摘要: 应用自己研制的99mTc—DX淋巴管显像药盒,对不同处理的动物进行了病理与显像结果分析。选用DX分子量为48,000。注射剂量0.1ml,放射强度0.5mci。大鼠注射尾静脉,小鼠于趾间皮下注射。用单光子发射计算机断层仪(SPECT)分别观察显像情况,并进行病理对比。结果表明:大鼠尾静脉注射后,肝、肾显像清晰。正常小鼠显像淋巴链完整,影像对称;患瘤小鼠局部淋巴通常受阻,淋巴链不完整,影像两侧不对称。显像结果与病理观察相同。研究结果提示:99mTc—DX药盒除适用于临床推广应用外,还适用于实验动物肿瘤模型的诊断、肿瘤淋巴转移的预测、肿瘤术后的观察及肝癌导向治疗等实验研究。

Abstract: "We observed image state of the rats and mice with 99 mTc-DX that were made by ourself. The usefulness of 99 mTc-Dextran with a molecular weight of 48,000,injection size of 0.1 ml(0.2~0.5 mci) .Rat injected site from the tail vein, mice injected site from the skin of hind or front interdigits, the animal observed imaging with SPECT. The results yielded high-quality scintigraphy of the liver, kidney in rat and radionuclide of the mouse. We conclude that 99 mTc-DX is a very promising agent for lymphoscintigraphy. Animals as well as pilot studies in man produced high-contrast images of the lymph system. The potential value of this new radiopharmaceutical for diagnosis and follow-up of animal with cancer, cancer lymph metastasis, and animal laboratory studies of targeting therapy on liver cancer. "
