title: [Suspension cultures of Ehrlich ascites tumor cells as a test system for the study of cytotoxic effects of anaesthetics (author's transl)].
abstract: Cultures of a permanently in suspension growing line of Ehrlich ascites tumor cells (EATC) were studied regarding their use as a test system for the determination of cytotoxic effects of anaesthetics. These cells, having a comparatively high reduplication rate, are cultured at 37 degrees C in vitro in a chemically defined liquid medium supplemented by 15% horse serum without agitation in a closed system. In order to detect drug effects on the cultures various cellular parameters can be determined due to the suspension character of the cultures without complicated preparatory measures, e.g. cell number or multiplication rate, cell volume, cell volume distribution. Moreover biochemical parameters, such as protein or nucleic acid content, may be estimated after centrifugation of the cultures separately in the cell sediment and the medium supernatant. Applying drugs of various pharmacological groups (cytostatic and anti-inflammatory drugs, local and general anaesthetics) the usefulness of some of these parameters for the detection of cytotoxic effects was studied.
