has been developed to detect morphine immunohistochemically. In this study hippocampus tissue from victims of heroin overdose (blood morphine concentrations 220 ng/g–1500 ng/g; 6-MAM positive urine sample), known for its high concentration of μ-opiate receptors was used. The immunohistochemical staining was performed with an anti-morphine antiserum originally developed for radio-immuno-assays. In comparison with control specimens from cases of sudden death without morphine exposition or a history of heroin abuse, the brains from victims of heroin overdose showed selectively stained ganglion cells, axons and dendrites, suggesting a massive concentration of morphine in the neuronal structures.

    Description / Table of Contents: The RAMAN spectrum and the IR spectrum in the range 500-4000 cm-1 of liquid 1,8,10,9-triazaboradecaline were recorded. Major frequencies were assigned by comparing the data with the IR spectra of the corresponding N-dideuterated and 10B-labeled derivatives and by taking into consideration the expected vibrational spectrum of the compound. In accordance with the PMR spectrum, the structure of 1,8,10,9-triazaboradecaline as a bicyclic B-N-C system was confirmed; the bonding situation is discussed briefly.
    Notes: Vom 1,8,10,9-Triazaboradekalin wurde im flüssigen Zustand das RAMAN-Spektrum und das IR-Spektrum von 500-4000 cm-1 aufgenommen. Durch Vergleich mit den IR-Spektren der entsprechenden N-dideuterierten und 10B-markierten Verbindung und Berücksichtigung des Erwartungsspektrums wird eine Zuordnung zu den Grundschwingungen durchgeführt. In Übereinstimmung mit dem 1H-Kernresonanzspektrum wird die Struktur der Verbindung als bicyclisches Bor-Stickstoff-Kohlenstoff-System bestätigt. Die Bindungsverhältnisse werden kurz diskutiert.

    Description / Table of Contents: The reactions of aminoboranes with 1,3-diaminopropane and 3,3′-diaminodipropylamine are described; they offer ready access to boron-carbon-nitrogen heterocycles and to borazine derivatives. The reaction paths are discussed in terms of the planar arrangement of a N—B—N grouping.
