    Description / Table of Contents: Zusammenfassung Morphin und Codein wurde mittels C18-Säulenextrak-ktion isoliert und mit Pentafluorpropionsäureanhydrid (PFPA) derivatisiert. Die PFPA-Derivate wurden gaschromatographisch und massenspektrometrisch untersucht und hinsichtlich ihrer optimalen Nachweismöglichkeit verglichen. Aufgrund unserer Untersuchungsergebnisse ist die C18-Säulenex-traktion in Kombination mit der negativ-chemischen-Ionisation (NCI) besonders zum Nachweis von derivatisiertem Codein und Morphin geeignet. Die Bestimmungsgrenze liegt derzeit bei etwa 2 bis 5 μg Morphin oder Codein pro Liter Blut.
    Notes: Summary Morphine and codeine were isolated from blood with C18 Bond Elut columns and derivatised with pentafluoropropionic anhydride (PFPA). The PFPA-derivatives were examined by means of gas chromatography/mass spectrometry using electron impact and chemical ionisation (positive and negative mode). The negative chemical ionisation, as most sensitive, was applied for the quantitation of both examined substances in forensic blood samples.

    Notes: Proteins of dog bronchoalveolar lavage fluid, obtained by washing the epithelial lining layer of lungs with phosphate-buffered saline, were separated by two-dimensional electrophoresis. Due to the low protein and high salt content of the bronchoalveolar lavage fluid, samples had to be concentrated and desalted. Following electrophoresis the protein spots were visualized by silver staining. Comparing the two-dimensional protein patterns of bronchoalveolar lavage fluid with that from serum, several lungspecific proteins were detected. The most prominent protein, most probably a surfactant-associated protein, showed isoforms with isoelectric points in the range of pH 4.2-4.8, and a molecular mass of 32 kDa on sodium dodecyl sulfate-polyacrylamide gel electrophoresis after reduction with dithiothreitol.
