Zur korrelation der in vivo- und in vitro-wirkung von cytostatika auf transplantationstumoren der maus

Abstract

In 2 inoculated mouse tumours the conformity of the actions of 4 different cytostatics at 2 dose levels was tested in vitro and in vivo. The histochemical reaction of lactate dehydrogenase and NADH diaphorase was taken as a criterion of the cytostatic action. The investigations showed the tumours used responded to the cytostatics employed. A good conformity of the in vitro and in vivo findings was established. The histochemical assessment of organ cultures following the administration of cytostatics allows to determine the sensitivity of tumours and helps the physician in deciding on an effective therapeutic.
