    Description / Table of Contents: Zusammenfassung Es wurde eine neue Methode zur Identifizierung von fetalem Hämoglobin (Hb F) in Blutspuren mit der umgekehrten Phase-Hochleistungsflüssigkeitschromatographie durchgeführt. Die Unterscheidung zwischen fetalen Blutspuren und denen von Erwachsenen erfolgte aufgrund der Existenz der Spitzen der γ-Ketten von Hb F. In den Chromatogrammen der untersuchten Blutspuren von Erwachsenen traten fast keine γ-Ketten auf. Diese Methode ermöglichte ferner die Bestimmung des Hb F-Wertes mit dem Flächenverhältnis der Globin-Ketten auf den Chromatogrammen. Hb F-Werte der sechs Fälle von Nabelschnurblutspuren auf dem Filterpapier lagen zwischen 81.1% und 91.3%. Die vorliegende Untersuchung zeigt, daß sich der Hb F-Wert für mindestens 12 Wochen nicht ändert. In der Praxis der Rechtsmedizin ist diese Methode im Hinblick auf die Einfachheit, hohe Empfindlichkeit, Schnelligkeit und Zuverlässigkeit sehr wertvoll.
    Notes: Summary A new method for the identification of fetal hemoglobin (Hb F) in blood stains by reverse-phase high performance liquid chromatography is described. Differentiation between fetal and adult blood stains is based on the existence of γ-chain peaks which are characteristic of Hb F. Very few γ chains appeared on chromatograms of all the adult blood stains examined. The level of Hb F could be determined by measuring the total of chromatogram γ-globin chain areas, and expressing it as a percentage of total Hb. Levels in six cord blood stains on filter paper ranged from 81.1% to 91.3% and remained constant for at least 12 weeks. This method is of great value for its simplicity, sensitivity and speed, and most importantly for its reliability in the field of forensic medicine.

    Notes: The surface coverage of porous glass (PD = 500 Å) by styrene adsorbed from its vapor (0.1-6 torr) was studied in a vacuum electrobalance. The adsorption isotherm of the monomer was analyzed by the BET method, and a full monolayer coverage was found to form at a relative pressure of 0.11, weighing 6 mg per gram of glass. Polymerization in submonolayers of adsorbed styrene was initiated by thermal decomposition of predeposited BPO and found to continue until all initiator decomposed, sample cooled, or vapor removed, hence allowing a controlled film thickness. The films were extracted in THF and analyzed by computerized GPC. Molecular weights were in the range 18000-69000. These were related to the rates of polymerization by the usual statistical correlations.
