    Notes: Abstract Lysosomal acid phosphatase activity in human and mouse cells was separated into multiple zones by starch gel electrophoresis. One of the two major zones in the mouse was apparently extinguished when genetic information from man and the mouse was combined in proliferating man-mouse somatic cell hybrids. The evidence suggested that the absence of the mouse lysosomal acid phosphatase (mAP-1) was influenced by the human genome. The gene coding for human acid phosphatase (hAP-1) was shown to be unlinked to the presumed human component which extinguished the mouse acid phosphatase (mAP-1). The mechanism of “extinction” is postulated to be a modification in the processing of the mouse lysosomal enzyme. A dimeric structure was suggested for acid phosphatase-1 of man, mouse, and rat since a single hybrid enzyme was expressed in man-mouse and mouse-rat somatic cell hybrids.

    Description / Table of Contents: Es wird über den Beginn einer Untersuchung zur Kristallisationskinetik von Polycaprolacton (Poly(1-oxy-6-oxohexamethylene) (1)) berichtet. Die primäre Keimbildung und das primäre Sphärolith-Wachstum aus der Polymerschmelze werden bei hinreichend hohen Temperaturen verfolgt, wodurch sichergestellt ist, daß das Wachstum der Kristallite durch Keimbildung bestimmt ist. Die kinetischen Daten werden weitgehend mit Hilfe des Avrami-Modells interpretiert, welches sich gut auf die Kristallisation von 1 anwenden ließ.
    Notes: A kinetic crystallization study of polycaprolactone (poly(1-oxy-6-oxohexamethylene) (1)) has been initiated to investigate the primary nucleation and primary spherulitic growth from a polymer melt at temperatures that are high enough to insure nucleation-limited crystallite growth. The analysis of the kinetic data is largely made on the basis of an Avrami model which proved to be well suited for the interpretation of the crystallization of 1.
