    Notes: Summary. During the period from 1 October 1979 to 31 January 1981, 548 estimations of maturity were made on 523 infants at the Department of Medical Obstetrics of the Neukolln Hospital in Berlin, using the motor nerve conduction velocity (NCV) of the ulnar nerve combined with the Farr system. The mean value of the NCV increases from 13.0 m/s in the 33rd week of gestation to 30.4 m/s in the 44th week. Over the whole range the NCV showed a highly significant correlation (r=0.946, P〈0.00001) with the gestational age of the infant, whereas the Farr system deviated strongly in a false positive direction up to the 38th week of gestation. The measurement of the NCV of the ulnar nerve is a simple and very precise postpartum estimation of the gestational age.

    Radioimmunoassay of serum SP 1 and HPL in normal and abnormal pregnancies (1979)

    Description / Table of Contents: Summary Serum concentrations of the pregnancy-specific β1-glycoprotein (SP 1) and human placental lactogen (HPL) were measured by radioimmunoassay in 372 blood samples obtained from 40 women in the second half of a normal singleton pregnancy. The mean level of SP 1 steadily increased from 40 μg/ml in the 22nd week of pregnancy to 168 μg/ml in the 36th week of gestation and thereafter reached a plateau. The half-life of SP 1 during the first week after delivery was about 39 h. The clinical value of SP 1 in comparison to HPL estimations was assessed in a prospective study of a few high risk pregnancies. There were no significant differences between serum SP 1 and HPL levels in pregnancies complicated by preeclampsia with or without intrauterine growth retardation and in twin pregnancies. Serum HPL and SP 1 levels were equally effective in predicting placental insufficiency with fetal growth retardation.
    Notes: Zusammenfassung Zur Bestimmung des schwangerschaftsspezifischen β1-Glykoproteins (SP 1) wurde ein Radioimmunoassay entwickelt. Die Normalbereiche für SP 1 und das humane Plazenta-Laktogen (HPL) in der zweiten Schwangerschaftshälfte bestimmten wir aus 372 Serumproben von 40 ungestörten Schwangerschaftsverläufen. Der Median von SP 1 stieg von 40 μg/ml in der 22. SSW auf 168 μg/ml in der 36. SSW kontinuierlich an und blieb danach bis zum Schwangerschaftsende nahezu unverändert. Aufgrund der Eliminationsrate von SP 1 in den ersten 6 Tagen post partum konnte die Halbwertszeit mit etwa 39 h berechnet werden. In einer prospektiven Studie wurde aus einem Kollektiv von Risikoschwangerschaften die Aussagekraft von SP 1 im Vergleich zu HPL untersucht. In Übereinstimmung mit HPL lagen fast alle SP 1-Werte bei Zwillingsschwangerschaften über dem Normbereich. In Fällen von leichter bis mittelschwerer EPH-Gestose mit normaler Kindsentwicklung befanden sich beide Parameter im Normbereich. Bei leichter fetaler Mangelentwicklung bewegten sich die SP 1-Serumspiegel unterhalb des Medians (10.–50. Perzentile). Hingegen verliefen die Kurven für SP 1 in Fällen von schwerer fetaler Mangelentwicklung weit unterhalb der 10. Perzentile des Normalbereichs. Ähnlich verhielt sich HPL. SP 1 kann ebenso wie HPL zur biochemischen Überwachung der Schwangerschaft herangezogen werden. Unsere Untersuchungen ergaben, daß SP 1 keine entscheidenden, über HPL hinausgehenden Informationen erbrachte. Die Einführung von SP 1 als zusätzlichen Parameter zur routinemäßigen Überwachung von Risikoschwangerschaften in der 2. Schwangerschaftshälfte ist daher derzeit nicht notwendig.

    Description / Table of Contents: Zusammenfassung Das Geburten-Dokumentations-System wurde zur Erleichterung der Dokumentation und zur Qualitätskontrolle in der Geburtshilfe entwikkelt. Ein Personal-Computer dient zur Erfassung der wichtigsten Daten des Schwangerschafts-, Geburts-, und Wochenbettverlaufes. Dadurch wird die konventionelle Geburtenbuchführung ersetzt und die automatische Arztbriefschreibung ermöglicht. Mit Statistikprogrammen steht für den klinischen Routinebetrieb ein Informationssystem zur Verfügung, das auch die Erstellung der gesetzlich geforderten geburtshilflichen Statistik und eine klinikbezogene Qualitätskontrolle erlaubt.
    Notes: Summary A simple on-line data collection system was developed for facilitating documentation and quality assessment in perinatal medicine. A microcomputer is used for acquisition of the most important obstetrical data. The system substitutes the handwritten birth notification form and permits automatic medical reporting. In addition an information system for day-to-day clinical routine is provided. Special programmes allow the complication of statistical analysis as requested by the government as well as for actually internal quality assessment.

    Notes: Abstract Influence of the structure of styrene and polystyrene modified PE membranes on their permeation properties is presented. It is demonstrated that the temperature of styrene treatment (N membranes) and the presence of polystyrene (P membranes) results in high differentiation of the permeation properties. SALS studies have shown the structural reorganization depending on modification extent and diffusion of the penetrant. It is also shown that the morphology of the dried films remains unchanged. This work proves that the appropriate modification of PE films results in membranes with controlled permeation behavior.

    Notes: Abstract In this paper the structure correlation of PE-PS gradient polymers, modified by styrene LDPE films with their mechanical and rheo-optical properties, is presented. The specific structural changes of both the investigated materials can be demonstrated by using dynamic mechanical deformation studies. The influence of the penetrant on LDPE crystalline and amorphous phase order is shown. Some interesting mechanical behaviour of the gradient polymers, depending on the polystyrene contents, is discussed.
