    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.

    Small cell neuroendocrine (oat cell) carcinoma of the male breast (1984)
    Springer

    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 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.

    Fine structure, pattern of division, and course of wound phloem in Coleus blumei (1980)
    Springer

    Topics: Biology
    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.

    Description / Table of Contents: Zusammenfassung Der Wert der autologen Knochenspanverpflanzung bei Osteosynthesen von Frakturen, Pseudarthrosen und nach Kontinuitätsresektionen ist seit langem bekannt. Eine zusätzliche Bereicherung stellt dercorticospongiöse Rippenspan dar. In einer Bildfolge werden die Technik der Spanentnahme, der Spaneinbau histologisch und röntgenologisch, sowie dessen spätere Durchblutung gezeigt. Die Ergebnisse von 42 autologen Rippenspananlagerungen werden tabellarisch dargestellt.
    Notes: Summary The use of autogenous cortico-cancellous bone grafts to repair bone defects, to treat nonunion of fractures, and after continuity resection has proved to be a valuable technique. An additional method that can be used to fill extensive defects of bones is the apposition of corticocancellous rib grafts. Pictures illustrate resected rib grafts, histological and radiological checks, and later blood flow in the graft. The results of 42 appositions of autologous rib grafts are displayed in tables.

    The development of specific sieve-element plastids in wound phloem ofColeus blumei (S-type) andPisum sativum (P-type), regenerated from amyloplast-containing parenchyma cells (1983)

    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.
