    Notes: Summary We have studied the immunohistochemical reactivity and ultrastructure of both neurofibrillary tangles (NFTs) occurring with severe neurofibrillary diseases, and Pick bodies (PBs) associated with Pick's disease. The NFTs and PBs did not react immunohistochemically with the anti-nonphosphorylated neurofilament monoclonal antibody irrespective of whether they were pretreated with alkaline phosphatase. In granular neurons of the dentate fascia of Ammon's horn in cases of dementia of the Alzheimer type (DAT), NFTs either resembled PB-like inclusion bodies (Horoupian's inclusion bodies) in form, or had a perinuclear structure. Immunohistochemically and ultrastructurally, the NFTs in the dentate fascia in cases of DAT, including Horoupian's inclusion bodies, were similar to the NFTs in the pyramidal neurons of Ammon's horn, which are found most frequently in association with severe neurofibrillary diseases. Under a light microscope, Horoupian's inclusion bodies and PBs could not be differentiated and appeared to be argyrophilic round cytoplasmic inclusions in granular neurons of the dentate fascia. There were, however, ultrastructural differences. Horoupian's inclusion bodies consisted of bundles made up of straight tubules (STs), each about 15 nm in diameter. These bundles were intermixed with a few paired helical filaments which occurred at intervals of about 80 nm. On the other hand, PBs were composed of randomly distributed 15-nm-wide STs, intermixed with a very few fibrillary structures. These fibrils had a periodicity of about 160 nm, and ranged in width from about 15 nm to 30 nm. Horoupian's inclusion bodies associated with DAT and PBs associated with Pick's disease are different in this neuropathological aspect. The NFTs, including Horoupian's inclusion bodies in the dentate fascia in cases of DAT, are considered to be a manifestation of neurofibrillary degeneration.

    Topics: Medicine
    Notes: Summary Patients with olivopontocerebellar atrophy (OPCA) were studied, and cytoplasmic inclusions were observed in some of the remaining neurons of the pontine nuclei, nuclei reticularis tegmenti pontis and arcuate nuclei. The cytoplasmic argyrophilic inclusions were demonstrated by silver impregnation techniques such as Bielschowsky and Bodian staining. With hematoxylin and eosin stain, the inclusions were sharply demarcated and appeared pale. The inclusions were not stained by the following routine histological methods: Klüver-Barrera, phosphotungstic acid hematoxylin, Holzer, periodic acid-Schiff, Mallory azan, alcian blue, nile blue, Masson trichrome, Congo red, thioflavine S, oil red O and Sudan black B stains. Immunohistochemistry with anti-ubiquitin antiserum showed that these inclusions were ubiquitinated. However, the inclusions did not react with any of the following antibodies (Abs) or antisera: anti-phosphorylated neurofilament (NF) Ab, anti-nonphosphorylated NF Abs (160 and 200 kDa), anti-paired helical filament antiserum, anti-tau antiserum, anti-tubulin Abs (alpha and beta), anti-microtubule-associated proteins antiserum, anti-glial fibrillary acidic protein antiserum, anti-vimentin Ab, anti-desmin Ab, anti-cytokeratin Abs (low and high molecular weights), anti-actin antiserum, anti-skeletal myosin antiserum and anti-myelin basic protein Ab. Ultrastructurally, the inclusion bodies noted in OPCA were composed primarily of fibrils having a width ranging from about 24 to 40 nm, which were entirely coated with osmiophilic granular material along their whole length. They were occasionally intermingled with a few filaments about 10 nm in width. Electron microscopical examination on silver-impregnated specimens revealed that each granule-coated fibril had a great affinity for silver particles. In elucidating the pathogenesis of OPCA, it was considered to be an important neuropathological finding that some of the remaining pontine neurons affected by OPCA developed characteristic cytoplasmic argyrophilic inclusions.

    Topics: Medicine
    Notes: Abstract An investigation of Bunina bodies is important when studying the pathoetiology and pathomechanisms involved in amyotrophic lateral sclerosis (ALS). It may serve as a clue essential for the study of the pathogenesis of Guamanian amyotrophic lateral sclerosis (ALS-G), and it may provide a means of answering the question of whether ALS-G is the same disease as classical ALS or a different entity. In ALS-G, however, no precise histochemical, immunohistochemical, or detailed ultrastructural examination has been published to date. To elucidate the pathological differences/similarities of Bunina bodies between classical ALS and ALS-G, we performed histochemical, immunohistochemical, topographic and ultrastructural examinations. Histochemically, hematoxylin and eosin, Masson’s trichrome, methylgreen-pyronin, phosphotungstic acid-hematoxylin, Klüver-Barrera, Bodian and periodic acid-Schiff staining were utilized. Immunohistochemical examination was performed using antibodies for cystatin C, ubiquitin, Tau-2, Cu/Zn superoxide dismutase, phosphorylated neurofilament and glial fibrillary acidic protein. Histochemical findings were consistent with those previously described for classical ALS. The immunohistochemical study showed that in ALS-G Bunina bodies were intensely labeled by an anti-cystatin C antibody. Topographic examination demonstrated that Bunina bodies were distributed in the spinal anterior horns and Clarke’s column in the spinal cord. Ultrastructurally, Bunina bodies were composed of electron-dense amorphous/ granular material accompanied by vesicular structures and neurofilaments. The results of the present study have revealed that the pathological features of Bunina bodies in ALS-G are identical to those seen in classical ALS. These findings strongly suggest that a similar degenerative process occurs in the spinal anterior horn cells in both ALS-G and classical ALS.

    Description / Table of Contents: Résumé 1. Un état diabétique est démontré chez des souris d'une souche japonaise, la souche KK, mis en évidence par une élévation du sucre sanguin et par une diminution de la tolérance au glucose. 2. Le poids corporel des souris KK dépasse la normale; il s'agit d'une obésité modérée. 3. L'activité insulinique du pancréas et le contenu en hormone de croissance de l'hypophyse de souris KK dépassent ceux observés chez des souris C57BL. 4. Histologiquement, on trouve chez les souris KK une hypertrophie et une hyperplasie des îlots de Langerhans, une hypertrophie et une dégranulation des cellules B, une abondance de ribosomes et de réticulum endoplasmique des cellules B, un développement marqué de la région de Golgi des mêmes cellules, et une diminution du contenu en zinc des cellules insulaires. D'autres anomalies ont également été observées dans d'autres organes des souris KK, plus particulièrement pour l'hypophyse, le foie, les surrénales et la parathyroïde.
    Abstract: Zusammenfassung 1. Bei Mäusen des KK-Stammes (japanische Zucht) ist mit Bestimmung von Glucosetoleranz und Blutzuckerwerten ein diabetischer Zustand nachweisbar. 2. Das Körpergewicht von KK-Mäusen liegt über der Norm, und es besteht eine leichte Fettsucht. 3. Die Insulinaktivität des Pankreas und der Gehalt der Hypophyse an Wachstumshormon sind bei KK-Mäusen höher als bei C57BL-Mäusen. 4. Das Pankreas der KK-Mäuse zeigt auffallende Veränderungen, wie Hypertrophie und Degranulierung derβ-Zellen, reichlich Ribosomen und endoplasmatisches Reticulum in denβ-Zellen, sowie starke Ausbildung des Golgiapparates und Verminderung des Zinkgehaltes der Inselzellen. 5. Auch andere Organe (z.B. Adenohypophyse, Leber, Nebenniere und Nebenschilddrüse) der KK-Mäuse weisen Veränderungen auf.
    Notes: Summary This review demonstrates the following points:1. By glucose tolerance test and the determination of non-fasting blood sugar values, mice of KK strain (a Japanese strain) have been shown to be in a diabetic state. 2. KK mice have greater than normal body weights, and moderate obesity. 3. Pancreatic insulin activity and adenohypophyseal growth hormone content of KK mice are greater than those of C75BL mice. 4. The pancreas of KK mice presents many striking changes, such as the hypertrophy and hyperplasia of the islets, the hypertrophy and degranulation of B cells, the abundance of B cell ribosomes and endoplasmic reticulum, the enlargement of the Golgi areas of B cells, and the diminution of the zinc content of insular cells. 5. In other organs (eg. adenohypophysis, liver, adrenal and parathyroid) of KK mice, many changes are also observed. The above features of KK mice are discussed in relation to the presumed metabolic disorder in the mice.
