  • Title: [Basic study on hepatic artery chemoembolization and tumor selective drug targeting by temperature-sensitive liposome with local hyperthermia].

    Abstract:
    Temperature-sensitive liposome entrapping adriamycin (L-ADM) was administered into the hepatic artery of hepatic tumor-bearing rats. The embolization of the hepatic artery with liposome and bio-distribution of ADM were examined. ADM concentration in blood showed a peak at 30 min after local heating on tumor (the heating had been performed for 6 min at 41-42 degrees C 2 hr. after injection). The value at the peak was about 3 times higher than that just before heating. ADM administered in liposomal form showed a high accumulative property to tumor with heating; ADM concentration in tumor 8 hr. after administration of ADM in liposomal form was about 5 times higher than that in liver and about 30 times higher than that in the heart, and about 20 times higher than that in tumor after administration in free form.
