    Description / Table of Contents: Zusammenfassung Wir untersuchten die Frage, ob es gelingt, mit einer hypothermen Leberperfusion therapeutisch wirksame Cytostaticakonzentrationen im Gewebe zu erzeugen. In Lebern von SD Ratten wurden durch direkte Zellinoculation Walker Tumore erzeugt. Die Lebern wurden in situ mit verschiedenen Konzentrationen von Doxorubicin hypotherm perfundiert. Die Konzentrationen im tumortragenden Gewebe korrelierten direkt mit der Perfusionsdauer und der Perfusatkonzentration. Die hypothermen Cytostaticaperfusionen haben einen deutlichen therapeutischen Effekt. Ein entscheidender Vorteil des vorgestellten hypothermen Verfahrens ist der geringere apparative Aufwand bei vergleichbarem therapeutischen Effekt.
    Notes: Summary We were interested whether hypothermic drug perfusion would yield an effective concentration of a cytotoxic drug in tumor-bearing rat livers. Walker tumors were inoculated by a single injection of diluted cells into one liver lobe. The livers were perfused in situ with various concentrations of doxorubicin. The concentrations found in the liver correlated well with the perfusion time and the drug concentration in the perfusate. The hypothermic isolated liver perfusions showed a marked therapeutic effect. A major advantage of this approach is the simplicity of the hypothermic perfusion device compared with normo- or hyperthermic devices with a similar therapeutic effect.
