    Notes: A conditioned medium from cultured human epidermal cells was observed to inhibit the activity of exogenous urokinase. By reverse fibrin autography after SDS polyacrylamide gel electrophoresis, a plasminogen activator inhibitor was detected with a molecular weight of 46000. Using Mr- 33000 [125I]-labelled urokinase we observed the formation of an enzyme-ligand complex. The molecular weight of this complex was 79000. These results indicate that cultured human epidermal cells secrete a plasminogen activator inhibitor (urokinase inhibitor) with a molecular weight of 46000.

    Notes: A plasminogen activator (PA), Mr 72 000, was detected in conditioned medium from human melanocyte cultures by fibrin autography. The electrophoretic mobility was identical to that of tissue PA produced by Bowes melanoma cells. PA activity in human melanocyte culture medium was inhibited by anti-tissue PA IgG, but not by anti-urokinase IgG. Our results are the first to show that normal human melanocytes in culture secrete tissue plasminogen activator.

    Notes: Blood vascular and lymphatic tumors were evaluated immunohistochemically by studying a spectrum of endothelial associated antigens. (1) UEA-I lectin reacted with the tumor cells of one patient with malignant angioendothelioma in the non-metastatic stage. However, when metastasis occurred, the binding sites of this lectin completely disappeared from the surface of the tumor cells in both original and metastatic lesions, suggesting the loss of blood group H antigen from the tumor cells could be used as an indicator of metastasis in this tumor. (2) Reaction with anti-HLA-A, B, C, intense in normal blood vessels, remained intensely positive in pyogenic granuloma and Kaposi's sarcoma, whereas it did not react with normal lymphatics and lymphangioma. This indicates that anti-HLA-A, B, C is useful in differentiating blood vascular structures from lymphatic structures in both normal and pathological conditions. (3) OKM5 reacted intensely with benign hyperplasius in pyogenic granuloma, while barely reacting with proliferating parts in Kaposi's sarcoma, suggesting the difference in staining patterns can be used to distinguish vascular proliferation or malignancy. (4) Reaction with anti-Type IV collagen and anti-laminin was intense in normal blood vessels, pyogenic granuloma and Kaposi's sarcoma, whereas reaction with these antibodies in normal lymphatics was patchy and irregular in its thickness.

    Notes: Normal epidermis of various sites of human body was examined by N-(7-dimethyl-amino-4-methyl-3-coumarinyl)maleimidc (DACM) method for SH groups and SS linkages. The horny cells in the palm and sole showed a gradual occurrence of a SH membranous pattern, while those in other sites revealed an abrupt formation of the SH membranous pattern just above the granular layer. In the palm and sole epidermis the number of layers which exhibit membranous pattern of SH-positivity was thicker than that in the other epidermis; the low- through mid-layers of horny cells in the former sites seemed to contain not only SS-positive but also SH-positive substance at cell peripheries. The DACM staining for SS linkages showed the presence of a granular fluorescence in the cytoplasm of the granular cells of the epidermis in the human palm and sole, but not in other sites. The granular cells in human lip displayed a granular fluorescence in the cytoplasm by cither SH or SS DACM staining. All the SH- or SS-positive granular fluorescence was related to keratohyaline granules. These findings indicate that there may be some variations of the distribution pattern of the epidermal cellular proteins with SH and/or SS and a difference in chemical composition of keratohyaline granules between different anatomical sites of human body.

    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.

    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.

    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.
