    Notes: Summary A rate on autopsy of up to 30% systemic fungal infections and difficulties in diagnosing systemic mycosis antemortem have led to the empiric use of amphotericin B in patients with hematological malignancies, prolonged fever, and neutropenia. Routine empiric antifungal treatment was initiated in our institution in 1982. Amphotericin B was given to granulocytopenic patients with hematological malignancies with (a) unremitting fever after 48–72 h of antibiotic treatment, (b) recurrent fever during antibiotic treatment, or (c) with newly detected pulmonary infiltrates, sinusitis, skin and retinal lesions suggestive of a fungal infection. With this approach the rate of systemic fungal infections decreased significantly from 10% (27 of 270 patients; 1973–1981) to 4% (6 of 153 patients; 1982–1986,P〈0.02). The reduction of systemic fungal infections was most prominent in patients with acute myelogenous leukemia, where its proportion decreased from 16% (16 of 98 patients; 1973–1981) to 4% (2 of 50 patients; 1982–1986,P〈0.023). Our data support the hypothesis that the incidence of systemic fungal infections in patients with hematological malignancies and especially in acute myelogenous leukemia can be reduced significantly by empirical treatment with amphotericin B.

    Notes: Abstract The condensation of the Y chromosome in mouse cells was studied with two repetitive DNA probes, pY353/B and M34. Both DNA probes are specific to the Y chromosome and hybridize in situ along the whole chromosome. Due to the high resolution of the in situ hybridization technique with non-radioactive labeled DNA probes it was possible to observe the degree of condensation of the Y chromosome in the interphase cell nuclei of various somatic tissues and on testes preparations. The Sertoli cells were the only cell type in which the Y chromosome was always observed to be in a highly decondensed state. The decondensation of the Y chromosome in the Sertoli cells supports the view that the genetic activity of the Y chromosome is cell autonomous and opens the way to its molecular analysis.

    Description / Table of Contents: Zusammenfassung Es wurden 42 Nierentransplantat-Empfänger wegen Harnwegsinfektionen mit Ofloxacin oral behandelt. 39 Patienten erhielten Ciclosporin A, drei Patienten Azathioprin, jeweils in Kombination mit Prednisolon zur Immunsuppression. Bei allen Patienten wurden vor, während und nach der Ofloxacin-Therapie Laborparameter routinemäßig untersucht, unter besonderer Berücksichtigung nephrotoxischer Erscheinungen bzw. möglicher Interaktionen mit der begleitenden immunsuppressiven Medikation. In der vorliegenden Studie erwies sich Ofloxacin als sicheres und effektives Antibiotikum in der Behandlung von Harnwegsinfektionen bei nierentransplantierten Patienten ohne nachweisbare Nephrotoxizität oder toxische Interferenzen mit Ciclosporin A bzw. Azathioprin.
    Notes: Summary Forty-two renal transplant recipients suffering from complicated urinary tract infection (UTI) were treated orally with ofloxacin. Patients received an immunosuppressive treatment consisting of ciclosporin A and prednisolone (n=39) or azathioprine and prednisolone (n=3). Patients were routinely controlled for laboratory parameters before, during and after ofloxacin administration with special emphasis on nephrotoxicity and interaction of ofloxacin with the concomitantly administered immunosuppressives. Results show that ofloxacin does not impair renal graft function or interact with ciclosporin A or azathioprine even under long-term administration. It is effective and safe in the treatment of UTI in the renal transplant recipient.

    Description / Table of Contents: Potassium Sodium Sulphide, KNaS: A New Inter Alkali Metal SulphideHitherto unknown KNaS has been prepared by annealing a mixture of Na2S and K2S. X-ray single crystal structure determination has been performed. The hygroscopic, colorless compound crystallizes in the orthorhombic space group Pnma (Z = 4) with the lattice parameters a = 770.3(1), b = 460.4(1), c = 829.3(1) pm. Refining of the structure lead to a least squares residue of 0.035. KNaS is isostructural to PbCl2. The S2- are hexagonally closest-packed. Sulphur tetrahedra occupied by sodium ions share cis-located edges forming chains interconnected by vertices. The K+ are situated out of the center of octahedral sites diminishing the repulsion of the distinct metal ions. The new description of the PbCl2-type structure is corroborated by group-subgroup analysis.
    Notes: Bislang unbekanntes KNaS wurde durch Tempern eines Gemenges von Na2S und K2S dargestellt. Das farblose, hygroskopische Sulfid kristallisiert in der Raumgruppe Pnma (Z = 4) mit a = 770,3(1) pm, b = 460,4(1) pm und c = 829,3(1) pm. Die Struktur wurde über Röntgenbeugung an Einkristallen bestimmt (R = 0,035). KNaS ist antiisotyp mit PbCl2. Die Anionen S2- bilden eine verzerrt hexagonal dichteste Kugelpackung. NaS4-Tetraeder sind über cisständige Kanten zu Ketten verknüpft, die untereinander über Spitzen verbunden sind. Die K+ befinden sich in den Oktaederlücken und sind zur Verminderung der elektrostatischen Abstoßung von den Na+ aus deren Zentren gerückt. Die Gruppe-Untergruppe-Analyse unterstützt die neuartige Beschreibung der PbCl2-Struktur.
