    The distribution of fibronectin in lymph nodes infiltrated by Hodgkin's disease (1983)

    Notes: Summary The tissue distribution of fibronectin (FN) was examined using a commercial anti-FN serum, the peroxidase-anti-peroxidase (PaP) technique, and paraffin sections of 22 lymph nodes affected by Hodgkin's disease. Vascular basement membranes and reticulin fibres are selectively stained and their structural changes in this pathological condition become readily visible. In contrast to the normal lymph node and to Hodgkin's disease with lymphocytic predominance, cases of mixed cellularity disease contain individual and focally grouped cells displaying intracytoplasmic FN. In nodular sclerosis these cells with fibroblast morphology are consistently numerous in the marginal zones of the cellular nodes. Strongly reacting mastocytes probably absorbed the applied anti-serum non-immunologically. All the other cell types giving rise to the varying appearances of Hodgkin's lesions are consistently negative with respect to intracellular FN, including all forms of Hodgkin cells. We conclude that in Hodgkin's disease the immigration of FN-secreting fibroblasts is an integral part of the early sclerosing reaction, which in itself is a defence/repair mechanism closely related to scar formation.

    J-chain-producing immunoblastic lymphoma in a case of Richter's syndrome (1982)

    Notes: Summary A 66-year old male with Richter's syndrome died 52 month after diagnosis of chronic lymphocytic leukaemia (CLL). The clinical course was characterized by a marked IgM hypoglobulinaemia which paralleled a chronically relapsing Herpes simplex infection. Autopsy showed a large retroperitoneal and intraabdominal tumour mass and well defined supradiaphragmatic lymphomas. Histological examination revealed a composite tumour consisting of CLL B-cell type (B-CLL) and immunoblastic malignant lymphoma of B-cell type (B-IbL). The lymphocytes bear μ-chains on their surface and to a lesser extend within their cytoplasm, the obviously defective immunoblasts produce J chains exclusively. Flow cytophotometric data seem to indicate an identical diploid stem line of the two tumours. The majority of the cells are in G0/1 phase. The CLL rarely produces mitoses, however, the IbL has a mitotic rate of 7% and a considerable proportion (33%) of cells in the phase of DNA-synthesis. This is the fourth malignant lymphoma and the second immunoblastic lymphoma to be reported that produces J chain in the absence of immunoglobulin.

    Npm/alk fusion mRNA expression in Hodgkin and Reed–Sternberg cells is rare but does occur: Results from single-cell cDNA analysis (1997)

    Notes: Abstract Background: The translocation t(2;5)(p23;q35) leads to the fusion of the nucleophosmin gene (NPM) on chromosome 5q35 to the recently described receptor kinase ALK 2p23. It is characteristic of a subgroup of CD30+large-cell anaplastic non-Hodgkin's lymphoma (ALCL). Since some cases of Hodgkin's disease (HD) and ALCL share common features, a common pathogenesis has been proposed in a report of the expression of NPM/ALK fusion mRNA in11/13 Hodgkin's lymphomas. Patients and methods: We approached this question by micro manipulatory isolation of single Hodgkin and Reed–Sternberg (H-RS) cells and subsequent RT-PCR amplification of NPM/ALK fusion cDNA from these single cells. Results: Specificity of cell selection was shown by the HD-specific pattern of EBV-gene expression in single H-RS cells. In 4 out of 7 cases, NPM/ALK fusion cDNA was detected in the RNA from whole lymph node tissue. In2 out of 9 cases, NPM/ALK fusion sequences were amplified from single H-RS cells, albeit in a very low frequency (〈5%). Conclusions: These data indicate that NPM/ALK fusion transcripts do not play an early role in the pathogenesis of HD. Whether the rare expression of NPM/ALK is the result of clonal heterogeneity or an indication for clonal evolution and progression toward ALCL can only be answered by the repeated analysis of indicator cases during the course of the disease.

    Centroblastic lymphoma of the thyroid supervening long-lasting chronic lymphocytic leukemia (B-CLL) demonstration of biclonality by Immunohistochemical and gene rearrangement analysis (1988)

    Notes: Summary A 67-year-old woman suffering since 5 years from a so far nontreated B-CLL underwent hemithyroidectomy for a rapidly enlarging tumor. Histologically, the coincidence of a centroblastic lymphoma and thyroidal infiltration by the CLL was diagnosed. Immunohistology revealed typical immunoprofils for both, B-CLL and centroblastic lymphoma on the background of B cell differentiation antigens. The bitypical immunoglobulin light chain expression — λ on the B-CLL cells and κ on the centroblasts — suggested biclonality. This was confirmed by gene rearrangement analysis of peripheral leukemia cells and tumor tissue. Thus, the final diagnosis of a primary thyroidal lymphoma of the centroblastic type (stage IE) arising independently from a preexisting B-CLL was achieved. Consequently, the patient received local radiotherapy. In our opinion, the designation “Richter's Syndrome”, readily applied in the literature, is inappropriate for this tumor constellation.

    Oberflächenzusammensetzung, Löslichkeit und Ionenaktivitätsprodukt von Calcit in fremdionenhaltigen Lösungen (1974)

    Description / Table of Contents: Surface Composition, Solubility, and the Ion Activity Product of Calcite in Solutions with Auxiliary IonsUsing the method of simultaneous ion and isotope exchange the chemical composition of the surface layer of calcite powder in equilibrium with solutions of varying Me/Ca molar ratios is determined (Me = Mg2+, Co2+, Ni2+, and Fe2+ ions). The ion exchange isotherms show a marked bend in the surface reactivity when a surface molar ration of ∼1 and ∼3 is reached. The solubility of calcite initially decreases on the addition of Co2+ or Ni2+ ions to the solution whereas it increases in the presence of Mg2+ or Fe2+ ions. The activity product of the pseudo compound, CaxMe(1-x)CO3, decreases in the Ni2+, Co2+ or Fe2+ exchange experiments, however, it increases considerably in those with Mg2+ ions.
    Notes: Mit der Methode des gleichzeitigen Ionen- und Isotopenaustausches wird die chemische Zusammensetzung der Oberfläche eines Calcitpulvers im Gleichgewicht mit Lösungen verschiedener Me/Ca- Verhältnisse bestimmt (Me = Mg2+, Co2+, Ni2+, Fe2+). Alle Austauschisothermen zeigen eine deutliche Änderung der Oberflächenreaktivität, wenn eine Zusammensetzung auf der Oberfläche von (Me/Ca)Obfl.∼1 und ∼3 erreicht wird. Die Löslichkeit des Calcits nimmt anfänglich bei Zugabe von Co2+ oder Ni2+ ab, während sie bei Mg2+ oder Fe2+ im ganzen Bereich der Untersuchung zunimmt. Das Ionenaktivitätsprodukt für die „Pseudoverbindung“ in der Oberfläche nimmt in den Ni2+-, Co2+- und Fe2+-Austauschexperimenten ab, in Gegenwart von Mg2+-Ionen jedoch zu.
