    Notes: Abstract In order to assess if an oxidant/antioxidant imaalance is involved in human septic shock and its outcome, we measured plasma levels of the lipid peroxides malondialdehyde—as thiobarbituric acid reactive substance—conjugated dienes and fluorescent products, together with the antioxidants alpha-tocopherol, glutathione peroxidase activity and selenium in 12 patients with septic shock and compared them with values of normal controls. At first measurements, malondialdehyde (median 3.9 μmol/l; range 2–38.8) and fluorescent products (median 21.2%; range 9.4–134) were elevated (p〈0.05), alpha-tocopherol (median 15 μmol/l; range 7–25) and selenium (median 0.76 μg/ml; range 0.49–1.09) were depressed (p〈0.05). Conjugated dienes and glutathione peroxidase activity were in the normal range. In non-survivors (n=5) initial levels of malondialdehyde and fluorescent products (median 11 versus 3.1 μmol/l; 74 versus 135 respectively) were higher than in survivors (p〈0.05) and initial selenium levels were lower (median 0.58 versus 0.92 μg/l;p〈0.05). These results are consistent with the concept that an oxidant/antioxidant imbalance—as indicated by elevated plasma lipid peroxides and depressed antioxidants—is involved in human septic shock and a fatal outcome.

    Notes: In der Nähe des kritischen Zustandes bildet sich infolge der hohen Kompressibilität in einem ruhenden fluiden Medium eine mit der Höhe veränderliche Dichte aus. Diese Dichteschichtung wurde an CO2, N2O und CF3Cl sowie an Gemischen aus diesen Stoffen über die örtliche Brechzahl bestimmt. Die Versuchsapparatur wurde besonders sorgfältig auf konstanter Temperatur gehalten, so daß einwandfreie Gleichgewichtszustände erzielt wurden. Aus den Ergebnissen lassen sich die Grenzkurve, die Dampfdruckkurve und das Druck-Dichte-Diagramm in der Nähe des kritischen Zustandes mit größerer Genauigkeit bestimmen, als es durch die bisher übliche Messung von Mittelwerten der Dichte möglich war.
