    Notes: Summary The fine structure of the neurohypophysis has been studied in normal and histamine-treated rats with particular reference to capillary relationships and to the neurosecretory vesicles. Certain new information on the pericapillary space has been developed and is discussed with reference to the existing literature on the posterior hypophysis and other endocrine organs. The membrane-bounded pericapillary space penetrates deeply between surrounding nerve terminals and pituicyte processes, seemingly forming a pervasive “metabolic lake” which undoubtedly is of physiological significance for metabolic and secretory exchange. Following histamine treatment, the neurosecretory vesicles lose their electrondense centers, the mitochondria in the nerve terminals become swollen, and the capillary endothelium shows evidence of increased pinocytosis. In one rat subjected to painful stimuli, only the first and last of the above alterations are prominent. The experimental results are interpreted in the light of previous work done by other authors, as additional evidence for the identity of the stainable neurosecretion of light microscopy and the neurosecretory vesicles of electron microscopy.

    Notes: Bei der Gefriertrocknung von Lösungen fadenförmiger und kugelförmiger Hochpolymerer, niedermolekularer Zucker und sogar anorganischer Salze wurden Gerüststrukturen von teilweise bemerkenswerter Festigkeit erhalten. Das makroskopische Bild der Trockensubstanzen wird bei allen Stoffgruppen durch die Textur des ausfrierenden Lösungsmittels bestimmt.

    Description / Table of Contents: Solutions of extremely high molecular dextrans show such pronounced deviations from Newtonian behaviour, even in the range of low concentrations, that the determination of shear-independent intrinsic viscosities in the usual manner does not succeed. The rheological behaviour of such dextran solutions is described and methods of evaluation are discussed, which permit the elimination of the effect of rate of shear upon the intrinsic viscosity. Effects of thixotropy are mentioned.
    Notes: Lösungen sehr hochmolekularer Dextrane zeigen noch im Bereich kleiner Konzentrationen so starke Abweichungen vom Newton schen Verhalten, daß die Ermittlung schubspannungsunabhängiger Viskositätszahlen auf dem üblichen Wege nicht mehr gelingt. Das Fließverhalten solcher Dextranlösungen wird beschrieben, und es werden Auswertungsverfahren diskutiert, die bei derartigen Systemen den Einfluß der Scherbeanspruchung auf die Viskositätszahl zu eliminieren gestatten. Auf Thixotropieerscheinungen bei solchen Lösungen wird hingewiesen.
