    Notes: Abstract  Mutations causing a visible phenotype in the adult serve as valuable visible genetic markers in multicellular genetic model organisms such as Drosophila melanogaster, Caenorhabditis elegans and Arabidopsis thaliana. In a large scale screen for mutations affecting early development of the zebrafish, we identified a number of mutations that are homozygous viable or semiviable. Here we describe viable mutations which produce visible phenotypes in the adult fish. These predominantly affect the fins and pigmentation, but also the eyes and body length of the adult. A number of dominant mutations caused visible phenotypes in the adult fish. Mutations in three genes, long fin, another long fin and wanda affected fin formation in the adult. Four mutations were found to cause a dominant reduction of the overall body length in the adult. The adult pigment pattern was found to be changed by dominant mutations in wanda, asterix, obelix, leopard, salz and pfeffer. Among the recessive mutations producing visible phenotypes in the homozygous adult, a group of mutations that failed to produce melanin was assayed for tyrosinase activity. Mutations in sandy produced embryos that failed to express tyrosinase activity. These are potentially useful for using tyrosinase as a marker for the generation of transgenic lines of zebrafish.

    Description / Table of Contents: Zusammenfassung Prospektive immunologische Untersuchungen in der bronchoalveolären Lavage, im Blut und im Urin bei Polytraumatisierten sollten Marker zur Erkennung der Frühphase der Sepsis aufdecken. Die Sepsis begann bei 7 Patienten initial mit einer alveolären Zellaktivierung (Veränderung der Zellzahl und -funktion) durch Mediatorsubstanzen (Elastase, Komplementspaltprodukte, Àrachidonsäuremetabolite). Die Organschäden von Lunge, Niere, Leber und Herz-Kreislauf entwikkelten sich im Sinne von sekundären Funktionsstörungen erst 4 Tage später. Durch die Frühdiagnostik solcher Veränderungen konnten frühe therapeutische Konsequenzen eingeleitet werden.
    Notes: Summary Prospective immunological monitoring using bronchoalveolar lavage, as well as urine and blood tests in patients with multiple injuries, revealed early signs of sepsis development. Sepsis initially began in 7 patients with alveolar cell activation and capillary leakage. Lung, kidney, liver, and heart failure occurred 4 days later in the form of secondary functional disturbances. These early diagnostic signs made appropriate therapy possible.
