利用加热固化蛋白质原理制备出阿霉素磁性蛋白微球，比色法分析其细胞毒作用。结果显示阿霉素磁性蛋白微球具有磁性药物微球的形态学特征， 体外抑制肿瘤细胞生长的能力与阿霉素相似 （Ｐ＞ ０．０５）， 提示阿霉素磁性蛋白微球是抗癌药物阿霉素的一种新剂型，该药物剂型的改变未影响其体外药理作用，与磁场联用发挥靶向高效低毒的抗癌作用
Adriamycin magnetic protein microspheres were prepared by the principle of heat curing protein, and the cytotoxicity was analyzed by colorimetric method. The results showed that doxorubicin magnetic microspheres had the morphological characteristics of magnetic drug microspheres and the ability of inhibiting the growth of tumor cells in vitro was similar to doxorubicin (P> 0.05), suggesting that doxorubicin magnetic microspheres are anti-cancer A new dosage form of drug doxorubicin, which has no effect on the pharmacological effect in vitro and has the anticancer effect of targeting high efficiency and low toxicity in combination with a magnetic field
