    Cellular and secreted tumor plasminogen activator: The effects of NaCl (1986)

    Notes: Summary Plasminogen activator, secreted by metastatic tumor cells, was strongly inhibited in buffer or tissue culture medium containing physiological concentrations of NaCl. Intact cells, however, expressed strong activity under similar conditions. Thus, if plasminogen activator is involved in invasion and metastasis, the cellular activity, acting as an ectoenzyme, may be more important than secreted enzyme under physiological conditions.

    Notes: Abstract Eighty-six children (44 males, 42 females) were identified as having non-tuberculous mycobacterial lymphadenitis. The diagnostic criteria were either culture of the organism from the affected lymph node (n=68), or, when culture was negative, a positive skin test with non-tuberculous mycobacterial antigens and negative skin test responses to tuberculin purified protein derivative (PPD) in association with typical histological features (n=18). All children had histopathological findings of granulomatous inflammation with caseation and/or acid-fast bacilli. Eighty-two percent of the children were under 5 years of age at presentation and 30% were less than 2 years old. Most (79%) were city dwellers. Lymph node enlargement had been present for less than 6 months in almost all children (97.5%) and was almost exclusively in the face and neck region (97%). Disease was confined to the involved lymph nodes in 56% but had extended beyond the confines of the infected node to form a collar stud abscess in 38% and 6% presented with a skin sinus. Extranodal extension did not show any statistically significant association with the duration of lymphadenopathy. The duration of lymphadenopathy had been greater in those children in whom an organism was not isolated on culture resected tissue χ2, P〈0.01). All children were treated surgically, and recurrence occurred in five patients. This study describes the clinical and demographic characteristics of non-tuberculous mycobacterial lymphadenopathy in children in a population in which tuberculous adenitis is rare. Recognition of these features may allow earlier diagnosis and appropriate surgical therapy.

    Reaktionen von (η2-Ethen)bis(triphenylphosphan)-platin(0) mit dimerem Hexafluorthioaceton Darstellung und Struktur von Platinacyclopentan- und -cyclopropanderivaten (1986)

    Description / Table of Contents: Reactions of (η2-Ethene)bis(triphenylphosphane)platinum(0) with Dimeric Hexafluorothioacetone. Preparation and Structure of Platina Cyclopentane and Cyclopropane DerivativesThe five-membered (CS)2Pt ring 1 was obtained by the reaction of 2, 2, 4, 4-tetrakis(trifluoromethyl)-1,3-dithietane and (η2-ethene)bis(triphenylphosphane)platinum(0) at low temperatures. 1 is converted at its melting point to the three-membered CSPt ring derivative 2, with elimination of one molecule of hexafluorothioacetone. 2 is also formed directly when the reaction is conducted at temperatures above +30°C. 2 was characterized by an X-ray Structural analysis.
    Notes: Der fünfgliedrige (CS)2Pt-Cyclus 1 kann aus 2, 2, 4, 4-Tetrakis(trifluormethyl)-1,3-dithietan und (η2-Ethen)bis(triphenylphosphan)-platin(0) bei tiefer Temperatur erhalten werden. 1 wandelt sich an seinem Schmelzpunkt unter Abspaltung eines Moleküls Hexafluorthioaceton in den um zwei Ringglieder reduzierten CSPt-Ring 2 um, der auch auf direktem Wege durch Umsetzen des Dithietans bei Temperaturen oberhalb von +30° zugänglich ist. 2 konnte erstmals durch eine Kristallstrukturbestimmung charakterisiert werden.
