    Notes: Abstract Peripheral blood lymphocytes from 36 patients with advanced periodontitis and from 34 healthy subjects were examined using a panel of monoclonal antibodies and fluorescence flow cytometry. The absolute and relative counts of B-cells, T-cells, T-helper (TH), T-suppressor/cytotoxic (TS) cells, activated T-cells and natural killer cells were assessed and the TH/S ratio was calculated. In the periodontitis patients, the TH/s ratio was 1.56 ± 0.62 and in the controls 1.35 ± 0.55. This was not statistically significant. A classification on the basis of sex also did not show significant differences in the TH/S ratio. B-cells and activated T-cells were slightly increased in the periodontitis group. However, all determined lymphocyte subpopulations revealed no significant differences between the groups. These results indicate that local inflammatory reactions and immunoregulatory dysfunction are limited to the periodontium in the patients with advanced periodontitis, with no significant quantitative effects on the peripheral lymphocyte subpopulations.

    Description / Table of Contents: Zusammenfassung Mit der125J-Clq-Deviationsmethode nach Sobel, dem Polyethylenglykol-Präzipitationstests nach Nydegger und einer Sepharose 6B-Säulenchromatographie in Anlehnung an MacLennan wurden zirkulierende Immunkomplexe (ZIK) bei 20–27% der Patienten mit Hodgkin-Lymphomen, bei 8% der Patienten mit Nicht-Hodgkin-Lymphomen vom niedrigen und in 20–40% vom hohen Malignitätsgrad nachgewiesen. ZIK traten in fortgeschrittenen Stadien der Erkrankungen auf und korrelierten gut mit der Krankheitsaktivität. ZIK verschwanden in der Remission und erschienen im Rezidiv wieder. ZIK wurden nur bei Patienten mit allgemeinen Symptomen, d. h. mit B-Symptomen, gefunden. Die pathogenetische Rolle der ZIK bei der Entstehung der B-Symptome und bei der Tumorausbreitung ist noch nicht end gültig geklärt. Der Antikörperanteil der ZIK ist IgG, die antigene Komponente wurde nicht charakterisiert.
    Notes: Summary Using the125J-Clq deviation method according to Sobel, the polyethylenglycol precipitation test of Nydegger, and a Sepharose 6B column chromatography in a modification of MacLennan's method, circulating immune complexes (CIC) have been detected in 20–27% of patients with Hodgkin's lymphoma, in 8% of patients with non-Hodgkin lymphoma of low, and in 20–40% with high malignancy. CIC appeared in advanced stages of the diseases and correlated well with the activity of the disease. CIC disappeared in remissions and reappeared during reactivation of the disease. CIC were only found in patients with general symptoms, i.e. B-symptoms. The pathogenetic role of CIC in the initiation of B-symptoms and in tumor spread is still not fully explained. The antibody part of the CIC is IgG, the antigenic component has not yet been characterized.

    Notes: Summary The cell line 5637 which originated from a human urinary bladder carcinoma is known to produce GM-CSF and Multi-CSF ectopically. Determination of cell surface antigens defined by monoclonal antibodies was recently reported [6]. Here we report on the ultrastructure and karyology of this CSF secreting cell line. At the ultrastructural level the monolayer in vitro culture and the solid tumors formed in nude mice showed all characteristics consistent with a well-differentiated transitional cell carcinoma (TCC). A subclone was found to grow in suspension and did not secrete any CSF activity. High resolution chromsome analysis revealed chromosomal abnormalities which agreed only in few particulars with nonrandom chromosomal aberrations usually found in TCC. Analysis of the cytogenetic results showed that nearly all structural abnormalities present are known to be associated with acute or chronic human leukemia. The possibility that the ectopic production of CSF in this cell line may be correlated to one or more of the described chromosomal aberrations is discussed.

    Notes: Summary Patients with small cell carcinoma of the lung (SCCL) were treated in two multicenter trials with different cytostatic drug regimens including ifosfamide. In the first randomized study, including 306 patients, alternating chemotherapy with VP 16, ifosfamide, vindesine (VPIV), adriamycin, cisplatinum, vincristine (APO), and cyclophosphamide, methotrexate, CCNU (CMCC) was compared against standard treatment with ACO (adriamycin, cyclophosphamide, vincristine). It was shown that the alternating therapy resulted in a higher response rate (88% vs 78%) and a longer median survival time (11 months vs 10 months). Regarding toxicity, VPIV was similar to ACO, whereas APO and CMCC had more side-effects, leading to an increase in the number of drop-outs. In the second randomized study 144 patients were treated either with ifosfamide/VP 16 (IVP) or with cisplatinum/VP 16 (PVP). In the case of no further response, no change, or progression the induction therapy was changed to ACO. Interim analyses show that both regimens have similar therapeutic effects; but higher toxicity was observed in patients treated withcis-platinum/VP 16 than in patients treated with ifosfamide/VP 16. According to the response rate in patients treated with ACO after first-line therapy there was less cross-resistance of IVP than of PVP to ACO.

    Description / Table of Contents: Zusammenfassung Das Vorkommen erhöhter Serumspiegel von immunreaktivem Calcitonin (CT) wurde bei menschlichen myeloproliferativen und lymphoproliferativen Erkrankungen untersucht. Unter Zugrundelegung des doppelten oberen Normalbereiches zeigten etwa 45% der Patienten mit akuter Leukämie und mit Blastenschub bei chronischer myeloischer Leukämie erhöhte Calcitonin-Serumspiegel. Extrem erhöhte Werte (〉 1000 pg/ml) waren nur in dieser Patientengruppe nachweisbar. Mit dem Eintritt einer Remission kam es zu einem Abfall oder einer Normalisierung der CT-Werte, während bei Eintreten eines Rezidivs ein frühzeitiger Wiederanstieg beobachtet wurde. Dies läßt annehmen, daß die Serumspiegel die Aktivität der Erkrankung wiedergeben. Bei Patienten mit chronischen Leukämien, Morbus Hodgkin und Nicht-Hodgkin-Lymphomen war die Häufigkeit und das Ausmaß der Calcitoninerhöhung im Serum deutlich geringer. Darüber hinaus wurde die Molekulargewichtsverteilung des Proteohormons in Serumproben und Zellextrakten durch Gelchromatographie untersucht. Neben dem physiologischen Hormon fanden sich unterschiedliche hochmolekulare Formen im Serum und in Milzzellextrakten. In Leukämiezellextrakten war ausschließlich hochmolekulares Calcitonin nachweisbar. Es wird angenommen, daß Calcitonin ektop durch die leukämischen Zellen produziert wird.
    Notes: Summary The incidence of elevated serum levels of immunoreactive calcitonin (CT) in human myeloproliferative and lymphoproliferative disorders was investigated. On the basis of twice the normal range, about 45% of patients with acute leukemia and blast crisis of chronic myelocytic leukemia (CML) showed elevated serum levels of CT. Markedly elevated levels (〉 1,000 pg/ml) were only found in this group. Since immunoreactive CT dropped to normal or only slightly elevated levels in remission and increased again before or during relapse, serum CT levels seem to reflect the activity of the disease. However, in patients with chronic leukemia, Hodgkin's and non-Hodgkin's lymphoma, a lower incidence and only slightly elevated serum values were found. In addition, the molecular weight of the proteohormone in serum specimen and cell extracts was investigated by gel chromatography. Besides physiological CT, different high-molecular weight forms of the hormone could be demonstrated in serum and in cell extracts. Extracts of leukemic cells revealed higher molecular forms only. It is suggested that the proteohormone is ectopically produced by leukemic cells.
