[Hepatic artery and portal vein infusion of adriamycin in experimental liver metastasis].
Hepatic artery and portal vein infusion of adriamycin (ADM) to normal rabbit and the experimental liver metastasis model of VX2 tumor were discussed in this study. The concentration of ADM in the peripheral blood, liver, myocardium, lung of normal rabbit and metastatic tumor were measured in the HPLC method. There was no difference between arterial infusion and portal infusion in the normal rabbits. In the metastatic tumor, one hour after the infusion, concentration of ADM showed no difference between arterial and portal infusion, but two and three hours later, the concentration was significantly higher after portal infusion than arterial infusion. It was suspected that portal infusion would be more effective for liver metastasis. The number of tumor nodules for estimation of the anti-tumor effect on metastatic models was decreased significantly after arterial and portal infusion compared with the controls, but there was no statistical difference between arterial and portal infusion.
