    Notes: Abstract The detection of molecular defects of hemoglobin variants using mutagenically separated polymerase chain reaction (MS-PCR) was applied in this study. Using different lengths of allele-specific mutagenic primers, normal and mutant alleles of hemoglobin genes were amplified in the same reaction tube. Subsequent gel electrophoresis showed at least one of the two allelic products at the same loci or at least two of the several allelic products at different loci. We employed MS-PCR to test the following hemoglobin variants: Hb Constant Spring (Hb CS), Hb E, Hb G-Taichung, Hb J-Meinung, and Hb Kaohsiung. The results were the same as those obtained by amplified created reaction sites (ACRS) or direct sequencing. We conclude that the MS-PCR provides a rapid and simple alternative to other techniques for mutation detection in hemoglobin variants. Moreover, the principle can be extended to other genetic diseases.

    Description / Table of Contents: Summary Comparative theoretical and experimental studies using ebulliometry and vapour pressure osmometry were carried out for the two systems biphenyl-benzene and benzilbenzene at 36.9 °C. A slightly modified vapour pressure osmometer from the company Mechrolab and a recently developed rotating ebulliometer were used for the studies. The ebullioscopic constant of benzene is greater than the vapour pressure constant in the steady state. The experimental results agree with the theory of Kamide and Sanada. For each system, biphenyl-benzene and benzil-benzene, the 2nd ebullioscopic virial coefficientB m is greater than the apparent 2nd vapour pressure osmometric virial coefficientB s′. These results could be explained by dilution effect of the solution droplet in the vapour pressure osmometer.
    Notes: Zusammenfassung Es wurden vergleichende Untersuchungen zur Rotationsebulliometrie und Dampfdruckosmometrie theoretisch behandelt und experimentell in den Systemen Biphenyl-Benzol und Benzil-Benzol bei der Temperatur 36,9 °C durchgeführt. Dabei wurden ein Rotationsebulliometer mit einem Drehantrieb und ein umgebautes Dampfdruckosmometer der Fa. Mechrolab verwendet. Die ebullioskopische KonstanteE m ist für das Lösungsmittel Benzol größer als die dampfdruckosmometrische Konstante im stationären ZustandK s. Die experimentellen Ergebnisse zeigen eine gute Übereinstimmung mit der Theorie von Kamide und Sanada. Für beide Systeme sind bei 36,9 °C die 2. ebullioskopischen VirialkoeffizientenB m größer als die scheinbaren 2. dampfdruckosmometrischen VirialkoeffizientenB s′. Diese Ergebnisse können mit Hilfe des Verdünnungseffektes in dem Lösungstropfen im Dampfdruckosmometer erklärt werden.
