Results:(1) The 90Y activity was higher while the contumination of 90Sr was less than 0.0031%;(2) The efficiency of 90Y-labeled antibodies was over 90%,the activity of labeled antibody maintained 82.3%;(3) Tumor size of all 90Y-antibody-treated model was significantly less than that of all 90Y-Cl3-treated model, the average survival time of the mice of the 90Y-antibody-treated group was significantly longer than that of the 90Y-Cl3-treated group;(4) In the tissue sections extensive necrosis was observed in all 90Y-antibody-treated tumor, the living tumor cells were immunohistochemically stainable with PcNA.

结果：(1)EDTA淋洗法制备90Y纯度高，其相对含量可达99.997％；(2)单克隆抗体的90Y标记率达90％以上，抗体蛋白活性保持82.3％；(3)治疗结果表明治疗组肿瘤明显小于对照组，原肿瘤的指数生长规律遭到破坏，治疗组生存期明显长于对照组；(4)组织学切片显示治疗组肿瘤有广泛坏死，PcNA免疫组化显示治疗组肿瘤细胞增殖受到明显抑制。

METHODS: The breast cancer cell lines Bcap37 were treated with different concentrations of vinblatine dissolved in dimethyl sulphoxide or caspase-3 inhibitor (DEVD-CHO, 100 μmol/L) for 3 h. The changes of the proliferation were detected by MTT methods. The apoptosis was determined by observing the internucleosomal DNA cleavage and PI staining, and the proteins of pro-caspase-3 and IκΒ-α were detected by Western blotting methods.
