    Description / Table of Contents: Zusammenfassung Wir untersuchten das Intelligenzverhalten während des Durchgangs-Syndroms (H. H. Wieck). Dazu wurden der von F. Böcker entwickelte Syndrom-Test und der von D. Wechsler beschriebene Intelligenztest in seiner deutschen Bearbeitung (Hawie) eingesetzt. Die statistische Bearbeitung des Materials ergab überindividuelle Charakteristica der gestörten Intelligenzfunktionen. Der zu psychomelrischen Zwecken konzipierte Hawie läßt sich bei nur geringfügiger Modifizierung der Methode auch als psychopathometrischer Test durchführen. Seine Ergebnisse müssen in quantitativer wie in qualitativer Hinsicht ausgewertet werden. Sie bieten dann wertvolle Hinweise auf das geistig-seelische Zustandsbild des Kranken. Die Punkteskalen von Syndrom-Test und Hawie sind qualitativ nicht ganz kongruent; sie divergieren in Richtung auf die schwereren Syndromstandien. Die Intelligenzstörungen werden mit zunehmender Funktionspsychose zunächst stärker, sind also scheinbar progredient. Sie bleiben aber rückbildungsfähig. Der Verlust an quantitativ meßbarer Intelligenzleistung wird mit der vorgenannten Einschränkung im Verlauf des reversiblen Syndroms gleichmäßig und parallel der übrigen Symptomatik kleiner. Gleiches gilt für die Teilbereiche verbaler und praktischer Intelligenz. Allerdings verhalten sich die Funktionsgruppen unterschiedlich während leichter und schwerer Psychoseprägung. Störungen erscheinen bei der verbalen später als bei der nichtverbalen Intelligenz. Ein verbales Leistungsminimum wird dagegen eher erreicht. Stark differenziert ist die Entwicklung umgrenzter intellektueller Prozesse in Form der Subtests gegenüber verschiedenen Syndromstadien. Mit zunehmender Psychose fällt die Einheit des intellektuellen Leistungsniveaus auseinander, die dem General-Faktor der Intelligenz nach C. Spearman entspricht. Die verschiedenen faktoriellen Entitäten geben dem Angriff funktionspsychotischer Störungen unterschiedlich nach.
    Notes: Summary In order to explore intelligence behaviour in the course of “Durchgangs-Syndrom” (H. H. Wieck), 30 patients were examined using the “Syndrom-Test” of F. Böcker and the German revision of the Wechsler Bellevue intelligence scale (Hawie). The statistical evaluation showed unusual characteristics of deterioration of intelligence. The Wechsler Bellevue intelligence scale (German revision Hawie) can by slight modifications easily be adapted for psychopathometric inquiry. The results are to be evaluated qualitatively as well as quantitatively, thus revealing valuable information about the actual mental state. The scales of “Syndrom-Test” and “Hawie” diverge towards severe grades of “Durchgangs-Syndrom”. Deterioration of intelligence seems to progress with increasing “Function-Psychosis” (H. H. Wieck) and vice-versa. IQ as well as certain verbal and nonverbal functions of intelligence are reduced parallel to all other symptoms of “Durchgangs-Syndrom”. Behavior of various mental function groups differs in light and severe grades of psychosis. Verbal intelligence efficiency is affected more and earlier than non-verbal intelligence. Wide differences result in the subtests of “Hawie” in the course of “Durchgangs-Syndrom”. In increasing organic psychosis the entity of intellectual efficiency gets lost, i.e. g-factor of C. Spearman decreases. Special factors differ in resistance to functional disturbances of “Durchgangs-Syndrom”.

    Notes: Summary Dog experiments were performed to describe the time course of lipid peroxidation after various ischemic influences of the heart measured by formation of malondialdehyde (MDA), and the scavenger action determined by reduced glutathione (GSH) content and superoxide dismutase (SOD) activity. Experimental groups consisted of control dogs having intact hearts and dogs with acute ramus descendens anterior ligature (LAD) having ischemic areas through 15, 30, 45 minutes and 1, 2, 3, 24 hours. Heart tissue for biochemical assays was excised from both the ischemic areas and from nonischemic left ventricle. The acute ischemia caused characteristic alterations in the biochemical parameters: MDA level gradually increased with its peak value being found at the end of 3 hours ligature. GSH levels decreased moderately, whereas SOD levels reduced sharply. As incrcased MDA formation indicates breakdown of the polyunsaturated fatty acids (PUFA) in the membranes and decreaased GSH and SOD levels indicate impairment of the natural scavengering, the observed changes clearly outline the extent of disintegration of membrane structure and function.

    Notes: Summary Experiments were performed on dog hearts following coronary ligation and treatment with synthetic antioxidant of dihydroquinoline type. Experimental groups were: (i) control dogs, (ii) dogs with ligation of descendens anterior coronary branch, (iii) coronary ligated dogs with antioxidant pretreatment and (iv) dogs with coronary ligation and simultaneous antioxidant infusion therapy. The heart infarctionper se is accompanied by the disintegration of membrane polyunsaturated fatty acids expressed by increase of malondialdehyde (MDA) concentration and the impairment of natural scavenging characterized by the decrease of superoxide dismutase (SOD) and reduced glutathione (GSH) content. The oral pretreatment with antioxidant for 8 days prevented or decreased the unfavourable pathobiochemical responses. The acute infusion therapy exerted no immediate protection, nonetheless, it could decrease the severity of pathological signs.

    Notes: The Compton energy loss spectra of atomic targets exhibits usually a specific asymmetry due to the postcollisional electrostatic interaction between the remaining ion and the ejected electron. This asymmetry, or Compton defect, also exists in the scattering by molecules or solids. The first attempt to describe the Compton defect for the hydrogen molecule is proposed here. The Compton energy loss spectra depends particularly on the relative orientation of the momentum transferred by the incident particle and the molecular axis. A comparison between the respective magnitudes of Compton profiles and Compton defects was one of the aims of this article. The results emphasize the particular interest of a simultaneous interpretation of both symmetrical and antisymmetrical contributions in the study of molecular or solid-state electronic structures. © 1995 John Wiley & Sons, Inc.
