    Notes: Abstract A girl with hemihypertrophy and hamartomas, now 14 years old, had Wilms' tumor and subsequently developed adrenocortical carcinoma. The occurrence of the two tumors with the signs of an inborn defect of growth control supports the hypothesis that both tumors can be caused by the same etiologic factors, which are also teratogenic. An alternative explanation of induction of the second tumor by previous radio- and chemotherapy is discussed. Possible relationships between our case and the syndrome of Wiedemann and Beckwith are pointed out.

    Description / Table of Contents: Zusammenfassung Die Beanspruchung in Arbeit und Beruf und ihre Auswirkungen auf biochemische Größen stehen seit Jahren zur Diskussion. In vorliegender Studie sollte das Verhalten verschiedener biochemischer Parameter bei physischer Belastung geprüft werden. Wir untersuchten Blut- und Urinproben von 31 Offiziers-anwärten der Bundeswehr vor und unmittelbar im Anschluß an einen Langstrecken marsch von 25 km. Analysiert wurden das Laktat im Vollblut, Noradrenalin, Cortisol und die cyclischen Nukleotide c-AMP und c-GMP im Plasma sowie Adrenalin, Noradrenalin, Vanillinmandelsäure und die 17-Hydroxycorticosteroide im Urin. Signifikante Erhöhungen ergaben sich für die Konzentrationen der Catecholamine und der cyclischen Nukleotide nach der physischen Belastung. Keine signifikanten Abweichungen waren für die Substanzen des Glucocorticoid-Stoffwechsels festzustellen. Die einzelnen Parameter werden hinsichtlich ihrer Relevanz für die Objektivierung physischer Beanspruchung diskutiert.
    Notes: Summary The study presented was performed to evaluate the behaviour of some stress-related biochemical parameters induced by physical stress. We investigated urine and blood samples of 32 graduating officers of the German Bundeswehr before and after a long-distance march over 25 km. The concentrations of lactate in blood, noradrenaline, cortisol and the cyclic nucleotides c-AMP and c-GMP in plasma and adrenaline, noradrenaline, vanillic mandelic acid and 17-hydroxycorticosteroids in urine were determined. Significant elevations were detectable for the concentrations of catecholamines and cyclic nucleotides after the physical work-load. No significant differences were observed for the substances of the glucocorticoid metabolism. The single parameters are discussed in respect to their significance for the objectification of physical strain.

    Simultaneous determination of T, B, and mixed rosette-forming lymphocytes in human peripheral blood (1977)

    Notes: Abstract Preliminary treatment of erythrocytes in suspension with trypan blue did not affect their ability to take part in the spontaneous rosette formation test, but enabled them to be distinguished when mixed with other erythrocytes after staining with methyl green-pryronine in fixed preparations. The presence of a small subpopulation of lymphocytes binding both types of indicator particles was demonstrated by the use of a mixture of these, erythrocytes with erythrocytes sensitized by antibodies and complement.

    Suppression of delayed type hypersensitivity of mice by lead (1977)

    Notes: Summary Application of lead suppressed the delayed type hypersensitivity (DTH) of mice induced by sheep red blood cells (SRBC). Inhibition of elicitation of DTH in primary as well as in secondary response was correlated with the concentration of lead in the blood of the mice.

    Inner-shell ionization by relativistic electron impact (1979)

    Notes: Abstract K-, L andM-shell ionization cross sections have been measured for 23 elements, 12≦Z≦92, after bombardment with relativistic electrons, 15≦E 065MeV, by means of high resolution semiconductor detectors and a recently developed gas-scintillation proportional counter. For constant electron bombarding energyE 0 the ionization cross sections follow a power law dependence,σ∽Z −α, and forE 0=50MeV we deducedα =2.45±0.02 for theK shell andα=3.00 ±0.09 for theL shell. The observedZ dependence exhibits significant systematic deviations from theoretical predictions which exceed the experimental values up to 15 % at lowZ elements for theK shell and on the average about 11% for theL andM shell. The same behaviour of too low experimental values, i.e. an overestimation by the theory, is observed for the energy dependence of the cross sections for all shells. A scaling behaviour describing theZ andE 0 dependence for allK-, L andM-shell data points is observed which also predicts the experimental values by other groups at lower and higher energies correctly. The comparsion of the measuredLΒ/Lα, andLγ/Lα intensity ratios for highZ elements with the values obtained by other groups in the energy range 0.3≦E0≦1,000 MeV exhibits an increase with bombarding energy that cannot merely be explained by the energy dependence of the subshellionization cross sections for theL shell. An attempt to explain this effect with the change of the Coster-Kronig transition probability is described.

    Notes: Summary Chronic oral exposure of mice to Cd++ inhibits cell-mediated immunity of delayed type hypersensitivity induced by sheep red blood cells (SRBC). No effect was detected on humoral immune response to SRBC. Spleen cells derived from mice exposed to Cd++ showed in vitro enhanced response to T and B cell mitogens. These results demonstrate that Cd++ exposure alters the immune system of mice.

    Description / Table of Contents: Polyurethanes obtained by reacting mercapto-terminated oligobutadienes, decanedithiol and diisocyanate were investigated by electron microscopy and x-ray scattering. The dependence of the morphological structure on the content of short-chain dithiol is discussed. Heterogeneities in micro- and macroregions were observed, which are caused by crystalline regions and phase separation in chemically different blocks.
    Notes: Polyurethane auf der Basis von mercapto-terminierten Oligobutadienen, Decandithiol und Diisocyanat werden mittels Elektronenmikroskopie und Röntgenstreuung untersucht. Ihre morphologischen Besonderheiten werden in Abhängigkeit vom Gehalt an Kurzkettendithiol diskutiert. Es treten Heterogenitäten im Mikro- und Makrobereich auf, die durch kristalline Bereiche und Phasentrennung in chemisch unterschiedliche Blöcke bedingt sind.
