    Notes: Summary 1. 3H-leucine and3H-tyrosine were added to the perfusion medium of isolated bovine adrenal glands in order to study the synthesis and secretion of radioactively labelled catecholamines and proteins. 2. Various times after the injection of the labelled amino acids the soluble proteins of the microsomal fraction were isolated and subjected to polyacrylamide gel electrophoresis in three different buffer systems. The distribution of protein-bound radioactivity within the gels was determined. Most of the label was found to be confined to proteins which behaved like the specific soluble proteins of chromaffin granules, i.e. the chromogranins. 3. Stimulation of the adrenal gland with carbachol induced a release of catechol-amines, protein, and protein-bound radioactivity. In the absence of Ca2+ the secretion of all these components was abolished. The highest specific radioactivity of the proteins secreted upon stimulation was reached 4 h after the injection of the labelled precursors. The labelled proteins, secreted upon stimulation, could be identified as chromogranins. 4. Carbachol induced the release of highly labelled catecholamines after the injection of3H-tyrosine. The highest specific radioactivity of these catecholamines was already observed at the first stimulation with carbachol i.e. 30 min after3H-tyrosine. 5. These results demonstrate that in isolated bovine adrenal glands radioactively labelled chromogranins and catecholamines can be synthesised and can be secreted upon stimulation with carbachol.

    Notes: Summary 1. The subcellular distribution of newly synthesised catecholamines, nucleotides and proteins was investigated in bovine adrenal medulla. 3H-tyrosine, 3H-leucine and 32P-phosphate were used as radioactive precursors (“pulse label”). 2. Already 3 min after infusion of 3H-tyrosine the bulk of the labelled catecholamines was present in the “large granules” (mitochondria, lysosomes and chromaffin granules). In the fractions from the density gradient the distribution of the labelled and the total catecholamines was the same. Analogous results were obtained at longer time intervals. 3. 3 min after infusion of 32P-phosphate the labelled nucleotides present in the “large granules” were concentrated in the mitochondrial fraction. At longer time intervals after infusion of 32P-phosphate (45 min and 4h) chromaffin granules had accumulated a larger portion of the labelled nucleotides, mitochondria contained less. 4. After infusion of 45Ca2+, the isotope present in the large granules was found to be concentrated in the mitochondria and in chromaffin granules. 5. After infusion of 3H-leucine the soluble proteins of the adrenal medulla rapidly became labelled. 4 h after 3H-leucine newly synthesised proteins could be demonstrated in a particle which was present in the large granule fraction and which equilibrated in density gradients in a position corresponding to 1.6 M sucrose. This particle can be differentiated from mitochondria, microsomes, lysosomes and the bulk of the chromaffin granules. The labelled soluble proteins of this particle were identified as chromogranins. It seems likely that this particle represents a newly formed chromaffin granule which differs in its properties from the bulk of mature granules. The membrane proteins of this particle were not significantly labelled. 6. After infusion of 32P-phosphate the phospholipids of the adrenal medulla became labelled. The subcellular distribution of these phospholipids was similar to that of a microsomal marker enzyme, glucose-6-phosphatase. Lysoclecithin was not significantly labelled. 7. In the light of these results the subcellular events leading to the formation of complete chromaffin granules are discussed.

    Description / Table of Contents: Schallemissionsprüfung von Wärmetauschern des Reaktors SaphirDie Schallemissionsanalyse ist eine zerstörungsfreie Prüfmethode, die zur Untersuchung und Überwachung von Strukturen und druckführenden Komponenten verwendet wird. Das Ziel der Messung am 5 MW Forschungsreaktor Saphir war die Untersuchung und Auswertung der hohen Betriebsgeräusche in den Wärmetauschern des Kühl-systems.Die Ergebnisse zeigten, daß von den 9 Wärmetauschern, die in 3 Gruppen angeordnet sind, 5 Wärmetauscher ein hohes Betriebsgeräusch aufweisen. Die Ursache ist auf die Schwingung der Rohrbündel in Wärmetauschern beim Durchfluß des Pool-Wassers zurückzuführen. Die axiale Ortung bestätigte, daß die Geräusche von mehreren Quellen verursacht werden.
    Notes: The acoustic emission technique is a non-destructive testing method used for inspection and surveillance of structures and pressurized components. In particular, the purpose of the measurement on the 5 MW research reactor SAPHIR was to investigate and evaluate the abnormally high noise levels during operation of the heat exchangers of the cooling system.The results showed that 5 heat exchangers out of the total of 9 (assembled in 3 groups) were responsible for the higher noise level. This is probably due to some abnormal vibration of the tube bundles therein, caused by the through-flow of the pool water. Indeed, attempts of localizing the source showed that there must be several, distributed sources.

    Notes: In Deutschland geht der Patentschutz über das in den Patentansprüchen unmittelbar Aufgeführte hinaus. Dieser erweiterte Schutz des Erfinders führt jedoch zu einer gewissen Rechtsunsicherheit. Die Begriffe „Gegenstand der Erfindung“, „Stand der Technik“, „verschlechterte Ausführungsform“ und der „allgemeine Erfindungsgedanke“ werden hier daher neben anderen genauer definiert. An Beispielen wird gezeigt, wie die Interessen von Erfinder und Patentkläger zu umgrenzen sind und nach welchen Grundsätzen der Schutzumfang von Patenten durch die Gerichte im Verletzungsprozeß ausgelegt wird.
