    Notes: This study was designed to determine whether painful electrical stimulation of the tooth pulp induces centrally mediated reflex vasomotor changes in human gingiva and whether the sympathetic nervous system is involved in the vasomotor responses. Dynamic changes in maxillary gingival blood flow (GBF) following painful electrical stimulation of the mandibular lateral incisor were investigated, by means of laser-Doppler flowmetry, in both healthy volunteers and patients undergoing sympathetic blockade for hyperhidrosis. Increases in GBF were observed in both healthy volunteers and patients on the ipsilateral side without an increase in systemic blood pressure, but the evoked GBF increase disappeared when pain sensation was abolished by local anesthetization with 2% xylocaine solution. The vasodilator responses did not differ in amplitude between before and after the sympathectomy. These results suggest that painful tooth stimulation evokes centrally mediated reflex vasodilation, presumably via parasympathetic efferent fibers, in the human gingiva and that sympathetic vasomotor mechanisms are not involved in these responses.

    Notes: Summary Darier's disease is an autosomal dominant skin disorder that is characterized by multiple keratotic papules, focal loss of adhesion and abnormal keratinization. Mutations in the ATP2A2 gene encoding sarco/endoplasmic reticulum calcium pumping ATPase type 2 have been identified as the molecular basis of Darier's disease. Segmental Darier's disease is a rare type of Darier's disease in which there is characteristic localization of the keratotic papules in a linear pattern following Blaschko's lines. In this study we examined ATP2A2 mutations in a Japanese patient with segmental Darier's disease. The samples from affected skin, unaffected skin and peripheral leucocytes were subjected to polymerase chain reaction (PCR). Direct sequencing of the PCR products was performed. Sequence analysis revealed that the patient had 160A→G substitution mutation which predicts I54V. This novel mutation was present in the affected skin, but not in the unaffected skin or peripheral leucocytes. This is the first report of segmental Darier's disease caused by mosaicism for an ATP2A2 mutation in Japan.

    Description / Table of Contents: Zusammenfassung Kleine protoplasmatische Körnchen, welche in verschiedenen verhornenden Epithelien gefunden worden sind und als der Zellmembran aufliegende Körnchen oder Keratinosome bezeichnet wurden, konnten durch Phospholipase C gespalten werden. Körnchen, die in die intercellulären Zwischenräume abgestoßen waren, waren gleichfalls durch Phospholipase C spaltbar. Da angenommen wird, daß Phosphatide einen Teil der intercellularen Kittsubstanz bilden, nicht nur in der Haut, sondern auch in anderen eng zusammengefügten Epithelien, wird die Bezeichnung „Kittkörnchen“ oder „Kittkörper“ für diese Körnchen vorgeschlagen.
    Notes: Summary Small cytoplasmic granules, which have been found in various keratinizing epithelia and called the membrane-coating granules or keratinosomes, were found to be amenable to phospholipase C digestion. Granules discharged into the intercellular spaces could also be digested with phospholipase C. Since it is believed that phospholipids are part of the intercellular cement not only in the skin but in other tightly junctioned epithelia, the name “cement granule” or “cementsome” was proposed for these granules.

    Description / Table of Contents: Zusammenfassung Die Nagelzellen, die von den ventralen, apikalen und dorsalen Anteilen der proximalen Matrix gebildet wurden, rückten in axial-distaler Richtung vorwärts, bis sie amproximalen Verhornungspunkte zusammentrafen. Von diesem Punkte an wurden der proximalen Nagelplatte ununterbrochen Zellen von der ventralen und dorsalen Matrix und vom Nagelbett zugefügt. Bald hörte die dorsale Matrix auf, Nagelzellen zu entwickeln und wurde weiter distal in den hinteren Nagelfalz umgewandelt. Mit der differentialen Phasenkontrast-Apparatur von Zeiss-Nomarski konnte man die Teilung der proximalen Nagelplatte in eine ventrale und dorsale Hälfte erkennen. Nächst der Lunula entwickelte das Nagelbett noch eine weitere deutliche Schicht unter der proximalen ventralen Schicht. Elektronmikroskopisch zeigten alle Nagelzellen, ohne Rücksicht auf ihren Ursprung, Verhornung durch Anhäufung von Fibrillen ohne Bildung von Keratohyalinkörnern. Membrane-coating granules (MCG) entstanden in reichlicher Menge. Sie wurden abgestoßen und bildeten die intercellulßre Kittsubstanz. Das abgestoßene Material erweiterte einige der engen Membranspalten, während es gewöhnliche, klaffende (nicht-spezifische) Zellgrenzen verengte und dadurch 150–180 Å weite intercelluläre Zwischenräume bildete, nämlich dieengen Zellverkittungen. Die engen Zellverkittungen stellten den häufigsten Typ der intercellulären Anlagerung dar, wodurch die verhornten Nagelzellen zusammengehalten wurden. Die dicke Zellhülle der verhornten Zellen, nämlich dasGrenzband, wurde durch Niederschlag von dichtem Material an der protoplasmatischen Seite der Zellmembran gebildet und nicht durch die membrane-coating granules.
    Notes: Summary The nail cells produced in the ventral, apical and dorsal portions of the proximal matrix moved in axiodistal direction to meat together at theproximal point of keratinization. The proximal nail plate from this point on was added continuously by the cells from ventral matrix and nail bed. Dorsal matrix soon ceased to produce nail cells and further distally transformed into the posterior nail fold. With Zeiss-Nomarski differential interference contrast equipment, the proximal nail plate could be divided into the ventral and dorsal halves. Near the lunula the nail bed produced one more distinct layer beneath the proximal ventral layer. Electron miscroscopically all nail cells regardless of their origins were seen keratinizing by accretion of tonofibrils without formation of keratohyaline granules. Membrane-coating granules (MGG's) were produced in abundance. They were discharged and provided the intercellular cement. The discharged material widened some of the gap junctions while it tightened nonspeccific junctions to produce 150–180 Å intercellular spaces, i.e. thenarrow junctions. The narrow junctions were the most common type of intercellular junction connecting the keratinized nail cells. The thick cellular envelope of the keratinized cells, i.e. themarginal band, was formed by a precipitation of dense material on the cytoplasmic side of the plasma membranes and not by discharged MCG's.

    Notes: Summary Neurological and electrophysiological examination of 15 workers handling acrylamide in a factory revealed abnormal signs of peripheral nerve functions in all cases. Neurological abnormalities were: absent deep reflexes, decreased superficial sense and suppressed vibration sense. Action potentials in median nerve and tibial nerve were greatly reduced while conduction velocity was not greatly affected. Long-experienced workers had various complaints with ataxic gait and showed abnormal EEG.
