    Notes: Abstract We examined four patients with fluorosis, presenting with compressive myelopathy, by MRI, using spin-echo and fast low-angle shot sequences. Cord compression due to ossification of the posterior longitudinal ligament (PLL) and ligamentum flavum (LF) was demonstrated in one and ossification of only the LF in one. Marrow signal was observed in the PLL and LF in all the patients on all pulse sequences. In patients with compressive myelopathy secondary to ossification of PLL and/or LF, fluorosis should be considered as a possible cuase, especially in endemic regions.

    Notes: Abstract The majority of patients with acute myeloid leukemia (AML) are elderly, and their response to chemotherapy is poorer than that of younger patients. The combination of mitoxantrone (MTN) and cytosine arabinoside (Ara-C) is a possible alternative to an anthracycline/Ara-C combination for the treatment of AML in these patients. Of 52 older patients (〉 59 years) referred over a 3.5-year period, 33 patients (age range 60–78 years, median 67 years) received MTN and Ara-C as therapy for newly diagnosed AML. MTN was administered at a dose of 12 mg/m2/day, intravenously, for 3 days (23 patients), or 10 mg/m2/day for 5 days (10 patients), and Ara-C at a dose of 100 mg/m2 twice daily, intravenously, for 7 days. Complete remission (CR) was achieved in 16/33 patients (48%). The median remission duration was 6 months (range 1–37 months). The median survival was 14 months for those who achieved CR compared with 9 months for those with resistant disease. Two patients remain in first CR after 13 and 37 months, but three patients died whilst receiving consolidation therapy. In selected elderly patients with AML, the combination of MTN and Ara-C provides an acceptable alternative to an anthracycline/ Ara-C regimen, with a higher CR rate than historical controls. However, the CR rate and remission duration remain low compared with those of younger patients, supporting the need to investigate new approaches to treatment in this population.

    Description / Table of Contents: Die Stabilitätskonstanten der Komplexe von Mn++, Fe++, Co++, Ni++, Cu++, Zn++, Cd++ und UO++2 mit 5, 7-Dichlor-, 5, 7-Dibrom- und 5, 7-Dinitro-8-hydroxychinolin und der entsprechenden N-Oxide sind in Dioxan/Wasser-Gemischen (75/25) bei 35°C in Gegenwart von 0,20 m Natriumperchlorat durch Titration nach Irving und Rossotti bestimmt worden. Eine mögliche Erklärung für die beobachtete Abhängigkeit der Stabilitätskonstanten der Komplexe bei Variation des Liganden und andererseits bei Variation des Metalls wird vorgeschlagen.
    Notes: The stability constants of complexes of Mn++, Fe++, Co++, Ni++, Cu++, Zn++, Cd++ and UO++2 with 5,7-dichloro-, 5,7-dibromo- and 5,7-dinitro-8-hydroxyquinoline and their corresponding N-oxides have been determined in 75 + 25 v/v dioxan + water medium at 35°C in presence of 0.20 M sodium perchlorate by pH-titration technique as given by IRVING and Rossotti. A possible explanation for the observed orders of the stability constants of the metal complex with the different ligands, and of the complexes of a particular ligand with different metal ions is also proposed.
