    Notes: Zusammenfassung Es wird über Versuche mit Sorboylpalmitat berichtet, einem neuartigen chemischen Hilfsstoff für Brot und andere hefegetriebene Backwaren. Sorboylpalmitat stört die Teiggärung nicht, ist in backtechnischer Hinsicht gut geeignet, beeinflußt die organoleptischen Eigenschaften des Brotes nicht und verhindert des Verschimmeln des Brotes.

    Notes: Summary A case of small cell neuroendocrine (oat cell) carcinoma of the breast in a 52-year old male is presented. Oat cell carcinomas have been reported in various extrapulmonary sites, but this is the second case of a primary oat cell carcinoma of the breast and the first one to have been documented in a male. The tumor was investigated histologically, immunocytochemically and ultrastructurally. The relationship to so-called “carcinoid” mammary tumors is discussed.

    Description / Table of Contents: Zusammenfassung An der Metaphysencorticalis der Rattentibia wurde die Entwicklung des Osteocyten mit Hilfe seiner Alters-Lage-Beziehung im Knochen untersucht. Die funktioneilen Veränderungen des Osteocyten und seiner pericellulären Strukturen charakterisieren die verschiedenen ultrastrukturell faßbaren Entwicklungsstadien der Knochenzelle. Aus dem Osteoblasten entsteht über den Matrixosteocyten der junge Osteocyt, der an der Mineralisationsfront der neugebildeten Knochenmatrix liegt. Durch komplette Mineralisation der perilakunären Matrix entwickelt sich der reife Osteocyt. Dieser kann phasisch verschiedene Funktionszustände (inaktiv, formativ, resorptiv) annehmen oder degenerieren. Endstadium ist die Leere Lakune mit Einschluß von Zellresten und Kollagenfasern, die teilweise mineralisieren. Die Kenntnis der aufgeführten Stadien gestattet die Beurteilung experimenteller Veränderungen.
    Notes: Summary Osteocytic development was studied in cortical bone of the tibial metaphysis in the rat, with respect to the relationship between age and localization of the cells. The different development stages through which the osteocytes pass during their life cycle are characterized by functional alterations of the osteocyte itself, as well as pericellular structures of bone substance. The osteoblasts, surrounded by bone matrix, are transformed to matrix osteocytes and then to young osteocytes. The young osteocytes are situated at the mineralization front of newly formed bone matrix. The osteocyte matures through complete mineralization of the perilacunar bone matrix. The mature osteocyte may acquire different functional aspects (inactive, formative, resorptive) or degenerate. The final phase is the empty lacunae, which is mineralized by micropetrosis.

    Description / Table of Contents: Zusammenfassung Die noduläre lokalisierte Synovitis ist ein gutartiger Tumor, der von der Synovialis ausgeht. Die umschriebenen Knoten sind charakterisiert durch mehrkernige Riesenzellen, die mit proliferierenden Histiocyten vergesellschaftet sind. Es besteht eine histiogenetische Beziehung zur diffusen pigmentierten villonodulären Form. Die Behandlung besteht in der Excision des kompletten Knotens.
    Notes: Summary Localised nodular synovitis is a benign tumour which originates from the synovia. The circumscribed nodules are characterised by multinucleated giant cells associated with the proliferation of histiocytes. There is a histiogenetic relationship to the diffuse, heavily pigmented, villo-nodular form. The treatment consists in excising the complete nodule.

    Notes: Abstract The wound phloem bridges which have developed six days after interrupting an internodal vascular bundle contain wound sieve-elements, companion cells, and phloem parenchyma cells. An analysis of the meristematic activity responding to the wounding clearly demonstrates that three consecutive divisions are prerequisite to the formation of phloem mother-cells. Companion cells are obligatory sister cells of wound sieve-elements, connected to the latter by specific plasmatic strands and provided with a dense protoplast. Six days after wounding most of the wound sieve-elements are still at a nucleate state of development, but already have characteristic P-protein bodies and plastids containing sieve-element starch. Their cytoplasmic differentiation corresponds to the changes recorded during maturation of ordinary sieve elements. Sieve-plate pores penetrate through preexisting parenchyma cell walls, only, and develop from primary pitfield-plasmodesmata. Wound sieve-elements do not connect to preexisting bundle sieve-elements, they open a new tier of young sieve elements produced by cambial activity.

    Notes: Abstract The broadspectrum herbicide glyphosate (N-[phosphonomethyl]glycine), an inhibitor of the shikimate pathway enzyme 5-enolpyruvyl-shikimic acid-3-phosphate (EPSP)-synthase, inhibits the growth of Aerobacter aerogenes and causes the excretion of shikimic acid-3-phosphate. A strain of A. aerogenes, resistant to inhibition of growth by glyphosate, was isolated and found to have a glyphosate-insensitive EPSP-synthase and to no longer excrete shikimic acid-3-phosphate in the presence of glyphosate. Partial identity of EPSP-synthases from the glyphosate-sensitive and-resistant A. aerogenes strains was demonstrated by immunological procedures.

    Notes: Summary In experimentally-induced wound phloem, sieve-element plastids express their genetically determined type in depositing amylopectinrich sieve-tube starch (Coleus, S-type) and polygonal protein crystals (Pisum, P-type). Sieve-element plastids budd off from preexisting amyloplasts, pass through a short amoeboid state and develop into spherical plastids with translucent matrix. During early phases of differentiation wound sieve-elements contain two populations of plastids: typical sieve-element plastids and residual parenchyma plastids with large amylose-rich starch grains. The retardation in the break down of the latter is discussed. Sieve-tube and amyloplast starches are likewise digested by α-1,4- and α-1,6-bond cleaving glucosidases.
