摘要: 目的 观察羟基磷灰石-阿霉素抗癌复合物局部注射,阿霉素在体内的释放过程及其抗肿瘤作用。方法 在B 超引导下向兔肝左叶内注入羟基磷灰石-阿霉素抗癌复合物。应用荧光分光光度仪测定注射羟基磷灰石-阿霉素抗癌复合物后,阿霉素在组织及血浆中的浓度,并与无羟基磷灰石的对照组比较。结果 此复合药物可在组织中维持有效治疗浓度1000 ng·g-15 d 左右,同时与对照组相比注射后即时外周血浆浓度下降约1/2 。结论 该复合药物局部应用可提高及维持组织有效治疗浓度,减少毒副作用。

Abstract: Aim The release process of an anticancer agent,DOX-HAP in rabbit live r was observed.Methods DOX and DOX-HAP were separately injectoed into rabbit livers under the guide of Btypeultrasound.Dox concentrations in plasma and liver tissue of the rabbits in both groups were measured by fluorescent stectrophotometer and compared.Results The concentration of complex could existedin the liver tissue about 5 d(1 000 ng·g-1)when it was given in a dose of 2mg·g-1.At the 10 min the concentration in plasma would be reduced about 1/2 as compared with that in the control group.Conclusion sThe DOX-HAP complex not only could increase and insist in an effective concentration of DOX at the local injecting area of liver tissue,but also reduce its concerntration in the plasma.The refore,it could decrease the toxicity and side-effect of DOX.

Key words: doxorubicin(DOX), hydroxy patite(HAP), drug concentration
