    Notes: Summary.  Haemophilia A is an X-linked bleeding disorder caused by mutations in the factor VIII gene. In our efforts to elucidate molecular defects in the haemophilia A patients from the Republic of Macedonia, we employed nonradioactive single-strand conformation polymorphism analysis followed by direct sequencing, for identifying point mutations in the factor VIII gene. In the present study we report the detection of three novel missense mutations: Met-19→Arg; Ala78→Pro and Cys2174→Gly, all causing haemophilia A.

    Notes: Abstract The optimum conditions for extraction of ion-associated complexes (IAC) formed from the tetrazolium salt-tetrazolium violet and Sb(V) in hydrochloric acid medium have been studied. An isotope of antimony (125Sb) was used for determination of the recovery factor (R%) and distribution ratio (DSb). The thermal behavior of the antimony complex with tetrazole violet was studied using differential thermal and thermogravimetric analysis.

    Notes: Abstract The optimum conditions for extraction of niobium(V) as a ternary ion-association complex with pyrocatechol and triphenyltetrazolium chloride(TTC) have been determined. The investigation of the composition has shown that the ratio Nb:proocatechol:TTC is 1:2:1 Kex, KD and β have been determined radiometrically, using the chemical model. The influence of foreign ions on the extraction of the ion-association complex has been studied. A method for artifical mixture and steel containing niobium has been used.

    Description / Table of Contents: Summary The optimum conditions for the antimony(V) extraction in strong hydrochloride acid medium as a ternary ion-associated complex with triphenyltetrazolium chloride have been investigated. The extraction constant has been determined with dichlorethene and chloroform (1∶1) (K ex =3.06×104). A working procedure for the determination of antimony has been developed. Interferences are only caused by iron(III), gold(III), thallium(III) and gallium. The application of the method is demonstrated by the analysis of metallic lead, which has also been carried out with two other methods (AAS and spectrophotometry with crystal violet). The new method is superior in reliability and accuracy. The relative standard deviation of the mean is ± 7.4%.
    Notes: Zusammenfassung Die optimalen Bedingungen für die Extraktion von Antimon aus stark salzsaurer Lösung als Ionenanlagerungskomplex mit Triphenyltetrazoliumchlorid wurden bestimmt. Die Extraktionskonstante bei Extraktion mit einer Dichlorethan-Chloroform-Mischung (1∶1) beträgt (K ex =3,06·104). Für die Antimonbestimmung wurde eine entsprechende Methode ausgearbeitet. Nur Fe(II), Au(III), Tl(III) und Ga(III) stören. Die Anwendung der Methode wurde an Hand der Analyse von metallischem Blei demonstriert, die zusätzlich auch nach zwei anderen Methoden (AAS und Spektralphotometrie mit Kristallviolett) durchgeführt wurde. Die neue Methode ist in bezug auf Zuverlässigkeit und Genauigkeit überlegen. Die relative Standardabweichung des Mittelwertes beträgt ± 7,4%.
