The cytostatic drugs Chlorambucil and Bleomycin were labeled with 131I and with 57Co, respectively: Ruthenocenealdehyde-(N-methyl-N-beta-chlorethyl)-hydrazone and Ruthenocene-3-phenyl-prop.1-en-3-one were labeled with the gamma emitter 103Ru. In tumor-bearing mice the elimination and organ distribution of these radioactive substances were tested after intravenous (i.v.) and intratumoral (i.t.) injection of the drugs. The organ load showed lower values after i.t. than after i.v. application, while the radioactivity concentrations in the tumor were considerably increased after i.t. injection. The integrals of the concentration-time curves showed 10--80 times higher concentrations in the tumor after i.t. compared to i.v. injection of the drugs.
细胞抑制药物苯丁酸氮芥和博来霉素分别用¹³¹I和⁵⁷Co进行标记:钌茂醛 -(N - 甲基 - N - β - 氯乙基) - 腙和钌茂 - 3 - 苯基 - 丙 - 1 - 烯 - 3 - 酮用γ发射体¹⁰³Ru进行标记。在荷瘤小鼠中,静脉内(i.v.)和瘤内(i.t.)注射药物后,对这些放射性物质的消除和器官分布进行了测试。与静脉内给药相比,瘤内给药后器官负荷值较低,而瘤内注射后肿瘤中的放射性浓度显著增加。浓度 - 时间曲线的积分显示,与静脉内注射药物相比,瘤内注射后肿瘤中的浓度高10 - 80倍。
