    Notes: Summary To investigate the patterns of catecholamine release in the brain, the hypothalamus of conscious, freely moving rats was superfused through a push-pull cannula with artificial cerebrospinal fluid and the catecholamines dopamine, noradrenaline and adrenaline were determined in the superfusate radioenzymatically. Superfusate was continuously collected in time periods of 20 min for at least 20h. Dopamine, noradrenaline and adrenaline release rates fluctuated according to an ultradian rhythm with a frequency of 1 cycle/92 min (dopamine and noradrenaline) or 99 min (adrenaline). Additionally, the three catecholamines were released according to an ultradian rhythm with the following frequencies: noradrenaline and adrenaline 1 cycle/ 12 h, dopamine 1 cycle/8 h. The release rates of dopamine and adrenaline were similar during light and dark periods, while the release rate of noradrenaline in the dark period was slightly lower than that during the light period. It is concluded that in the hypothalamus of the conscious rat the release rates of dopamine, noradrenaline and adrenaline fluctuate according to two ultradian rhythms with different frequencies.

    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.
