| Research Abstract |
We analyzed in vitro and in vivo antitumor effect of the mixture of zoledronic acid and phosphorylated pullulan for human breast cancer cell line. The elution of zoledronic acid released from phosphorylated pullulan exhibited antitumor effect. Phosphorylated pullulan exhibited a drug release property for zoledronic acid. The local administration of the mixture of the mixture of zoledronic acid and phosphorylated pullulan into the metastatic bone tumor model of nude mice exhibited antitumor effect. Furthermore, bone formation was observed around the mixture.
