    Description / Table of Contents: Zusammenfassung 1. Der aus einer gesunden Familie stammende Patient entwickelte seit dem 10. Lebensjahr eine progressive äußere Augenmuskellähmung; später traten noch eine atypische Retinopathia pigmentosa sowie Innenohrschwerhörigkeit, cerebelläre Ataxie, Pyramidenbahnzeichen, Intelligenzverlust und Schwäche der Gesichtsmuskulatur auf. Wegen eines kompletten AV-Blocks wurde im Alter von 23 Jahren ein Herzschrittmacher implantiert. 2. Eine Augenmuskelbiopsie zeigte eine erhebliche Bindegewebsvermehrung. Im M. biceps brachii wurden bei der histochemischen Untersuchung vereinzelt pathologisch veränderte Fasern vom Typ I mit Lipideinlagerungen gefunden. 3. Bei der elektronenmikroskopischen Untersuchung wurden in den Muskelfasern des M. biceps zahlreiche Lipidvacuolen unter dem Sarkolemm und zwischen den Myofilamentenbündeln sowie Mitochondrien mit parakristallinen Einschlüssen beobachtet. Diese Einschlüsse bestehen aus Untereinheiten, deren Grundmuster im Schnittbild 5 dichte, 50 Å breite Profillinien im Abstand von je 30 Å zeigt. 4. Diese Befunde werden mit den aus der Literatur bekannten verglichen, sie werden als ein Hinweis auf das Vorliegen einer mitochondrialen Stoffwechselstörung interpretiert.
    Notes: Summary 1. This report deals with a patient deriving from a healthy family who developed progressive external ophthalmoplegia at the age of 10. Later he developed pigmentary degeneration at the retina, inner ear deafness, cerebellar ataxia, signs of upper motor neuron damage, impairment of intellectual function and weakness of facial muscles. At the age of 23, a pacemaker was implanted because of a complete AV-block. 2. A biopsy of the levator-palpebrae-muscle revealed increased amounts of collagen tissue. In the biceps-brachii-muscle, the histochemical investigation revealed scattered pathological fibers, all of type I, with increased lipid deposition. 3. An electron-microscopic investigation of the biceps muscle showed many lipid vacuoles subsarcolemmally and between the bundles of myofilaments. These muscle fibers also contained atypical mitochondria with paracristalline inclusions. These inclusions consist of subunits which have a basic pattern of 5 dense lines (50 Å in width). The distance between the lines is 30 Å. 4. These findings are compared with reports in the literature. The findings are interpreted as morphological manifestation of a mitochondrial metabolic defect.

    Notes: Abstract Using the patch-clamp technique in combination with sliced tissue preparation the membrane properties of newborn rabbit area postrema neurons were investigated. The neurons responded upon depolarization with a fast Na +-current followed by an inactivating and non-inactivating K +-current. GABA-activated currents were investigated resulting in a large Cl--conductance, indicating the expression of GABAA-receptors. The expression of glutamate receptor mRNA was studied by in situ hybridization and electrophysiological measurements of these receptors by means of the patch-clamp technique. As a main result it was found that ionotropic glutamate receptors in the area postrema are composed of “flop” variants of the GluA-, GluB- and GluC-subunits.

    Description / Table of Contents: Zusammenfassung Es wird über eine Familie berichtet, in welcher sowohl die Mutter, als auch ihre beiden Töchter an einer congenitalen, langsam progredienten neuromuskulären Erkrankung leiden. Die im Rahmen der Muskelbiopsie zu erhebenden histologischen, histochemischen und ultrastrukturellen Befunde zeigen bei der Mutter das Vollbild der sog. centronucleären Myopathie. Die charakteristischen zentralständigen Kerne mit den umgebenden pericentronucleären Strukturanomalien der Fasern werden nahezu in allen Muskelfasern angetroffen. Bei den Töchtern dagegen sind morphologisch fast ausschließlich die Typ I-Fasern befallen, welche zusätzlich im Durchmesser kleiner als normal erscheinen. Der Nachweis dieser beiden Formen von centronucleärer Myopathie in einer Familie beweist, daß hier offenbar zwei morphologische Varianten, wahrscheinlich sogar Stadien eines Krankheitsbildes vorliegen. Das zusätzliche Vorhandensein einiger weiterer struktureller Besonderheiten (rod bodies, core-ähnliche Areale) unterstreicht die Verwandtschaft der Erkrankung mit anderen congenitalen langsam progredienten Myopathien (nemaline myopathy, central core disease).
    Notes: Summary This report deals with a family in which the mother and her two daughters suffer from a congenital, slowly progressive neuromuscular disease. Histological, histochemical and ultrastructural observations of the mother's muscle biopsy reveal the characteristics of the centronuclear myopathy. In this case central nuclei and pericentronuclear abnormalities of muscle fibers are found in almost all fibers. Biopsies obtained of the two daughters show alterations especially of type I-fibers, which often are smaller than normal. The presence of these two forms of centronuclear myopathy in one family indicates that these may be only different morphological types or states of one illness. Additionally, other structural findings (rod bodies, core like regions) emphasize the similarities with other congenital slowly progressive myopathies (nemaline myopathy, central core disease).

    Notes: Summary Motilin was demonstrated by the immunoperoxidase technique in endocrine cells of the gastrointestinal tract using several specific antisera. Motilin-like immunoreactivity could only be demonstrated with one of these antisera and was observed in Purkinje cells and dendrites of the cerebellum, in pyramidal cells and dendrites of the cerebral cortex and in dendrites of the CA3 field of the hippocampus of the rat. Very low motilin-like immunoreactivity was found in cerebellum as well as in cerebral cortex using radioimmunoassay. However, using reverse phase liquid chromatography combined with UV-detection and radioimmunoassay, no peak of a peptide corresponding to synthetic motilin was detectable in rat cerebellar extracts, in contrast to findings in rat duodenum. The results do not suggest that motilin is an intrinsic neuroactive substance of the cerebellum.

    Notes: Summary The presence, chromatographic properties and localization of neuropeptide Y was demonstrated in postmortem human brain areas of neurologically and neuropsychiatrically normative controls using immunocytochemistry and high performance liquid chromatography combined with radioimmunoassay. NPY-immunoreactivity was found in many regions of the prosencephalon. Numerous perikarya and fibers were present in the neocortex, basal ganglia and limbic-hypothalamic areas. A moderate number of neurons and fibers was observed in the basal forebrain, including the septal complex. A comparative immunohistochemical investigation in perfusion-fixed brains of the old-world ape Saguinus oedipus revealed an almost identical distribution of NPY-immunoreactivity with only minor differences. Colocalization experiments on 1–2 μm thin consecutive paraffin sections revealed a large number of NPY neurons throughout the human neostriatum and amygdaloid complex that were also positive for somatostatin. Our findings indicate that detection of neuropeptides in fresh or fixed post-mortem human tissue by different immunochemical methods may actually reflect the in vivo conditions. In addition, the wide distribution of NPY throughout the human brain and its colocalization with other neurotransmitters suggests a physiological role as neuroactive substance, i.e. neuromodulator in the primate central nervous system.

    Notes: Summary Glucagon- (GLU-IR), glicentin- (GLI-IR) and dopamine-beta-hydroxylase (DBH-IR) immunoreactive neurons were mapped in the medulla oblongata of colchicine pretreated guinea pigs. Numerous GLU-IR and GLI-IR perikarya are located in the area of the nucleus ambiguus, in the adjacent formatio reticularis, and less frequently in the nucleus reticularis lateralis, the nuclei raphe obscurus and commissuralis and the caudal part of the nucleus solitarius. In these nuclei, the coexistence of glicentin and glucagon within the same perikarya is demonstrated. DBH-IR is also found in neurons of the nuclei commissuralis, solitarius and reticularis lateralis (A1/A2 system of Dahlström and Fuxe 1964, 1965). However, a coexistence of GLU/GLI-IR and DBH-IR within the same neuron is not observed.
