    Description / Table of Contents: Zusammenfassung 1. Ausgehend von grundlegenden experimentellen Fakten der Strahlenbiologie werden die Unterschiede zwischen Einzelzellen und Geweben behandelt, wobei vor allem auf Regelungsvorgänge, die auf die Konstanthaltung der Zellzahl hinwirken, eingegangen wird. 2. Es wird ein allgemeines Schema für Einteilung von Zellpopulationen vorgeschlagen, zu welchem als Klassifizierungsmerkmal die Art und Weise homöostatischer Regelungen der Zellzahl herangezogen wird. Die Einwirkung ionisierender Strahlung auf diese Modellsysteme wird diskutiert. 3. Mit Hilfe verschiedener Annahmen wird versucht, die unterschiedliche Strahlenempfindlichkeit verschiedener Organe zu deuten.
    Notes: Abstract Starting with experimentally established radiobiological facts concerning cellular effects of ionizing radiation, the differences between single cells and tissues are discussed. A new classification for “size”-controlled tissues is proposed, and the relevant mathematical formulations are outlined. It is suggested that the different sensitivities of tissues against ionizing radiation may be explained on the basis of differently operating control mechanisms. As examples, root meristems, intestinal epithelium and blood forming organs are described in more detail.

    Description / Table of Contents: Zusammenfassung Der mathematische Formalismus zur Beschreibung des Wachstums von Zellpopulationen wird beschrieben. Dabei kommen sowohl deterministische Verfahren, welche nur Aussagen über das zeitliche Verhalten der Erwartungswerte erlauben, als auch stochastische Ansätze, die zufallsbedingte Schwankungen miteinbeziehen, zur Anwendung. Exponentiell wachsende als auch stationäre Populationen werden behandelt; es wird gezeigt, daß der stochastische Ansatz einiger Modifikationen bedarf, um den experimentell gefundenen Realitäten Rechnung zu tragen. Hierzu wird ein allgemeines stochastisches Modell des Zellzyklus eingeführt.
    Notes: Summary The mathematical formalism for the description of cell proliferation is outlined. Deterministic approaches yielding only results for the time behaviour of expectation values as well as stochastic methods allowing for random fluctuations are introduced. Both exponentially growing and stationary populations are investigated. It is shown that the simple stochastic approach has to be modified to match theory and experimental results. To this end a general stochastic model of the cell cycle is suggested.

    On the immunological detection of X-ray induced DNA damage (1981)
    Springer
    Radiation and environmental biophysics 19 (1981), S. 259-264

    Notes: Summary Denatured calf-thymus DNA was X-irradiated, coupled to methylated bovine serum albumin and injected into rabbits to study the possible formation of specific antibodies. The serological activity was tested by a modified Farr-test, a micro complement binding reaction and by caesium chloride isopycnic ultracentrifugation. It was found with all assays that the immunological reaction was mainly due to unspecific DNA-binding and only a very small amount to radiation products. It seems, therefore, that this approach is not suitable for the analytical investigation of DNA damage produced by ionizing radiation.

    Notes: Abstract Experiments with accelerated heavy ions may contribute to the understanding of biological radiation action. After outlining the theoretical background experiments are described which were carried out at the UNILAC-machine (Gesellschaft für Schwerionenforschung, Darmstadt, Germany) where ions up to uranium can be accelerated to maximal specific energies of 10 MeV/u. Yeast cells served as biological test systems with the synthesis of ribosomal RNA (r-RNA), colony-forming ability and mutation induction as experimental endpoints. A relationship between action and energy deposition by individual particles can be demonstrated for the inhibition of r-RNA synthesis, in other cases the ion energy plays also an important role indicating that the interaction of δ-electrons from different particles contributes significantly to the biological effect.

    Cellular radiation effects and hyperthermia cell cycle kinetics of radiation sensitive mutants of Saccharomyces cerevisiae after X-irradiation and hyperthermia (1983)

    Radiation and environmental biophysics 22 (1983), S. 269-280

    Notes: Summary Radiosensitive mutantsrad2, rad9, andrad51 of Saccharomyces cerevisiae were X-irradiated with 120 Gy or 60 Gy, heated at 50° C for 30 min or treated with a combination of both and incubated in nutrient medium at 30° C. Cell number, percentage of budding cells, and cell cycle progression were determined in 45-min intervals. Cell cycle kinetics were investigated by flow cytofluorometry. Hyperthermia leads mainly to a lengthening of GI, whereas X-rays arrest cells of therad2 andrad9 mutant in G2 and therad51 - mutant additionaly in a state with DNA contents above G2. Cell division delay is influenced by oxygen in all strains but to a lesser extent in therad2 mutant. The effect of the combined treatment appears to be merely additive in therad2 andrad9 mutant while therad51 mutant is sensitized to X-irradiation by hyperthermia. No selective action of hyperthermia on hypoxic cells was found.
