    Description / Table of Contents: Zusammenfassung Der Einfluß einer induzierten Hypercalcämie auf die Serumgastrinspiegel und die Magensekretion wurde bei Normalpersonen, Patienten mit Ulcus duodeni und Patienten mit Zollinger-Ellison-Syndrom untersucht. Bei allen Patientengruppen kommt es während der Calciumgluconatinfusion zu einem signifikanten Anstieg der Serumgastrinspiegel. Patienten mit Ulcus duodeni schütten jedoch 2–3mal soviel Gastrin während einer Hypercalcämie aus wie Normal-personen, während die Gastrinausschüttung bei Patienten mit Zollinger-Ellison-Syndrom ein Vielfaches der von Ulcus duodeni-Patienten beträgt. Die integrierte Säureausschüttung während Hypercalcämie ist bei Ulcus duodeni-Patienten ca. 5fach höher als bei Kontrollpersonen. Diese Untersuchungen zeigen, daß die Calcium-induzierte Magensekretion, zumindestens teilweise, durch eine Gastrinfreisetzung hervorgerufen wird.
    Notes: Summary We studied the effect of hypercalcemia on the serum gastrin concentration and gastric secretion in normal man, duodenal ulcer patients and patients with the Zollinger-Ellison syndrome. All subjects showed a significant increase of serum gastrin concentrations during calcium infusion. Patients with duodenal ulcer showed a 2- to 3-fold higher gastrin output during hypercalcemia than normal subjects, but the gastrin output in patients with Zollinger-Ellison syndrome was much higher compared to patients with duodenal ulcer. The integrated gastric secretory response to hypercalcemia is 5-fold higher in duodenal ulcer patients compared to normal subjects. These studies show that, at least in part, the calcium-induced gastric secretion is caused by gastrin release.

    Notes: We have used pyridine and a number of related molecules to lower the workfunction of thin Ag films so as to compare the effects of various molecular properties on the photoemission process and on surface electronic modes. We find that a nitrogen lone pair electronic orbital is essential for a large threshold shift. Other molecular properties, such as dipole moment and polarizability have a very small effect. The films are rough, therefore we see strong photoyields at the energy of the surface plasma mode, 3.6 eV. There is also a peak in the photoyield at 3.85 eV, the energy of the bulk plasmon.

    Notes: We report here part of a detailed study of pulsed photoemission into pure liquid NH3. We find that scavengers and salts are not essential to the detection of photoelectrons in NH3, in contrast to previous measurements in H2O. A six order-of-magnitude range in the quantum yield has been found. Maximum yields are near 10−2 electrons per photon. As previous workers, we find a two-slope response to the yield curve which may be interpreted in terms of two thresholds. We interpret out observations in terms of photoinjection into a band of localized states lying below the conduction band of the NH3. The bottom of the conduction band in NH3 is found to be 0.95 eV below the vacuum. The band of localized states extends approximately 0.4 eV lower. Our analysis does not support either the ″4/2's″ or the ″5/2′s″ laws relating the yield to the excess energy above threshold.

    Notes: We offer a version of the Kretschmann configuration of an attenuated total reflection measurement in which there is only one rotating element. Significant simplifications in construction and operation are thereby attained.

    Notes: [Auszug] The spectrum consists of several series of lines with first order Stark shifts separated by about 5 Gc/s. Each series extends over about 2 Gc/s and is roughly divided into groups. The lower frequency groups of each series are clear cut, but beyond about the third they become more complicated and ...
