    Identification of Enteramine, the Specific Hormone of the Enterochromaffin Cell System, as 5-Hydroxytryptamine (1952)
    [s.l.] : Nature Publishing Group

    Notes: [Auszug] Chemically speaking, the specific product of the enterochromaffin cells was considered by histologists, at different times, as an o-dihydroxybenzene or a m-dihydroxybenzene derivative. Already in 1946, however, one of us1 had emphasized the probable indolic nature of the substance, on the basis of ...

    Notes: [Auszug] So far, acetone extracts of the skin of Bufo bufo bufo, Discoglossus pictus, Rana esculenta, Hyla arberea, Salamandra maculosa and Triton cristatus have been examined. The parathyroid glands of Bufo were extracted separately from the remaining skin. After cleaning with petroleum ether and suitable ...

    Observations on the metabolism of endogenous 5-hydroxytryptamine (enteramine) in the rat (1954)
    Springer

    Notes: Zusammenfassung Der Rattenurin enthält 1,34µg 5-Hydroxyindolyl-essigsäure je Kubikzentimeter (=81,4µg/kg/24 h). Daraus ist zu berechnen, dass in der Ratte täglich 216–236µg/kg 5-Hydroxytryptamin metabolisiert werden. Dies bedeutet, dass das Blutplättchen-5-HT alle 3–4 h und das Gesamt-5-HT des Organismus alle 12–14 h erneuert werden wird. Die erhaltenen quantitativen Daten sind hauptsächlich im Hinblick auf die fragliche Bildungsstelle des 5-HT und die biologische Bedeutung der Substanz selber wichtig.

    Notes: [Auszug] The fluorescent reaction may therefore be of value in tracing small quantities of 5-hydroxytryptamine in tissue extracts. The diazotized p-nitraniline reagent may also assist, since hydroxyindolealkyl-amines (for example, 5-hydroxytryptamine, bufotenine and bufotenidine) give an orange-brown colour ...

    Notes: [Auszug] Pharmacological and chemical investigations (colour reactions) showed that octopamine was probably a monophenol derivative, with an amine group in the side-chain; thus the possibility of identifying it with N-methyltyramine was considered. The existence of octopamine in the salivary extracts of ...

    Notes: Zusammenfassung Acetonextrakte der hinteren Speicheldrüsen vonOctopus vulgaris undEledone (E. moschata undE. Aldrovandi), der Hypobranchialdrüse vonMurex trunculus undMurex brandaris, sowie der Milz und der Magen- und Dünndarmschleimhaut von Säugetieren verhindern merkwürdigerweise die Diurese der Ratte, des Hundes, des Meerschweinchens, des Frosches, der Kröte und des Menschen (gesund und krank anDiabetes insipidus). Die diuresehemmende Wirkung solcher Extrakte ist ausschließlich ihrem Enteramingehalt zuzuschreiben. Enteramin hemmt nicht nur die normale und die Wasserdiurese, sondern auch die durch Salze, Xanthinderivate und Quecksilberverbindungen erzeugte Diurese.

    Notes: Zusammenfassung Konzentrierte Extrakte der hinteren Speicheldrüsen vonOctopus vulgaris wurden auf Papier chromatographiert. Zahlreiche Flecke konnten durch chemische und teilweise auch durch biologische Reaktionen differenziert werden. Hievon waren zwei sicher enteraminhaltig (Fleck III = Enteramin A; Fleck IX = Enteramin I). Drei andere enthalten wahrscheinlich enteraminähnliche Substanzen (Flecke I, II, IV). Die an mehr als 20 Farbreaktionen erhobenen Befunde werden kurz erörtert.
