  • In East Germany ambient air pollution is characterized by high concentrations of sulfur dioxide (SO{sub 2}) and suspended particulates (SP). Since acidity and sulfate are surprisingly low, oxidation of SO{sub 2} seems to be incomplete and neutralization seems to play an important role. Few studies on health effects of air pollution in the former German Democratic Republic have been performed. They showed an increased prevalence in polluted areas of respiratory symptoms, lung function decrement, mild anemia, nonspecific stimulation of the immune system and, retardation of skeletal maturation of children. Since the German unification in 1990, several large-scale studies have beenmore » started. Short-term effects of air pollution on daily mortality have been investigated in Erfurt retrospectively for 1980 to 1989. Logarithmic exposure-effect curves have been found for both SO{sub 2} and SP. The number of deaths increased by about 10% with SO{sub 2} and by more than 20% with SP if the 95th percentile of the pollutant is compared to the 5th percentile. The logarithmic shape shows that the increase of ambient concentrations at the beginning of the heating season in fall is more important than further increases in concentrations later in winter. A second study on short-term effects was conducted using daily peak flow measurements and respiratory symptoms in 270 patients with asthma and other obstructive airway diseases in East Germany and the Czech Republic between 1990 and 1992. From regression analysis it follows that an increase by 500 {mu}g/m{sup 3} of SO{sub 2} leads to a mean decrease of the average patient`s peak flow below 2%. Three cross-sectional studies are in progress to compare the existing respiratory health status in East and West Germany. They consider about 9000 adults (20-44 years of age), 9000 school children (9-11 years of age) and 10,000 preschool children (age 6). Analysis is ongoing. 40 refs., 4 figs., 6 tabs.« less
  • With the development of megavoltage treatment and computerized treatment planning the quality and precision of radiation oncology has steadily improved. Likewise, these developments have contributed to better local control for some cancers; however, micrometastatic lesions beyond the radiation treatment field and ineffective systemic treatments for many malignancies hamper efforts at the most important oncological end point, survival. Major advances in cancer therapy are therefore likely to come with improved combined modality treatment representing integration of local modalities with the systemic. These advances, in our opinion, will come from biological developments that address the problems that the modern oncologist faces atmore » the cellular level. The biological developments will incorporate modern molecular biology, continued probing for biochemical mechanisms, and an intensified effort to learn more about the complexities of human tumor physiology. 63 references.« less
  • The results are reported of a search for evidence of mass loss from three very hot, helium-rich degenerate stars, PG 1034 + 001, PG 1159 - 035, and KPD 0005 + 5106, based upon a search for weak, velocity-displaced line features in high-resolution IUE spectra. The search was entirely negative for PG 1159 - 035 and resulted in the detection of Si IV in PG 1034 + 001 at the same redshifted velocity as the other detected far-ultraviolet resonance doublets. The presence of photospheric silicon in a DO star at 80,000 K is not predicted by current radiative acceleration theory.more » For KPD 0005 + 5106 there is no convincing far-ultraviolet spectroscopic detection of either past or ongoing mass loss. The high-ionization resonance doublets of C IV, Si IV, and N v share the same velocity broadening as the interstellar lines but are velocity displaced by + 10 km/s relative to the local interstellar medium. Their origin is ascribed to an expanding, photoionized H II region around KPD 0005 + 5106. 21 refs.« less
