    Notes: Summary An autopsy case of unclassifiable presenile dementia is reported. The outstanding pathological findings were as follows; 1. presence of senile plaques, neurofibrillary changes, Pick bodies, Hirano bodies, granulovacuolar degeneration of neurons, etc. 2. numerous Lewy bodies in the brain stem and diencephalon, 3. peculiar swollen neurons with intracytoplasmic, eosinophilic and argentophilic inclusions (“Lewy-like-bodies”) in the cerebral cortices. Detailed study of the last mentioned inclusions indicates that they are almost identical to Lewy bodies, though there are some minor differences, in histochemical and electronmicroscopic findings. Nosologically, this case may represent either a combination of Alzheimer's disease, Pick's disease and idiopathic Parkinsonism with “Lewy-like-bodies” in the cerebral cortices, or a single disease. As far as we know, no similar case been reported.

    Notes: Summary An autopsy case of multiple system degeneration is characterized by the following; (1) progressive dementia and abnormal sleep patterns, followed by Parkinsonian symptoms with terminal akinetic mutism: (2) severe symmetrical degeneration in the thalamus, particularly nucl. medialis thalami, the reticular formation of the brain stem, also the pallidonigral, pallido-Luysian and dentato-rubral systems. As far as we know, there is no case in the literature, of combined system degeneration, which shows such a wide anatomical range of lesions as the present one. Clinico-pathological correlation between dementia and degeneration of the thalamus, and between abnormal sleep-consciousness mechanism and degeneration of the reticular formation are discussed. The extrapyramidal symptoms are discussed from the clinico-pathological aspect. In addition, peculiar eosinophilic bodies are described, which were most frequently found in the putamen.

    Description / Table of Contents: Zusammenfassung Groß- und Kleinhirnrinde, Plexus chorioideus und Rückenmark von Mäusen wurden nach intracerebraler Inoculation einer Hirnemulsion mit Virus der Encephalitis japonica (JEV) elektronenoptisch untersucht, um den Ort der JEV-Replikation zu bostimmen. 72 Std nach der Inoculation bei Beginn der encephalitischen Symptome enthielten 70 bis 80% aller Rindenneurone und Vorderhornzellen viele sphärische Partikel, die meist im zarten endoplasmatischen Reticulum (EPR) und vereinzelt im granulären EPR lokalisiert waren. Die Einzelpartikel zeigten eine gleichförmige Substruktur aus einem elektronendichten zentralen Hof von 25–30 mμ Durchmesser, einer äußeren, weniger elektronendichten Zone und einer äußersten Grenzmembran von 40 mμ Durchmesser. 96 Std nach der Inoculation zeigte das Cytoplasma der Rinden- und Vorderhornneurone sehr viele Vacuolen und Vesiceln. Partikel wurden weit verstreut in den Vacuolen und Vesiceln sowie erstmals im ERP der Sternzellen und Purkinjezellen angetroffen, allerdings in geringerer Zahl. Keine derartigen Partikel wurden in Kontrolltieren und normalen Mäusegruppen angetroffen. Sogenannte eosinophile intranucleäre Einschlüsse in Epithelzellen des Plexus chorioideus zeigten keine derartigen Partikel im Kern oder in den cytoplasmatischen Bläschen. Nachdem keine als JEV identifizierbaren Partikel in Glia- und Endothelzellen nachzuweisen waren, wird angenommen, daß das JEV echt neurotrop ist und sich im EPR der Nervenzellen repliziert.
    Notes: Summary Cerebral and cerebellar cortices, choroid plexus and spinal cord of mice, inoculated intracerebrally with a brain emulsion containing Japanese encephalitis virus (JEV), were studied electronmicroscopically to determine the cell type and the site of JEV replication. 72 hours after inoculation, when the mice began to show encephalitic symptoms, 70 to 80% of all cortical neurons and anterior horn cells contained many spherical particles mostly located in the smooth endoplasmic reticulum and a few in the granular endoplasmic reticulum. The individual particles demonstrated an uniform substructure consisting of an electron dense central core of 25–30 mμ diameter, an outer less electron dense zone and an outermost limiting membrane of 40 mμ diameter. 96 hours after inoculation, the cytoplasm of cortical neurons and anterior horn cells was observed to contain very many vacuoles and vesicles. Particles were found widely scattered throughout the vacuoles and vesicles, and were observed for the first time in the endoplasmic reticulum of the stellate neurons and in Purkinje cells, though fewer. No such particles were observed in control and normal mouse groups. So-called eosinophic intranuclear inclusions of epithelial cells of choroid plexus failed to show any particles in their nuclei or cytoplasmic vesicles. Considering that no particulate matter, identifiable as JEV, was identified within any of the glial cells or endothelium in this examination, it was concluded that JEV was really neurotropic and replicates in the endoplasmic reticulum of the neurons.

    Description / Table of Contents: Zusammenfassung Bioptisch gewonnenes Hirngewebe von 3 Patienten mit subakuter sklerosierender Panencephalitis (SSPE) wurde licht- und elektronenoptisch untersucht. Histologisch boten alle Fälle gewisse Läsionen der grauen und weißen Substanz. Einschlußkörper wurden in einem Fall mit nur diskreter Markschädigung gefunden. In den beiden anderen Fällen, in denen Kerneinschlüsse nicht nachweisbar waren, trat die Astrogliaproliferation im Mark stärker hervor. Elektronenmikroskopisch ergaben sich vier abnorme Befunde, die aber nicht in allen Fällen obligat angetroffen wurden. Zwei Typen von Nucleocapsid-Strukturen, kleinere und größere, ähnlich jenen in Masern-infizierten Zellen, wurden in einem Fall gesehen. Die kleineren Nucleocapside bildeten entweder Kern- oder Cytoplasmaeinschlüsse; die größeren waren gewöhnlich im Cytoplasma angehäuft. Kernkörperchen fanden sich in allen Fällen. Gitterartige Strukturen und Bündel von fibrillärem Material wurden ferner in zwei Fällen beobachtet.
    Notes: Summary Brain tissue obtained by biopsy from three patients with subacute sclerosing panencephalitis (SSPE) was examined under the light and the electron microscope. Histologically all the cases showed some degree of abnormality of both the gray and the white matter. Inclusion bodies were found in one case in which changes in the white matter were minimal. In the other two cases, where inclusion bodies were not identified, astrocytic proliferation in the white matter was more conspicuous. In electron microscopy four abnormal findings were observed, but all were not necessarily seen in each case. Two types of nucleocapsid structures, smaller and larger, of the type seen in measles-infected cells, were identified in one case. The smaller nucleocapsids formed either nuclear or cytoplasmic inclusions and the larger ones usually aggregated in the cytoplasm. Nuclear bodies were seen in all the cases. Lattice-like structures and bundles of fibrillar material were also observed in two cases.

    Notes: Abstract. Histological, immunohistochemical, and electron microscopic evidence of an extracellular, or ghost Pick body has been found in the granular cell layer and, rarely, in the pyramidal cell layer of the hippocampus of an autopsy case of Pick's disease. The ghost Pick body appeared as a blurred, weak argyrophilic mass in the neuropil, and it was composed of accumulated fibrillary structures, 13 nm in diameter, intermingled with glial filament bundles. These ghost Pick bodies did not react with anti-tau and antiubiquitin antibodies, but did react weakly with antiglial fibrillary acidic protein antibody, whereas intracytoplasmic Pick bodies were strongly immunolabeled with anti-tau but only weakly with anti-ubiquitin antibodies. These results suggest that the Pick body is discharged into the neuropil after destruction of the mother neuron, loses its immunoreactivity to certain tau and ubiquitin antibodies during this process (thereby inducing a glial reaction) and remains in the neuropil as a ghost Pick body.

    Notes: Abstract We examined the cerebellar dentate nucleus (CDN) in 16 patients with hereditary dentatorubral-pallidoluysian atrophy (DRPLA), one of the neurodegenerative diseases caused by expansion of a CAG repeat encoding a polyglutamine tract in the disease protein. In all patients, some CDN neurons were found to contain ubiquitinated filamentous inclusions in their cytoplasm. On hematoxylin and eosin preparations, these filamentous inclusions were eosinophilic, basophilic or amphophilic, and were often found in areas of pale cytoplasm. Electron microscopy revealed that they consisted of bundles of filaments that were somewhat thicker than neurofilaments. These features of the present inclusions were indistinguishable from those of skein-like inclusions (SLI) previously described in the lower motor neurons in sporadic amyotrophic lateral sclerosis. We conclude that SLI can also occur in the CDN in DRPLA and believe that they reflect a characteristic pathological process in this disease.
