    Notes: Summary Immunohistochemistry was used to investigate the distribution pattern of calcitonin gene-related peptide (CGRP) nerve fibers in the laryngeal mucosa, glands and intrinsic muscles of the dog. CGRP immunoreactive nerve fibers were found more frequently than substance P immunoreative nerve fibers in every region of the larynx. In the epithelia, CGRP nerve fibers were mainly found in the epiglottis, arytenoid region and subglottis. Many taste buds were observed in the arytenoid region and were densely innervated by the CGRP nerve fibers. In the lamina propria, the plexus of CGRP nerve fibers was present, with some of these fibers associated with blood vessels. Laryngeal glands were also innervated by a few CGRP nerve fibers. In the intrinsic laryngeal muscles, abundant immunoreactivity was observed and many motor end-plate-like structures were found with CGRP immunoreactivity. These findings strongly suggest that CGRP plays an important role in all of the sensory, motor and autonomic nervous systems of the larynx.

    Notes: Summary The sympathetic innervation of the canine larynx was investigated using tyrosine hydroxylase (TH) immunohistochemistry. Many tyrosine hydroxylase immunoreactive (TH-IR) nerve fibers were observed around arteries and arterioles in the laryngeal mucosa and intrinsic laryngeal muscles. In the glandular region, TH-IR fibers were also found, with some of these fibers terminating around the basement membranes of the glandular cells. The quantity of TH-IR fibers in the mucosa differed among regions of the larynx. Many of these fibers could be found in the laryngeal surface of the epiglottis as well as the posterior glottis. These findings suggest that TH-IR fibers may directly innervate muscles in the intrinsic larynx.

    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.
