    Notes: Summary Histological observation on the mesenteric lymph node and Peyer's patches of C3H B mice, neonatally thymectomized, lethally irradiated and reconstituted with syngeneic bone marrow cells, showed that a large number of lymphocytes appeared selectively in the restricted territory surrounding the post-capillary venules. Severe depletion of lymphocytes persisted in most of the thymus-dependent areas. Lymphocytes were also observed passing through the walls of the post-capillary venules. Autoradiographic studies on the mesenteric lymph node of recipient B mice 30 minutes after intravenous injection of cells labelled with 3H-uridine and taken from lymph nodes of donor B mice showed that B lymphocytes could penetrate the walls of the post-capillary venules from the blood into the peripheral lymphoid tissues. The post-capillary venules, which are known as the recirculating route of T lymphocytes in normal animals, are thought to be the pathway of migrating B lymphocytes in B mice.

    Description / Table of Contents: Zusammenfassung Die Kleinwinkelstreuung der Neutronen von A1-6.8 at % Zn und Al-6.8 at % Zn- 0.1 at % Mg-Legierungen während der Guinier-Preston-Zonen-Bildung wurde am KUR (Kyoto Universität Reaktor) gemessen. Die Proben wurden aus 300 °C in Salzwasser von — 20 °C abgeschreckt und bei 77 K gehalten. Sie wurden bei 40 °C während der verschiedenen Zeitdauer von 0 bis 1000 Minuten mit der nachfolgenden Neutronenmessung bei 77 K gealtert. Die gemessene zeitliche Entwicklung des Streuquerschnittes kann qualitativ erklärt werden in übereinstimmung mit Saitos Formel, die aus zwei verschiedenen Teilen besteht, die der inkohärenten anomalen Schwankung und der kohärenten geordneten Struktur der Konzentration entsprechen.
    Notes: Summary Small-angle neutron scattering from A1-6.8 at % Zn and Al-6.8 at % Zn-0.1 at % Mg alloys during Guinier-Preston zone formation have been measured at KUR (Kyoto University Reactor). The samples were quenched from 300 °C into brine at -20 °C and kept at 77 K. They were aged at 40 °C for various periods ranging from 0 up to 1000 minutes each with subsequent neutron measurement at 77 K. The observed temporal evolution of the cross section can be interpreted qualitatively in terms of Saito's formula which consists of two distinct parts due to the incoherent anomalous fluctuation and to the coherent ordered structure of the concentration.
