    Notes: Summary The posterior hypothalamus of anaesthetized cats was superfused with a push-pull cannula and the release of the endogenous catecholamines noradrenaline, adrenaline and dopamine was determined in the superfusate. The rate of release of the three catecholamines followed an ultradian rhythm, the time interval between two adjacent phases of high rate of release being about 70 min. Pretreatment of the animals with reserpine decreased the levels of catecholamines in the hypothalamus and rest of the brain and reduced their rate of release into the superfusate. Hypothalamic superfusion with superfusing fluid of high concentration of potassium and low concentration of sodium enhanced the rate of release of noradrenaline and adrenaline; this effect was abolished when the hypothalamus was superfused with calcium-free solution. Electrical stimulation of the locus coeruleus ipsilateral to the superfused hypothalamus increased the release of noradrenaline and adrenaline, stimulation of the contralateral locus coeruleus enhanced the release of noradrenaline, adrenaline and dopamine. In both cases, the rate of release of adrenaline was enhanced to a lesser extent than the rate of release of noradrenaline. The release of noradrenaline and adrenaline was increased to a higher extent on stimulation of the ipsilateral locus coeruleus than on stimulation of the contralateral one.

    Description / Table of Contents: Zusammenfassung In drei Fällen wird ein an Leichen, die nach längerer Liegedauer in wassergefüllten Badewannen aufgefunden wurden, beobachtetes, parallel zur Wasseroberfläche verlaufendes und bis zu etwa 1 cm breites Hauptphänomen berichtet. Im Gegensatz zur umgebenden Haut zeichnet sich die streifenförmige Marke durch Blässe und deutlich geringer ausgeprägte postmortale Veränderungen wie Fäulnis aus. Zur Abklärung wurden an einem Modellfall Temperaturmessungen durchgeführt. Die Ergebnisse lassen die streifige Hautabblassung als thermisches Grenzzonenphänomen erklären. Dieses besitzt auch eine forensische Wertigkeit: das Zeichen bezeugt ein längeres Verweilen des Leichnams in der entsprechenden Lage, bietet eine Aussage betreffend die Höhe des Wasserspiegels und gestattet eine Rekonstruktion der ursprünglichen Position nach Lageveränderung, ist aber kein Vitalitätszeichen.
    Notes: Summary In three cases a phenomenon is reported, seen on the skin of bodies found dead after a longer time of lying in bathtubs filled with water. The sign was parallel to the surface of the water and showed a breadth up to about 1 cm. Contrary to the surrounding skin, the mark was characterized by paleness and clearly less distinct formation of postmortem alterations as putrefaction. Searching for an explanation, temperature measurements were performed in model. The results showed the marginal paleness of the skin to be a thermal phase transition phenomenon. This mark has a forensic message too: it demonstrates a longer remaining of the corpse in the corresponding position, is a statement concerning the high of the water level, and allows a reconstruction of the original situation after manipulation, but is no sign of vital reaction.
