    Description / Table of Contents: Abstract In fulfilling the commitment to the European Conferences on Environmental Health the Federal Ministry for Health and the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety presented a joint “Action Programme on Environment and Health”. The action programme is backed up by a comprehensive documentation presenting the current status and findings and providing justification for the proposed goals and measures. The programme covers the following subjects: environment health monitoring and reporting, information management, risk perception and risk acceptance, environmental medicine, measures to improve co-operation among competent national authorities, international co-operation. The programme also conveys media- and substance-oriented quality objectives, in particular concerning outdoor air and climate; indoor air; water resources, soil, food; ionising radiation; noise; substances and preparations. The programme is aimed at supporting the policy development in the field of environment and health. The planing of detailed steps and the programme's implementation will be performed in close co-ordination and co-operation of all parties interested/involved and afflicted/affected.
    Notes: Zusammenfassung Das gemeinsame Aktionsprogramm “Umwelt und Gesundheit” des Ministeriums für Gesundheit und des Ministeriums für Umwelt, Naturschutz und Reaktorsicherheit löst die eingegangene Verpflichtung ein, die aus den europäischen Umweltkonferenzen resultiert. Das Programm dient dem Ziel, eine Handlungsbasis aufzustellen, auf welcher der Gesundheitszustand der Bürger und Bürgerinnen in Bereichen sichergestellt wird, die durch ungünstige Einflüsse von Umweltnoxen physikalischer Natur, mediengetragenen Umweltnoxen oder durch Aufnahme beim Umgang mit Verbraucherprodukten des täglichen Bedarfs oder durch die Nahrung gefährdet sein können. Das Programm wurde auf dem Hintergrund eines ausführlichen Dokumentationsbandes erstellt, der den aktuellen Sach- und Erkenntnisstand ausführlich darstellt und damit die vorgeschlagenen Ziele und Maßnahmen inhaltlich begründet. Das Programm enthält folgende Themen: umweltbezogene Gesundheitsbeobachtung und -berichterstattung, Informationsmanagement, Umgang mit Risiken, Umweltmedizin, Verbesserung der bestehenden Behördenstrukturen und internationale Zusammenarbeit. Das Programm enthält zudem verschiedene medien- und stoffbezogene Qualitätsziele zu folgenden Themen: Außenluft und Klima; Innenraumluft; Wasserressourcen, Boden, Lebensmittel, ionisierende Strahlung; Lärm sowie Stoffe und Zubereitungen. Das Programm soll eine Arbeitsgrundlage für die weitere Entwicklung des Politikfeldes Umwelt und Gesundheit bilden. Die weitere Ausgestaltung um Umsetzung des Programms wird in intensivem Diskurs mit allen Beteiligten und Betroffenen erfolgen.

    Notes: Cell fusions have been used to determine the biological activity of the MPF complex in murine oocytes during their progression through anaphase and telophase to metaphase II. Oocytes (1) at metaphase I, (2) during the anaphase-telophase transition, or (3) at metaphase II were fused to germinal vesicle-staged (immature) oocytes. The hybrids were cultured for 1 h in the presence of db cAMP before fixation and nuclear evaluation. Metaphase! oocytes invariably induced germinal vesicle breakdown (GVBD) in the immature partner. By contrast, anaphase/telophase oocytes never induced GVBD in immature oocytes. The capacity to induce GVBD reappears after the formation of the second metaphase plate. In a second study, histone H1 kinase activity was measured during mouse oocyte maturation in single oocytes. H1 kinase activity was low in GV oocytes, increased sharply at MI, declined during anaphase and telophase and increased again at MII. After egg activation, H1 kinase activity was reduced to basal levels. These results provide direct evidence that a drop in activity of MPF in murine oocytes occurs concomitantly with the exit from metaphase I; MPF activity remains low until the cell re-enters metaphase.

    Notes: Bovine oocytes were irradiated at germinal vesicle (GV) or metaphase II (MI) stage, after Hoechst staining, with chromosomally focused UV-C (254 nm) or UV-A (〉 330 nm). UV-C irradiation at GV stage did not inhibit germinal vesicle breakdown (GVBD) or chromosomal condensation; spindle formation was abolished and maturation promoting factor (MPF) levels failed to increase. UV-A irradiation at GV stage caused meiotic arrest at anaphase I; MPF levels were lower than control. UV-C irradiation at MII stage led to subsequent abnormal parthenogenetic activation when MPF levels failed to decrease. A normal male but no female pronucleus was formed at fertilization. UV-A irradiation at MII stage also caused abnormal activation; MPF levels declined normally. A normal male and abnormal female pronucleus formed at fertilization. UV-A irradiation results have implications for oocyte evaluation during development using Hoechst staining. UV-C irradiation is a potential means for oocyte enucleation in nuclear transfer. © 1995 Wiley-Liss, Inc.
