    Notes: Abstract In the present study we investigated the long-term effect of intravenous pulse cyclophosphamide (CY) on lymphocyte surface antigens in systemic lupus erythematosus (SLE) patients. Blood samples derived from 17 lupus erythematosus patients were analysed using two- and three-colour flow cytometry. During the CY therapy, the total number of T lymphocytes (CD3+) was reduced by 31.4%, B lymphocytes (CD19+) by 67.4% and NK cells (CD16+) by 27.4%. Six months after the end of the CY regimen, these values recovered to entry levels. At the onset of the study we observed increased percentages of CD3+ CD25+, CD3+ CD4– CD8–, CD4+ CD29+, CD19+ and CD19+ CD5+ cells. The CY treatment regimen decreased the CD3+ CD25+, CD3+ CD4– CD8–, CD19+ and CD19+ CD5+ cells, but increased the CD3+ CD8+ subpopulation. Taken together, a deficiency of CD8+ T cells associated with CD4+ CD29+ predominance may imply an immune regulatory imbalance leading to abnormal CD4+ cell activation and in consequence to autoimmunity. Depletion of CD19+ cells combined with an enlargement of CD8 cells as a result of CY therapy may reduce the enhanced immune response in SLE patients.

    Notes: Abstract Surgical excision is considered the treatment of choice for cystic hygromas (CH). However, radical surgery may result in serious complications, and nerve palsy due to dissection occurs in 12% – 33% of cases in most series. Resection is especially difficult and sometimes impossible if the lesion involves the floor of the mouth, tongue, and larynx. Different alternative treatment modalities have been advocated in cases of life-threatening, unresectable CHs, however, most of them are associated with severe side effects and doubtful effectiveness. Two children with inoperable CHs of the head and neck are presented. Since intralesional injection of sclerosing agents was unsuccessful, they were treated with IV cyclophosphamide. In both patients tumor size markedly regressed and vital functions stabilized, even though only partial remission was obtained. Cyclophosphamide seems to be a useful and well-tolerated treatment alternative in children with unresectable life-threatening CHs.

    Notes: 1. Zwischen 300 und 948° entsteht bei der Chlorierung von Rhodium nur Rhodiumtrichlorid, zwischen 948-968° bilden sich Gemische der beiden neuen Chloride: 2- und 1-Chlorid, die sich durch schlämmen zerlegen lassen.

    Description / Table of Contents: A4N2O5 (A = Na, K) Novel Alkali Metal Oxide Nitrites, and a Comment on the System K3NO3/K3OBrK4N2O5 and Na4N2O5 have been prepared for the first time: the respective alkali metal nitrites and -oxides in molar ratios 2 : 1 have been reacted in the solid state. Their crystal structure (for crystallographic data see „Inhaltsübersicht“) derive from the anti-K2NiF4 type of structure. Na4N2O5 undergoes two phase transitions (at -15°C and -60°C) upon cooling.The behavior of solid solutions in the system K3NO3/K3OBr at cooling gives support for the phase transition being driven by the OK3-framework, where as in Na3NO3 order-disorder transitions of the NO2- group seem to induce the phase transitions.
    Notes: K4N2O5 und Na4N2O5 wurden erstmals erhalten durch Festkörperreaktionen der entsprechenden Alkalimetallnitrite und Alkalimetalloxide im Mol-Verhältnis 2 : 1. Die Kristallstrukturen (K4N2O5: I4/m; a = 520,4(2), c = 1592,6(8) pm; 150 Reflexe; R = 0,035. Na4N2O5: Pulverdaten; a = 457,2(1), 903,5(1), 1495,3(3) pm; orthorhombisch) leiten sich von dem anti- K2NiF4-Typ ab. Na4N2O5 durchläuft zwei Phasentransformationen bei -15°C und -60°C.Das Tieftemperaturverhalten der Mischkristalle im quasibinären System K3NO3/K3OBr (vollständige Mischbarkeit) stützt die Auffassung, daß die Phasenumwandlung durch das OK3-Gerüst getrieben wird, während dafür in Na3NO3 Ordnungs-Unordnungsübergänge der NO2--Anionen verantwortlich sind.

    Description / Table of Contents: On the Quasi-Binary Systems NaNO2/Na2O and NaCN/Na2O. Phase Diagrams and Sodium Ion Conductivity of Na3O(NO2) and Na3O(CN)Measurements of the electrical conductivities of Na3O(NO2) and Na3O(CN) show sharp increases in conductivity at temperatures between 200° and 250°C, According to the phase diagrams of the quasi-binary systems NaNO2/Na2O and NaCN/Na2O this is not an effect established by fusion. It seems to be a consequence of a “melting” of the sodium sublattice or the rotational disorder of complex anions.
    Notes: Messung der elektrischen Leitfähigkeit von Na3O(NO2) und Na3O(CN) zeigen, daß beide Verbindungen bei Temperaturen zwischen 200° und 250°C eine sprunghafte Zunahme der Natrium-Ionenleitfähigkeit aufweisen. Diese Effekte beruhen nicht auf Schmelzprozessen, wie die Phasendiagramme der entsprechenden pseudo-binären Systeme NaNO2/Na2O und NaCN/Na2O belegen, sondern sind auf Rotationsdiffusion der komplexen Anionen bzw. ein Teilschmelzen der Kationenteilstruktur zurückzuführen.
