    Description / Table of Contents: Zusammenfassung Mit der Methode von Falck-Hillarp lassen sich im Rückenmark der Vögel Bündel fluoreszierender Nervenfasern nachweisen, die in Höhe des Glykogenkörpers (Lumbalwulst) seitlich an dieses Organ grenzen, von wo aus zahlreiche Fasern in den Glykogenkörper eindringen. Vergleichend-anatomisch gehören die fluoreszierenden Areale des Rückenmarks zu den autonomen Zentren. Es wurde versucht, mit Pharmaka, die das autonome Nervensystem beeinflussen oder Krämpfe erzeugen, das Glykogen des Lumbalwulstes zu mobilisieren (Quantitative Glykogenbestimmung nach Krisman, 1962). Besondere Beachtung verdient die elektronenmikroskopische Feinstruktur der Zwickelräume zwischen den großen Glykogenkörperzellen, wo Ausläufer dieser Zellen und Nervenfasern eng beieinander liegen. Die Kapillaren des Glykogenkörpers werden fast vollständig von Ausläufern seiner Zellen umscheidet.
    Notes: Summary With the method of Falck-Hillarp bundles of fluorescent nerve fibers were observed in the vicinity of the avian lumbar glycogen body. They encompass the glycogen body laterally. Numerous fluorescent fibers penetrate from this border zone into the glycogen. The fluorescent regions of the avian lumbar spinal cord belong to the autonomic centers. Attempts were made to decrease the high glycogen content of the glycogen body by administering drugs which act on the autonomic system, and also by using convulsant drugs. Glycogen was estimated quantitatively by the Krisman method (1962). Electron micrographs show that the triangular spaces between the enlarged cells of the glycogen body are occupied by the processes of these cells and by nerve fibers. The capillaries of the glycogen body are nearly completely ensheathed by the processes of the glycogen-body cells.

    Notes: Two series of glass-reinforced diallyl phthalate molding compounds from two different manufacturers were evaluated using a Rheometrics, Inc. Mechanical Spectrometer and a Brabender Torque Rheometer. Comparison of reactivity and minimum viscosity as measured by these two instruments is presented. The Mechanical Spectrometer appears capable of differentiating smaller changes in melt viscosity than does the Brabender Torque Rheometer.
