A process for the investigation of an active ingredient influence on biological cells

摘要

In the case of a process for the investigation of the active substance effect on cells, these are on a sample carrier (13, 14) immobilized, the in a reaction chamber (12) is accommodated. By the action of the reaction chamber with the active substance (for example, in the nutrient solution for the cells contain) can be electrical signals via the electrically conductive sample carrier (14) is read out, the a conclusion on the electrical properties of the cells (11) permit. In this way, especially a dying of the cells to be determined, as a result of which the toxic effect of the active ingredient can be investigated. As a result of this examination, the otherwise necessary tests on animals limited or even be dispensed with (customary ld50 - toxicity).
