    Notes: Abstract Infrared spectra of nitrogen doped Czochralski-grown silicon indicate absorption lines in addition to the well-known lines of local modes of oxygen, carbon and nitrogen centers. The most prominent lines of them can be shown to be correlated with certain oxygen and nitrogen concentrations. These lines are, therefore, thought to arise from N-O complexes and are discussed in the context of an O-induced disturbance of N2-pair vibrations. The results of preliminary investigations on the stability of such complexes are also reported.

    Description / Table of Contents: Zusammenfassung In einer retrospektiven Untersuchung werden die Ergebnisse von 270 Patienten analysiert, die zwischen 1978 und 1985 wegen Blutungen aus Ulcera oder Erosionen behandelt wurden. 192 Patienten (71%) bluteten aus chronischen Ulcera, 49 (18%) aus Streßläsionen und 29 (11 %) aus Arzneimittelulcera, hiervon wiesen 53% eine Sickerblutung Typ Forrest 1b auf. Die Kliniksletalität fiel während dieser 8 Jahre von 18% auf 8%. Parallel hierzu besserte sich die Prognose von Sickerblutungen, die zunehmend häufiger mit Secretin bzw. Somatostatin behandelt wurden. Bei diesem Blutungstyp reduzierte sich die Anzahl der Notfalloperationen von 44% im Jahre 1978 auf zuletzt 10% und die Letalitätsrate von 22% auf 5%.
    Notes: Summary The results of 270 patients, admitted from 1978 to 1985 because of upper gastrointestinal bleeding from ulcers or erosions were analysed retrospectively. Chronic peptic ulcers were the most common bleeding sites (192 patients, 71%). 49 patients (18%) bled from acute lesions and 29 (11%) from drug-induced ulcers. 53% of all patients exhibited an oozing hemorrhage (type Forrest 1b) during emergency endoscopy. Within the eight-year-period hospital mortality dropped from 18% to 8%. In parallel the prognosis of oozing bleeding improved. In this period the patients were more often treated with secretin or somatostatin. Hence the frequency of emergency operations for patients with oozing bleeding could be reduced from 44% in 1978 to 10% in 1985 and the death rate from 22% to 5%.
