    Notes: Summary The effects of exposure to continuous light, continuous darkness, and administration of melatonin on prostatic androgen receptors in relation to pubertal development in rats were examined. Darkness produced dissimilar results between the pubertal and adult groups. Whereas the prostate weight in the pubertal group remained unaltered, it increased in the adult group. In the pubertal group exposed to darkness, plasma melatonin increased significantly, and androgen receptors declined, whereas in the adult group these receptors rose significantly with a simultaneous increment of melatonin concentration in plasma. Exposure to continuous light did not produce any effective alterations in the parameters examined. The afternoon melatonin administration showed trends similar to those seen in animals exposed to darkness. The results indicate that exposure to darkness or administration of melatonin both have age-dependent effects on prostatic androgen receptors. Exposure to darkness may interfere with the process of sexual maturation in the pubertal animal as a result of increased melatonin production.

    Description / Table of Contents: Zusammenfassung Für eine Stichprobe von 295 Patienten nach einem Suizidversuch — in 94% durch Intoxikation — zeigte das Merkmal einer schweren, ohne ärztliche Hilfe tödlich verlaufenden Vergiftung (15,3% der Gesamtstichprobe) signifikante Zusammenhänge zu Charakteristika, die in der Literatur bei Suizidenten gehäuft gefunden wurden. Die Einschätzung eines starken Sterbewunsches der Patienten (bei 47,3%) durch die Untersucher zeigte signifikante Zusammenhänge zu weitgehend den gleichen Merkmalen der untersuchten Population. Eine schwere Vergiftung sowie eine als hoch eingeschätzte Sterbeintention wiesen deutliche Zusammenhänge zu der während des stationären Aufenthaltes erfolgten und für die anschließende Weiterbehandlung vorgeschlagene Betreuung auf.
    Notes: Summary In 15.3% of 295 hospitalized suicide attempters (94% with intoxication) severe intoxication that would have had a lethal outcome without medical treatment was significantly associated with previously described factors characterizing persons who committed suicide. A strong death wish (47.3%), as judged by physicians, was highly associated with almost the same factors. A high degree of physical harm and a firm intention to die correlated significantly with the intensity of care during hospitalization and after discharge from the emergency unit.
