    Notes: Abstract  Interleukin-6 (IL-6) has been shown to be an inducer of the acute-phase response (APR) and to be involved in the pathogenesis of several disease states, including graft-versus-host disease (GvHD) following allogeneic bone marrow transplantation (BMT). As blood cells of the monocyte lineage are known to be major producers of this cytokine, we wondered whether extreme peripheral leukopenia following total ablation of hematopoiesis could compromise IL-6 production during the first days after allogeneic or autologous BMT. In the absence of detectable circulating leukocytes we measured elevated IL-6 levels in six children having fever (≥38°  C) of presumed infectious origin with an average of 74±60 units/ml (range 19–309 units/ml). IL-6 levels in febrile children having a normal hematopoiesis (118±254 units/ml, range 17–1213 units/ml) were not significantly higher than those found in the febrile BMT group (p〉0.05). Moreover, there was a clear association between elevated IL-6 levels and the presence of fever. C-reactive protein (CRP) was also elevated (≥1 mg/dl), whereas tumor-necrosis factor alpha (TNF) was undetectable (〈1 pg/ml). Two transplanted patients without fever during the period of total aplasia had neither detectable CRP nor IL-6, thus demonstrating that the transplant procedure itself does not induce an APR. Our data obtained during maximal leukopenia following BMT show that a functional hematopoietic system is not necessary for regular production of IL-6, which is associated with fever. Cells of nonhematopoietic origin may contribute to this production.

    Determination of chemical-shift tensor orientations in methylene groups by separated-local-field NMR (1993)

    Notes: The 13C chemical-shift tensor orientations in the OCH2CH2O moieties of poly(ethylene oxide) (PEO) and poly(ethylene terephthalate) (PET) were determined by means of 1H—13C separated-local-field NMR spectroscopy, and the literature values for the shift tensors in polyethylene (PE) and polyoxymethylene (POM) were improved. An angular resolution of ± 4° was attained on standard equipment with 90° pulse lengths exceeding 4 μs. Relatively high uniformity of the methylene tensor orientations, complying with local molecular symmetry, was found.

    Description / Table of Contents: The Oxopalladate Na2Pd3O4Hithertoo unknown Na2Pd3O4 was prepared. The black rod-shaped single crystals are orthorhombic, a = 3.043, b = 5.446, c = 13.175 Å, drö = 6.50 g · cm-3, dpyk = 6.43 g · cm-3, D252h-I mmm. For parameters see text.There are Pd3O4 double-layers normal to [001], which are connected with eachother by Na in a trigonal prismatic coordination. The MADELUNG part of lattice energy (MAPLE) is calculated for Na2Pd3O4 and compared with those of the binary oxids. MAPLE for a hypo-thetical form of Pd3O4 is discussed in comparison to the “isolated” double-layer Pd3O4.
