Chronic Prostatitis and Prostatodynia: Ultrasonographic Alterations of the Prostate, Bladder Neck, Seminal Vesicles and Periprostatic Venous Plexus
1988
Transrectal ultrasonography was performed in 121 patients with the chronic prostatitis syndrome (CPS), and in 20 patients with urological pathology not involving the prostate gland. The ultrasonographic aspects of the seminal vesicles (SV) in normal subjects and in patients with the CPS are described. In the latter group, characteristic ultrasonographic patterns can often be obtained, even in patients affected by prostatodynia, in whom all the other clinical and laboratory findings were absent. They consisted of: (a) dyshomogeneous echo-structure of the prostate; (b) constant dilatation of the periprostatic venous plexus, greater than 150 mm2; (c) dilated, elongated SV, with thickening of t…
Magnetresonanztomographie in der Diagnostik des Kollumkarzinoms. Computertomographische und histologische Korrelation
1988
The value of magnetic resonance tomography in the diagnosis of carcinoma of the cervix was studied in a prospective series of 20 patients. The results were compared with those of computed tomography and with the clinical findings. The diagnosis depended on the postoperative histology. Gynaecological examination proved superior to imaging methods in determining the extent of local tumour spread. Tumour involvement of the regional lymphatic system was better demonstrated by MRT than by CT. Exact staging proved inadequate with both these methods and the new imaging methods have not produced any changes in operative planning or technique.

Therapie des metastasierten Prostatakarzinoms — 1 Jahr nach Würzburg
1988
An mittlerweile mehr als 150 Patienten mit bisher unbehandeltem Prostatakarzinom konnten wir in den vergangenen 6 Jahren den Kastrationseffekt von pernasal appliziertem Buserelin belegen [1, 2]. Partielle oder komplette Remissionen (objektiviert nach den Kriterien der National Prostatic Cancer Treatment Group oder der EORTC) liegen nach 6 Monaten je nach zugrunde gelegten Ansprechkriterien bei gut 50%, die Progressionsrate bei etwa 20%. Diese Daten konnten mittlerweile von anderen Autoren auch mit anderen LHRH-Analoga als Monotherapie reproduziert werden.
Neue Entwicklungen und Tendenzen in der Pharmakotherapie chronisch entzündlicher Darmerkrankungen
1988
Das Ziel, die chronisch entzundliche Darmerkrankungen durch Medikamente zu heilen, wurde bislang nicht erreicht. Es hat dabei nicht an Versuchen und Untersuchungen gefehlt. In Anbetracht der nach wie vor ungeklarten Pathogenese ist man verschiedenen Spuren gefolgt, aber keine fuhrte zum Ziel.
Ein Neuer Kombinationstest und Dessen Erweiterung zur Identifikation von Alternativen

Hypertriglyceridemia and Omega-3 Fatty Acids
1988
Recent studies by Bang and Dyerberg (1) have stimulated interest in the metabolism of omega-3 fatty acids and have suggested a link between the ingestion of these fatty acids in a diet and the low death rate from athersclerotic disease in Eskimos. In Japan, where fish consumption has traditionally been high, a concommitant shift in tissue lipid consumption favouring omega-3 polyunsaturated fatty acids has been interpreted as causative of a relatively low incidence of cardiovascular disease (1). When analyzing Eskimo food consumption, it became clear that the consumption of omega-3 PUFA is much higher besides a 50% reduction of saturated fat and a relatively high content of monounsaturated f…

Buckling of Elastic Beam Under Unilateral Constraint
1988
ABSTRACT A criterion is proposed to calculate the critical load of a continuous beam under unilateral constraint. The beam is assumed to be built in at the ends and to rest on equally spaced elastic supports, that have equal stiffness. The problem is solved by determining the length of the half-wave of the buckled shape, the number of supports involved, and their position with respect to the end of the half-wave. The analysis model thus defined is determined in relation to the geometry of the beam and to the ratio between the stiffness of the supports and the shearing stiffness of the generic span. It is shown that there exists a limiting value of this ratio, below which the critical load i…
G-Spaces and Kaluza-Klein Theory
1988
G-spaces are present whenever symmetries are relevant in physics. After a short introduction to this subject, spontaneous symmetry breaking in elementary particle physics is considered from this point of view. Kaluza-Klein theory is discussed in a purely geometrical formulation. Some results in connection with the geometrical compactification scheme are presented.

Incidence of lineage promiscuity in acute myeloblastic leukemia: Diagnostic implications of immunoglobulin and T-cell receptor gene rearrangement ana…
1988
Abstract Sixty-nine blood or bone marrow samples from both children and adults with acute myeloblastic leukemia (AML) were investigated to elucidate the frequency of immunoglobulin (IG) and T-cell receptor (TCR)-gene rearrangements. Non-germline configuration for the IG heavy chain (h) gene was detected in the specimens of nine patients of various subtypes according to the French-American-British classification (FAB), including FAB M1, M2, M4 and M5. Rearrangement of the IG kappa chain (k) gene was present in one of these cases which simultaneously revealed a rearranged TCR-beta (b) chain gene. In another two AML samples we found TCR-b gene rearrangements, in one case in combination with an…

Structure and superconducting properties of YBa2(Cu1−x Fex)3O7
1988
Fe-substituted Y-Ba-Cu superconducting oxide compounds were investigated by dc-magnetic susceptibility measurements, powder X-ray diffraction and Mdssbauer spectroscopy. Fe substitution caused a structural transformation from orthorhombic to tetragonal. Up to 4 at% Fe Tc was almost unaffected. It was found that superconductivity in Cu oxides does not depend on orthorhombic crystal symmetry.
Computertomographie und Kernspintomographie bei Prozessen im Bereich der Schädelbasis und der Schädelkalotte
1988
Der Nutzen der Computertomographie bei der Untersuchung der Schadelbasis, insbesondere die zahlreichen diagnostischen Aspekte einschlieslich der Moglichkeit der Planung einer operativen oder strahlentherapeutischen Behandlung sind von zahlreichen Autoren schon kurz nach Einfuhrung der CT herausgestellt worden (Liliequist u. Forsell 1976; Bradac et al. 1977a, b, 1977, 1978a, b; Hammerschlag et al. 1977; Caille et al. 1977; Lohkamp et al. 1977; Huk u. Schiefer 1978; Becker et al. 1978; Weinstein et al. 1978). Aussagekraft und Grenzen der CT- und Kernspintomographie (KST) bei der Diagnose von Erkrankungen im Bereich der knochernen Schadelbasis und der Schadelkalotte werden in diesem Kapitel zu…
A microcosm study on the respiration and weight loss in birch litter and raw humus as influenced by soil fauna
1988
The effect of diverse soil fauna (Collembola, Acari, Enchytraeidae, Nematoda) on decomposition of dead organic matter was studied in microcosms containing (1) birch leaf litter, (2) raw humus of coniferous forest and (3) litter on humus. Total respiration (CO2 evolution) was monitored weekly, and mass loss, length of fungal hyphae (total and metabolically active) and survival of animal populations were checked at the end of weeks 12 and 21–22 from the start of experiment. Animal populations established themselves well during the incubation. At the end of the experiment some replicates containing litter had microarthropod densities of up to 500 specimens per microcosm, corresponding to a fie…

Technologiebewertung in der Intensivmedizin
1988
Keinem Bereich der modernen Medizin ist die sogenannte Ubertechnisierung so zum Vorwurf gemacht worden, wie der Intensivmedizin. Jedoch resultierte aus der Einfuhrung der automatischen EKG-Uberwachung und Blutdruckmessung eine Erhohung der Prazision, eine zuverlassige Aufzeichnung elementarer Vitalwerte und eine Entlastung qualifizierten Personals. Invasive und nicht-invasive Messungen ventrikularer Fullungsdrucke hingegen sind ein Paradebeispiel dafur, wie technologische Orientierung in der Intensivmedizin mangels eindeutiger Aussagen herkommlicher Techniken neue Technologien kreieren. Unter therapeutisch nutzbarer Technik in der Intensivmedizin stehen Infusionstechnologie und Beatmungstec…
Dramatic conversation: An exploratory application of Burton's discourse model
1988
The British sociolinguists Sinclair and Coulthard have generated a systematic approach to the analysis of natural conversation using classroom discourse. Burton has articulated an innovative development of this model that she claims is applicable to a broad range of spoken discourse. She focuses on the language of dramatic plays. Her model is explained, and in an attempt to assess its viability, an application to a brief exchange in a Tennessee Williams play and its Italian translation is proposed. Interesting differences between the interactive structures of the two texts are revealed, indicating that Burton's model may be fruitful for the analysis of fictional dialogue. However, theatre t…

L'Hipòlit d'Eurípides i la capacitat d'introspecció lingüística dels atenesos
1988
L'objectiu d'aquesta breu nota no excedeix la simple voluntat de mostrar com els mateixos autors grecs posseien una idea clarissima del valor lingüístic de les seves obres, la qual cosa no sempre entenem nosaltres, des de la perspectiva que ens és prbpia. Fins i tot tenim, massa sovint, la pretensió d'esmenar els textos transmesos, a despit de la garantia d'aquesta transmissió, exactament com si tinguéssim la certitud que tal autor o tal altre mai no foren capasos d'escriure el que ens n'ha arribat. Nogensmenys, la familiaritat generada per la lectura fidel d'un text qualsevol, tot i la prevenció que ha de presidir l'exercici de la tasca filolbgica, permet de copsar l'elevadissim grau de co…

Morphological studies in canine (Dalmatian) neuronal ceroid-lipofuscinosis.
1988
Dalmatian dogs may develop a neuronal or generalized ceroid-lipofuscinosis (NCL) which strongly resembles that seen in English setters, especially as to the ultrastructural changes and ubiquity of the stored lipopigments and the retinal pathology, while differing clinically from the disorder of English setters in that the disease has a longer course of up to 5 or 6 yr. Clinical onset is at about age 6 months; however, an unequivocal morphological diagnosis is possible between the 4th and 5th month of life in biopsied skin. Detailed data of additional investigations are in progress and are awaiting later publication. Thus, NCL in the Dalmatian dog, though not yet as thoroughly investigated a…
Active vanadate-sensitive H+ translocation in corn roots membrane vesicles and proteoliposomes
1988
Abstract A member fraction from corn roots which contains a vanadate-sensitive ATPase activity has been prepared. The specific activity at 38°C is between 3 and mol 12 μmol · min −1 · mg −1 , depending on the age of roots. Addition of ATP promotes a very rapid quenching of the fluorescence of 9-amino-6-chloro-3-methoxy-acridin (ACMA). Proton pumping exhibits a delayed sensitivity to vanadate but is strongly and instantaneously inhibited by the new inhibitor SW 26. Both proton pumping, measured by the initial quenching rate, and ATP hydrolysis show maximum activities at ATP concentrations in the millimolar range, but the apparent K m -value for hydrolysis is higher than that observed for pro…
