    Notes: [Auszug] THE preliminary communication of Lehmann1 on the treatment of human tuberculosis with p-amino-salicylic acid led us to undertake a detailed study of this acid. p-Aminosalicylic acid2 is obtained by the reduction of p-nitrosalicylic acid, which itself can be ...

    Notes: [Auszug] IT is generally required in radioactive tracer procedure when applied to biochemical problems that the stable and radioactive molecules or ions possess identical configurations. Only when the two isotopic atoms are supplied in the same chemical form can it be assumed that living tissues will ...

    Description / Table of Contents: Zusammenfassung Die seinerzeit beschriebene Modifikation der Methode vonBarger mit Hilfe von „parallelen Zwillingskapillaren“ zur Bestimmung des Molekulargewichtes durch isotherme Mikrodestillation ist durch die vorstehend wiedergegebene Methode mit Hilfe von „gegenübergestellten Zwillingskapillaren“ dargestellt. Durch Verringern der Länge des Dampfraumes auf ein Minimum von 6 bis 8 mm und Verwendung von geeigneten Lösungsmitteln wurden deutliche, 10- bis 20fach größere Änderungen als bisher in 24 Stunden und endgültige Ergebnisse innerhalb 48 Stunden erhalten. Das Verfahren erfordert für einen Versuch nur 25 mm3 Lösung von 0,5 mg Substanz, die wiedergewonnen werden kann. Der Aufwand an Hilfsmitteln besteht aus drei Kapillaren und ist von äußerster Einfachheit.
    Notes: Summary The previously described “parallel twin capillary” modification ofBarger's method for the determination of molecular weight by isothermic microdistillation, has been superceded by the “opposed twin capillary” method described above. By reducing the actual length of the vapor bridge to a practical minimum of from 6 to 8 mm., and employing suitable solvents, significant readings, ten to twenty times as large as heretofore possible, are obtained in 24 hours and final results within 48 hours. The method requires only 25 cbmm. of solution per trial, involving as little as 0,5 mg. of substance which can be recovered. The apparatus consisting of three capillaries is of utmost simplicity.
