A process for the investigation of the action of a gaseous medium to a biological test system with the use of an extracellular metabolization system as well as apparatus for carrying out the method

摘要

The present invention relates to a method for investigating the effect of a gaseous medium to a biological test system with the use of an extracellular metabolization system, comprising the following method steps:- 018 Of a biological test system on a permeable carrier- Passing the gaseous medium over the surface of the biological test system for the formation of an exposure atmosphere above the biological test system- Addition of the extracellular metabolization system to a conservation medium- Positioning of the conservation medium with extracellular metabolisation of the system below the permeable support with contact with the permeable carrier, in such a way that the extracellular metabolization system, only by the permeable carrier passage, the biological test system, however, not from the conservation medium with extracellular metabolization system is flooded.
