    Notes: Abstract We discuss the short-and long-term perspectives of the CRESST (Cryogenic Rare Event Search using Superconducting Thermometers) project and present the current status of the experiment and new results concerning detector development. In the search for elementary particle dark matter, CRESST is presently the most advanced deep underground, low-background, cryogenic facility. The basic technique involved is to search for WIMPs (Weakly Interacting Massive Particles) by the measurement of nonthermal phonons, as created by WIMP-induced nuclear recoils. Combined with our newly developed method for the simultaneous measurement of scintillation light, strong background discrimination is possible, resulting in a substantial increase in WIMP detection sensitivity. This will allow a test of the reported positive evidence for a WIMP signal by the DAMA Collaboration in the near future. In the long term, the present CRESST setup permits the installation of a detector mass up to 100 kg. In contrast to other projects, CRESST technology allows the employment of a large variety of detection materials. This offers a powerful tool in establishing a WIMP signal and in investigating WIMP properties in the event of a positive signal.

    Notes: Abstract In 9 dogs, whose maximum gastric acid response to pentagastrin was evoked by 6 μg/kg, the total gastric secretion as well as the peak gastric secretion was enhanced by amodiaquine. The optimum dose of this antimalarial drug was 2 mg/kg, whereas 0.25 mg/kg were without effect and 3 mg/kg reduced already the augmentation of gastric secretion by this substance. The increase in acid output by amodiaquine was greater than that in volume. The total secretion was more enhanced than the peak secretion, which means a longer duration of the amodiaquine potentiated gastric secretion elicited by pentagastrin, than that without application of amodiaquine contrary to that stimulated by exogenous histamine. Amodiaquine itself did not stimulate gastric acid secretion, in contrast to prostigmine and carbachol. Thus amodiaquine seemed not to enhance gastric secretion by a direct or indirect parasympathomimetic action. The question whether amodiaquine acted on gastric secretion in a specific way and not by parasympathomimetic effects, led to investigations in several exocrine glands. In salivary glands, amodiaquine did neither stimulate the secretion in all doses investigated nor did it enhance the pilocarpine and acetylcholine induced salivation with any significance and regularity. Also the pancreatic and biliary secretion was neither stimulated by amodiaquine nor was the secretin induced secretion of the pancreas and liver augmented by amodiaquine. Thus the enhancing effect of this drug on the histamine and pentagastrin stimulated gastric secretion was very likely specific for the gastric mucosa and not due to a parasympathomimetic action of the drug. In contrast to the findings in various exocrine glands of the gastrointestinal tract, the arterial hypotension following the i.v. injection of acetylcholine was increased specifically by a preceeding i.v. injection of amodiaquine, whereas the equi-effective actions of histamine, serotonin and bradykinin as well as the hypertension by epinephrine and norepinephrine were not influenced by amodiaquine. This specific effect of the antimalarial drug very probably was not caused by an inhibition of the unspecific choline esterase in the blood. Since in exocrine glands no evidence could be found for a parasympathomimetic action or other modes of action of amodiaquine, it seemed probable that amodiaquine potentiated the histamine and pentagastrin stimulated gastric secretion by an inhibition of histamine methyltransferase in vivo.

    Description / Table of Contents: Zusammenfassung Eine prospektive, kontrollierte Studie über eine standardisierte Operationsauswahl und Operationstechnik der selektiven Vagotomie wurde an 65 Patienten mit kompliziertem und unkompliziertem chronischem Duodenalulcus durchgeführt. Operationstechnik, Ziel, Vorbereitung und Durchführung der Studie, Operateure und Nachuntersucher, Patientenauswahl und die Methoden der Nachuntersuchung werden im Detail beschrieben. In einem Zeitraum von 6–12 Monaten postoperativ wurden 60 Patienten nachuntersucht, 4 Patienten waren verstorben, 1 Patient nicht auffindbar. Die operative Letalität betrug 0%, intra- und postoperative Komplikationen wurden bei 2 bzw. 15% der Patienten beobachtet, 2 Rezidive wurden festgestellt. Das klinische Allgemeinbefinden war bei 85% der Patienten gut, bei 93% befriedigend. Leichte Diarrhoen wurden bei 8%, schwere in keinem Fall beobachtet. Dumping trat dagegen in 30% der Fälle auf, war aber immer nur geringfügig. Positive Insulinteste nach verschärften Hollander-Kriterien wurden in 27% der Fälle gefunden. Die Basalsekretion wurde um 83–98% reduziert, die mit Pentagastrin maximal stimulierte Sekretion um 51% nach Vagotomie und Pyloroplastik, um 87% nach Vagotomie und distaler Antrektomie (BI) und um 95% nach Vagotomie und Antrektomie (BII). Die vorgelegte prospektive Studie stellt den ersten Teil einer Untersuchung dar, die zur Beurteilung verschiedener Vagotomieformen in der chirurgischen Therapie des chronischen Duodenalulcus herangezogen werden soll. Die Frühergebnisse dieser Studie rechtfertigen aber vorläufig die Empfehlung einer individuellen Anwendung der selektiven Vagotomie in Kombination mit Drainageoperation oder Antrektomie.
    Notes: Summary A prospective, controlled study on a standardized selection procedure of patients for the surgical treatment and on a standardized operation technique of selective vagotomy was carried out with 65 patients suffering from chronical uncomplicated or complicated duodenal ulcer. The operation technique, the aim, preparation and performance of the study, the designation of operators and investigators for the follow-up, the selection of patients for surgical treatment as well as the methods for measuring pre- and postoperatively various clinical and clinical chemical parameters are described in detail. The first follow-up was performed 6 to 12 months following surgical treatment in 60 patients. 4 patients died in the meantime, 1 patient could not be controlled because of an unknown new address. The operative mortality was 0%, intraoperative and postoperative complications were observed in 2 and 15% of the patients, whereas recurrent ulcers were found in 2 cases. The overall assessment of the clinical condition according to a modified classification of Visick was good in 85% and satisfactory in 93% of the patients. Mild diarrhoea was observed in 8%, severe diarrhoea in none and mild dumping in 30% of the patients. Positive insulin tests according to the criteria of Hollander were observed in 27% of the cases, but only in 7% were there early positive tests according to Ross and Kay. Depending on the drainage procedure, the basal secretion was reduced by 83–98%, the pentagastrin stimulated maximum secretion by 51–95%. This prospective controlled study was a preliminary investigation completed by another trial, in which two operative techniques for the treatment of chronical duodenal ulcer will be compared. The early results of our study, however, are in favour of the concept of an individually adapted treatment with selective vagotomy in duodenal ulcer.
