    Notes: Summary There is experimental evidence that inhibition of cyclooxygenase with nonsteroidal anti-inflammatory drugs may decrease cholesterol gall-stone formation and mitigate biliary pain in gall-stone patients. The mechanisms by which NSAIDs exert these effect are unclear. In a prospective, controlled clinical trial we examined the effects of oral indomethacin on the composition of human gall-bladder bile. The study included 28 patients with symptomatic cholesterol or mixed gallstones. Of these, 8 were treated with 3 × 25 mg indomethacin daily for 7 days prior to elective cholecystectomy while 20 received no treatment and served as controls. Bile and tissue samples from the gallbladder were obtained during cholecystectomy. Indomethacin tissue levels in the gallbladder mucosa, as assessed by HPLC, were 1.05±0.4 ng/mg wet weight, a concentration known to inhibit effectively cyclooxygenase activity. Nevertheless, no differences between the treated and untreated groups were found in the concentrations of biliary mucus glycoprotein (0.94±0.27 versus 0.93±0.32 mg/ml) or total protein (5.8±0.9 versus 6.4±1.3 mg/ml), cholesterol saturation (1.3±0.2 versus 1.5±0.2), or nucleation time (2.0±3.0 versus 1.5±2.0 days). However, biliary viscosity, measured using a low-shear rotation viscosimeter, was significantly lower in patients receiving indomethacin treatment (2.9±0.6 versus 5.6±1.2 mPa.s; P 〈 0.02). In conclusion, in man oral indomethacin decreases bile viscosity without alteration of bile lithogenicity or biliary mucus glycoprotein content. Since mucus glycoproteins are major determinants of bile viscosity, an alteration in mucin macromolecular composition may conceivably cause the indomethacin-induced decrease in biliary viscosity and explain the beneficial effects of nonsteroidal anti-inflammatory drugs in gallstone disease.

    Description / Table of Contents: Zusammenfassung Die Einschätzung der Handlungsfähigkeit eines tödlich Vergifteten kann bei der Tatrekonstruktion sehr bedeutsam sein, insbesondere bei der Frage „Selbst- oder Fremdbeibringung des Giftes“. Klinische Publikationen gehen hierauf kaum ein. Deshalb wurden 27 Fälle tödlicher oraler Intoxikationen mit Cyan-Verbindungen der rechtsmedizinischen Institute Würzburg, Hamburg, München, Berlin (FU), Tübingen, Essen und Leipzig, bei denen eine Aussage zur Handlungsfähigkeit des später Verstorbenen möglich war, sowie die dazugehörigen polizeilichen und staatsanwaltschaftlichen Akten unter dieser Fragestellung ausgewertet. Ergebnis: in der Mehrzahl der Fälle betrug die Handlungsfähigkeit nur wenige Sekunden bis maximal 1 bis 2 Minuten. Im Untersuchungsgut und in der Literatur kamen allerdings auch Fälle vor, bei denen die Handlungsfähigkeit über ca. 5 bis 10 min erhalten war. Die Ergebnisse der Arbeit sollen dem Gutachter als Leitlinie bei der Klärung einschlägiger Fälle dienen.
    Notes: Abstract An accurate assessment of the duration of the ability to act of a victim of lethal poisoning can be of crucial importance in reconstructing the cause of the poisoning, especially in determining whether the poison was taken by the victim or given by another. Clinical studies have scarcely dealt with this problem. We therefore investigated 27 cases of lethal oral intoxication with cyanogen compounds on file at the university institutes of forensic medicine in Würzburg, Hamburg, Munich, Berlin (Free University), Tübingen, Essen and Leipzig with regard to the victim’s postintoxication ability to act. In addition we examined the records of the respective police and prosecuters offices as well as the relevant literature. In most cases the ability to act lasted only a few seconds to a maximum of 1–2 min. However, in some of the 27 cases the ability to act lasted for 5–10 min, a finding which agrees with reports in the literature. The present study is intended to provide forensic expert witnesses with guidelines for clarifying similar cases of lethal oral intoxication.
