    Description / Table of Contents: Zusammenfassung Von 21 Fällen von Whipplescher Krankheit in der Sammlung des Armed Forces Institute of Pathology zeigten 4 Fälle neurologische Symptome mit besonders ausgeprägten Hirnläsionen. Lichtmikroskopisch bestanden die Herde aus knötchenförmigen Anhäufungen von Makrophagen, deren Cytoplasma mit Hämatoxylin-Eosin eine charakteristische schwachblaue und nach Durchführung der Perjodsäure-Schiff-Reaktion eine stark rote Färbung zeigte. Elektronenmikroskopisch fanden sich in den Hirnläsionen Bacillen, die morphologisch den im Darm beschriebenen glichen und die auch dieselben Degenerationserscheinungen aufwiesen. Die Perjodsäure-Schiff-Reaktion färbt Kapselmaterial und Zellwände,die auch nach Untergang der Bacillen noch nachweisbar sind. Diese Beobachtungen werden als weiterer Beweis für die infektiöse Ätiologie der Whippleschen Krankheit angeführt.
    Notes: Summary Among the 21 autopsied cases of Whipple's disease on file at the Armed Forces Institute of Pathology, 4 had neurological symptoms and prominent involvement of the central nervous system, By light microscopy the lesions were composed of nodular aggregates of macrophages having cytoplasm that stained a distinctive pale blue with hematoxylin-eosin and bright red with the periodic acid-Schiff technique. By electron microscopy the cerebral lesions revealed bacilli morphologically identical to and undergoing the same sequence of degenerative changes as those observed in the intestine. The periodic acid-Schiff reaction stains the walls and the capsular material that persists even after intact organisms disappear. These observations further support the infectious nature of Whipple's disease.

    Description / Table of Contents: Zusammenfassung Hirngewebe eines Falles von Pickscher Krankheit wurde licht-und elektronenmikroskopisch untersucht. Intraneuronale argentophile Picksche Körper wurden am zahlreichsten in den Pyramidenzellen des Hippocampus gefunden. Elektronenoptisch bestanden die Einschlußkörper aus einer Zusammenballung von körnigen Gebilden, die in einem unregelmäßigen Netz von vermehrten Neurofilamenten verstreut lagen. Viele eosinophile Hiranosche Körper fanden sich in nächster Nachbarschaft von Nervenzellen. Diese Körper bestanden aus verflochtenen Schichten von geperlten oder glatten Filamenten. Die mögliche Lokalisation der Hiranoschen Körper innerhalb von degenerierenden Axonendigungen wird diskutiert.
    Notes: Summary Brain tissue from an autopsied case of Pick's disease was studied by light and electron microscopy. Intraneuronal argentophilic Pick bodies were most numerous in the pyramidal cells of the hippocampus. By electron microscopy, these inclusions consisted of a conglomeration of granules enmeshed in an irregular network of proliferated neurofilaments. There were also multiple eosinophilic juxtaneuronal structures (Hirano bodies). By electron microscopy these consisted of interwoven sheaves of beaded and continuous filaments. The possible location of the Hirano bodies within degenerating axonal terminals is discussed.

    Notes: Summary Increased endoneurial pressure of up to 17.0 cm H2O was recorded in the peripheral nerves of rats fed hexachlorophene in their laboratory diet. The pressure was measured using a micropressure transducer developed for recording pressure in the microcirculation. The results were correlated with morphologic findings. Teased nerve fibers and aralditeembedded specimens of hexachlorophene damaged sciatic nerve revealed the characteristic severe intramyelinic edema due to splits in the minor dense lines of compact myelin giving rise to wide interlamellar spaces as shown in previous studies. The endoneurial pressure of rats exposed to hexachlorophene for 11 days and subsequently fed a normal diet returned to normal (0.2–3.0cm H2O) after 12 days, and morphologic examination showed few residual abnormalities. Prolonged exposure to hexachlorophene for up to 4 weeks caused widespread axonal degeneration in addition to intramyelinic edema. Animals treated with hexachlorophene for 21 days followed by a normal diet for 14 days showed degenerated axons, phagocytosis of myelin as well as interstitial edema and elevated endoneurial pressure. It is suggested that axonal degeneration in hexachlorophene neuropathy is caused by increased endoneurial pressure.

    Notes: Summary The fine structure and reproductive mechanisms of Toxoplasma gondii are described in a case of toxoplasma encephalitis. Replication was observed in glial cells by an internal budding process: endodyogeny. Distinctive ultrastructural features associated with host cell penetration, and encystation are described. Electron microscopic features previously reported in tissue culture and in experimentally produced infections with T. gondii are confirmed in the human brain tissue.

    Notes: Summary A caucasian male with a history of mental retardation and intractable epilepsy since birth, developed progressive wasting and weakness of skeletal muscles, leading to death at 4 years of age. A biopsy of gastrocnemius muscle at 2 years of age revealed severe neurogenic atrophy. Sural nerve biopsies at 2 and 3 years showed progressive atrophy and loss of large myelinated nerve fibers with a paucity of neurofilaments in remaining nerve fibers. Postmortem immunohistochemical and ultrastructural examination showed that neurons were markedly distended by phosphorylated neurofilaments. Whereas large lower motor neurons were most severely involved, dorsal root ganglia and neurons in the cerebral cortex and deep gray nuclei were also affected. It is suggested that this disease is caused by a disorder of neurofilament phosphorylation and transport.

    Notes: Summary Two older patients with Down's syndrome and widespread neurofibrillary tangles and senile plaques were studied by light and electron microscopy. The ultrastructural demonstration of twisted tubules verified the assumption that the tangles encountered in these patients were Alzheimer's neurofibrillary tangles. Despite the morphological evidence of Alzheimer's disease, neither of these patients were clinically demented.

    Notes: Summary Distinctive cytoplasmic alterations of Schwann cells were observed by electron microscopy in rats and mice with peripheral neuropathy induced by chronic exposure to 2,5-hexanedione. Pronounced enlargement of Schwann cells was due to accumulation of 100 Å cytoplasmic filaments and endoplasmic reticulum and was most often observed after 12–15 weeks exposure to 2,5-hexanedione. Examination of teased nerve fibres revealed segmental demyelination and remyelination involving axons of normal diameter as well as giant axons. The filament disorder induced by 2,5-hexanedione administration is not limited solely to axoplasmic contents. Possible mechanisms of demyelination are discussed and the changes are compared to those observed in human neuropathy for which 2,5-hexanedione appears to be the closest experimental model.
