    Notes: Summary In patients suffering from ankylosing spondylitis (AS) HLA-B27 determination by means of the microlymphocytotoxicity test (MLCT) sometimes gives equivocal or false-negative results even though it has been performed with meticulous care. These failures of the test did not arise when the isolated mononuclear cells (MNC) were incubated in lymphocyte culture medium at 37°C under sterile conditions for 24h. To objectify these observations two methods of HLA class I typing were implemented before and after incubation of the test MNC in culture medium: a bioluminescence method based on the loss of adenosine triphosphate (ATP) in lysed cells in a modification of the usual MLCT and a flow cytometric (FC) test using direct immunofluorescence with an anti-HLA-B27 monoclonal antibody (MAB). In this study 50 patients with AS and 12 healthy volunteers were typed by the usual MLCT according to the NIH standard method and with both of the quantitative methods. In most of the AS patients the discrimination between positive and negative typing results became more distinct after 24 h incubation in culture medium. In the entire group of AS patients tested three false-negative typing results were prevented by this method. Although the MAB against HLA-B27 is cross-reactive with HLA-B7 and HLA-B22, errors in the FC analysis could be avoided by calibration of the flow cytometer with standard calibration beads. Possible explanations for masking of the HLA-B27 in AS patients are discussed.

    Description / Table of Contents: Zusammenfassung Minerale der Platingruppe wurden im Zuge von Goldgewinnung im Alluvium der Durance in der Nähe von Peyrolles (Bouches-du-Rhône) entdeckt. Die PGM Körner (durchschnittliche Korngröße 130μm) sind flach gepreßt (durchschnittliche Dicke 64μm). Die PGM Konzentrate bestehen vorwiegend aus (Pt, Fe) Legierungen (92%); (Os, Ir, Ru) Legierungen (3,5%), sowie gediegen Gold und (Au, Cu, Ag) Legierungen (4,5%). Folgende Minerale wurden beobachtet: Isoferro-Platin, Fe-Platin, gediegen Osmium, gediegen Iridium, Iridosmium, Rutheniridosmium, Osmiridium, Ru-Osmium, Os-Ruthenium, Cuprorhodsit, Guanglinit, Shandit, Tetrauricuprit, gediegen Gold, Bornit, HeazIewoodit, (Pt, Pd)2 Cu3, Pt(Cu, Au), (Ni, Pt)Sn, (Cu, Fe), (Pd, Rh, Pt)2+xS2, (Pt, Pd)4+xCu2As1−x. Isoferro-Platin enthält zahlreiche Einschlüsse von Legierungen, Sulfiden, Arseniden, Pd-Telluriden und teilweise devitrifzierte Silikatglaströpfchen. Die meisten nichtsili katischen Einschlüsse sind ebenfalls tröpfchenförmig. Dies weist darauf hin, daß sie in flüssigem Zustand eingeschlossen wurden. Cuprorhodsitkristalle (bis zu 20μm) sind gemeinsam mit Bornit in Pt3 Fe einge schlossen. Selten sind Pd- und Cu-Sulfide, sowie Pd-Telluride mit diesen vergesellschaftet. Bei den komplexen tröpfehenförmigen Arsenideinschlüssen im Isoferro-Platin handelt es sich um Pt-führenden Guanglinit und (Pt, Pd)4+xCu2 As1−x. Gediegen Iridium zeigt Entmischung von Ir-führendem Isoferro-Platin und (Pt, Pd)2Cu3. Stellenweise wurden Konzentrationen von Sn (bis zu 3%) in den (Au, Cu) Legierungen beobachtet. Shandit und (Ni, Pt) Sn Einschlüsse kommen in (Au, Cu, Ag) Legierungen vor. Silikatische Glaseinschlüsse sind TiO2-arm und manchmal K-reich (im Shoshonitfeld liegend). Auf Grund der mineralogischen und chemischen Eigenheiten der untersuchten PGM Konzentrate ist eine Intrusion des Alaska-Typs als primäre Quelle sehr wahrscheinlich.
    Notes: Summary Platinum-group minerals were discovered, during gold recovery, in the Durance river alluvium, near Peyrolles (Bouches-du-Rhône). The PGM grains (average size 130 microns) are strongly flattened (average thickness 64 microns). The PGM concentrate consists primarily of (Pt, Fe) alloys (92%), (Os, Ir, Ru) alloys (3.5%), and native gold and (Au, Cu, Ag) alloys (4.5%). The following minerals were observed: isoferroplatinum, ferroan platinum, native osmium, native iridium, iridosmine, rutheniridosmine, osmiridium, ruthenian osmium, osmian ruthenium, cuprorhodsite, guanglinite, shandite, tetrauricupride, native gold, bornite, heazlewoodite, (Pt, Pd)2Cu3, Pt(Cu, Au), (Ni, Pt)Sn, (Cu, Fe)1−x (Pd, Rh, Pt)2+xS2, (Pt, Pd)4−xCu2As1−x. Isoferroplatinum contains numerous inclusions of alloys, sulphides, arsenides, Pd-tellurides, and partly devitrified silicate glass droplets. Most of the non-silicate inclusions also exhibit a drop-like shape indicating their original entrapment in a liquid state. Cuprorhodsite crystals (up to 20 microns) are associated with bornite included in Pt3Fe. Rarely, Pd- and Cu-sulphides, and Pd-tellurides appear in this association. Complex droplet-like arsenide inclusions in isoferroplatinum are composed of Pt bearing guanglinite and (Pt,Pd)4+xCu2As1−x. Native iridium shows exsolutions of Ir-bearing isoferroplatinum and (Pt,Pd)2Cu3. In places, concentrations of Sn (up to 3 wt.%) were observed in (Au, Cu) alloys. Shandite and (Ni, Pt)Sn inclusions occur in (Au, Cu, Ag) alloys. Silicate-glass inclusions are TiO2-poor and occasionally K-rich (plotting in the shoshonitic field). Taking into account mineralogical and chemical pecularities of the PGM association occurring in the studied concentrate, it seems highly probable that its primary source should be an Alaskan-type intrusion.

    Notes: Summary The implications of apolipoproteins A-I and A-II for the prognosis of 178 non-diabetic men after acute myocardial infarction were studied. During a mean follow-up period of 4 years, one or more “coronary events” (nonfatal myocardial infarction, fatal coronary heart disease, coronary artery bypass graft surgery, deterioration of exercise ECG) were recorded in 37 patients. Serum levels of apolipoproteins A-I and A-II did not discriminate between patients with and without coronary events. This applied to the entire sample as much as to subgroups defined by presence or absence of interventions (coronary artery bypass graft surgery, long-term therapy with beta-blockers or lipid-lowering drugs). We conclude that coronary events in the first years after myocardial infarction cannot be predicted by apolipoprotein A-I or A-II levels.

    Notes: Abstract A κ light-chain myeloma was diagnosed as the underlying disease in a 52-year-old woman with acute oliguric renal failure. The patient was erroneously treated with high-dose intravenous melphalan (60 mg/m2). Because of this overdose treatment with granulocyte colony-stimulating factor was initiated, but pronounced absolute leukopenia (white blood cell count 〈 0.5 × 109/l) developed and lasted for 13 days. Following melphalan treatment a continuous increase in urine volume was accompanied by a decrease of serum creatinine and blood urea nitrogen. Within 10 days after the administration of melphalan the patient no longer required hemodialysis. We conclude that high-dose chemotherapy in combination with hematopoietic growth factors should be considered in individual cases with newly diagnosed light-chain nephropathy.
