    Notes: Myelin was isolated from the brains of mice 15, 20, 30, and 60 days after birth. The total amount of basic protein present in the isolated myelin was determined by radioimmunoassay. The 4 myelin basic proteins, with molecular weights of 21,500, 18,500, 17,000 and 14,000, were separated by sodium dodecyl sulfate polyacrylamide gel electrophoresis and their relative amounts were determined densitometrically. The absolute amount of each of the basic proteins was calculated from its relative amount on the gel and from the total amount of myelin basic protein in the sample as determined by radioimmunoassay. The results show that between 10 and 30 days after birth each protein accumulates at a characteristic rate so that the molar ratios among the 4 basic proteins are (in descending order according to their molecular weights) 1:5:2:10 during this period. Between 30 and 60 days after birth the 14 K and 18.5 K proteins continue to accumulate at reduced rates while the 21.5 K and 17 K proteins begin to disappear from the myelin membrane; 60 days after birth the molar ratios among the 4 basic proteins are 1:10:3.5:35. These developmental patterns of accumulation are discussed in relation to the possible role of each of the 4 myelin basic proteins in myelination.

    Notes: Abstract A third pediatric case of intramural diverticulosis of the esophagus is reported in an 8-yearold boy. A hiatal hernia, chronic nonspecific esophagitis and defective esophageal motility was also documented in his 10-year-old brother.

    Description / Table of Contents: Zusammenfassung Das in Aachen entwickelte Computersystem für die on-line-Analyse von hämodynamischen Daten ermöglicht im Dialog mit dem Rechner die sofortige Auswertung von Ekg, Drücken und Kälte- bzw. Farbstoffverdünnungskurven. Das Vorgehen bei der Kurvenauswertung sowie die vom Computer angestellten Berechnungen der einzelnen hämodynamischen Parameter werden beschrieben. Bei der Gegenüberstellung der ärztlich-manuellen Auswertung der auf Papier registrierten Druckkurven und der Computerresultate zeigt das in der täglichen Routine seit Oktober 1974 eingesetzte System eine sehr gute Korrelation für die Wellenerkennung und Wellenvermessung. Auch bei Verwendung verschiedener in der Praxis üblicher, flüssigkeitsgefüllter Katheter und des Tip-Manometers bestätigt sich für die Druckregistrierung in den einzelnen Herzabschnitten, daß das Computersystem für alle verwendeten Kathetermaterialien eine zuverlässige Auswertung bringt. Die flexible Konzeption des Computerprogramms mit seiner schnellen Adaptation an neue Fragestellungen erlaubt seinen Einsatz nicht nur in der klinischen Routine sondern besonders bei der Bearbeitung wissenschaftlicher Probleme im Rahmen hämodynamischer Untersuchungen.
    Notes: Summary The computer-system for the on-line-analysis of hemodynamic data developed in Aachen enables the clinical user to perform the immediate on-line analysis of ECG, pressure-curves and thermo- or dye-dilution-curves in a dialog mode. The procedure of pressure analysis as well as the calculations by the computer for the individual haemodynamic parameters are described. The comparison of the medicalmanual evaluation of the pressure curves on paper-registration and the computer results of the same measurement shows a very good correlation for wave-recognitions and wave-measurements for this system, integrated in the daily routine since 24 months. As well in the application of various fluid-filled catheters used in praxis as in tip-manometers it could be proved for the pressure-analysis in the different positions of the heart, that the computer-system produces reliable evaluations for all catheter materials used. The flexible conception of the computer program with its fast adaption to new problems allows its use not only in the clinical routine, but also and especially in the handling of scientific questions in the frame-work of haemodynamic analysis.
